1 | # LTDZ-DSP
2 |
3 | ## Project Goals
4 |
5 | LTDZ-DSP project is an attempt to improve the performance of this inexpensive
6 | 35MHz-4400MHz spectrum analyzer and tracking generator using only minimal
7 | hardware modifications, and by replacing the original firmware with this new
8 | version of the firmware, while maintaining the compatibility with the existing
9 | PC GUI applications.
10 |
11 | Summary of the project goals are as follows:
12 |
13 | 1. Improve the dynamic range of the scalar network analyzer from 50dB to 80dB.
14 |
15 | 2. Implement digital receiver bandwidth filters with selectable bandwidth,
16 | which allows better spectrum resolution in the spectrum analyzer mode.
17 |
18 | 3. Improve the linearity of the RMS/LOG-detector, providing more accurate
19 | and wider dynamic range up to 80dB.
20 |
21 | 4. Provide firmware source code which can be used for experimenting with
22 | the LTDZ board.
23 |
24 | ## Disclaimer
25 |
26 | The firmware source code is provided "as-is", without any support, without
27 | any guarantee of its correctness, or that the the firmware will perform as
28 | expected. In short: Use this firmware at your own risk.
29 |
30 | Please note: It may not be possible to read and create a backup for the
31 | original firmware, as the boards may be shipped with copy-protection enabled.
32 | So, keep in mind that you will most probably lose the original firmware.
33 |
34 | Finally, if you do not know how to use ST-Link programming tools, you will most
35 | probably end up with a bricked LTDZ board.
36 |
37 | ## Introduction
38 |
39 | LTDZ is an inexpensive 35MHz-4400MHz spectrum analyzer and tracking generator,
40 | readily available from various on-line sellers in price range USD $40 - $50.
41 |
42 | LTDZ provides three main operating modes:
43 |
44 | 1. Signal generator 35MHz - 4400MHz.
45 | 2. Spectrum analyzer 35MHz - 4400MHz.
46 | 3. Scalar network analyzer 35MHz - 4400MHz.
47 |
48 | The original LTDZ hardware and firmware provide approximately 50dB of dynamic
49 | range in spectrum analyzer operating mode and network analyzer operating mode.
50 | After a few and simple hardware modifications and a firmware update, the
51 | available dynamic range in the network analyzer mode can increased up to 80dB.
52 |
53 | In the spectrum analyzer mode, the original receiver bandwidth filter
54 | (RBW-filter) is fixed to 120kHz, which makes it practically impossible to
55 | make RF measurements requiring good spectral resolution. The new firmware
56 | provides a set of digital filters with variable bandwidths from 3kHz to
57 | 120kHz, depending on the step size used during spectrum sweep, providing
58 | much better spectral resolution.
59 |
60 | In the scalar network analyzer mode, the original receiver bandwidth filter
61 | (RBW-filter) is fixed to 120kHz, which results wide noise bandwidth, limiting
62 | the maximum dynamic range to 50dB. The new firmware implements a very narrow
63 | bandwidth receiver filter, providing dynamic range up to 80dB.
64 |
65 | The new firmware will bypass the on-board AD8307 LOG/RMS-detector with
66 | STM32F103's 12-bit ADC (analog-to-digital converter). Applying some simple DSP
67 | (digital signal processing), it is possible to implement highly linear, high
68 | dynamic range digital LOG/RMS-detector up to 80dB of dynamic range.
69 | The on-board, fixed 120kHz RBW-filter will be sampled by the ADC, and the new
70 | firmware will provide a set of digital filter with adjustable bandwidths.
71 |
72 | The new firmware maintains 100% compatibility with the existing serial
73 | command protocol, which means that the updated LTDZ board can be used with
74 | the readily available PC GUI applications, such as WinNWT5, WinNWT4 and
75 | NWT4000lin.
76 |
77 | ## LTDZ Hardware
78 |
79 | LTDZ has two ADF4351 wide-band 35MHz-4400MHz Fractional-N synthesizers.
80 | The first ADF4351 is used as a signal generator, which is also used as a
81 | tracking generator in the scalar network analyzer mode. The second ADF4351 is
82 | used as an local oscillator (LO) for the receiver mixer in spectrum analyzer
83 | and scalar network analyzer modes.
84 |

