Command Set Organization
The command set is divided into common commands, root level commands
and eight sets of subsystem commands. Each of the ten groups of commands
is described in the
HP 54620A/C Programmer’s Reference , which is
supplied as an online help file for Microsoft Windows. See chapter 8 for
information about installing and using the help file.
The commands are shown using both uppercase 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 logic analyzer. Each command listing contains a description of the
command and its arguments and the command syntax. Some commands have
a programming example.
The subsystems are listed below:
•
SYSTem—controls some basic functions of the logic analyzer.
•
ACQuire—sets the parameters for acquiring and storing data.
•
DISPlay—controls how waveforms, the graticule, and text are displayed
and written on the screen, including the color palette for the HP 54620C
(color) logic analyzer.
•
LCHannel—controls all logic analyzer functions associated with individual
channels or groups of channels, including channel color for the HP 54620C
(color) logic analyzer.
•
MEASure—selects the automatic measurements to be made and controls
time markers.
•
TIMebase—controls all horizontal sweep functions.
•
TRIGger—controls the trigger modes and parameters for each trigger type.
•
WAVeform—provides access to waveform data.
