Input/Output Strobes
PPS Output * A one-pulse-per-second time synchronization output.
This is a normally high, active low pulse (1 ms ± 50 ns)
where the falling edge is the reference.
Mark Input * An input mark (negative pulse > 55 ns), time tags
output log data to the time of the falling edge of the
mark input pulse.
The electrical specifications of the strobe signals are as follows:
Output Voltage: Standard TTL levels
Sink Current: 64 mA
Source Current: 15 mA
Input Voltage: Standard TTL levels
Current:
≤
5mA
* Additional cable required. Ask your dealer for a Command Descriptions Manual.
