ground - Ground Selection

Select which DUT ground signals (GND1, GND2, GND3 and/or GND4) should be connected to the PLT system ground.

This affects power supply to the DUT, DDTPxx logic, DUT interaction over UART or USB, and measurements taken against PLT system ground.

Note

Ground selection is only supported on PLT-300A, not on PLT-200A.

Usage:

- command: ground none|<range>|all

Argument

Description

none

Disconnect all GNDx signals from PLT system ground.

range

DUT ground indices or ranges to connect to PLT system ground; see the range examples below.

all

Connect all GNDx signals to PLT system ground.

A range is a comma-separated list of ground indices (1-4) and/or inclusive index ranges (<low>-<high>). Any GNDx signal not named in range is left disconnected from PLT system ground. Example range values:

  • 1: GND1

  • 1-2,4: GND1 through GND2, and GND4

  • 2,4: GND2 and GND4
