VOLTCRAFT PLUS DSO 4022 - Using the Probe Compensation Signal

39
Using the probe compensation signal
Background
This section introduces how to use
the probe compensation signal for
general usage, in case the DUT
signal is not available or to get a
second signal for comparison. For
probe compensation details, see
page91.
Note that the frequency accuracy and duty factor
are not guaranteed. Therefore the signal should
not be used for reference purpose.
Waveform type
Square waveform used for probe
compensation. 1k ~ 100kHz, 5% ~
95%.
Demonstration signal for showing
the effects of peak detection. See
page49 for peak detection mode
details.
