+20 dB Range Flatness Verification

This procedure checks the high frequency ac amplitude flatness above 100 kHz on
the +20dB attenuator range. (Flatness is relative to 1 kHz.)
1 Connect the power meter to measure the output voltage of the instrument as
Most power meters will require an attenuator or special power head to
CAUTION
measure the +20 dB output.
2 Set up the function generator as follows:

– Output impedance: 50 Ω (press
– Waveform: Sine
– Frequency: 100 kHz
– Amplitude: 23.90 dBm
Make sure the output is enabled.
