The P77DESKEW probe deskew fixture provides an edge source to time-align (deskew) signals at the inputs of P7700 Series probes. The fixture provides a means to deskew two probes at the same time. The probe and the fixture are powered by one of the USB ports of the oscilloscope; a USB cable (Tektronix part number, 174-6919-xx) is included with the fixture.
For performing the deskew procedure, Tektronix recommends using a DPO/MSO70000C/70000DX series oscilloscope.
