(approximately 2.4 days), with
100 μs resolution
• Edge triggered at top of second
and synchronized to PPS
• One-shot, pulse train, or
frequency generator modes with
number of cycles up to 4 million
• Active high or active low pulse
• May be added to MCR1000 and
MCR5000
Masterclock’s MCR-PPO (Programmable Pulse Output) is an
add-in module option for Master Clock Reference devices
which provides a precision time referenced pulse output
synchronized to the PPS of your MCR System.
The PPO option provides a pulse reference based on the high
precision PPS of your Master Clock Reference.
Pulse widths from 100 μs to over 2 days, with resolution of 50
μs, are achievable. You may set your pulse to be active high or
active low, triggered from the top of second. Pulses may be
one shot, or you may use to produce pulse trains or as a
frequency generator.
Each MCR may be ordered with an MCR-PPO module option.
