EMI Average Detector Accuracy
23.Change the Pulse Frequency on the IGUU 2916 EMI pulse generator to
100 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 100 Hz
pulse frequency in Table 22-56.
26.Change the Pulse Frequency on the IGUU 2916 EMI pulse generator to
10 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 10 Hz pulse
frequency in Table 22-56.
Band B Testing
1. Set the IGUU 2916 EMI pulse generator to output a 10 MHz Sine Wave
signal.
2. Connect the IGUU 2916 EMI pulse generator Output Sine Wave Generator
to the EMI receiver RF Input.
3. Preset the EMI receiver by pressing Mode Preset.
4. Tune the receiver to 10 MHz with a span of 0 Hz by pressing FREQ
Channel, Center Freq, 10 MHz then SPAN X Scale, Zero Span.
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.
