The Tektronix DC509 is a 135 MHz programmable frequency counter plug-in for the TM500 system.

It is internally similar to the DC5009 to which it could be converted through an upgrade kit.

The DC509 uses reciprocal counting with an internal 100 MHz clock phase-locked to the reference oscillator. An R6504 microprocessor (28-pin variant of a 6502 with 8K addressable memory) performs the calculations.

Opt.01 is an OCXO for improved stability.
