HP 3314A Manual

Model 3314A
C. Connect the 50 Ohm Feedthrough Termination to
the 3314A's Main Output. Connect the 5000 Feed-
through Termination to the 3314A's X3 Output.
D. Connect the oscilloscope’s 1МО input to the
3314A's X3 Output.
E. Set the oscilloscope to display 2 complete cycles
with the peaks of the square wave at the 0% and 100%
graticule lines.
F. Using the oscilloscope's delay function (set the
delayed time per division to .1yS/DIV), measure the rise
and fall time from the 10% to 90% graticule lines. In
both cases, this should be less than 2 divisions
( <200ns).
4-23. RESIDUAL DC OFFSET
This test measures the DC voltage output from the X3
Output with no signal present.
