TEK-DPG
Deskew Pulse Generator
The TEK-DPG Deskew Pulse Generator
is a signal-generating accessory for Tektronix instruments that feature
the TekVPI™ interface, including DPO3000 Series and DPO/MSO4000 Series
oscilloscopes.
The TEK-DPG generator provides a source signal
to the Power Measurement Deskew Fixture (Tektronix part number 067-1686-xx),
used to deskew popular Tektronix probes. The generator and deskew
fixture allow you to precisely deskew the time differences between
instrument channels of current and voltage probes, necessary when
you are using the probes in power measurement applications.

*1 Note that some probe models listed
do not utilize the TekVPI interface. Probes which use the TekProbe-BNC
interface require the TPA-BNC adapter to connect to a TekVPI oscilloscope.
*2 TEK-DPG is not supported by the DPO7000 Series.
The Probe Calibration output from the DPO7000 Series generates the
appropriate source signal for the Power Measurement Deskew Fixture.
*3 Mode 4 is a universal mode for high attenuation
probes. High-voltage probes and current probes can always use Mode
4.

Recommended Oscilloscopes
- DPO3000 and DPO/MSO4000 Series Oscilloscopes with TekVPI probe interface.
- TEK-DPG is not supported by the DPO7000 Series Oscilloscopes,
as these models provide the appropriate source signal at the Probe
Calibration output on the front-panel BNC connector.
