Pulse Generator 50 MHz PG508

TM 500 SERIES PRODUCTS

The PG 508 50-MHz Pulse Generator is a high-performance generator featuring high output voltage, delay, variable rise and fall times, 1 megohm trigger input, and gating capability to handle a wide range of logic and other applications. It is ideally suited for MOS and CMOS logic circuit design. Output amplitude is 20V peak-to-peak from a 50Ω source into a high impedance load, or 10V peak-to-peak into a 50Ω load. The low-reactance 50Ω source impedance delivers clean signals at the end of unter-minated cables, eliminating the need to terminate the pulse generator output. Variable rise and fall times from <6 ns over a range of 100:1 remain constant with changes in pulse output amplitude, thereby reducing set-up time.

A front-panel control-error light tells the operator when he has selected illegal modes, or when timing conflicts exist. The PG 508 occupies two compartments in a TM 500 Mainframe allowing space for companion instruments.
