-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.

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 .