86 |
87 | [LTDZ PCB and component layout](./hardware/ltdz-pcb.jpg)
88 |
89 | The mixer output is feeding the 120kHz 5th order LC low-pass filter
90 | (120kHz RBW-filter). The output of the RBW-filter is connected to the input
91 | of the AD8307 LOG/RMS-detector. The detected signal level from AD8307 is
92 | then sampled by the STM32F103's 12-bit ADC, and the signal level is sent
93 | to PC application over the on-board USB-to-serial interface.
94 |
95 | It was found out that without any modifications the dynamic range of the LTDZ
96 | 35MHz-4400MHz spectrum analyzer and tracking generator is around 45dB - 50dB.
97 | The linearity of the on-board AD8307 LOG/RMS-detector becomes less accurate as
98 | the signal levels become lower than -40dB (relative to the full scale).
99 |
100 | The receiver bandwidth is fixed to 120kHz by the 5th order receiver bandwidth
101 | LC-filter. As the receiver architecture is direct-conversion zero-IF,
102 | the actual receiver bandwidth is twice the 120kHz ie. 240kHz. This wide
103 | receiver bandwidth makes the device almost useless for making any practical
104 | measurements for RF filters, antenna tuning, spectrum analysis etc.for amateur
105 | radio purposes.
106 |
107 | The relatively high noise floor of the LTDZ hardware design, the wide 120kHz
108 | RBW-filter, and the spurious noise components limit the maximum available
109 | dynamic range of the AD8307 LOG/RMS-detector to 40-50dB. Using digital signal
110 | processing, some of theses limitations can be compensated for better dynamic
111 | range and performance.
112 |

129 | ### RBW-Filter Modifications
130 |
131 | The on-board 120kHz RBW-filter was redesigned to give better low-pass filter
132 | response between 0Hz - 120kHz.
133 |
134 | Fortunately the filter topology did not change, so modifying the component
135 | values is pretty easy to do.

142 |
143 | ### Wiring RBW-Filter Output to ADC Input PA.2
144 |
145 | Added 2 x 12 Kohm biasing resistors to bias the ADC-input to 1.5V-1.6V.
146 |
147 | The other 12 Kohm resistor is connected between the output of the 120 kHz
148 | RBW-filter and the +3.3V linear regulator. The other 12 Kohm resistor is
149 | connected between the output of the 120 kHz RBF-filter and ground.
150 |
151 | Finally, wired the output of the RBW-filter to the ADC input PA.2.

167 | ## Setting Up the Firmware Build Environment
168 |
169 | Project source code, tools and libraries:
170 |
171 | * LTDZ project source code from https://github.com/kalvin2021/ltdz-dsp
172 |
173 | * ARM GCC cross-compiler `gcc-arm-none-eabi`.
174 |
175 | * STM32CubeF1-1.8.3.
176 |
177 | * STM32F10x_StdPeriph_Lib_V3.5.0.
178 |
179 | * ST-Link V2 Programming Utility.
180 |
181 | The build environment is targeted for Linux platforms.
182 |
183 | However, since Windows 10 has now Linux subsystem available, setting up the build
184 | environment for Windows 10 should be quite easy as well.
185 |
186 | ### ARM GCC Cross-Compiler
187 |
188 | This project has been built & tested with the following ARM GCC compiler versions:
189 |
190 | - `gcc-arm-none-eabi-10-2020-q4-major-x86_64-linux.tar.bz2`
191 | - `gcc-arm-none-eabi-6-2017-q2-update-linux.tar.bz2`
192 |
193 | It should be possible to build this project successfully with any other recent
194 | ARM GCC cross-compiler version.
195 |
196 | The ARM GCC cross-compiler package can be downloaded from here:
197 |
198 | https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads
199 |
200 | User may install the downloaded ARM GCC cross-compiler tool-chain into any
201 | suitable directory.
202 |
203 | This documentation assumes that the ARM GCC cross-compiler tool-chain will be
204 | installed into the user's home directory under directory `opt`.
205 |
206 | ```
207 | $ mkdir -p ~/opt
208 | $ cd ~/opt
209 | $ tar xjf ~/Downloads/gcc-arm-none-eabi-_version_-linux.tar.bz2
210 | ```
211 |
212 | Checking the ARM GCC compiler version:
213 |
214 | ```
215 | $ ~/opt/gcc-arm-none-eabi-10-2020-q4-major/bin/arm-none-eabi-gcc --version
216 |

