h. Check against limits:
H CHECK that the Pk-Pk readout on the screen is within the limits
listed in Table 2--3 for the current vertical scale setting.
H Enter the voltage in the test record.
H When finished checking, set the horizontal SCALE back to the
40 ns (50 ns for TDS5054BE) setting.
STOP. Checking the bandwidth of each channel at all vertical scale settings is
time consuming and unnecessary. You can skip checking the remaining vertical
scale settings in Table 2--3 (that is, skip the following substep, i) if this oscillo-
scope has performed as follows:
H Passed the 100 mV vertical scale setting just checked in this
procedure.
H Passed the Verify Internal Adjustment, Self Compensation, and
Diagnostics procedure found under Self Tests on page 2--5.
NOTE. Passing the Signal Path Compensation confirms the signal path for all
vertical scale settings for all channels. Passing the Internal Diagnostics ensures
that the factory-set adjustment constants that control the bandwidth for each
vertical scale setting have not changed.
