Programming Fundamentals The purpose of this chapter is to serve as a reminder of SCPI (Standard Commands for Programmable Instruments) fundamentals to those who have previous experience in programming SCPI. This chapter is not intended to teach you everything about the SCPI programming language.

Page 17: Creating Valid Commands
Programming Fundamentals Creating Valid Commands Creating Valid Commands Commands are not case sensitive and there are often many different ways of writing a particular command. These are examples of valid commands for a given command syntax: Command Syntax Sample Valid Commands The following sample commands are all [:SENSe]:BANDwidth[:RESolution] identical.

Programming Fundamentals Command Notation Syntax Command Notation Syntax A typical command is made up of key words set off by colons. The key words are followed by parameters that can be followed by optional units. Example: :TRIGger:SEQuence:VIDeo:LEVel 2.5V The instrument does not distinguish between upper and lower case letters.

Page 24: Overview Of Hp-Ib
Programming Fundamentals Overview of HP-IB Overview of HP-IB HP-IB Instrument Nomenclature An instrument that is part of an HP-IB network is categorized as a listener, talker, or controller, depending on its current function in the network. Listener A listener is a device capable of receiving data or commands from other instruments.
Page 25 (sometimes called: local, resume). • A clear function that causes all HP-IB instruments, or addressed instruments, to assume a cleared condition. The deﬁnition of clear is unique for each instrument (sometimes called: clear, reset, control, send).
Page 26: Settings For The Serial Interface
Programming Fundamentals Overview of RS-232 Overview of RS-232 Serial interface programming techniques are similar to most general I/O applications. Due to the asynchronous nature of serial I/O operations, special care must be exercised to ensure that data is not lost by sending to another device before the device is ready to receive.
Page 27: Modem Line Handshaking
Programming Fundamentals Overview of RS-232 Modem Line Handshaking To use modem line handshaking for data transfer you would consider the following tasks: 1. Set Data Terminal Ready and Request-to-Send modem lines to active state. 2. Check Data Set Ready and Clear-to-Send modem lines to be sure they are active.

Page 31: Hp Esa Status Registers
HP ESA Status Registers This chapter describes what status registers are and how to use them. Also provided is a comprehensive description of all bits of the registers in HP ESA analyzers.
Page 32: Using The Analyzer Status Registers
HP ESA Status Registers Using the Analyzer Status Registers Using the Analyzer Status Registers The status system is comprised of multiple registers which are arranged in a hierarchical order. The lower-priority status registers propagate their data to the higher-priority registers in the data structures by means of summary bits.
Page 33: Using The Status Registers
HP ESA Status Registers Using the Analyzer Status Registers 1. Determine which register contains the bit that reports the condition. 2. Send the unique SCPI query that reads that register. 3. Examine the bit to see if the condition has changed.
Page 34: Setting And Querying The Registers
HP ESA Status Registers Using the Analyzer Status Registers • Monitor a change in the condition of a particular bit, or bits. Once you have enabled a bit, the analyzer will monitor it for a change in its condition. The transition registers are preset to register the conditions going from 0 to 1, positive transitions.
Page 35 HP ESA Status Registers Using the Analyzer Status Registers 3. Send GPIB commands to enable the bit that monitors the condition and to enable the summary bits that report the condition to the RQS bit. 4. Enable the controller to respond to service requests.
Page 36 HP ESA Status Registers Using the Analyzer Status Registers When you read the analyzer status byte register with a serial poll, the NOTE RQS bit is reset to 0. Other bits in the register are not affected. Restarting a measurement (:INITiate command) can cause the measuring bit to pulse low, which causes an SRQ if the status register is conﬁgured to SRQ on end-of-measurement.

For example, assume that you want to enable bit 7 so that whenever the operation status summary bit is set to 1 it will trigger a service request.
Page 41 HP ESA Status Registers Using the Analyzer Status Registers Summary Bit Creation Through Condition, Filters, and Events Registers Status registers (except for the Status Byte Register) consist of registers whose contents are programmed in order to produce status summary bits. These summary bits are then manipulated as follows: The condition register passes summary bits to the negative and positive transition ﬁlters, after which they are stored in the event register.

Page 369: Error Messages
Error Messages Error Messages Error Messages The analyzer can generate various messages that appear on the display during operation. There are four types of messages. • Status Messages appear on the right side of the analyzer display and/or set status bits in the SCPI Status Register system. These messages indicate a condition that may result in erroneous data being displayed.

Page 375: Error Queues
Error Messages Error Queues Error Queues When a user-error condition occurs in the instrument as a result of SCPI activity, it is reported to both the front-panel display-error queue and the SCPI (remote interface) error queue. If it is a result of front-panel activity it reports to the front panel display error queue, and may also report to the SCPI error queue depending on the error.
Page 376: Error Message Format
Error Messages Error Message Format Error Message Format The system-deﬁned error numbers are chosen on an enumerated (“1 of N”) basis. The error messages are listed in alphabetical order within each error message type section. In this chapter, an explanation is included with each error to further clarify its meaning.
