Clock Recovery Commands
ODRatio
Example 10 OUTPUT 707;":CRECOVERY1:LOCKED?"
ODRatio
Command
(83496A) :CRECovery{1 | 3}:ODRatio <divide_ratio>
This 83496A command sets or queries the output clock divide ratio. This determines the data
rate at the front-panel recovered clock output. The ratio can be set to a value of 1, 2, 4, 8, or
16. Sending this command while the output divider is set to auto (
refer to “ODRatio:AUTO”
on page 9-7 ), results in a settings conflict error.
Restrictions
83496A. Software revision A.04.20 and above.
Example 10 OUTPUT 707; ":CRECOVERY1:ODRATIO 2"
Query :CRECovery{1 | 3}:ODRatio?
Returned Format
[
:CRECovery{1 | 3}:ODRatio] <divide_ratio><NL>
ODRatio:AUTO
Command
(83496A) :CRECovery{1 | 3}:ODRatio:AUTO {{ON | 1} | {OFF | 0}}
This 83496A command enables or disables the module’s capability to automatically set the
divide ratio for the front-panel recovered clock output. With auto on, the instrument auto-
matically selects an output divide ratio setting to 1:1 for frequencies equal to or less than 7.1
GHz or 1:2 for frequencies greater than 7.1 GHz.
Restrictions 83496A. Software revision A.04.20 and above.
Example 10 OUTPUT 707; ":CRECOVERY1:ODRATIO:AUTO ON"
Query :CRECovery{1 | 3}:ODRatio:AUTO?
Returned Format [ :CRECovery{1 | 3}:ODRatio:AUTO] {{ON | 1} | {OFF | 0}}<NL>
RATE
Command
(83491/2/3/4/5/6A) :CRECovery{1 | 3}:RATE {TOData | R155 | R622 | R1062 | R1250 | R2125 | R2488 | R2500 | R2666 | R9953 | R10312
| R10664 | R10709 | RANGE10G}
This command sets the clock recovery module’s data rate. The available rates for each mod-
ule, with associated command arguments, are listed in
Table 9-4 on page 9-8 . Rate parame-
ters are nominal and reflect front-panel labels and not actual data rates. The TOData
argument selects triggering on the data. Although this command will work with 83496A mod-
ules, on new programs for the 83496A module, use the command
“CRATe” on page 9-5 .
Restrictions The CONTinous query response is only returned by 83496A modules and requires software
revision 4.20 and above.
Example 10 OUTPUT 707;":CRECOVERY3:RATE R2488"
Query :CRECovery{1 | 3}:RATE?
Returned Format
The CONTinuous query response appears in queries only and can not be sent in a command
string. CONTinuous is returned whenever the data rate of an 83496A module is not one of the
standard values set using the CRECovery:RATE command. If the CONTinuous argument is
returned, use the CRECovery:CRATE command to query the actual value.
Refer to “CRATe”
on page 9-5 .
