The pre-filter, which can be looped into the signal path before all other analyses, is
located in front of the
level monitor . Here you can analyze the RMS value, the peak
value or the DC voltage component of the signal to be tested.
Following any additional filtering using one or two filters, detailed analysis is initiated at
the
function level . All the usual analysis tools for measuring linear and non-linear dis-
tortion, interference, etc., can be found here. The analysis in the time domain (wave-
form) as well as the FFT analysis with extreme dynamic response and frequency reso-
lution take place here. Moreover, it is possible to record input signals to the hard disk in
order to analyze them at some point later.
In the Freq/phase level , the measured values for frequency and phase or group
delay can be displayed in a different measurement window parallel to the structure
described above.
The monitor outputs at the rear side of R&S UPP allow an oscilloscope or external cir-
cuits to be connected, can be switched to the input-monitor level or function level and
allow the control of analog or digital input signals as well the different analysis levels
directly at the input.
With the R&S UPP-B2 (digital audio interfaces) option, the digital ancillary data in a
standard configuration, such as channel status data, validity and parity bits, can also
be transmitted.
The results of these different measurement functions can be displayed in various ways
in the
measurement windows . The type of display, the units used, scaling, etc., can
be set differently for each measurement function in the associated panels.
The diagram below shows the function blocks and the analysis levels of the R&S UPP:
Similar to the generator component, the analyzer component is operated in two stages:
