:CHANnel:SIRC:FRATe
Command Syntax
:CHANnelN:SIRC:FRATe <filter rate>
<filter rate> is a double.
Where N identifies a specific channel and must be selected from {1:8}{A|B|C|D}. For example, CHANnel3C.
Query Syntax
:CHANnelN:SIRC:FRATe?
Description
SIRC data is created for specific filter rates and 3 dB bandwidths. Once the SIRC data has been loaded, use this command to select the filter rate or use the :CHANnel{N}:SIRC:FBANdwidth command to select the 3 dB bandwidth. Use the :CHANnel{N}:SIRC:DSTore command to load the SIRC data for the module.
Requires an 86105C, 86105D, 86115D, or 86116C module with Option IRC.
Do not use this command when making TDECQ or TDEC measurements. Because TDECQ and TDEC measurements call for a different bandwidth than the traditional bandwidths used by NRZ receiver mask testing, select the channel bandwidth using the :CHANnel:FSELect:BANDwidth and :CHANnel:SIRC:FBANdwidth commands, rather than the corresponding :CHANnel:FSELect:RATe and :CHANnel:SIRC:FRATe commands. When using the TDEC and TDECQ filters, the value returned by the :CHANnel:FSELect:RATe? and :CHANnel:SIRC:FRATe? queries will not correspond to the symbol rate.
Pattern lock must be turned on (:TRIGger:PLOCk) before you can apply SIRC data.
