1) Off: No signal is output. The output level is always high.
2) Go: The Go/No-Go judgment result is output.
The result of judgment made with the template function enabled is output.
High: The measurement frequency is within the set range.
Low: The measurement frequency is outside the set range.
When the template function is not selected, a low level is output.
3) End: Count End output
A low pulse of 1 us ±50 ns is output each time frequency measurement is completed.
4) Lvl: Level Det output
In the burst wave measurement mode, the detection signal in the counter is monitored. In the CW
measurement mode, a high level is output constantly.
5) Int: Internal Count Gate Output
The internal gate signal used for frequency counting is output. A high level is constantly output while
the gate is open.
6) Rest: Restart
A low pulse of 1 us ±50 ns is output when a Restart command is executed.
7) Acq: Acquisition output
A low level is output during counter's acquisition operation. A high level is output during frequency
measurement.
