:EMODules:AWGenerator:CLOCk:SMARker:RATio

Command Syntax

:EMODules:AWGenerator{1:8}:CLOCk:SMARker:RATio {SUB4 | 
SUB8 | SUB16 | SUB32 | SUB64}

Where {1:8} identifies slot number which is associated with an AWG instrument.

Query Syntax

:EMODules:AWGenerator{1:8}:CLOCk:SMARker:RATio?

Query Response

{SUB4 | SUB8 | SUB16 | SUB32 | SUB64 | INValid}

Description

For an M8199A/B Arbitrary Waveform Generator (AWG), sets or returns the divide ratio between the AWG's clock on the Sample Marker Out port compared to the AWG's current sample rate. For example, if the sample rate is 200 GHz, and the sample marker ratio is set to SUB4 (1:4 subrate), then the Sample Marker Out port will generate a 50 GHz clock. To return the frequency of the clock at the Sample Marker Out port, use the :EMODules:AWGenerator:CLOCk:SMARker:FREQuency? query.

The command arguments and returned values are:

SUB4

The clock divide ratio is 1:4.

SUB8

The clock divide ratio is 1:8.

SUB16

The clock divide ratio is 1:16.

SUB32

The clock divide ratio is 1:32.

SUB64

The clock divide ratio is 1:64.

INValid

There is no AWG present, or the current AWG doesn't have a Sample Marker Out port.
