trigger to CH 1 and positive slope. Set oscilloscope to measure delay between the two
signals.
x.
Adjust A7R1200 (fig. 1) until
oscilloscope indicates a
delay of
120 ns
10 ns at the 50
percent amplitude points between the trigger positive edge and the pulse drive negative
z.
Leave cal/normal switch A9S1061 (fig. 1) in the
down position and
continue with
next adjustment check.
a. Connect OUTPUT to multimeter using 50 Ω feedthrough termination.
b. Press CONTINUE pushbutton to display 5 V * 1 X 1. Multimeter will indicate
between 4.9963 and 5.0038 V dc. If multimeter does not indicate within limits specified,
adjust VAR dial until multimeter indicates within limits specified and as close to the
nominal value as possible.
c. Press CONTINUE pushbutton and repeat technique of b above for settings listed in
table 6. Multimeter will
indicate within
limits specified.
d.
When display indicates CAL DONE,
set cal/normal switch A9S1061 (fig. 1) to the
normal position (up).
e. Remove multimeter connections.
