    Hi guys!
    Can you tell me what is the sampling rate on the input of SR during a scan?
    And, do you know how to set that 80 kHz sampling rate, and/or switch off anti aliasing filter?

    Thanks in advance.

    Sergiy.

      Not possible. Effective sample/data rate is always 22kHz, the hardware 80kHz is the fixed and "inbetween" samples are not accessible, always used via the input filter -- an additional FIR is actually turned off in the Z/I (AIC5) pass.

      During scanning the SR does adaptive downsampling from the 22kHz (via simple averaging) to match the scan speed.
