2.c. (See Table 12: Analog bandwidth, < 3.5 GHz models on page 228.)
(See Figure 21: Measurement of analog bandwidth on page 230.)
Set the horizontal Scale to the horizontal scale setting that corresponds to
the vertical scale set in substep 2.c. (See Table 12: Analog bandwidth, <
3.5 GHz models on page 228.) Press PUSH-SET 50% as necessary to
trigger the signal.
Adjust the output of the generator until the reading on the power meter is
equal to the reading recorded on the power meter in substep 2.e.
Read the results at the Chx Amplitude mean readout, which will
automatically measure the amplitude of the test signal. Refer to the
following figure.

g. Check against limits:
■
CHECK that the Amplitude mean readout on screen is within the
limits listed in the table for the current vertical scale setting. (See
Table 12: Analog bandwidth, < 3.5 GHz models on page 228.)
■
Enter the voltage on the test record.
■
When finished checking, set the horizontal Scale back to the 20 ns.
h. Check remaining vertical scale settings against limits:
■
Check the remaining vertical scale settings for the channel under test
by repeating substeps 2.c through 2.g for each of the remaining
scale settings for the channel under test.
■
When doing substep 2.f, skip the subparts that turn on the Chx
Amplitude mean measurement until you check a new channel.
■
When selecting a new channel and before doing substep 2.f, touch
the Clear All button to remove the previous channel measurements.
