14. Set the DVM to measure A C V olts . Press the following DVM keys so that it
reads out in dBm:
50 4 STORE 5 4
4 MA TH 5 4
15. Set the EMC analyzer center frequency to 9 kHz and press 4 SGL SWP 5 .
Record the DVM readout in column 2 of T able 2-69.
16. Repeat step 15 for all center frequencies listed in T able 2-69

17. Subtract the 100 kHz Level Flatness readout in T able 2-68 from the 100 kHz
DVM Readout in T able 2-69 and record as the DVM Oset at 100 kHz.

18. F or example , if the Level Flatness reading from T able 2-68 is +1.0 dB and
the DVM Readout from T able 2-69 is 015.0 dBm, the DVM oset would be
+16.0 dB .
(DVM) 0 (P ower Meter) = DVM Oset
19. A dd the DVM Oset from Step 16 to each of the DVM Readouts in
T able 2-69 and record as the Corrected Level Flatness in column 3.
F or example , if the DVM Readout from T able 2-69 is 015 dBm, and the DVM
Oset is +16.0 dB , the corrected readout would be +1 dBm.
(DVM) + (DVM Oset) = Corrected Readout
