Low Frequency Flatness Adjustment

Low Frequency Flatness Adjustment
The Low Frequency Flatness adjustment calculates the flatness response
of 3 attenuator paths with the Elliptical filter and 2 attenuator paths
with the Linear Phase filter.
1 Set the DMM to measure Vrms. Make the connections shown on page 81.
2 Use the DMM to measure the output voltage for each of the setups in the
table below.
Nominal Signal
Setup Frequency
29* 1 kHz
30* 100 kHz
31* 1 kHz
32* 100 kHz
33* 1 kHz
34* 100 kHz
35* 1 kHz
36* 100 kHz
37* 1 kHz
38* 100 kHz
* 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 38:
a. If your calibration procedures require you to verify the adjustment
just made, exit the calibration menu and perform "Low Frequency
Flatness Verification", on page 64.
b. If you are making all the adjustments and then verifying the
instrument's performance, continue with the next procedure in
this chapter.
