Has anybody run across native Linus software to run a SainSmart DDS140 USB Scope/FFT I would like to buy one of these scopes/FFTs. As long as the DDS-140 device via USB cable into your compute, it will form a complete oscilloscope test system after running the software. since it included a Raspberry PI, an RF software application, and an Oscope-Spectrum Analyzer.

I made some improvements for the calibration output especially for the 120 (now you can select 100Hz, 1kHz, 10kHz and 50kHz, this is all the sigrok FW delivers). This fixes the issue, the changes could be integrated in your script with an additional command line parameter, e.g. Ok, very good, this explains why it didn't work and the value 0.77 ~ 0.80 = 64/40/2 = 160/100/2 (so maybe 0.80 should go in the script). The 1.60 value must be of course half as big (0.77 looks good), because 6022 has gain=10 and 120 has gain=20 in the two lowest ranges: My correction was to invalidate this structure in case of read errors. As the reading from EEPROM failed the (unpopulated) calibration structure controlsettings.calibrationValues was used. Root cause of #69 was that there was no valid *.conf available so the values from step 2 should be used. If the values from step 1 ( specification->voltage.) are valid they take priority over the values from step 2 ( controlsettings.calibrationValues). On sampling data the calibration values are used to correct offset and gain.On opening the device the EEPROM calibration values are read into controlsettings.calibrationValues, if this fails the message is shown.Also as the DDS120 has own firmware in EEPROM (in this case a so called big EEPROM (capacity > 256 Byte with different 16 bit addressing mode compared to the small Hantek EEPROMs capacity voltageScale and specification.voltageOffset. OpenHantek6022 tries to read calibration data from the EEPROM and as the sigrok firmware for DDS120 does not support EEPROM reading it fails and informs you about this, but this is an info/warning message and not an error.
