:TRIGger:DCDRatio:TYPE

Command Syntax

:TRIGger:DCDRatio:TYPE  {INTeger | FRACtional}

Query Syntax

:TRIGger:DCDRatio:TYPE?

Description

Enters the clock ratio for pattern lock. Select either an integer sub rate of the symbol rate (INTeger) or a fraction sub rate of the symbol rate (FRACtional).

INTeger

Enter an integer clock divide ratio using the :TRIGger:DCDRatio command. To apply the ratio, disable autodetection (:TRIGger:DCDRatio:AUTodetect). In some situations, you may need to enter a trigger divide ratio for a trigger that is a divided rate from the data rate. For example, for rates greater then 23.2 Gbs, you must provide a divided trigger. When this setting is selected, the following commands are available:

• :TRIGger:SRATe:AUTodetect (Symbol Rate)
• :TRIGger:DCDRatio:AUTodetect (Clock Divide Ratio)
• :TRIGger:PLENgth:AUTodetect (Pattern Length)
• :MEASure:JITTer:DEFine:SIGNal:AUTodetect (Signal Type for Jitter Mode)

FRACtional

Enter an fractional clock rate using the :TRIGger:CRATe command. Autodetection is not applied so the commands listed above for Integer clock ratios have no effect.
