5. Carefully focus and check the display. If the waveshape
does not show good transient response because of over­
shoot, ro llo ff or bumpiness, proceed with the adjustments
described in the oscilloscope instruction manual.
Other Checks
The 067-0521-00 can be used as a limited bandpass plug-in
unit. It is useful for inserting calibrated time marks into
the vertical system when adjusting the oscilloscope geometry,
trigger, and time-base circuits for proper operation. For
making a sine-wave bandpass check of an oscilloscope pre­
am plifier system, use a 1 -series or letter-series plug-in unit
rather than the plug-in test unit.
When using the 067-0521-00 to couple an input signal to
the oscilloscope vertical amplifier, the deflection factor of
the unit is about 0.5 volt/cm with the TEST FUNCTION
switch set to LOW LOAD or HIGH LOAD and the VARI­
ABLE control turned fully clockwise. LOW LOAD is the
normal position of the TEST FUNCTION switch for dis­
playing signals applied through the EXT INPUT connector.
Resistance Measurements
Blank columns are provided in Table 4-1 for recording
resistance readings and the meter used. Resistance measure­
ments recorded when the 067-0521-00 operates correctly may
be useful if trouble should occur.
