Trace/Detector
it shows an “f” (for “math function”). It is not always possible to have a unique detector for each trace,
but the test set hardware provides the maximum flexibility of detector selection in order to maintain the
highest accuracy. The letters used for this readout are:
N = Normal
A = Average
P = peak
p = negative peak
S = Sample
Q = Quasi Peak
E = EMI Average
R = RMS Average
f = math function
If the DET letter is green it means the detector is in Auto; if it is white it means the detector has been
manually selected.
Trace Annotation
When Trace Annotation (see View/Display menu) 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.
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 = Log Difference
