Anritsu Series MS278XB MS2781B Marker Amplitude Deviation, From 30 kHz RBW dB Specifications

Operation Verification Measurements

13.Record the new marker level readout value on the display to the corresponding cell in Table 5-12.

14.Calculate the amplitude deviation by subtracting the new marker value from the 30 kHz RBW marker reading.

15.Verify that the amplitude deviation is < 0.1 dB.

16.Repeat steps 11 through 16 for the rest of RBW and SPAN combinations in Table 5-12.
