Tests
Quasi-Peak Detector Accuracy
Error = Measured - (Power Meter + 106.99)
13.Set the EMI receiver input attenuator to 20 dB by pressing AMPTD Y Scale,
Attenuation, 20 dB.
14.Setup the IGUU 2916 EMI pulse generator as follows:
a. Main Generator: Band A
b. Pulse Frequency: 25 Hz
c. Amplitude: 60 dBμV
15.Connect the IGUU 2916 EMI pulse generator Output Main Generator Band
A/B to the EMI receiver RF Input.
16.Put the EMI receiver in single sweep operation by pressing Single.
17.Take a single sweep on the EMI receiver by pressing Restart.
18.Once the sweep has completed find the peak of the detector output by
pressing Peak Search.
19.Record the marker value in Table 22-28 as the Measured value for the
Band A reference PRF.
20.Calculate the Error with the following formula and enter the value in Table
22-28.
Error = Measured - 60 dBμV - Error (Table 22-27)
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
100 Hz.
