ETTING STARTED
The GKT-100 deskew fixture is used to compensate for
the propagation delay between a passive voltage probe
and current probe. It is used with the GDS-3000.
Required tools
• GDS-3000 x 1
• GKT-100 x 1
• USB type A-B cable x1 -used for deskew fixture
• Standard passive probe x1
• Current probe x1 (GCP-530 or GCP-1030)

Item Description
1 Connect the USB cable: Connect the USB cable to the
USB port on the deskew fixture and the other end of
the cable to the USB host port on the GDS-3000.
2 Connect the current probe: Connect a current probe
(GCP-530 or GCP-1030) to the loop on the deskew
fixture and the other end of the current probe to the
CH1 terminal on the front panel of the GDS-3000.
3 Connect the passive probe: Connect the passive
probe to the JP2 terminal on the deskew fixture and
the other end to the CH2 terminal on the GDS-3000
front panel.
4 Grounding: Connect the grounding clip of the passive
voltage probe to JP1 terminal on the deskew fixture.
Note • Demagnetize and zero the current probe. Refer
to the current probe’s documentation for
instructions on how to do this.
• Make sure the direction of the arrow on the
current probe and that on the current loop are
pointing in the same direction.
