    Hi @Rohan16 If you referring to the SPI mode with '0th clock pulse' ? This can be adjusted with Polarity and Phase options.

    Hi @StefKay It looks like dual mode with reference clock is not supported with EclypseZ7. I will try to add support for this next week.

    Hi @rjratnip 1. It could be an adapter/cable contact problem. 2. The AUX supply can only be blocked by the the under/overvoltage 4.11V/5.76V protection circuit. You could have a grounding issue. Are the RPi and 5V supplies floating or grounded ? If both are grounded make sure to use nearby sockets, same splitter. With the default 'USB Power' 'Stop with AUX' the USB supply line is turned off if the AUX voltage is ok, 4.5V...5.5V If this option is 'Always ON' the USB and AUX currents will balance according the voltage/cabling resistance. If the USB voltage is higher than AUX, the AUX current will be lower. Verify the voltage of your supply or use powered HUB.

    Hi @Rohan16 The embedded JavaScript does not support binary number format but the interface does.

    Hi @Marcus Watson Are you using similar vertical range for C2 in WF and script ? The AD3 scope inputs have two input ranges. If C2 with WF app is in low range (high resolution) and with script in high range, the lower resolution could hide details. dwf.FDwfAnalogInChannelRangeSet(hdwf, 1, c_double(5.0)) # C2 low range Approximate overlay looks like this:

    Hi @StefKay T1 = DIO14 = B6

    Hi @GCompton The AD3 bandwidth of 9/30MHz may be too low for such pulse lengths. The device has sampling clock option trigger IOs but this requires digital level signal. Now I tried to enable a sample on analog trigger event but this with the current 'firmware' has a minimum trigger to sampling delay of 12cycles, 96-120ns The only eventual option I see is capturing more data, with min/max sampling and processing it.

    Hi @tyoung_google I was referring to check your SSD/HDD

    Hi @tyoung_google Verify your disk and try to reinstall WaveForms, including Adept Runtime section. It looks like the files are corrupt. The installer has integrity checking, so if this was corrupt during download or copy, it should prompt an error message and not let to continue.

    Hi @liu The latest version is built for 32 (armhf) and 64bit (arm64) ARM.

    Hi @sintech Yes, the interpreter has to be run after data change, new capture, buffer or tab change change. Only the raw data is saved in background, the processed data is not.

    Hi @Albert Cirera You can use View/Logging to save each measurement separately.

    Hi @Rohan16 Currently you are only sending an 0x0A 8bit command. Enter the words you want to write here, like it is by default prefilled:

    Hi @joshna Probably the V_DS input voltage on the analog input channel is out the range. The analog inputs of AD3 have two input ranges, approximately 5V and 50V pk2pk, and adjustable offset. Set offset or range dwf.FDwfAnalogInChannelOffsetSet(hdwf, #, c_double(2.5)) or dwf.FDwfAnalogInChannelRangeSet(hdwf, #, c_double(50.0))

    Hi @malb Update digilent.adept.runtime https://digilent.com/reference/software/adept/start

    Hi @Rohan16 You can use StaticIO to drive the DIO 0/1. If not Z this has higher priority over the DIO than Patterns and Protocol.

    Hi @Rohan16 Only one interface can run at a time that requires the same device resource.

    Hi @bsaulquin The Impedance Analyzer is not suitable for such measurement. This is intended for low power testing of component, passive filters... The amplifier needs high power reference load. https://sengpielaudio.com/calculator-InputOutputImpedance.htm Here I used an floating external supply and 6.2R power resistor, I had at hand, connected to the output. I measured an output impedance of 0.31 Ohms. Here R1 is without and C2 is with load. For me the THD and noise my be high due to the wiring or this is just a cheap amplifier.

    Hi @Caleb Messerly Download and install armhf.deb packages
