Probe Calibration Fixture
The probe deskew fixture (PCF-200) is provided as a standard accessory with
ZD500, ZD1000, and ZD1500 probes.
The fixture can be used one of two ways:
1. The fixture may be used to determine the effect of probe input loading
on the circuit under test and verification of the probe response to the
signal being measured.
2. The fixture may be used as a convenient way to deskew several
probes/oscilloscope channels. This can be accomplished in the following
ways:
Connect a fast edge to one or both inputs and terminate the
corresponding output to a scope channel. Trigger the scope on this
signal for a common time reference. Connect the probe tip(s) to the
appropriate connection point. Solder-in probe tips and browser tips
may be inserted under the clamping mechanism. Display the probe
signals on the oscilloscope screen and use the channel deskew
adjust to align them to a common point.
Connect the WavePro 7 Zi and Zi-A or WaveMaster 8 Zi and Zi-A fast
edge output to one of the inputs. Set the Zi Series oscilloscope to
trigger on the internal Fast Edge source. Set the trigger delay to
zero. Now, on the vertical dialog, use the Probe Cal - Cable Deskew
button to align one signal/channel at a time to the specified zero
delay trigger point (center of screen). Repeat for as many probes as
you have connected, each time aligning them to the common point.
