Oscilloscope Reference Measurement errors
Measurement errors
The following measurement errors can be generated by the instrument. They may be generated in
various situations such as those described below. In general, measurements producing an error will
produce noth
ing.
Error Description
Unstable
Measuremen
tsystemerror
These are generic error m essages that occur when the measurement system was
unable to obtain a correct m easurement
Zero period
No period found
No period 2nd waveform
These occur when the measurement system was unable to correctly measure the
period of a
waveform
Low signal amplitude
Low amplitude 2nd wfm
These occur when the measurement system was unable to correctly measure the
signal amplitude of a waveform
Invalid
gate
This error can occur if measurement gating was turned on and gated a measurement
to a region that was insufficient to complete a measurement
Waveform does not close ref
No second ref crossing
No ref cross 2nd wfm
No backwards ref cross
Wfm does not cross Ref
No ref cross 2nd wfm
No ref cros 1st wfm
These errors can occur when the measurement system cannot correctly find edge
crossi
ngs for the specified edge crossing and waveform
Constant waveform This can be generated from various timing based measurements on flat waveforms
No valid edge This can occur w hen the measurement package was unable to extract a valid edge
crossing in some timing measurements
