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.

Status LED Values
Status LED Color | Description |
|---|---|
Amber | The generator is powered and the output at the BNC cable is not enabled. This is the default status at power-on |
Green | The generator is powered and the output at the BNC cable is enabled |
Red | A fault condition may have occurred. Disconnect and reconnect the generator to clear the fault condition |
Recommended Output Mode
Probe*1 | Operation | TEK-DPG Output Mode*2 | 067-1686-xx Input Port |
|---|---|---|---|
The recommended output mode is determined by the combination of oscilloscope model, voltage probe, and current probe, according to the following table. See the user instructions for the Power Measurement Deskew Fixture, Tektronix part number 067-1686-xx, for deskew fixture operation. | |||

High-voltage Probes | |||
P5200, P5205, P5210 P6135A | Compensate timing with respect to current probes | DPO3000: Mode 2 or 4*3 DPO/MSO4000 : Mode 1 or 4*3 | A or B, depending on current probe type |
Small Current Probes | |||
TCP0030 TCP202, TCP312, TCP305 A6302, A6312 | Compensate timing with respect to voltage probes | DPO3000: Mode 2 or 4*3 DPO/MSO4000: Mode 1 or 4*3 | A |
Large Current Probes | |||
TCP0150 TCP303 A6303 | Compensate timing with respect to voltage probes | DPO3000: Mode 4 DPO/MSO4000: Mode 4 | B |
*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.
