Commands and Queries 
- ROSc:SOUrce {EXTernal|INTERnal}
- ROSc:SOUrce?
- ROSc:STATE?

Rosc

Bases: SCPICmdRead

The ROSc command tree.

Usage
  • Using the .query() method will send the ROSc? query.
  • Using the .verify(value) method will send the ROSc? query and raise an AssertionError if the returned value does not match value.
Properties
  • .source: The ROSc:SOUrce command.
  • .state: The ROSc:STATE command.

source property 

source: RoscSource

Return the ROSc:SOUrce command.

Description
  • This command sets or queries the selected source for the time base reference oscillator. The reference oscillator locks to this source. Depending on the command argument that you specify, you can use an external reference or use the internal crystal oscillator as the time base reference.
Usage
  • Using the .query() method will send the ROSc:SOUrce? query.
  • Using the .verify(value) method will send the ROSc:SOUrce? query and raise an AssertionError if the returned value does not match value.
  • Using the .write(value) method will send the ROSc:SOUrce value command.
SCPI Syntax 
- ROSc:SOUrce {EXTernal|INTERnal}
- ROSc:SOUrce?
Info
  • INTERnal specifies the internal 10 MHz crystal oscillator as the time base reference.
  • EXTernal specifies the user-supplied external signal as the time base reference.

state property 

state: RoscState

Return the ROSc:STATE command.

Description
  • This query-only command returns whether the time base reference oscillator is locked. This command will return either LOCKED or UNLOCKED.
Usage
  • Using the .query() method will send the ROSc:STATE? query.
  • Using the .verify(value) method will send the ROSc:STATE? query and raise an AssertionError if the returned value does not match value.
SCPI Syntax 
- ROSc:STATE?

RoscSource

Bases: SCPICmdWrite, SCPICmdRead

The ROSc:SOUrce command.

Description
  • This command sets or queries the selected source for the time base reference oscillator. The reference oscillator locks to this source. Depending on the command argument that you specify, you can use an external reference or use the internal crystal oscillator as the time base reference.
Usage
  • Using the .query() method will send the ROSc:SOUrce? query.
  • Using the .verify(value) method will send the ROSc:SOUrce? query and raise an AssertionError if the returned value does not match value.
  • Using the .write(value) method will send the ROSc:SOUrce value command.
SCPI Syntax 
- ROSc:SOUrce {EXTernal|INTERnal}
- ROSc:SOUrce?
Info
  • INTERnal specifies the internal 10 MHz crystal oscillator as the time base reference.
  • EXTernal specifies the user-supplied external signal as the time base reference.

RoscState

Bases: SCPICmdRead

The ROSc:STATE command.

Description
  • This query-only command returns whether the time base reference oscillator is locked. This command will return either LOCKED or UNLOCKED.
Usage
  • Using the .query() method will send the ROSc:STATE? query.
  • Using the .verify(value) method will send the ROSc:STATE? query and raise an AssertionError if the returned value does not match value.
SCPI Syntax 
- ROSc:STATE?
