IQ Signal Master™ MX280005A Vector Signal Analysis Software Help : Basic Operation : Modulation Parameters Tab : Symbol Rate
 
Symbol Rate
Sets the symbol rate of the measured signal.
Resolution
0.1 symbols per second (sps)
Symbol Rate Range
The entire measurement signal must not exceed the analysis bandwidth (SPAN) to perform the measurement correctly. Range of Symbol Rate is shown in Table: Symbol Rate Range.

Span Width
Defines the span width for the symbol rate when Modulation Type is other than 2FSK, 4FSK, H-CPM, or O-QPSK. The span width is not displayed and Capture OSR is displayed.
Range

Span/Sample Rate
This value is used in the measuring instrument. This value is calculated based on the Modulation Type and Symbol Rate and is calculated as follows.
When Modulation Type is not 2FSK/4FSK/H-CPM/O-QPSK is shown in Table: Modulation Type is Not 2FSK/4FSK/H-CPM/O-QPSK.
Modulation Type is Not 2FSK/4FSK/H-CPM/O-QPSK
