-8 dB Range Flatness Adjustment (Channel 2)
-8 dB Range Flatness Adjustment (Channel 2)
This section applies to channel 2. It checks high frequency AC amplitude flatness on the -8 dB attenuator range. It also
checks flatness for all other ranges excluding the -24 dB and 0 dB attenuator ranges.
1. Connect a precision AC voltmeter to measure the output amplitude as shown below. Connect the BNC cable to the
Wide Band input of the Fluke 5790A.
2. Use the precision AC voltmeter to measure the output amplitude for each setup in the table below.
Nominal Signal
Setup Frequency
93* 1 kHz
94* 100 kHz
95* 1 MHz
96* 5 MHz
97* 10 MHz
98* 20 MHz
99* 25 MHz
100* 30 MHz
* Constants are stored after completing this setup.
3. Using the numeric keypad or knob, adjust the displayed voltage at each setup to match the measured voltage.
Select ENTER VALUE.
4. After performing setup 100, you have now completed the recommended adjustment procedures. Verification of
the output specifications is recommended.
a. If your calibration procedures require you to verify the adjustment just made, exit the calibration menu and
