Description
Minimum Requirements and/or Test Equipment
Examples
WaveLink High Bandwidth Differential
Probe
With ground lead and grabber (484010043 and 594200003).
Oscilloscope
WaveMaster, DDA, or SDA 8 Zi / Zi-A model or better.
Probe Deskew Fixture
Part number PCF-200.
50Ω SMA(m) Termination
42402730003 (Mini-Circuits ANNE-50+ or equivalent).
Use the same setup as for the Verification Procedure (on page 62).
1.
Connect the WaveLink High Bandwidth Differential Probe to the oscilloscope input channel.
Make sure the probe is recognized by the oscilloscope and the platform LED channel color
matches.
2.
Connect the Probe Deskew Fixture (part number PCF-200) to the Fast Edge output of the
oscilloscope. Connect the 50Ω termination to the SMA(f) output of the deskew fixture.
3.
Connect the SI Probe tip to the PCF-200 fixture verifying that the positive lead is connected to
the fixture trace, and the other lead is connected to the fixture ground. Connect the ground
lead to the fixture ground (reference the previous figure in the Connecting SI Interconnect
Leads to the Fixture topic for details).
4.
Set the channel on the oscilloscope to:
100 mV/div
0V offset
10 ns/div
Sinx/x averaging 16 sweeps
Measure the amplitude and rise time of the signal
5.
Check that the amplitude is about equal to 350 mV (within 20 mV) and the rise time is less
than 60 ps. The first time you test a probe, you can save the trace to memory for test
comparisons at a later date.
6.
You might also want to save the screen to a file.
