H Set the horizontal SCALE to the horizontal scale setting in
Table 4--7 that corresponds to the vertical scale set in substep d.
Press PUSH TO SET 50% as necessary to trigger the signal.
H Read the results at the CHx Pk-Pk readout, which will automatically
measure the amplitude of the test signal. See Figure 4--20.
Set the generator
(reference) frequency to
the test frequency from
Table 4--7.

h. Check against limits:
H CHECK that the Pk-Pk readout on screen is within the limits listed
in Table 4 --7 for the current vertical scale setting.
H Enter voltage on the test record.
H When finished checking, set the horizontal SCALE back to the
50 ns setting.
STOP. Checking each channel’s bandwidth at all vertical scale settings is time
consuming and unnecessary. You may skip checking the remaining vertical scale
settings in Table 4--7 (that is, skip the following substep, i) if this oscilloscope
has performed as follows:
H Passed the 100 mV vertical scale s etting just checked in this
procedure.
H Passed the Verify Internal Adjustment, Self Compensation, and
Diagnostics procedure found under Self Tests, on page 4--5.
