mode, an I/Q analyzer performs data acquisition, while in MSRT mode, a real-time
measurement is performed to capture data.
In MSRA/MSRT operating mode, only the MSRA/MSRT Master actually captures data;
the data acquisition settings for an Analog Demodulation application channel in MSRA/
MSRT mode configure the analysis interval, not an actual data capture from the input
signal.
In addition, a capture offset can be defined, i.e. an offset from the start of the captured
data to the start of the analysis interval for Analog Demodulation.
The currently used analysis interval (in seconds, related to measurement start) is indi-
cated in the window header for each result display.
Analysis line
A frequent question when analyzing multi-standard signals is how each data channel is
correlated (in time) to others. Thus, an analysis line has been introduced. The analysis
line is a common time marker for all MSRA slave applications. It can be positioned in
any MSRA slave application or the MSRA Master and is then adjusted in all other slave
applications. Thus, you can easily analyze the results at a specific time in the measure-
ment in all slave applications and determine correlations.
If the marked point in time is contained in the analysis interval of the slave application,
the line is indicated in all time-based result displays, such as time, symbol, slot or bit
diagrams. By default, the analysis line is displayed, however, it can be hidden from
view manually. In all result displays, the "AL" label in the window title bar indicates
whether the analysis line lies within the analysis interval or not:
●
orange "AL": the line lies within the interval
●
white "AL": the line lies within the interval, but is not displayed (hidden)
●
no "AL": the line lies outside the interval
