EMI Average Detector Accuracy
Error = Measured – (Power Meter + 106.99)
13.Setup the IGUU 2916 EMI pulse generator as follows:
a. Aux. Generator: Band A
b. Pulse Frequency: 25 Hz
c. Amplitude: 40 dBµV
14.Connect the IGUU 2916 EMI pulse generator Output Auxiliary Generator
Band A/B/C/D to the EMI receiver RF Input.
15.Set the EMI receiver input attenuator to 6 dB by pressing AMPTD Y Scale,
Attenuation, 6 dB.
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 22-48 as the Measured value for the
Band A reference PRF.
20.Calculate the Error with the following formula and enter the value in Table
22-48.
Error = Measured – 40 dBµV + 12.36 dB - Error (Table 22-47)
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.
