Rear Panel Overview

Rear Panel Controls and Connections

AC Power Entry Module

The AC Power Entry Module is located on the lower right side of the rear panel. The
LDT-5900 must be connected to a properly rated AC source in order to operate.

Trigger Input Connector

The TRIGGER IN connector is located to the right of center on the rear panel. The
leading edge input of this signal is used to initiate a programmable temperature
setpoint step. The TRIGGER IN is a BNC input connector and can be driven with
a TTL signal. For more information on trigger functionality, see "Front Panel
Operations" in Chapter 2.

Trigger Output Connector

The TRIGGER OUT connector is located next to the Trigger In connector. This
output indicates if the measurement for the currently selected control mode (e.g.
Temperature) is within the specified setpoint tolerance. This is a TTL signal
generated by the instrument with programmable delay. The signal is low when the
measurement is out of the tolerance window and high when within the tolerance
window. For more details on trigger functionality, see "Front Panel Operations" in
this chapter
