Transient

Transients are short, unexpected signals in the distribution network which occur only
once and have high amplitude and high slew rate. They contain high frequency
components. This is why the input signal has to pass a 1.5 kHz high-pass filter before it is
fed into the trigger logic. If the voltage step is higher than the preset value Vp, a
recording of transients, rms, and/or Oscilloscope values is triggered, depending on the
actual settings.
The trigger is operational for the channels CH 1 - CH 4 for voltages, provided that the
transient option is mounted in the instrument.
The transient option allows for sampling frequencies between 100 kHz and 10 MHz.
Note
When using voltage transformers, the scaling as defined in the Hardware
Settings is taken into account.
