These instrument drivers provide a high-level programming interface to your Keysight Technologies instrument. VXIplug&play instrument drivers are an alternative to programming your instrument with SCPI command strings. Because the instrument driver's function calls work together on top of the VISA I/O library, a single instrument driver can be used with multiple application environments.

    Introduction to Programming - 2 SCPI Command Completion SCPI commands sent to the dc source are processed either sequentially or in parallel. Sequential commands finish execution before a subsequent command begins. Parallel commands allow other commands to begin executing while the parallel command is still executing. Commands that affect trigger actions are among the parallel commands.

  • Page 76 TRIGger:SEQuence2:COUNt:CURRent TRIGger:ACQuire:COUNt:CURRent Keysight 66312A, 66332A Only This command sets up a successive number of triggers for measuring current data. With this command, the trigger system needs to be initialized only once at the start of the acquisition period. After each completed measurement, the instrument waits for the next valid trigger condition to start another measurement.
  • Page 77 TRIGger:SEQuence2:HYSTeresis:CURRent TRIGger:ACQuire:HYSTeresis:CURRent Keysight 66312A, 66332A Only This command defines a band around the trigger level through which the signal must pass before an internal measurement can occur. The band limit above and below the trigger level is one half of the hysteresis value added to or subtracted from the trigger level.
  • Page 78 Language Dictionary - 4 Keysight 66312A, 66332A Only This command sets the trigger level for internally triggered current measurements. A positive current trigger occurs when the current level changes from a value less than the lower hysteresis band limit to a value greater than the upper hysteresis band limit.
  • Page 79 4 - Language Dictionary TRIGger:SEQuence2:SLOPe:CURRent TRIGger:ACQuire:SLOPe:CURRent Keysight 66312A, 66332A Only This command sets the slope of an internally triggered current measurement. triggering occurs on the rising edge. POSitive triggering occurs on the falling edge. NEGative EITHer triggering occurs on either edge.
  • Page 80 TRIGger:SEQuence1:DEFine TRIGger:SEQuence2:DEFine TRIGger:SEQuence2:DEFine applies to Keysight 66312A, 66332A Only These commands define the names that are aliased to trigger sequences 1 and 2. The command accepts only ACQuire for sequence 2 and TRANsient for sequence 1 as predefined names. The query allows the user to query the instrument names aliased to sequences 1 and 2.

  • Page 84 Compatibility Language Introduction The Keysight power supplies covered by this manual are programmatically compatible with the HP/Keysight 6632A, 6633A, and 6634A dc power supplies. This means that by using COMPatibility language mode you can program these newer dc sources over the GPIB using COMPatibility commands. To switch from SCPI commands to COMPatibility commands (and vice versa), use the SYST:LANG command, as documented in chapter 4.

This command reads the contents of the accumulated status STAT:OPER? register, which stores any bit condition entered in the status STAT:QUES? register since the accumulated status register was last read, *ESE? regardless of whether the condition still exists.

  • Page 90 Error Messages Error Number List This appendix gives the error numbers and descriptions that are returned by the dc source. Error numbers are returned in two ways:  Error numbers are displayed on the front panel  Error numbers and messages are read back with the SYSTem:ERRor? query. SYSTem:ERRor? returns the error number into a variable and returns two parameters: an NR1 and a string.

  • Page 95 D - Example Programs Your application program will not include the dc source's symbolic name and GPIB address. These must be specified during configuration (when you run IBCONF.EXE). Note that the primary address range is from 0 to 30 but any secondary address must be specified in the address range of 96 to 126.
