Freehand Probe Holder
The
FreeHand
lets you focus on the oscilloscope
screen instead of on maintaining contact to
multiple test points. It allows the user to
concentrate on what is really important – the
waveform.
It is designed to keep most of the weight on the
probe tip and will prevent lost contact when a
bump to the table shakes the circuit under test.
Additionally, the ZD probe can be mounted
horizontally or vertically in the
FreeHand
, giving
added measurement flexibility.
Probe Calibration Fixture
The PCF-200 probe calibration fixture may be used to
determine the effect of probe input loading on the
circuit under test, for verification of the probe response
to the signal being measured, or as a convenient way
to deskew several probes/oscilloscope channels.
Deskewing with the PCF-200
1.
Connect a fast edge to one or both PCF-200 inputs and terminate the
corresponding output to any oscilloscope channel. Trigger on this
channel for a common time reference.
2.
Connect the probe tip(s) to the appropriate PCF-200 connection point
(solder-in tips may be inserted under the clamping mechanism).
3.
Display the probe signals on the oscilloscope screen and use the
Horizontal adjust controls to align them to a common point.
