The Tektronix DC5009 is a 135 MHz programmable frequency counter plug-in for the TM5000 system. It is internally similar to the DC509 which could be converted to a 5009 through an upgrade kit.
The DC5009 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.
