TVS600 & TVS600A Command Reference
C–5
H When CALC<n>:WMP:GATE is set to OFF, the measurement zone becomes the
entire waveform record. The measurement zone defined by the :GATE
command parameters is ignored.
All measurements included in the CALC block are affected by these commands,
but gating for each CALC block is settable independently.
The CALCulate<n>:WMParameter:EDGE command selects the waveform edge
that the measurement is taken on for these edge-based measurements:
H CROSs, NCROSs, and PCROSs
H DELay
H FTIMe and RTIMe
H COPulse
The CALCulate<n>:WMParameter:SLOPE command selects the polarity of the
edges used in DELay measurements; the polarity of the edge used for the other
edge measurements is determined implicitly (for example, RTIME use positive
slope, etc.).
When CALC:WFM:GATE is set to OFF, the waveform analyzer finds the edge within
the entire waveform record; when set to ON, the waveform analyzer finds the
edge with in the measurement zone.
Measurement Algorithms
The automated measurements are defined and calculated as follows.
