Trigger Connector

A four-pin connector block (TB201) connector and a quick-disconnect mating plug (RTB2) are provided for input and output trigger signals (see Figure 3-10).

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

Figure 3-10. Trigger Connector

TRIG IN (pin 1) 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.

TRIG OUT (pin 2) A TTL-compatible output signal that becomes active (low level) whenever the load is triggered with a GPIB command or TRIG IN signal. This signal can be used to trigger external equipment such as oscilloscopes, digitizers, or another load.

CommonProvides the common connection for the trigger signals.

Sense Switch

Unless you are using remote sensing, make sure that the sense switch is set to Local. 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 unit will continue to work in CC mode, but the input will turn off in CV and CR mode. Voltage readback will not work in any mode.
