Description

The GP1665H function generator is a programmable instrument capable of generating predefined sine, square, triangle, sawtooth, and DC waveforms. The firmware is customized for the HP 8165A GPIB command set. Software test procedures using the original HP8165A instrument require no code modification when upgrading to the GP1665H.

 

Applications

Automatic Test Equipment (ATE)
Component Analysis
Communication Signals
Process Control
Sonar

Features

The GP1665H offers phase-lock loop (PLL) for stability and accuracy up to 50MHz as well as precision low-frequency waveform for trigger, gate, and burst modes. A selectable 20%-50%-80% duty cycle up to 20 MHz allows versatility in linear applications using sawtooth and rectangular waveforms.
The GP1665H provides internal storage of up to 10 complete sets of parameters and settings by using its internal non-volatile memory. This allows current settings to be saved in case of power failure.
Additionally, the GP1665H gives users the option of logarithmic sweeps over three decades as well as a VCO mode for sweeps go-ing down to 1 µHz. Trigger and modulation modes are available for applications needing modulated bursts. Trigger modes can be used in conjunction with AM or FM from 1 mHz to 50 MHz.
