COMMAND SUMMARY
Acquisition
Communication
This section of the manual lists all commands and queries recog-
nized by the oscilloscope. For easy reference the listings are
arranged in alphabetical order. Each command starts on a new
page and the name (header) of the command is given in both the
long and short forms. Below each name (header) it is indicated
whether it denotes a command only, a command as well as a
query, or a query only. For those headers that may be used to
command an action, for example to modify a setup parameter, or
to obtain some information such as the current value of a setup
parameter, the query form is derived by appending a question
mark (?) immediately to the header without intervening spaces.
The description of each command starts with a short explanation
of the function performed by it, followed by a presentation of the
formal syntax. In the formal syntax the header appears in mixed
mode characters with the characters used to construct the short
form shown in upper case.
Where applicable, the syntax of the query form is given along with
the format of the response the oscilloscope will produce.
For most commands the description terminates with a short exam-
ple illustrating a typical use of the command. The GPIB examples
assume that the controller is equipped with a National Instruments
interface board, and they show calls to the National Instruments
interface subroutines in BASIC. The device name of the oscillo-
scope has been defined as "SCOPE%".
The following is an overview of the commands grouped according
to their functionality.
To control the acquisition of waveforms:
ARM_ACQUISITION, AUTO_SETUP, BANDWIDTH_LIMIT,
INTERLEAVED, SAMPLE_CLOCK, SEGMENTS, STOP,
*TRG, WAIT.
To select vertical input parameters to capture waveforms:
ATFENUATION, COUPLING, OFFSET, VOLT_DIV.
To select time-base parameters to capture waveforms:
TIME_DIV, TRIG_DELAY.
To select trigger conditions to capture waveforms:
TRIG_COUPLING, TRIG_LEVEL, TRIG_MODE,
TRIG PATI’ERN, TRIG_SELECT, TRIG_SLOPE.
To set communication characteristics:
COMM_FORMAT, COMM_HEADER, COMM_HELP,
COMM_ORDER, COMM_RS232, PERSIST_SETUP.
