Trace Annotation
When Trace Annotation (see Display) is ON, each non-blanked trace is labeled on the
trace with the detector used to take it, unless a Trace Math function is on for that
trace, in which case it is labeled with the "Math Function" on page 1745.
The detector labels are:
NORM
Normal
PEAK
Peak
SAMP
Sample
NPEAK
Negative Peak
RMS
Average detector with Power Average (RMS)
LG AVG
Average detector with Log-Pwr Average
VAVG
Average detector with Voltage Average
QPEAK
Quasi Peak
EMI AVG
EMI Average
RMS AVG
RMS Average
The trace math labels are:
PDIF
Power Difference
PSUM
Power Sum
LOFF
Log Offset
LDIF
