Tests
EMI Average Detector Accuracy
Error = Measured – 40 dBµV + 18.95 dB - Error ( Table 22-50 )
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
1000 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 1000 Hz
pulse frequency Table 22-52 .
26. Change the Pulse Frequency on the IGUU 2916 EMI pulse generator to
100 Hz .
27. Take a single sweep on the EMI receiver by pressing Restart .
28. Once the sweep on the EMI receiver has completed and the auto peak
value is found record the marker delta amplitude value for the 100 Hz
pulse frequency in Table 22-52 .
Band C Testing
1. Set the IGUU 2916 EMI pulse generator to output a 100 MHz Sine Wave
signal.
2. Connect the IGUU 2916 EMI pulse generator Output Sine Wave Generator
to the EMI receiver RF Input.
