Multiline Acceptor Handshake Device must properly receive remote multiline Control messages. Functions Talker Device must be able to transmit. Listener Device must receive commands and data.
  • Page 35: Device Trigger

    Operation GPIB Operation Device Device Trigger will implement the most recently programmed values whether the Trigger unit is in local or remote control. If the power supply is in local mode, the new values will be implemented when it is switched from local to remote control. Device Trigger is typically used to synchronize the operation of a number of addressed devices.
  • Page 36: Service Request

    Operation GPIB Operation Service Service request is a uniline message asserted by the power supply at power on and Request for fault conditions.

  • Page 37: Command Syntax

    Operation Command Syntax Command Syntax Manual The manual uses these conventions when displaying command information. These Conventions characters are not part of the command but are used to denote parameters used with the command. < > (angle brackets) Angle brackets enclose a parameter. Do not include the angle brackets in the command line you send to the computer.
  • Page 38 Operation Command Syntax • Use commas between parameters in those commands with more than one parameter, and between mnemonic parameters as in the MASK and UNMASK commands. Only one comma is allowed and it may be preceded or followed by any number of spaces.
  • Page 39: Command Strings

    Operation Command Syntax Command If you send more than one command line, separate the commands with a semicolon. Strings The semicolon may be preceded or followed by spaces. Example: ISET 2.0A; VSET 5V ISET 2.0A; VSET 5V Command Terminators indicate the end of a command string and tell the power supply to execute the command.

    Operation Command Summary Command Summary Use these commands to control the operation of the supply. They are listed here in order of function such as PROGRAMMING, QUERY, CALIBRATION, and STATUS commands. See “Command Reference” on page 39 for more detailed information about each command and its use.
  • Page 41 Operation Command Summary Table 3.6 Query Commands Command Description AUXA? Asks for the state of the set value for the AUXA command AUXB? Asks for the state of the set value for the AUXB command CMODE? Asks for the power supply’s calibration mode status. DLY? Asks for the programmable time delay setting before the supply reports fault conditions.
  • Page 42 Operation Command Summary Table 3.7 Calibration Commands Command Description CMODE Places the supply into calibration mode. IDATA Calculates the slope and intercept for current programming. Sets the current output to the high calibration point. Sets the current output to the low calibration point. IRDAT Calculates the slope and intercept for current readback.
  • Page 43: Command Reference

    Operation Command Reference Command Reference Table 3.9 Command Reference Command Description ASTS? Asks for the supply’s accumulated status register. The accumulated status register stores any bit that was entered in the status register since the accumulated status query command (ASTS?) was last used, regardless of whether the condition still exists.
  • Page 44 Operation Command Reference Command Description DLY <seconds> Sets a programmable time delay employed by the supply before reporting fault conditions. The power supply uses the time delay after receiving a new output voltage or current setting via VSET or ISET, or after receiving RST, TRG, or OUT ON commands.
  • Page 45 Operation Command Reference Command Description FOLD? Asks for the supply’s present foldback setting. Response: FOLD <mode> where mode is: 0 (OFF) or 1 (CV or Constant Voltage mode) or 2 (CC or Constant Current mode) HOLD <1/ON>,<0/OFF> Enables or disables voltage/current setting hold mode for the supply. When HOLD ON is specified, hold mode is enabled so that all voltage and current settings which would normally be implemented by the supply are held until a TRG (trigger) command is received.
  • Page 46 Operation Command Reference Command Description IRDAT <Ilo>,<Ihi> Calculates and records the slope and offset for readback voltage using IRLO and IRHI data. Set CMODE ON before using this command. See also the calibration procedures in Section 4. <Ilo> and <Ihi> are in <current> format. IRHI The power supply outputs a current value to an external device connected as part of the calibration procedure and records a current readback value...
  • Page 47 Operation Command Reference Command Description OVCAL Causes the master controller to perform automatic calibration of the supply’s over voltage protection circuitry. Set CMODE ON before using this command. Ensure jumper J65 on the GPIB Interface PCB is connected for remote operation. OVSET <voltage>...
  • Page 48 Operation Command Reference Command Description Implements programmed voltage and current settings which had been in hold mode. The supply operates with previous values until the TRG (trigger) command is sent. UNMASK <mnemonics> Enables you to select the supply operating conditions that you are most interested in monitoring for fault occurrence.
  • Page 49 Operation Command Reference Command Description VMAX <voltage> Sets an upper soft limit on the supply’s programmed output voltage. If the soft limit is exceeded, or if the soft limit value is lower than the present output voltage setting, the supply will ignore the command, turn on the ERR LED, and set the ERR bit in the accumulated status register.
  • Page 50: Accumulated Status, Status, And Fault Registers

    Operation Accumulated Status, Status, and Fault Registers Accumulated Status, Status, and Fault Registers The GPIB option card uses three separate registers which are always active. They are the accumulated status, status, and fault registers. You can use the status commands shown in Table 3.8, “Status Commands” to activate the registers. The bit register has twelve conditions, each assigned a bit weight.
  • Page 51: Error Codes

    Operation Error Codes Error Codes If the ERR flag in the accumulated status or fault registers has been activated, an ERR? query will return an error number which corresponds to an event described in the following table. The ERR? query will also clear the ERR bit in the register. Table 3.11 Error Codes ERROR # ERROR IDENTIFICATION EXPLANATION...
