"Off" Second Monitor is switched off.
"Input Monitor" Settings and remote commands are the same as for Input Monitor,
see Chapter 5.35, "Input Monitor" , on page 455.
"Level Monitor" Settings and syntax of remote commands are the same as for Level
Monitor, see Chapter 5.36, "Level Monitor" , on page 456. However,
the remote commands use suffix 2. The parameter syntax is OFF |
IRMS | DC | IPEak.
"Function Monitor"
For FFT or Post-FFT measurements, RMS and DC are calculated in
the frequency domain via FFT. Settings and syntax of remote com-
mands are the same as for Level Monitor, see
Chapter 5.36, "Level
Monitor" , on page 456. However, the remote commands use suffix 2.
The parameter syntax is OFF | RMSFft | DCFft | IPEak.
For FFT Mode Overlap or Gapless, two function monitors are availa-
ble. Settings and syntax of remote commands are the same as for
Level Monitor. The two function monitors are controlled separately via
suffix 2 and 6. The parameter syntax is the same except for PEAK
(suffix 2) vs IPEak (suffix 6).

5.38.1 Applications
Every signal that is output by the R&S UPP generator passes through several delay
elements until it returns via the "DUT" to the measurement hardware of the R&S UPP
analyzer. The delay times must be taken into account in order to prevent a new mea-
surement being started – after a signal change – before the new signal becomes visi-
ble on the analyzer. The total measurement time, therefore, is made up of the actual
measurement time and the delay time.
The internal delays of the R&S UPP are known and taken into account automatically
on starting a measurement. The instrument delays are in the range of a few millisec-
