MSRA basics
Some background knowledge on basic terms and principles used in MSRA operating
mode is provided here for a better understanding of the required configuration settings.
5.1
Configuration
Primary parameters
In MSRA mode, only the MSRA primary performs a data acquisition. Thus, all parame-
ters that determine how the I/Q data is captured from the I/Q channel can only be con-
figured in the "MSRA Primary" tab. In all secondary application tabs, these settings are
deactivated (or have a different meaning).
Typical primary parameters include:
●
Sample rate
●
Record length
●
Bandwidth
●
Center frequency
●
Reference level
●
Trigger settings
●
External reference
●
Impedance, preamplification, attenuation
Channel-specific parameters
Each secondary application, however, can define all parameters concerning analysis
individually.
Typical channel-specific parameters include:
●
Center frequency, duration and number of trace points for the secondary applica-
tion data extract
●
Offset of the secondary application data extract from the trigger event
●
Evaluation methods
●
Range and scaling
●
Trace mode
●
Marker positions
Conflicting parameters
Primary and channel-specific parameters can be configured independantly of one
another, in any order that is convenient to you. However, there are dependencies
between the parameters, as the secondary applications can only evaluate data that
has been captured by the MSRA primary previously. Thus, configuring parameters is
