Excellent video. Thank you! I also have an HP 8591A (your video title is "8491A" but your instrument is the 8591A) that has a problem. I'll let you know if I fix it!
To repair slow updates on an HP 8491A Spectrum Analyzer, first ensure that the device’s firmware is up to date, as outdated firmware can cause performance issues. Next, check all connections and cables for damage or loose connections that may affect data transmission. Regularly clean the internal components to prevent dust buildup from slowing down processing speed. Additionally, perform a self-test or calibration as recommended in the user manual to identify any internal faults. If the problem persists, consider consulting the service manual for more detailed troubleshooting steps or contacting a professional technician for assistance.
Thanks for the video. That overheated chip is a GAL16v8-25QP, so it's unlikely that you'd find a programmed replacement.
