Programming Fundamentals SCPI Language Basics Parameters in Commands There are four basic types of parameters: booleans, keywords, variables and arbitrary block program data. ON|OFF|0|1 This is a two state boolean-type parameter. The numeric value 0 is equivalent to OFF. Any numeric value other than 0 is equivalent to ON.
Page 65 Programming Fundamentals SCPI Language Basics <voltage> A voltage parameter is a rational number followed by optional units. The default units are V. Acceptable units include: Volts, V, MV, UV. <power> <ampl> A power parameter is a rational number followed by optional units.
Page 66 Programming Fundamentals SCPI Language Basics <bit_pattern> A bit pattern parameter speciﬁes a series of bits rather than a numeric value. The bit series is the binary representation of a numeric value. There are no units. Bit patterns are most often speciﬁed as hexadecimal numbers, though octal, binary or decimal numbers may also be used.
Page 67: Putting Multiple Commands On The Same Line
Programming Fundamentals SCPI Language Basics Putting Multiple Commands on the Same Line Multiple commands can be written on the same line. This can be used to provide a shorter notation for sending a series of related commands in the same subsystem. Commands for different subsystems can be put on the same line but this can make your program harder to understand.

Page 69: Using The Instrument Status Registers
Programming Fundamentals Using the Instrument Status Registers Using the Instrument Status Registers You can determine the state of certain instrument hardware and ﬁrmware events and conditions by programming the status register system. The Figure on page 76 shows all the instrument status registers and their hierarchy.
Page 70: What Are The Status Registers
Programming Fundamentals Using the Instrument Status Registers What are the Status Registers? The status system is comprised of multiple registers which are arranged in a hierarchical order. The lower-level status registers propagate their data to the higher-level registers in the data structures by means of summary bits.
Page 71 Programming Fundamentals Using the Instrument Status Registers What are the Status Register SCPI Commands Most monitoring of the instrument conditions is done at the highest level using the IEEE common commands indicated below. Complete command descriptions are available in the IEEE commands section at the beginning of the language reference.
Page 72: Why Would You Use The Status Registers
Programming Fundamentals Using the Instrument Status Registers Why Would You Use the Status Registers? Your program often needs to be able to detect and manage error conditions or changes in instrument status. There are two methods you can use to programmatically access the information in status registers: •...
Page 73 Programming Fundamentals Using the Instrument Status Registers You can monitor conditions in different ways. • Check the current instrument hardware and ﬁrmware status. Do this by querying the condition registers which continuously monitor status. These registers represent the current state of the instrument.
Page 74: Using A Status Register
Programming Fundamentals Using the Instrument Status Registers Using a Status Register Each bit in a register is represented by a numerical value based on its location. See Figure 2-1 below. This number is sent with the command, to enable a particular bit. If you want to enable more than one bit, you would send the sum of all the bits that you are interested in.
Page 75 Programming Fundamentals Using the Instrument Status Registers Generating a Service Request To use the SRQ method, you must understand how service requests are generated. Bit 6 of the status byte register is the request service (RQS) bit. The RQS bit is set whenever something (that it has been conﬁgured to report using *SRE) changes.
Page 76: Overall Status Register System
Programming Fundamentals Using the Instrument Status Registers Overall Status Register System Chapter 2...
Page 77: Status Byte Register
Programming Fundamentals Using the Instrument Status Registers Status Byte Register The RQS bit is read and reset by a serial poll. MSS (the same bit position) is read, non-destructively by the *STB? command. If you serial poll bit 6 it is read as RQS, but if you send *STB it reads bit 6 as MSS. For more information refer to IEEE 488.2 standards, section 11.
Page 78 Programming Fundamentals Using the Instrument Status Registers Description 0, 1 These bits are always set to 0. A 1 in this bit position indicates that the SCPI error queue is not empty. The SCPI error queue contains at least one error message. A 1 in this bit position indicates that the data questionable summary bit has been set.
Page 79: Sre
Programming Fundamentals Using the Instrument Status Registers In addition to the status byte register, the status byte group also contains the service request enable register. This register lets you choose which bits in the status byte register will trigger a service request.

Page 81 Programming Fundamentals Using the Instrument Status Registers Description A 1 in this bit position indicates that all pending operations were completed following execution of the *OPC command. This bit is always set to 0. (The instrument does not request control.) A 1 in this bit position indicates that a query error has occurred.
Page 82 Programming Fundamentals Using the Instrument Status Registers The standard event status register is used to determine the speciﬁc event that set bit 5 in the status byte register. To query the standard event status register, send the command *ESR?. The response will be the decimal sum of the bits which are enabled (set to 1).
Page 83: Operation And Questionable Status Registers
Programming Fundamentals Using the Instrument Status Registers Operation and Questionable Status Registers The operation and questionable status registers are registers that monitor the overall instrument condition. They are accessed with the STATus:OPERation and STATus:QUEStionable commands in the STATus command subsystem. Operation Status Register The operation status register monitors the current instrument measurement state.
