  • Page 6: Introduction

    1 Introduction In this publication, items relevant only to the DM7275-01, DM7275-02, DM7275-03, DM7276-01, DM7276-02, and DM7276-03 are indicated as “the instrument.” If the communication monitoring function is used at the time of program creation, commands and responses will be conveniently displayed on the measurement screen.
  • Page 7 Response Messages  When a query message is received, its syntax is checked and a response message is generated. If an error occurs when a query message is received, no response message is generated for that query. Command Syntax  Command names are chosen to mnemonically represent their function, and can be abbreviated.
  • Page 8 Message Terminators  This instrument recognizes the following message terminators (delimiters). [RS-232C/USB/LAN] • CR • CR+LF [GP-IB] • LF • CR+LF • EOI • LF with EOI Depending on the instrument’s interface settings, the following can be selected as the terminator for response messages.
  • Page 9 Data Formats  The instrument uses character data, decimal numeric data and character string data depending on the command. (1) Character Data Character data always begins with an alphabetic character, and subsequent characters may be either alphabetic or numeric. Character data is not case-sensitive, although response messages from the instrument are only upper case.

  • Page 10: Output Queue And Input Buffer

    Compound Command Header Omission  When several commands having a common header are combined to form a compound command (e.g., :CALCulate:SCALe:PARameterA and :CALCulate:SCALe:PARameterB) if they are written together in sequence, the common portion (here, :CALCulate:SCALe) can be omitted after its initial occurrence. This common portion is called the “current path”...

  • Page 11: Status Byte Register

    Status Byte Register [GP-IB] This instrument implements the status model defined by IEEE 488.2 with regard to the serial poll function using the service request line. The term “event” refers to any occurrence that generates a service request. Standard Event Register Description Service Request Output Queue data information SRQ occurrence...
  • Page 12 Status Byte Register (STB)  During serial polling, the contents of the 8-bit Status Byte Register are sent from the instrument to the controller. When any Status Byte Register bit enabled by the Service Request Enable Register has switched from 0 to 1, the MSS bit becomes 1.

  • Page 14 Standard Event Status Register (SESR)  The Standard Event Status Register is an 8-bit register. If any bit in the Standard Event Status Register is set to 1 (after masking by the Standard Event Status Enable Register), bit 5 (ESB) of the Status Byte Register is set to 1. See: “Standard Event Status Register (SESR) and Standard Event Status Enable Register (SESER)
  • Page 15 Standard Event Status Enable Register (SESER)  Setting any bit of the Standard Event Status Enable Register to 1 enables access to the corresponding bit of the Standard Event Status Register.

  • Page 16 Device-Specific Event Status Registers  This instrument provides two Event Status Registers for controlling events. Each Event Status Register is a 16-bit register. When any bit in one of these Event Status Registers enabled by its corresponding Enable Register is set to 1, the following happens: •...
  • Page 17 Status Query Register Bit 15 CNT_ERR Set to 1 when a contact error occurs. Bit 14 MEM_OVR Set to 1 when the internal measurement memory is full (5000 data). Bit 13 Set to 1 when the BIN measurement result is OUT OF BIN. Bit 12 Set to 1 when the comparator result is upper threshold FAIL.
