-8 dB Range Flatness Verification
-8 dB Range Flatness Verification
Checks high frequency AC amplitude flatness on the -8 dB attenuator range. 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.If you are using substitute test equipment, verify that the input imped-
ance is 50 Ω, because load accuracy directly affects measurement quality.
2. Set the precision AC Voltmeter to "Medium, Medium" Digital Filter and Filter Restart.
3. Set the instrument to each output described in the table below and measure the output amplitude with the AC
voltmeter. This will become the reference measurement. Set the output impedance to 50 Ω. Be sure the output is
enabled.

Q 50 Ω Sine 1.200 Vrms 1.000 kHz 1.2 Vrms ±0.0127 Vrms
4. Set the measured value in Step 3 to be the reference value on the AC voltmeter.
5. Set the instrument to each output described in the table below and measure the output amplitude relative to the
source as a percent with the AC voltmeter. Note that the table also lists the output in dB if you are using a power
meter to perform this test.
