Tests
Quasi-Peak Detector Accuracy
Error = Measured - 60 dBμV - Error (Table 22-30)
21.Put the marker in Delta mode by pressing Marker, Delta.
22.Turn on the continuous peak function by pressing Peak Search, More,
Continuous Peak Search On.
23.Change the Pulse Frequency on the IGUU 2916 EMI pulse generator to 20
Hz.
24.Take a single sweep on the EMI receiver by pressing Restart.
25.Once the sweep on the EMI receiver has completed and the auto peak
value is found record the marker delta amplitude value for the pulse
frequency being measured in Table 22-32.
26.Without changing any other setting on the EMI receiver or the IGUU 2916
EMI pulse generator change the Pulse Frequency on the pulse generator
to the other values in the Table 22-32 (except for 1000 Hz) and repeat step
24 and step 25 for each.
