Hi Steve, Is it easy to store the peak trace values? If you connect a frequency source to the SAS and doing two sweeps capturing the peaktrace and substract them you have a normalised trace. Then when you connect the DUT in between you have directly the insertionloss/gain of the DUT on the screen. F...

Hi Don, I am using the AD9851DDS boards, but for the AD9850 it is similar. I have tried both the Mega and Uno software. I have reset the pins multiple times. Currently I am running on a UNO with the following pin settings: Clk- 13, UD-9, Data -10, Reset 11. I was confused by the documentation that a...

Hi Steve, In the trackgen section I see that the lowest possible spotfrequency is 0,1 MHz and when I hover the mouse over the spot frequency field I see an increment of 150 kHz using the mousewheel. In SDR UNO when you right click in the frequency display of the RX panel then you may select the freq...

Hi Steve, Coming back on my last post I can tell you with pleasure that the Arduino UNO by which we have done the test with Trackgen has come to live again! Do not ask how this could happen, because I was playing with the USB cable, selecting different com ports, measuring some smd resistors on this...

Hi Steve, After the measurements of the DDS output in my setup (playing with several settings of the SAS s.a. app), I tried to upload something else to my Arduino UNO. But nothing happend. The TX/RX LED did not flash and the IDE gave UPLOAD errors like: avrdude: stk500_getsync() attempt 1 of 10: not...

Hi Steve, With the Arduino IDE I have sent several commands, as described in your s.a. manual, to the Arduino UNO. For example the Reset l After switching On the DDS9851 module, controlled by the Arduino UNO there was a (sinewave)output. After the RESET was received the Arduino let stop the DDS gene...

Hi Steve, Good news, and good news. The 1st good news is that the IDE terminal presented the good news, "Trackgen V1.0" after sending "Version". Well done!!! Then I quitted IDE and launched the SAS s.a. app. The 2nd good news is that after selecting the right Comms port the SQUARE turned GREEN! Exce...

Hi Steve,

It might be worth to give it a try, if it is not too much effort for you to generate a special hex file.
I have selected the Arduino UNO pins as follows:
pin 9 : Update (FQUP)
pin 10: Reset (RST)
pin 11: Data (D7)
pin 13: Clock (W_Clk)

Hi Steve, With the Arduino IDE (serial monitor) the Arduino UNO returned "Trackgen V1.0" immediately after sending "Version". Done with the ArduinoUnoCommsTest sketch and togetheter with the SPR connected now. I had uploaded "DDS_tracking.hex with rhe Xloader and not "DDS_tracking.with_bootloader.he...

Hi Steve, Some additional information. With a still uncoupled, not connected RSP I launched your SAS s.a. app. After clicking OK on the message "No RSP found" then the SAS s.a. app started to run. In the Tracking Generator Control section I selected the right Com port and the red SQUARE turned green...
