:TIMebase:SRATe
Command Syntax
:TIMebase:SRATe <rate>
<rate> is a double.
Query Syntax
:TIMebase:SRATe?
Description
Enters the symbol rate used when the timebase units are set to unit interval (:TIMebase:UNITs). The following table shows some standard data rates. For example, for the CPRI 8x standard, you would enter:
:TIMebase:SRATe 4.9152E9
Setting the symbol rate automatically sets the unit-interval range :TIMebase:UIRange and unit-interval delay :TIMebase:UIPosition. To change the timebase scale to seconds instead of symbols, use :TIMebase:UNITs.
