Installing Your LDX-3232 High Compliance Current Source

GPIB Connector

C H A P T E R 1

The IEEE 488 GPIB interface connector is located on the rear panel, directly above the power input module and fuse. See Figure 1.2, LDX-3232 Rear View. Attach the GPIB cable to the 24-pin connector located on the rear panel. The connector is tapered to ensure proper orientation. Using your fingers, tighten the two screws on the cable connector.

A total of 15 devices can be connected together on the same GPIB interface bus. The cables have single male/female connectors on each end so that several cables can be stacked. This allows more than one cable to be attached to any one device. However, the maximum length of the GPIB cables must not exceed 20 meters (65 feet) total or 2 meters (6.5 feet) per device.

The GPIB Address

The talk and listen addresses on the LDX-3232 High Compliance Current Source are identical. This GPIB address is read locally by pressing the (GPIB) LOCAL switch with the address displayed on the LED display. The instrument comes from the factory configured with the GPIB address set to 1. You can change the LDX-3232's GPIB address locally (via front panel). A procedure for changing the address can be found in the section "Changing the GPIB Address" in Chapter 3.

Tilt-Foot Adjustment

The LDX-3232 High Compliance Current Source comes standard with folding front legs and two rear feet for use as a bench top instrument. Extending the front feet so that the instrument front panel sits up makes it easier to view the LED displays. To use them, place the unit on a stable base and rotate the front legs downward until they lock into position.

Operating the LDX-3232 Precision Current Source

Now that the LDX-3232 High Compliance Current Source is installed and ready for use, you can begin to learn about its operation. The following photos show the functional keypad groupings, back panel connectors, and so on. Use these figures to familiarize yourself with the LDX-3232. After that, use Chapter 2 for fundamentals of operating your instrument.
