If the System Fails the Verification Test
• Disconnect and reconnect the device that failed the verification. Then measure the
device again.
If the performance verification still fails:
• Continue to measure the rest of the verification devices and printout the results of all
four measurement parameters.
• Print the error terms and examine them for anomalies near the failure frequencies.
Refer to Chapter 11 , “Error Terms.”
• Make another measurement calibration and follow the flow chart in Figure 2-14.
