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 92.
2 Use the DMM to measure the output voltage for each of the setups in the table
below.
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 71.
