PCSGU250 upgrades

Instruments PC Oscilloscopes and Recorders

Two questions:

  1. Are the schematics for PCSGU250 available to download?
    2.The oscilloscope is using the AD9288BSTZ40 A/D converter. Assuming that I would replace it with the AD9288BSTZ100 (which has 100MS/s capability), would it be possible to increase the maximum sampling rate and add 50ns/div to the oscilloscope functionality?
    Thank you,
    Darius

  1. Here is the link to download PCSGU250 schematic: box.net/shared/q2zs0l71de

    We can’t guarantee the FPGA can handle and save the ADC data at higher rate as now.

Is the firmware for the FPGA available, so I can program new FPGA with the same firmware?

Sorry, for copyright reasons Velleman never releases sourcecode for the firmware files.