230 |
231 | https://github.com/STMicroelectronics/STM32CubeF1/archive/refs/tags/v1.8.3.zip
232 |
233 | Note: This document and the project's `Makefile` uses the same default installation
234 | location for the zip-package that is used by the official STM32Cube ie.
235 | `~/STM32Cube/Repository/`.
236 | Should the user install the zip-package into some other location, it is required
237 | to update the `BSP_ROOT` in the project's `Makefile`.
238 |
239 | Install the downloaded zip-package into home directory under directory `STM32Cube/Repository/STM32CubeF1-1.8.3`:
240 |
241 | ```
242 | $ mkdir -p ~/STM32Cube/Repository
243 | $ cd ~/STM32Cube/Repository
244 | $ unzip ~/Downloads/STM32CubeF1-1.8.3.zip
245 | ```
246 |
247 | ### STM32F10x_StdPeriph_Lib_V3.5.0
248 |
249 | The STM32F10x_StdPeriph_Lib_V3.5.0 can be found here:
250 |
251 | https://www.st.com/en/embedded-software/stsw-stm32054.html
252 |
253 | Note: This document and the project's `Makefile` uses the same default installation
254 | location for the zip-package that is used by the official STM32Cube ie.
255 | `~/STM32Cube/Repository/`.

263 | $ cd ~/STM32Cube/Repository
264 | $ unzip ~/Downloads/en.stsw-stm32054_v3.5.0.zip
265 | ```
266 |
267 | ### ST-Link V2 Programming Utility
268 |
269 | Updating the firmware will require use of ST-Link V2 USB-dongle and the utility.
270 |
271 | It is important to be aware that some cheap ST-Link V2 clones sold online
272 | may have wrong pin numbering on the USB-dongle's enclosure.
273 |
274 | It is possible to open the enclosure of the USB-dongle, and check the pin names
275 | from the PCB.
276 | Checking the actual pin numbering will reduce the amount of frustration experienced
277 | while trying to get the firmware update completed successfully.
278 |
279 | Use only the following ST-Link V2 signals: GND, SWDIO and SWDCLK.
280 |
281 | **WARNING: DO NOT CONNECT THE +3V3 OR +5V SIGNALS BETWEEN LTDZ AND THE ST-LINK V2 DONGLE!**
282 |
283 | Otherwise you will most probably damage your LTDZ or ST-Link V2 dongle.
284 |
285 | This project has been tested with ST-Link V2 version 1.7.0.
286 | Any other recent ST-Link V2 tool version should work ok.
287 |
288 | For the Windows build environment, a native Windows ST-Link V2 tool needs to be
289 | installed instead of this Linux version of the utility.
290 |
291 | The ST-Link V2 version 1.7.0 for Linux and Windows can be downloaded from the
292 | following link:
293 |
294 | https://github.com/stlink-org/stlink/releases/tag/v1.7.0
295 |
296 | It is also possible to build the tool from the source code.
297 |
298 | ## Building the Firmware
299 |
300 | Clone the LTDZ source code repository into user's home directory under `ltdz-dsp`:
301 |
302 | ```
303 | $ cd ~
304 | $ git clone --depth 1 https://github.com/kalvin2021/ltdz-dsp.git
305 | ```
306 |
307 | Update the firmware source and build the LTDZ firmware for STM32F103:
308 |
309 | ```
310 | $ cd ~/ltdz-dsp
311 | $ git pull
312 | $ export GCC_PATH=${HOME}/opt/gcc-arm-none-eabi-10-2020-q4-major/bin
313 | $ make
314 | ```
315 |
316 | Flash the firmware into the LTDZ board using ST-Link V2:
317 |
318 | ```
319 | $ make flash
320 | ```
321 |
322 | Use only the following ST-Link V2 signals: GND, SWDIO and SWDCLK.
323 |
324 | **WARNING: DO NOT CONNECT THE +3V3 OR +5V SIGNALS BETWEEN LTDZ AND THE ST-LINK V2 DONGLE!**
325 |
326 | Otherwise you will most probably damage your LTDZ or ST-Link V2 dongle.
327 |
328 | ## Using the `ltdz_adc_read.py` Utility
329 |
330 | The `ltdz_adc_read.py` utility can be used for capturing, plotting and saving
331 | the ADC sample buffer data.
332 |
333 | For example, the following will sweep the frequencies from 90MHz to 120MHz with
334 | a frequency step size of 1MHz (using 30 steps).
335 |
336 | ```
337 | $ python3 util/ltdz_adc_read.py -p /dev/ttyUSB0 --start 90m --end 120m --step 1m
338 | ```
339 |
340 | The utility will plot the ADC sample buffer data in time-domain, and compute
341 | the FFT of the samples for each sweep step (using Hanning window).
342 |
343 | The utility will also plot the overall signal spectrum over the frequency sweep range.
344 |
345 | Note: The ADC sample buffer is by default 4096 samples long.
346 | Transferring the complete ADC sample buffer after each frequency step over the USB
347 | serial line with 57600 bits/s will take some time.
348 |
349 | The utility will be used during firmware development for examining the ADC
350 | sample buffer during the frequency sweep.
351 |
352 | The captured ADC sample buffer data can be saved in Matlab/GNU Octave ASCII-format
353 | for later analysis.
354 |
355 | Here is a screen-capture from measuring a FM-band band-reject filter between
356 | frequency range 65MHz - 130MHz (65 steps):

