 The purpose of the digital loopback is to correct the phase errors introduced by the ADC and Zmod Scope Controller latency and the gain errors caused by the mismatch between the ADC and the DAC full-scale voltages.  The purpose of the digital loopback is to correct the phase errors introduced by the ADC and Zmod Scope Controller latency and the gain errors caused by the mismatch between the ADC and the DAC full-scale voltages. 
 +
 +Regardless of the Zmod Scope used, the system uses a 40 MS/s sample rate for both the Zmod Scope input and Zmod AWG output.
  
 With this setup the frequency response of the filter can be correctly measured regardless of the gain setting of the Zmod AWG.  With this setup the frequency response of the filter can be correctly measured regardless of the gain setting of the Zmod AWG.
