Tektronix 071-0590-00 Controls and Indicators, Power Switches, View Angle and Panel Lock Keys

Functional Overview

Controls and Indicators

All of the controls, indicators, inputs, and outputs found on the Generator or

Analyzer front or rear panels are discussed in the following section.

Power Switches

The ON/OFF power switch is located on the left side of the test instrument below the LCD screen. The power switch switches the 120/240 VAC to the system power supply. When off, a Battery backup circuit powers the non-volatile RAM.

Unit Mounting

The GB1400 is designed to be placed: (1) flat on a level surface, capable of supporting its weight, or (2) angled from the surface with the rotating carrying handle. To change the handle's orientation, press both handle-locking buttons (located at the hubs of the handle), rotate the handle to the desired angle, and release the buttons. The handle will click into a locked position. Assure that the handle is locked before placing the unit on a work surface. A Rack mounting option is available for installation of the unit into a 19" rackmount. The rack height for the GB1400 is 7 inches (four RMU).

Unit Cooling

The rear panel fan openings must be kept clear for proper cooling of the unit. Allow a minimum of two (2) inches of rear panel clearance, and one (1) inch of top clearance, while operating the unit.

View Angle and Panel Lock Keys

The PANEL LOCK and VIEW ANGLE keys are located near the top, left side of the front panel.

∙VIEW ANGLE: Use this key to select the optimum LCD viewing angle.

∙PANEL LOCK: Use this key to "lock" and "unlock" the front panel. While the front panel is locked, all keys that can cause setup changes are disabled. This feature can help prevent accidental loss of data when performing long- term or critical tests.

RESET to Factory Default

To return the Generator or Analyzer to factory default settings, turn the instrument OFF and then re-power it while pressing and holding the VIEW ANGLE, MSB 1, and (PATTERN) CLEAR keys at the same time. Release these keys after the message Default Setup appears in the display.
