Tektronix TG501

Time Mark Generator
The Tektronix TG501 is a refurbished Time Mark Generator.

If you've performed Oscilloscope calibrations, you're probably already familiar with the popular Tektronix TG501 Time Mark Generator and its accuracy. Designed for use in the TM 500-Series Mainframe (sold separately), the Tektronix TG501 is ideally suitable for oscilloscope calibrations while providing marker outputs from 1 ns to 5 s. Features variable timing output with a front-panel 2 digit LED display, which indicates % of timing error between the normal time interval and a variable interval with graticule or division mark on the display.
