Tektronix TriMode P7700 Series User Manual

connector of the probe should
first be connected to the
P77BRWSR TDP77BRWSR tip.
The P77BRWSR TDP77BRWSR
tip inputs must then be pressed
into place against the A and B
signal traces on the P77DESKEW
TEK-CDA fixture board edge,
located between the Port1 and
Port2 clamps. Either of the two
sets of A and B signal trace
connection patterns located on
the P77DESKEW TEK-CDA fixture
board edge may be used.
Test setup with the P77C292MM
adapter
Connect the probe to any channel
(1-4) of the oscilloscope
(connection to CH4 is shown). Set
the oscilloscope to display the
connected channel. Connect the
probe to the P77C292MM adapter.
Connect the A cable from the
P77C292MM adapter to the FAST
EDGE???? output connector on
the oscilloscope. Leave the B
cable disconnected for now.
Test procedure
Set the probe Input Mode to A-B.
Adjust the oscilloscope to display
a stable waveform (or press the
Autoset button). The FAST
EDGE???? signal is a 1 kHz
square wave. The amplitude of
the FAST EDGE???? signal is
attenuated by 2X, compared to a
single path termination, due to
the power splitter built into the
P77DESKEW TEK-CDA fixture.
When you see a stable square
waveform, check the amplitude
(use the horizontal cursors). The
attenuated amplitude displayed
for a DPO70000 oscilloscope
FAST EDGE???? signal routed
through the Deskew Fixture
should be about 100 mVpp.
