PEL-3000 Programming Manual COMMNAND OVERVIEW The Command overview chapter lists all PEL-3000 commands in functional order as well as alphabetical order. The command syntax section shows you the basic syntax rules you have to apply when using commands. Command Syntax Partial compatibility Compatible Standard IEEE488.2 Command Structure SCPI (Standard Commands for Programmable Instruments) commands follow a tree-like structure, organized into nodes. Each level of the command tree is a node.
PAGE 19
COMMNAND OVERVIEW Command types There are a number of different instrument commands and queries. A command sends instructions or data to the unit and a query receives data or status information from the unit. Command types Simple A single command with/without a parameter Example :CONFigure:RESPonse MAX Query A query is a simple or compound command followed by a question mark (?). A parameter (data) is returned. Example :CONFigure:RESPonse? Compound Two or more commands on the same command line.
PAGE 20
PEL-3000 Programming Manual nodes. Example Command Forms CONFigure:VON MAX;:CONFigure:VDELay MIN Commands and queries have two different forms, long and short. The command syntax is written with the short form of the command in capitals and the remainder (long form) in lower case. The commands can be written in capitals or lower-case, just so long as the short or long forms are complete. An incomplete command will not be recognized. Below are examples of correctly written commands.

COMMNAND OVERVIEW Status Registers To program the PEL-3000 Series effectively, the Status Register structure needs to be understood. This chapter explains in detail the structure of the status registers. Overview The status registers are used to determine the status of the electronic load. The status registers maintain the status of the protection conditions, load conditions and channel conditions of the load modules.

PEL-3000 Programming Manual Enable Register The Enable register determines which status event(s) are enabled. Any status events (CC, CV, CR, CP, PRUN) that are enabled will set the corresponding bit in the CSummary Event Register. Questionable Status Registers Overview The Questionable Status Registers will show if any faults or errors have occurred.
PAGE 157
COMMNAND OVERVIEW PTR/NTR Filters The PTR/NTR (Positive/Negative transition) register determines the type of transition conditions that will trigger an event. Only the CSummary Status Register, Questionable Status Register and Operation Status Register can be transition programmed. Event Register The Event Register indicates if an event has been triggered according to the transition settings from the PTR/NTR Register. Enable Register The Enable register determines which status event(s) are enabled.
PAGE 158
PEL-3000 Programming Manual Condition Register The condition register indicates the operating state of the unit. The condition register can only be changed by a change in the condition of operating state. Reading the condition register does not change the state of the condition register. PTR/NTR Filters The PTR/NTR (Positive/Negative transition) register determines the type of transition conditions that will trigger an event.
PAGE 159
COMMNAND OVERVIEW Events Bits OPC: The operation complete bit is set when all selected pending operations are complete. This bit is set in response to the *OPC command. RQC: Not used. QUE: The query error bit is set when there is an error reading the output queue. This can be caused by trying to read the output queue when there is no data in it. DDE: The Device Dependent Error indicates a memory error/lost memory or failure of the self-test.
PAGE 160
PEL-3000 Programming Manual Status Byte Register Overview The Status Byte register consolidates the status events of all the status registers. The Status Byte register can be read with the *STB? query or a serial poll and can be cleared with the *CLS command. Status Byte Register Bit Position Condition Bit weight Status Bits 158 7 6 OPER MSS 128 64 5 ESB 32 4 3 2 1 MAV QUES CSUM ERR 16 8 4 2 0 0 1 ERR: The ERR bit is set when there is a message in the error queue.
PAGE 161
COMMNAND OVERVIEW Service Request Register Overview The Service Request Generation Register determines which events in the Status Byte Register will generate Service Requests. It is essentially the Status Byte Enable Register. The bit events are the same as the Status Byte Register, minus the MSS/RQS bit.
