Getting Started

Initial Self-Check Procedure

You may perform the following procedure as an initial self-check of your GB1400 Generator and Analyzer. It is also a useful introduction to the basic features and operation of the GB1400.

The fan openings of the GB1400 needs 2-inches of clearance for proper ventilation.

Procedure

1.Make sure both the Generator and Analyzer are equipped with the proper fuse.

2.Make sure that the Generator and Analyzer rear-panel power switches are ON, and that their front-panel power switches are in the STBY position.

3.Plug both instruments into grounded (three-conductor) AC power outlets.

4.Connect a 50-Ohm SMA cable from the Generator CLOCK output to the Analyzer CLOCK input. If using 75-Ohm option, use &5 OHM SMA/BNC cable.

5.Connect a 50-Ohm SMA cable from the Generator DATA output to the Analyzer DATA input.

6.Connect a 50-Ohm SMA cable from the Analyzer rear panel DATA THRESHOLD output to the Analyzer DATA BAR input (required for single-ended data inputs).

7.Power the Generator while pressing and holding its VIEW ANGLE, MSB 1 and (PATTERN) CLEAR keys simultaneously. Release the key after the message Default Settings appears in the display. Repeat this procedure with the Analyzer. This will force both the Generator and Analyzer to power up using factory default settings.

8.Set up the Generator clock and data outputs using controls in the OUTPUT box as follows:

Set this parameter…
