Agilent Technologies Portable Generators: Installation and Connections for Agilent Models

Installation - 3

Sense Switch

A local/remote sense switch is provided on each module. Unless you are using remote sensing, make sure that the sense switch is set to LCL (depressed). Remote sensing is used in certain applications to achieve greater accuracy (refer to Remote Sense Connections for more information).

NOTE	If the sense switch is set to remote operation without having sense leads connected to the sense
	inputs, the module will continue to work in the CC mode, but the input will turn off in CV and
	CR modes. Voltage readback will not work in any mode.

Trigger and Digital Connections

A connector is provided on each mainframe for a ground reference of input and output trigger signals (see Figure 3-8). The remote voltage sense, current and voltage monitor signals, analog programming input, fault output pin and a programmable digital output pin are referenced to the trigger input.

	Figure 3-8. Control Connector
TRIG IN	A TTL-compatible input that responds to low-level external trigger signals. A trigger applied to
	this input can be used to change settings (voltage, current, resistance, etc.), toggle between
	settings in transient-toggle mode, or generate a pulse in transient-pulse mode. An external trigger
	affects any module that has its external trigger input enabled by the TRIG:SOUR:EXT command.
TRIG	A TTL-compatible output signal that becomes active (low-level) whenever the electronic load is
OUT	triggered by a GPIB command or TRIG IN signal. This signal can be used to trigger external
	equipment such as oscilloscopes, digitizers, or another electronic load.
TRIG	Provides the common connection for the trigger signals. This common is directly connected to
GND	the chassis.
DIG 1	A programmable digital output line.
DIG 2	A second programmable digital output line.
DIG GND	Provides the common connection for the digital signals. This common is directly connected to
	the chassis.

Consistent with good engineering practice, all leads connected to the connector should be twisted and shielded to maintain the instrument's specified performance.
