DP501
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. 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, or through a dedicated prescaler signal for microprocessor based counters like the DC50(0)9.
