Tektronix TG 501 Time Mark Generator/Calibrator plug-in for TM 500 systems. Produces time marker signals, generated from a stable oscillator timebase, for scope timebase calibration from 1nsec (1GHz) to 5 sec (0.2Hz) in 1-2-5 sequence. This unit is working and calibrated. To the best of my ability to measure, this TG 501 exceeds all factory specs. At 0.1msec (10kHz), an HP 5335A counter (with GPS-DO referenced OCXO timebase) shows a frequency error of less than 1E-5 (0.00001%) after a two-hour warm up in my TM-503 mainframe. I have verified that the variable timing percent error readout is accurate. I used a Tek 7S12 sampling plugin and S2 sampling head to verify the level amplitude of the 5ns, 2ns and 1ns outputs. Physical condition is typical for these instruments — see the pictures.  Payment by PayPal only. Shipping is by USPS Priority Mail to the lower 48 for a flat rate of $15.00. No cables, manual, or any accessories are included — this auction is for the TG 501 only. A free manual download is available from the BAMA website.
