3.12 Transients recorder
Transient is a term for
short, highly damped
momentary voltage or current
disturbance. A transient recording is recording with the 25 kHz sampling rate. The
principle of measurement is similar to waveform recording, but with a 10 times higher
sampling rate (1024 samples per period). In contrary to inrush or waveform recording,
where recording is triggered based on rms values, trigger in transient recorder is based
on sample value.

Trigger (dV)
Trigger value:
Trigger type
Trigger type set up:
Manual
trigger – user can manually generate a
trigger event.
dV
– voltage rate of change that triggers transients
recorder.
Store buffer
Number of signal periods to be recorded.
Pretrigger buffer
Number of signal periods that user wants to record prior
to the trigger condition occurrence.
Store mode
Store mode setup:
Single
– single transient recording
Continuous
– consecutive transients recording
until user stop or instrument runs out of storage
memory. Every consecutive transients recording
will be treated as a separate record.
