Multi-standard analysis
Secondary application data
The secondary applications receive data for analysis from the capture buffer, if neces-
sary resampled or with filters applied. The secondary applications can define their own
center frequency, sample rate and record length for their
secondary application data
,
which is an
extract of the capture buffer data
. The secondary applications may not
request more sample points than the captured data contains, or samples from a fre-
quency outside the range of the capture buffer, for example.
Generally, if a signal contains data channels for multiple standards, the individual sec-
ondary applications are used to analyze the channel for the corresponding standard.
Thus, it is of interest to know which secondary application, or more precisely: which
data channel is analyzing which part of the captured data and how each data channel
is correlated (in time) to others.
The MSRA primary display indicates the data covered 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.

Analysis interval
Each secondary application receives an extract of the data from the capture buffer.
However, the individual evaluation methods of the secondary application need not ana-
lyze the complete data range. Some secondary applications allow you to select a spe-
cific part of the data for analysis, e.g. an individual frame, burst or pulse, or to use an
