14.Set the DVM to measure AC Volts. Press the following DVM keys so that it reads out in dBm:

50 4STORE5 4

15.Set the EMC analyzer center frequency to 9 kHz and press 4SGL SWP5. Record the DVM readout in column 2 of Table 2-69.

16.Repeat step 15 for all center frequencies listed in Table 2-69

Table 2-69.

17.Subtract the 100 kHz Level Flatness readout in Table 2-68 from the 100 kHz DVM Readout in Table 2-69 and record as the DVM O￿set at 100 kHz.

18.For example, if the Level Flatness reading from Table 2-68 is +1.0 dB and the DVM Readout from Table 2-69 is 015.0 dBm, the DVM o￿set would be +16.0 dB.

(DVM) 0 (Power Meter) = DVM O￿set

19.Add the DVM O￿set from Step 16 to each of the DVM Readouts in Table 2-69 and record as the Corrected Level Flatness in column 3.

For example, if the DVM Readout from Table 2-69 is 015 dBm, and the DVM O￿set is +16.0 dB, the corrected readout would be +1 dBm.

(DVM) + (DVM O￿set) = Corrected Readout
