the table must contain at least one frequency that lies within the frequency range
for the band
Reference level
The maximum possible reference level depends on the maximum used conversion loss
value. Thus, the reference level can be adjusted for each range according to the used
conversion loss table or average conversion loss value. If a conversion loss value is
used which exceeds the maximum reference level, the reference level is adjusted to
the maximum value permitted by the firmware.
Automatic Signal Identification
Automatic signal identification allows you to compare the upper and lower band results
of the mixer, thus detecting unwanted mixer products due to conversion.
Note that automatic signal identification is only available for measurements that per-
form frequency sweeps (not in vector signal analysis or the I/Q Analyzer, for instance).
Signal ID function
Two sweeps are performed alternately. Trace 1 shows the trace measured on the
upper side band (USB) of the LO (the test sweep), trace 2 shows the trace measured
on the lower side band (LSB), i.e. the reference sweep.
