If your generator cannot output the required amplitude, determine its maximum output at the Test frequency, and use this for the reference amplitude.
The -3 dB limit can be calculated as: 0.707 × reference amplitude.

c. Set the vertical scale:
For the channel you are testing, set the vertical Scale to the next setting
in the table, starting with the 100 mV setting. (See
bandwidth, < 3.5 GHz models
d. Set thetriggering coupling: From the button bar, touch Trigger, then
select Coupling DC.
e. Display the test signal: Do the following subparts to first display the
reference signal and then the test signal.
■ From the button bar touch Measure; then select the Time tab.
■ Touch the Freq button to measure the frequency of the current
channel.
■ Select the Ampl tab. Touch the Amplitude button.
■ Touch the Statistics button, then touch the Mean button.
■ Touch the X (Close) button.
■ Set the generator output so the Chx Amplitude mean readout equals
the reference amplitude in the table. This corresponds to the vertical
scale set in substep 2.c. (See
3.5 GHz models
■ Record the reading on the power meter.
■ Set the trigger as follows:
Press the front-panel Push-Set 50% as necessary to trigger a stable
display. At full bandwidth, you may also want to make small, manual
adjustments to the trigger level. You can use the Trigger Level knob to
do this.
f. Measure the test signal:
Set the frequency of the generator, as shown on screen to the test
frequency in the table that corresponds to the vertical scale set in substep
