TRIGger:PSYN
c:CH<x>:DCRAtio
This command sets or queries the data-to-clock ratio (<nr1>,<nr1>) of the
PatternSync Trigger module for the channel specified (CH<x>), which can be 1
through 8. Th
e channel specified must be from a PatternSync Trigger module. The
first <nr1> value represents the d ata rate and the second <nr1> value represents
the clock rate.
One of the data values in the Data/Clock ratio pair must be a 1.
Valid data
entries range from 1 to 128. A constraint on the valid range i s set by the
Pattern Length and Data Rate settings.
Invalid e
ntries are ignored, leaving the ratio unchanged.
The query form returns the data-to-clock ratio for the specified channel.
If you attempt to modify this parameter while the AUTOSync:DCRAtio is ON,
you will receive Execution Error code 2539 with an error message "Pattern
Sync Pa
rameter is not settable". (See Messages for general information on
programming interface messages.)

Examples
TRIGGER:PSYNC:CH1:DCRATIO 2,1 defines the data-to-clock ratio for channel
1as2:1.
TRIGGER:PSYNC:CH1:DCRATIO? might return
TRIGGER:PSYNC:CH1:DCRATIO 1,2, indicating the current data-to-clock
ratio is 1:2 for channel 1.
TRIGger:PSYNc:CH<x>:PLENgth
This command sets or queries the pattern length (<nr1>) of the PatternSync
Trigger module for the channel specified (CH<x>), which can be 1 through 8. The
channel specified must be from a PatternSync Trigger module. The pattern length
must be in the range available for the channel/module chosen.
The query form returns the pattern length for the specified channel.
If you attempt to modify this parameter while the AUTOSync:PLENgth is ON,
you will receive Execution Error code 2539 with an error message "Pattern
Sync Parameter is not settable". (See Messages for general information on
programming interface messages.)
