Function Generators Replace Obsolete Models

With many test racks in service for a long time, test engineers often must replace equipment (or build identical racks) after equipment fails or needs service, but is discontinued by the manufacturer. The investment in software to upgrade to a new model often outweighs the benefits. Hence, Tabor Electronics has made its Models 8550 and 8551 function generators software compatible with the Agilent Technologies (formerly Hewlett-Packard) Models 8112A and 8116A. Because the Tabor models use programming commands identical to the obsolete HP models, you can use them without rewriting application code or instrument drivers. Both models have IEEE 488 communication ports.

The Model 8550 is a function generator, linear-sweep generator, logarithmic-sweep generator, and phase-locked loop (PLL) generator. Waveforms include sine, triangle, symmetrical square, positive and negative square waves, and DC. It has control inputs for FM, VCO, and AM modulation and it can store up to 30 test setups. The Model 8551 adds pulse-output waveforms such as normal pulse, fixed duty-cycle pulse, and pulse complement. Both models have a maximum output frequency of 50 MHz.
