Commands and Queries

- *CLS
- *ESR?
- *STB?
- *WAI

Cls ¶

Bases: SCPICmdWriteNoArguments

The *CLS command.

Description

This command (no query form) clears the following: Event Queue Standard Event Status Register Status Byte Register (except the MAV bit) If the *CLS command immediately follows an , the Output Queue and MAV bit (Status Byte Register bit 4) are also cleared. MAV indicates that information is in the output queue. The device clear (DCL) control message will clear the output queue and thus MAV. *CLS does not clear the output queue or MAV. *CLS can suppress a Service Request that is to be generated by an *OPC. This will happen if a single sequence acquisition operation is still being processed when the *CLS command is executed.

Usage

Using the .write() method will send the *CLS command.

SCPI Syntax

- *CLS

Esr ¶

Bases: SCPICmdRead

The *ESR command.

Description

This query-only command returns the contents of the Standard Event Status Register (SESR). *ESR? also clears the SESR (since reading the SESR clears it). For a more detailed discussion of the use of these registers, see Registers.

Usage

Using the .query() method will send the *ESR? query.
Using the .verify(value) method will send the *ESR? query and raise an AssertionError if the returned value does not match value.

SCPI Syntax

- *ESR?

Stb ¶

Bases: SCPICmdRead

The *STB command.

Description

The *STB? (Read Status Byte) query returns the contents of the Status Byte Register (SBR) using the Master Summary Status (MSS) bit. For more information, refer to Registers.

Usage

Using the .query() method will send the *STB? query.
Using the .verify(value) method will send the *STB? query and raise an AssertionError if the returned value does not match value.

SCPI Syntax

- *STB?

Wai ¶

Bases: SCPICmdWriteNoArguments

The *WAI command.

Description

The *WAI (Wait) command (no query form) prevents the instrument from executing further commands or queries until all pending commands that generate an OPC message are complete. This command allows you to synchronize the operation of the instrument with your application program. For more information, refer to Synchronization Methods.

Usage

Using the .write() method will send the *WAI command.
