4 Calibration Procedures

0 dB Range Flatness Verification

This procedure checks the high frequency ac amplitude flatness above 100 kHz on
the 0dB attenuator range. (Flatness is relative to 1 kHz.)
1 Connect the power meter to measure the output amplitude of the instrument
2 Set up the function generator as follows:
3 On the power meter, use the Relative Power function to set the current reading
4 Set the power meter offset to equal the 100kHz_0dB_offset value previously

– Waveform: Sine
– Frequency: 100 kHz
– Amplitude: 3.51 dBm
