The Tektronix DP501 is a 1.3 GHz ÷ 16 prescaler plug-in for the TM500 system.
It is specifically designed to interface with the DC503A, DC509, DC5009, DC510 and DC5010 Universal Counter Timers through the TM500 rear interface to make the counter display the correct frequency directly. For the DC503A this is done by routing the counter's reference clock to the DP501, where it is also divided by 16, and fed back to the counter as the new reference. For all other microprocessor based counters like the DC50(0)9 the correct frequency display is achieved by a dedicated prescaler signal.
The DP501 also contains the required logic to interface a TR502 tracking generator for accurate dot marker frequency measurements, effectively replacing a DC508 Option 7 .
