Page 20: Operation
GPIB INTERFACE OPERATION OPERATION Introduction This section covers GPIB Interface programming, starting with IEEE-488 functions, continuing with an extensive set of device-dependent commands, and, finally, providing error codes, and status and fault register information. GPIB Operation A GPIB interface controller card enables you to control an IEEE-488 bus system via computer, identifying which of its interconnected devices are to send and receive data. -
Page 21: Device Clear
OPERATION GPIB INTERFACE 3.2.2 Device Clear The power supply will implement Device Clear regardless of whether it is in local or remote control. Device Clear is typically used to send all or selected devices to a known state with a single command. The power supply will be set to Initial (Power On) Conditions after Device Clear. -
Page 22: Power On Service Request (Pon Srq)
GPIB INTERFACE OPERATION 3.2.6 Service Request Service request is a uniline message asserted by the power supply at power on and for fault conditions. Six (6) power supply conditions are defined as faults. See Section 3.6 Accumulated Status, Status, and Fault Registers for more information about CV, CC, OV, SD, ERR, and FOLD. -

OPERATION GPIB INTERFACE Command Reference Table 3.5-1 Command Reference Command Description Queries the accumulated status for the supply. The accumulated status ASTS? register stores any bit that was entered in the status register since the accumulated status query command (ASTS?) was last used (if at all), regardless of whether the condition still exists. - Page 28 GPIB INTERFACE OPERATION Table 3.5-1 Command Reference (continued) Command Description FAULT? Queries the fault register for the supply's fault condition status. When a bit is set in the fault register, the rear panel J7 connector Fault Line 4 is also asserted.
- Page 29 OPERATION GPIB INTERFACE Table 3.5-1 Command Reference (continued) Command Description IMAX <current> Sets an upper soft limit on the programmed output current for the supply. If the soft limit is exceeded, or if the soft limit value is lower than the present output current setting, the supply will ignore the command, turn on the ERR LED, and set the ERR bit in the status and serial poll registers.
- Page 30 GPIB INTERFACE OPERATION Table 3.5-1 Command Reference (continued) Command Description OUT <ON/off> Enables or disables voltage/current output for the supply.

- Page 31 OPERATION GPIB INTERFACE Table 3.5-1 Command Reference (continued) 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 those supply's operating conditions that you are most interested in monitoring for fault occurrence.
- Page 32 GPIB INTERFACE OPERATION Table 3.5-1 Command Reference (continued) Command Description VRHI Sets the output current for the power supply to the internally-programmed high calibration voltage readback setting.

Page 33: Accumulated Status, Status, And Fault Registers
OPERATION GPIB INTERFACE Accumulated Status, Status, and Fault Registers The M9B option card for the 60W and 300W power supplies 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 3.4-4 to activate the registers. -
Page 34: Error Codes
GPIB INTERFACE OPERATION 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 Table 3.7-1. The ERR? query will also clear the ERR bit in the register. -
Page 35: Calibration
GPIB INTERFACE CALIBRATION CALIBRATION Introduction The GPIB Interface is calibrated in order to adjust the signal levels on the interface card to correspond to the expected signal levels on the power supply's main assembly. You may need to recalibrate the interface whenever you install a new interface board or replace parts either on the interface board or on the main power supply board, or, if the unit falls out of specification due to component aging drifts. -
