Do Not Remove Instrument Covers

To avoid a shock hazard and to maintain proper air flow, never operate the GB1400 with any of its outside covers removed.

Static Sensitive Device Notice

GB1400 outputs use a GaAs FET design and therefore are susceptible to damage from externally applied over-voltage or electrostatic discharge. Never apply reverse voltage to DATA or CLOCK outputs or voltages that are outside the range specified in Appendix A of this manual. Operate the instrument only in a static-controlled environment.

SMA Connectors

Be careful when attaching test cables to SMA connectors. Always tighten the nut on the SMA connector rather than the cable itself. Never tighten an SMA connector nut using more than 10 lb.-in. of torque.

Behavior of Outputs - Turning Power On or Off

When the GB1400 Generator is powered or de-powered its DATA and CLOCK outputs may saturate to their specified positive or negative rail, that is +2 V or - 2 V, for up to 400 milliseconds. If this condition could be harmful to your equipment, then remove all connections to your GB1400 Generator CLOCK and DATA outputs before powering or de-powering the instrument.

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 and top-mounted ventilation slots 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.