3 | * @file system_stm32f10x.c
4 | * @author MCD Application Team
5 | * @version V3.5.0
6 | * @date 11-March-2011
7 | * @brief CMSIS Cortex-M3 Device Peripheral Access Layer System Source File.
8 | *
9 | * 1. This file provides two functions and one global variable to be called from
10 | * user application:
11 | * - SystemInit(): Setups the system clock (System clock source, PLL Multiplier
12 | * factors, AHB/APBx prescalers and Flash settings).
13 | * This function is called at startup just after reset and
14 | * before branch to main program. This call is made inside
15 | * the "startup_stm32f10x_xx.s" file.
16 | *
17 | * - SystemCoreClock variable: Contains the core clock (HCLK), it can be used
18 | * by the user application to setup the SysTick
19 | * timer or configure other parameters.
20 | *
21 | * - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must
22 | * be called whenever the core clock is changed
23 | * during program execution.
24 | *
25 | * 2. After each device reset the HSI (8 MHz) is used as system clock source.
26 | * Then SystemInit() function is called, in "startup_stm32f10x_xx.s" file, to
27 | * configure the system clock before to branch to main program.
28 | *
29 | * 3. If the system clock source selected by user fails to startup, the SystemInit()
30 | * function will do nothing and HSI still used as system clock source. User can
31 | * add some code to deal with this issue inside the SetSysClock() function.
32 | *
33 | * 4. The default value of HSE crystal is set to 8 MHz (or 25 MHz, depedning on
34 | * the product used), refer to "HSE_VALUE" define in "stm32f10x.h" file.
35 | * When HSE is used as system clock source, directly or through PLL, and you
36 | * are using different crystal you have to adapt the HSE value to your own
37 | * configuration.

273 | * The SystemCoreClock variable contains the core clock (HCLK), it can
274 | * be used by the user application to setup the SysTick timer or configure
275 | * other parameters.
276 | *
277 | * @note Each time the core clock (HCLK) changes, this function must be called
278 | * to update SystemCoreClock variable value. Otherwise, any configuration
279 | * based on this variable will be incorrect.
280 | *
281 | * @note - The system frequency computed by this function is not the real
282 | * frequency in the chip. It is calculated based on the predefined
283 | * constant and the selected clock source:
284 | *
285 | * - If SYSCLK source is HSI, SystemCoreClock will contain the HSI_VALUE(*)
286 | *
287 | * - If SYSCLK source is HSE, SystemCoreClock will contain the HSE_VALUE(**)
288 | *
289 | * - If SYSCLK source is PLL, SystemCoreClock will contain the HSE_VALUE(**)
290 | * or HSI_VALUE(*) multiplied by the PLL factors.
291 | *
292 | * (*) HSI_VALUE is a constant defined in stm32f1xx.h file (default value
293 | * 8 MHz) but the real value may vary depending on the variations
294 | * in voltage and temperature.
295 | *
296 | * (**) HSE_VALUE is a constant defined in stm32f1xx.h file (default value
297 | * 8 MHz or 25 MHz, depedning on the product used), user has to ensure
298 | * that HSE_VALUE is same as the real frequency of the crystal used.
299 | * Otherwise, this function may have wrong result.
300 | *
301 | * - The result of this function could be not correct when using fractional
302 | * value for HSE crystal.
