Trig Out/Calibration
Various kinds of signals can be output from this connector (press
Utility
AuxOutput
to select the desired output type).
1)
TrigOut:
the oscilloscope outputs a signal that can reflect the current
capture rate of the instrument each time a trigger is generated. Connect the
signal to a waveform display device and measure the frequency of the signal;
the measurement result is the same as the current capture rate.
2)
Fast:
the oscilloscope outputs a fast edge signal with 500 ps rise time from
this connector and the signal can be used in the self-calibration of the
oscilloscope.
3)
GND:
the oscilloscope outputs a ground level from this connector.
4)
PassFail:
the oscilloscope outputs a TTL high level when a failed waveform
is detected until the current frame of waveform is finished and then outputs
a low level at the beginning of the next frame of waveform. This signal can
be transmitted to other control system for easy view of the test result.
