Tests
Intermittent, Unsteady, Drifting Disturbances
13.On the signal generator turn the modulation On.
14.Take a single sweep on the EMI receiver by pressing Restart.
15.Once the sweep on the EMI receiver has completed and the auto peak
value is found record the marker amplitude as the Pulsed RF Measured
value for the frequency being measured in Table 22-72.Calculate the Delta
between the Sine Wave and Pulsed RF measurements with the following
formula and enter the value in Table 22-72 for the frequency being
measured.
Delta = Pulsed RF Measured – Sine Wave Measured
16.On the signal generator turn the modulation Off.
17.Changing the frequency on the EMI receiver and the signal generator to
the next value listed in Table 22-72.
18.Change the Pulse Width on the signal generator to the corresponding
value for the Frequency being tested listed in Table 22-72.
19.Repeat steps 11 through 19 for the rest of the frequencies in Table 22-72.
