Command Syntax
:CRECovery{1:8}:ODRatio {SUB32 | SUB16 | SUB8 | SUB4 | SUB2 | UNITy | SUPer2 | SUPer4 | SUPer8}
Where the {1:8} specifier identifies a slot number which is associated with clock recovery module. On 86108A modules, specify slot 1.
Query Syntax
:CRECovery{1:8}:ODRatio?
Description
Sets the output clock divide ratio. This determines the data rate at the front-panel recovered clock output. Available sub-rates vary from 1:1 to 1:32 and super-rates of 2:1, 4:1, and 8:1 depending on the data rate and loop bandwidth settings. Use the :CRECovery:ODRatio:AUTO command to turn on automatic selection of the clock divide ratio.
| Argument | Divide Ratio | Valid for Input Data Rate |
|---|---|---|
| SUPer8 | 8:1 (Supper-Rate) | ≤800 Mb/s |
| SUPer4 | 4:1 (Supper-Rate) | ≤1.0 Gb/s |
| SUPer2 | 2:1 (Supper-Rate) | ≤3.55 Gb/s |
| UNITy | 1:1 (Sub-Rate) | ≤ 7.1 Gb/s |
| SUB2 | 1:2 (Sub-Rate) | all rates |
| SUB4 | 1:4 (Sub-Rate) | ≥900 Mb/s |
| SUB8 | 1:8 (Sub-Rate) | ≥2 Gb/s |
| SUB16 | 1:16 (Sub-Rate) | ≥3.6 Gb/s |
| SUB32 | 1:32 (Sub-Rate) | ≥7.2 Gb/s |
