+10 dB Range Flatness Verification
This procedure checks the high frequency ac amplitude flatness above 100 kHz on
the +10dB attenuator range. (Flatness is relative to 1 kHz.)
1 Connect the power meter to measure the output amplitude of the instrument
as shown on page 72.
2 Set up the function generator as follows:
– Output impedance: 50 Ω (press and select Output Setup).
–Waveform: Sine
– Frequency: 100 kHz
– Amplitude: 13.00 dBm
Make sure the output is enabled.
3 On the power meter, use the Relative Power function to set the current reading
as the reference value. This will allow you to compare future measurement
results in dB.
4 Set the power meter offset to equal the 100kHz_10dB_offset value previously
calculated. This sets the power meter to directly read the flatness error
specification relative to 1 kHz. 100kHz_10dB_offset is calculated on the
"Amplitude and Flatness Verification Worksheet".
5 Set the instrument to each output described in the table below and measure
the output amplitude with the power meter (the relative measurement in dB).
