46. Residual Responses, HP 8593EM, HP 8595EM, and HP 8596EM

Procedure

150 kHz to 1 MHz

1.Connect the termination to the EMC analyzer input as shown in Figure 2-68.

2.Press 4PRESET5 on the EMC analyzer, then wait for the preset routine to ￿nish. Press the following EMC analyzer keys:

3.Press 4SGL SWP5 and wait for a new sweep to ￿nish. Look for any residual responses at or above the display line.

If a residual is suspected, press 4SGL SWP5 again. A residual response will persist on successive sweeps, but a noise peak will not. Note the frequency and amplitude of any residual responses above the display line and to the right of the marker in Table 2-59.
