      Master MACB serial #13 (see https://elog.ph.ed.ac.uk/AIDA/367)
      Master MACB mode 5

      NIM 50MHz -> Phillips 726 NIM-TTL-NIM -> Master MACB - external clock (rear panel)

      Note Fuji Diamond Tool Ltd 1020 NIM-TTL level adaptor (NIM, pink front panel) with signal
      rise and falltimes quoted as <10ns produced poor quality 25/50MHz clock - the Phillips 726
      has significantly faster rise and falltimes and drices a higher amplitude signal to 50R load.

      BNC PB-4 trigger output -> Ortec SCA -> LeCroy 429A (500ns width) -> Master MACB - Correlation DAQ
Accepted Trigger

      BNC PB-4 frequency c. 26Hz

0x2F0EFDF4 - 0x2F0068B4 = 0xE9540 = 955712 * 40ns (assume 25MHz) = 38228480ns = 38.2ms

0x1997D52FF8 - 0x19979ADAF8 = 0x3A5500 = 3822848 * 10ns = 38228480ns = 38.2ms

=> correlation clock frequency = 25MHz
