PGA460: PGA 460-Q1 GUI 1.0.1.9 crashes

Hi,

when I set the record time length to 65536, the graph mode to ADC and start a data dump, I get the message that an array is not long enough.

    Rainer,

    I can confirm that this error does exist in version 1.0.1.9 of the GUI, but only when using the 8-bit resolution output mode (1sample/us). The 12-bit resolution output mode works up to 65536us. Until the 8-bit error is resolved in the next update, you can only use a maximum record time length of 61440us in the direct data path dump mode, use 12-bit output resolution, or use the 128 byte echo data dump for 65536us evaluation.

    Is this GUI limitation currently hindering your evaluation? What is your objective in extracting 65ms of raw ADC data?

    Hello Akeem,

    yes, 12 bit resolution does the job.

    The reason why I read raw ADC data is that I wanted to examine a false echo at about 8 meters, which was displayed in the data dump.

    Thank you for your help.

    Rainer,

    I will close this thread now now. Glad that Akeem's suggestion solved your issue.
