See also: ● Structure and syntax of the instrument messages: Chapter A.1.
R&S®NGL200 Additional Basics on Remote Control Messages and Command Structure are device-specific, however, their syntax follows SCPI rules as permitted by the standard. Instrument responses Instrument responses (response messages and service requests) are messages which the instrument sends to the controller after a query. They can contain measurement results, instrument settings and information on the instrument status.
R&S®NGL200 Additional Basics on Remote Control Messages and Command Structure Syntax for Device-Specific Commands For demonstration purposes only, assume the existence of the following commands for this section: ● MEASure:CURRent[:DC]? ● MEASure:VOLTage[:DC]? ● FUSE[:STATe] {ON | OFF | 0 | 1} ● FUSE[:STATe]? Long and short form The mnemonics feature a long form and a short form. The short form is marked by uppercase letters, the long form corresponds to the complete word.
R&S®NGL200 Additional Basics on Remote Control Messages and Command Structure Special characters Table A-2: Special characters | A vertical stroke in parameter definitions indicates alternative possibilities in the sense of "or". The effect of the command differs, depending on the used parameter.
R&S®NGL200 Additional Basics on Remote Control Messages and Command Structure ● MINimum and MAXimum denote the minimum and maximum value. Example: VOLT:PROT? MAX Returns the maximum numeric value. Boolean parameters Boolean parameters represent two states: ● On (logically true), is represented by "On" or the numeric value "1" ● Off (logically false), is represented by "Off" or the numeric value "0" The instrument returns the numerical value when queried.
R&S®NGL200 Additional Basics on Remote Control Status Reporting System A.2 Command Sequence and Synchronization A sequential command finishes the execution before the next command is starting. To make sure that commands are actually carried out in a certain order, each command must be sent in a separate command line. As a rule, send commands and queries in different program messages. A.2.
R&S®NGL200 Additional Basics on Remote Control Status Reporting System A.3.1 Structure of a SCPI Status Register Each standard SCPI register consists of 2 or 3 parts (Event, Condition and Enable register). Each part has a width of 16 bits and has different functions. The individual bits are independent of each other, i.e. each hardware status is assigned a bit number which is valid for all 2 or 3 parts. Bit 15 (the most significant bit) is set to zero for all parts.
R&S®NGL200 Additional Basics on Remote Control Status Reporting System Figure A-1: Structure of the status QUEStionable register CONDition ● The CONDition register queries the actual state of the instrument. If you want to query the constant voltage or current mode, you have to use the CONDition register. The CONDition register delivers a "1" (first bit set) in constant current mode (CC) and a "2" (second bit set) in constant voltage mode (CV).
R&S®NGL200 Additional Basics on Remote Control Status Reporting System The description of registers is only used for general explanation. Due to the complexity, we recommend the general accessible SCPI standard document for more detailed information. For further description of the status register, see Chapter 7.10, "Status Reporting", on page 127. Event Status Register (ESR) and Event Status Enable Register (ESE) The ESR is defined in IEEE 488.2.
R&S®NGL200 Additional Basics on Remote Control Status Reporting System STATus:QUEStionable Register This register contains information about different states which can occur. It can be read using the commands STATus:QUEStionable:CONDition? and STATus:QUEStionable[:EVENt]?. See also Figure A-1. Table A-5: Bits of the STATus:QUEStionable register Bit No. Meaning 0 Voltage This bit is set while the instrument is in constant current mode (CC). The voltage is regulated and the current is constant.
