Commands and Queries 
- *ESE <NR1>
- *ESE?
- *OPC
- *OPC?
- *RST

Ese

Bases: SCPICmdWrite, SCPICmdRead

The *ESE command.

Description
  • This command sets and queries the bits in the Event Status Enable Register (ESER). The ESER prevents events from being reported to the Status Byte Register (STB). For a more detailed discussion of the use of these registers, see Registers. Note: Setting the DESER and the ESER to the same values allows only those codes to be entered into the Event Queue and summarized on the ESB bit (bit 5) of the Status Byte Register. Use the DESE command to set the DESER.
Usage
  • Using the .query() method will send the *ESE? query.
  • Using the .verify(value) method will send the *ESE? query and raise an AssertionError if the returned value does not match value.
  • Using the .write(value) method will send the *ESE value command.
SCPI Syntax 
- *ESE <NR1>
- *ESE?
Info
  • <NR1> specifies the binary bits of the ESER according to this value, which ranges from 0 through 255. The power-on default for the ESER is 0 if *PSC is 1. If *PSC is 0, the ESER maintains the previous power cycle value through the current power cycle.

Opc

Bases: SCPICmdWriteNoArguments, SCPICmdRead

The *OPC command.

Description
  • This command generates the operation complete message in the Standard Event Status Register (SESR) when all pending commands that generate an OPC message are complete. The *OPC? query places the ASCII character ‘1’ into the output queue when all such OPC commands are complete. The *OPC? response is not available to read until all pending operations finish. For a complete discussion of the use of these registers and the output queue, see Registers and Queues. The *OPC command allows you to synchronize the operation of the instrument with your application program. For more information, see Synchronization Methods. Refer to the Oscilloscope operations that can generate OPC table for a list of commands that generate an OPC message. (See Table 3-3.)
Usage
  • Using the .query() method will send the *OPC? query.
  • Using the .verify(value) method will send the *OPC? query and raise an AssertionError if the returned value does not match value.
  • Using the .write() method will send the *OPC command.

Rst

Bases: SCPICmdWriteNoArguments

The *RST command.

Description
  • This command (no query form) resets the instrument to the factory default settings. This
    command does the following: Recalls the default instrument setup. Clears the current
    *DDT command. Disables aliases (:ALIAS:STATE 0). Disables the user password (for
    the *PUD command). The *RST command does not change the following: The current
    working directory (: FILESystem:CWD command). The state of command headers (: HEADer
    command). The state of keyword and enumeration verbosity (: VERBose command). The Power-on
    Status Clear Flag ( *PSC command). The Event Status Enable Register ( *ESE
    command). The Service Request Enable Register ( *SRE command). The Event Status Enable
    Register ( *ESE command). The Service Request Enable Register ( *SRE command). The
    Device Event Status Enable Register ( DESE command). The user password for protected user
    data (: PASSWord command). The content of protected user data ( *PUD command). The
    enabled state of the socket server (: SOCKETServer:ENAble command). The socket server
    port number (: SOCKETServer:PORT command). The socket server protocol (:
    SOCKETServer:PROTOCol command). The USBTMC port configuration (:
    USBDevice:CONFigure command). The destination reference waveform or file path for the
    CURVe command (: DATa:DESTination command). The source waveform for the : CURVe? or
    WAVFrm? queries (: DATa:SOUrce command). The source waveform for the : CURVe? or :
    WAVFrm? queries (: DATa:SOUrce command). The waveform data encoding for the : CURVe
    command or query or the : WAVFrm? query (: DATa:ENCdg command). The starting point for
    CURVe? queries (: DATa:STARt command). The ending point for : CURVe? queries (: DATa:STOP command). All settings associated the : WFMInpre commands. All user settable settings associated with the WFMOutpre commands. *RST only resets the programmable interface settings, it does not change the user interface settings.
Usage
  • Using the .write() method will send the *RST command.
