Introduction
Computers communicate with the instrument by sending and receiving
messages over the HP-IB bus. Programming commands are normally sent
as ASCII character strings embedded inside output statements of your
programming language. Input statements are used to read in responses from
the instrument.
For example, HP 9000 Series 200/300 BASIC uses the
OUTPUT
statement for
sending commands and queries. After a query is sent, the response is usually

Introduction
Program Message Terminator
The instructions within the program message are executed after the instruction terminator is received.
The terminator may be either a New Line (NL) character, an End-Or-Identify (EOI) asserted, or a
combination of the two. All three ways are equivalent. Asserting the EOI sets the EOI control line low
on the last byte of the data message. The NL character is an ASCII linefeed (decimal 10).
The NL (New Line) terminator has the same function as an EOS (End Of String) and EOT (End Of Text)
terminator.

Sending Commands to the Instrument
It's easy to send a command to the instrument. Simply create a command
string, and place the string in your program language's output statement. For
commands other than Common Commands, include a semicolon (;) before
the subsystem name.For example, the following string sends the DELAY
command in the Timebase subsystem.

commands
You can send commands and program queries from dierent subsystems on
the same line. Simply precede the new subsystem by a semicolon (;) followed
by a colon (:). In the following example, the colon before CHANNEL1 allows
you to send a command from another subsystem.
OUTPUT 707;":TIMEBASE:REFERENCE CENTER;:CHANNEL1:OFFSET 0"
If a subsystem has been selected and a Common Command is received by the
instrument, the instrument remains in the selected subsystem. For example,

Returning Data to the Computer
Data is requested from the instrument using a query. Queries can be used
to nd out how the instrument is currently congured. They are also used
to get results of measurements made by the instrument, with the query
actually activating the measurement. Responses are returned as uppercase
letters.You can select either the long or short form responses with the
SYSTEM:LONGFORM command.
Queries usually take the form of a command followed by a question mark (?).

Sending and Receiving Binary Data
You will often need to send or receive binary data. An example is receiving
binary data via the :WAVEFORM:DATA? command. This is done using the
denite-length block data format. This format allows any type data to be
transmitted as a series of 8-bit binary bytes. This is particularly useful for
sending large quantities of data or 8-bit extended ASCII codes.
With denite-length block data format, the binary data is preceded by several
bytes which describe the length of the data.

Making a Measurement
Capture data with the
DIGITIZE command
When the DIGITIZE command is sent to an instrument, the specied channel
signal is digitized with the current ACQUIRE parameters.To obtain waveform
data, you must specify the WAVEFORM parameters for the waveform data
prior to sending the :WAVEFORM:DATA? query.
When the DIGITIZE process is complete, the acquisition is stopped, and the
captured data can then be measured by the instrument or transferred to the
computer for further analysis. The captured data consists of two parts: the
waveform data record and the preamble.
After changing the instrument conguration, the waveform buers are
cleared. Before doing a measurement, the DIGITIZE command should be sent

Programming
Making a Measurement
Returning the data to
the computer
After receiving the :WAVEFORM:DATA? query, the instrument passes
the waveform information when addressed to talk. Digitized waveforms
are passed from the instrument to the computer by sending a numerical
representation of each digitized point. The format of the numerical
representation is controlled with the :WAVEFORM:FORMAT command and
may be selected as BYTE, WORD, or ASCII.
The easiest method of entering a digitized waveform depends on data
structures, available formatting, and I/O capabilities.You must scale the
integers to determine the voltage value of each point. These integers are
passed starting with the leftmost point on the instrument's display.For more
information, refer to the chapter on the Waveform subsystem.

The following gures show the dierent status reporting data structures and
how they work together.To make it possible for any of the Standard Event
Status Register bits to generate a summary bit, the bits must be enabled.
These bits are enabled by using the *ESE common command to set the
corresponding bit in the Standard Event Status Enable Register.
To generate a service request (SRQ) interrupt to an external controller,at
least one bit in the Status Byte Register must be enabled. These bits are

Status Byte Register
(STB)
The Status Byte register is the summary-level register in the status reporting
structure. It contains summary bits that monitor activity in the other status
registers and queues. The Status Byte Register is a live register. That is,its
summary bits are set and cleared by the presence and absence of a summary
bit from other event registers or queues.
If the Status Byte Register is to be used with the Service Request Enable
Register to set bit 6 (RQS/MSS) and to generate an SRQ, at least one of the
summary bits must be enabled, then set. Also, event bits in all other status
registers must be specically enabled to generate the summary bit that sets
the associated summary bit in the Status Byte Register.

User
(UER)
To make it possible for any of the Standard Event Status Register bits to be
able to generate a summary bit, rst enable the bit. Enable the bit by using
the *ESE (Event Status Enable) common command to set the corresponding
bit in the Standard Event Status Enable Register.
Set bits are read with the *ESE? query.
For example, suppose your application requires an interrupt whenever any
type of error occurs. The error related bits in the Standard Event Status
Register are bits 2 through 5. The sum of the decimal weights of these bits is
60. Therefore, you can enable any of these bits to generate the summary bit
by sending:

Queues
As errors are detected, they are placed in an error queue. This queue is
rst in, rst out. If the error queue overows, the last error in the queue is
replaced with error0350, \Queue overow." Any time the queue overows,
the least recent errors remain in the queue, and the most recent error is
discarded. The length of the instrument error queue is 30 (29 positions for
the error messages, and 1 position for the \Queue overow" message).

Instrument Block Diagram
As the following block diagram shows, the digitizer samples the applied signal
and converts it to a digital signal. The FISO holds the data until the system
bus is ready for the data. The output of the FISO is raw data, and it is used
as an address to the calibration read-through table (cal table).
The cal table automatically applies the calibration factors to the raw
that the output of the cal table is calibrated data.

Instrument Block Diagram
Notice that averaging is turned on or o before the data is stored in the
channel memories. That means once the data is acquired, if you need to turn
averaging on or o before making any measurements, you must reacquire the
data.
Also, you may notice that postprocessing the data includes calculating
functions, storing data to the waveform memories, transferring data over the
HP-IB bus, or transferring data to and from the disk.
After the measurements are performed, the data is sent through the display
portion of the instrument. Notice that connected dots is a display feature,and
that it has no inuence on the measurement results. The pixel memory is
also part of the video RAM, which is past the point where the measurements

Common Commands
Common commands are dened by the IEEE 488.2 standard. They control
generic device functions which could be common among many dierent
types of instruments. Common commands can be received and processed by
the instrument whether they are sent over the HP-IB as separate program
messages or within other program messages.
The following common commands and queries are implemented in this
instrument:
*CLS
*ESE
*ESR?
*IDN?

Descriptions
Common commands can be received and processed by the instrument
whether they are sent over the HP-IB as separate program messages or within
other program messages. If a subsystem is currently selected and a common
command is received by the instrument, the instrument remains in the
selected subsystem. For example, if the program message:
"ACQUIRE:TYPE AVERAGE;*CLS;COUNT 1024"
is received by the instrument, the instrument sets the acquire type, clears
the status information, and then sets the acquire count without leaving the
selected subsystem.
