I recently taught Lady Heather how to calculate real time histograms of the various plots. While characterizing the performance of a UCT-8663 DOCXO installed in a HP-53132A counter (using the Gerry Sweeny board), I enabled the histogram feature and got a nice plot showing the TAPR TICC time interval resolution. The TICC was configured for timestamp mode with chA=counter 10 MHz output to a TADD2-mini divider, chB=5071A 1PPS, TICC clock=5071A 10 MHz. The TICC time interval resolution is clearly visible... the bin peaks are 54.471 ps apart.
