RMS Average Detector Accuracy
5. Set the Sweeptime to 1 second by pressing Sweep / Control, 1 s.
6. Set the RF Coupling to DC by pressing Input / Output, RF Input, RF
Coupling DC (instruments with option 544 are always DC coupled so this
step is skipped for them).
7. Set the amplitude units to dBµV by pressing AMPTD Y Scale, More, Y Axis
Unit, More, dBµV.
8. Set the reference level to 80 dBµV by pressing AMPTD Y Scale, 80 dBµV.
9. Change the detector used by the EMI receiver to RMS Average by pressing
Trace / Detector, More, Detector, More, RMS Average.
10.Put the EMI receiver in single sweep operation by pressing Single.
11.Take a single sweep on the EMI receiver by pressing Restart.
12.Turn on the marker by pressing Marker.
13.Record the marker value in Table 22-62 as the Measured value for Band B.
14.Calculate the Error with the following formula and enter the value in Table
22-62.
Error = Measured – (Power Meter + 106.99)
15.Setup the IGUU 2916 EMI pulse generator as follows:
a. Aux. Generator: Band B
b. Pulse Frequency: 1000 Hz
c. Amplitude: 40 dBµV
16.Connect the IGUU 2916 EMI pulse generator Output Auxiliary Generator
Band A/B/C/D to the EMI receiver RF Input.
17.Set the EMI receiver input attenuator to 10 dB by pressing AMPTD Y Scale,
Attenuation, 10 dB.
18.Take a single sweep on the EMI receiver by pressing Restart.
19.Once the sweep has completed find the peak of the detector output by
pressing Peak Search.
20.Record the marker value in Table 22-63 as the Measured value for the
Band B reference PRF.
