Series 2200 Programmable DC Power Supplies Reference Manual Section 3: Remote operation Parameter types Many power supply commands require parameters. Parameters are indicated by angle brackets, such as . There are several different types of parameters, as listed in the following table. The parameter type is listed after the parameter. Some parameter types are defined specifically for the arbitrary/ function generator command set and some are defined by SCPI.
Section 3: Remote operation Series 2200 Programmable DC Power Supplies Reference Manual Chaining commands and queries You can chain several commands or queries together into a single message. To create a chained message, first create a command or query, then add a semicolon (;), and finally add more commands or queries and semicolons until you are done. If the command following a semicolon is a root node, precede it with a colon (:).
Series 2200 Programmable DC Power Supplies Reference Manual Section 3: Remote operation You can use upper case, lower case, or a mixture of both. No embedded spaces are allowed between or within nodes. :SOURCE:FREQUENCY 10MHZ is the same as :source:frequency 10mhz and :SOURCE:frequency 10MHZ No embedded spaces are allowed between or within nodes.

Indicates that an operation event has occurred. 6 RQS 6 MSS Request Service. Obtained from a serial poll. Shows that the power supply requests service from the GPIB controller. Master Status Summary. Obtained from *STB? query. Summarizes the OSB, ESB, MAV, QSB, and EQS bits in the SBR. 5 ESB Event Status Bit.
Series 2200 Programmable DC Power Supplies Reference Manual Appendix C: Status model Operation condition register (OCR) The operation condition register is made up of eight bits, which note the occurrence of events as shown here. Figure 28: Operation Condition Register (OCR) OCR bit functions Bit Function 7 (MSB) ———— This bit is not used. 6 ———— This bit is not used. 5 RUN Running List. Indicates that the power supply is executing a lis 4 3 TBF CC 2 CV Trace Buffer Full.
Appendix C: Status model Series 2200 Programmable DC Power Supplies Reference Manual SESR bit functions Bit Function 7 (MSB) ———— This bit is not used. 6 ———— This bit is not used. 5 ———— This bit is not used. 4 3 PS RI Protection Shutdown. Remote Inhibit. This bit indicates the state of the Remote Inhibit input. 2 UNR Unregulated. Indicates that the power supply has gone out of regulation. 1 OT 0 (LSB) OV Over Temperature.
Series 2200 Programmable DC Power Supplies Reference Manual Appendix C: Status model Enable registers This topic describes the following four types of enable registers: Event status enable register (ESER) (on page C-7) Service request enable register (SRER) (on page C-7) Operation enable register (OENR) (on page C-8) Questionable enable register (QENR) (on page C-8) ESER, SRER, OENR, and QENR allow you to select which events are reported to the status byte register (SBR).
Appendix C: Status model Series 2200 Programmable DC Power Supplies Reference Manual Operation enable register (OENR) The OENR consists of bits defined exactly the same as bits 0 through 7 in the OEVR. You can use this register to control whether or not the operation status bit (OSB) in the SBR is set when an event occurs and the corresponding OEVR bit is set. Use the STATus:OPERation:ENABle command to set the bits in the OENR. Use the STATus:OPERation:ENABle? query to read the contents of the OENR.
Series 2200 Programmable DC Power Supplies Reference Manual Appendix C: Status model Error/event queue The Event Queue stores detailed information on up to 32 events. When 32 events stack up in the Event Queue, the 32nd event is replaced by event code 350, "Queue Overflow.
Appendix C: Status model Series 2200 Programmable DC Power Supplies Reference Manual Command errors The following table shows the command error messages generated by improper syntax. Check that the command is properly formed and that it follows the rules in the section on command Syntax.
Series 2200 Programmable DC Power Supplies Reference Manual Appendix C: Status model System errors The following table lists the system errors that can occur during power supply operation.
Appendix C: Status model Series 2200 Programmable DC Power Supplies Reference Manual Device dependent errors The following table lists the device errors that can occur during power supply operation. These errors may indicate that the power supply needs repair.
