6.On the EMC analyzer, press 4MKR !5, MARKER ! HIGH , More 1 of 3 ,

More 2 of 3 , and MARKER 1 .

7.Set the synthesizer/level generator AMPTD INCR to 4 dB.

8.On the synthesizer/level generator, press AMPLITUDE, then increment down to step the synthesizer/level generator to the next lowest nominal amplitude listed in Table 2-7.

9.Record the Actual MKR 1 amplitude reading in the performance verication test record as indicated by Table 2-7. The MKR amplitude should be within the limits shown.

10.Repeat steps 8 through 9 for the remaining Synthesizer/Level Generator Nominal Amplitudes listed in Table 2-7.

11.For each Actual MKR 1 reading recorded in Table 2-7, subtract the previous Actual MKR 1 reading. Add 4 dB to the number and record the result as the incremental error in the performance verication test record as indicated by Table 2-7. The incremental error should not exceed 0.4 dB/4 dB.
