13. Set the EMI receiver input attenuator to 10 dB by pressing AMPTD Y Scale,
Attenuation, 10 dB .
14. Setup the IGUU 2916 EMI pulse generator as follows:
a. Aux. Generator: Band A
b. Pulse Frequency: 190 Hz
c. Amplitude: 40 dBµV
15. Connect the IGUU 2916 EMI pulse generator Output Auxiliary Generator
Band A/B/C/D to the EMI receiver RF Input.
16. Put the EMI receiver in single sweep operation by pressing Single .
17. Turn on the continuous peak function by pressing Peak Search, More,
Continuous Peak Search On .
18. Take a single sweep on the EMI receiver by pressing Restart .
19. Once the sweep on the EMI receiver has completed and the auto peak
value is found record the marker amplitude as the Measured value for the
pulse frequency being measured in Table 22-40 .
20. Without changing any other setting on the EMI receiver or the IGUU 2916
EMI pulse generator change the Pulse Frequency on the pulse generator
and the Sweeptime of the EMI receiver to the other values listed in Table
22-40 and repeat steps 18 and 19 for each.
