Command Set Organization - Agilent Technologies 54621A Programmer's Manual

Command Set Organization

The command set is divided into common commands, root level commands and
sets of subsystem commands. Each of the groups of commands is described in
the Programmer's Reference, which is supplied as an online help file for
Microsoft Windows. See chapter 7, "Installing and Using the Programmer's
Reference" for information on installing and using the help file.
The commands shown use upper and lowercase letters. As an example,
AUToscale indicates that the entire command name is AUTOSCALE. To speed
up the transfer, the short form AUT is also accepted by the oscilloscope. Each
command listing contains a description of the command and its arguments and
command syntax. Some commands have a programming example.
The subsystems are listed below:
Subsystem Description
ACQuire sets the parameters for acquiring and storing data
CALibrate provides utility commands for determining the state of the calibration factor
protection switch
CHANnel<n> controls all oscilloscope functions associated with individual analog
channels or groups of channels
Common commands defined by IEEE 488.2 standard common to all instruments
DIGital controls all oscilloscope functions associated with individual digital
channels
DISPlay controls how waveforms, graticule, and text are displayed and written on
the screen
EXTernal controls the input characteristics of the external trigger input
FUNCtion controls functions in the Measurement/Storage Module
HARDcopy provides commands to set and query the selection of hardcopy device and
formatting options
MARKer provides commands to set and query the settings of X-axis markers (X1 and
X2 cursors) and the Y-axis markers (Y1 and Y2 cursors).
MEASure selects automatic measurements to be made and controls time markers
POD controls all oscilloscope functions associated with groups of digital
channels.
Root controls many of the basic functions of the oscilloscope and reside at the
root of the command tree
SYStem controls some basic functions of the oscilloscope
TIMebase controls all horizontal sweep functions
TRIGger controls the trigger modes and parameters for each trigger type
WAVeform provides access to waveform data
