AQT
Defined measurement time, i.e. the duration of data acquisition to the cap-
ture buffer
Rec Length
Defined record length (number of samples to capture)
SRate
Defined sample rate for data acquisition
RBW
(Spectrum evaluation only) Resolution bandwidth calculated from the
sample rate and record length
In addition, the channel bar also displays information on instrument settings that affect
the measurement results even though this is not immediately apparent from the display
of the measured values (e.g. transducer or trigger settings). This information is dis-
played only when applicable for the current measurement. For details see the
R&S
FSWP Getting Started manual.
Data coverage for each active secondary application
Each secondary application obtains an extract of the data captured by the MSRA pri-
mary (see also
Chapter 5.3, "Multi-standard analysis"
on page 27). Generally, if a sig-
nal contains data channels for multiple standards, the individual secondary applications
are used to analyze the channel for the corresponding standard. Thus, it is of interest
to know which secondary application is analyzing which part of the captured data, or
more precisely, which data channel. The MSRA Primary display indicates the data cov-
ered by each secondary application, restricted to the channel bandwidth used by the
corresponding standard, by vertical blue lines labeled with the secondary application
name. For secondary applications that support several standards (e.g. VSA, LTE) an
estimated or user-defined bandwidth is indicated.
2.2.3
MSRA secondary applications
The data captured by the MSRA primary measurement (or only parts of it) can be eval-
uated by various secondary applications. The measurement channel for each secon-
dary application contains the settings and results for the secondary application data
extract from the capture buffer.
The following figure shows the screen elements specific to the MSRA secondary appli-
cation tabs.
