Introduction to Programming
Common Commands within a Subsystem
Common Commands within a Subsystem
Common commands can be received and processed by the oscilloscope whether
they are sent over the bus as separate program messages or within other
program messages. If you have selected a subsystem, and a common command
is received by the oscilloscope, the oscilloscope remains in the selected
subsystem. For example, if the program message
":ACQUIRE:AVERAGE ON;*CLS;COUNT 1024"
is received by the oscilloscope, the oscilloscope turns averaging on, then clears
the status information without leaving the selected subsystem.
If some other type of command is received within a program message, you must
re-enter the original subsystem after the command. For example, the program
message
":ACQUIRE:AVERAGE ON;:AUTOSCALE;:ACQUIRE:AVERAGE:COUNT 1024"
turns averaging on, completes the autoscale operation, then sets the acquire
average count. Here, :ACQUIRE must be sent again after AUTOSCALE to re-
enter the ACQUIRE subsystem and set the count.
Selecting Multiple Subsystems
You can send multiple program commands and program queries for different
subsystems on the same line by separating each command with a semicolon.
The colon following the semicolon lets you enter a new subsystem. For example:
<program mnemonic><data>;:<program mnemonic><data><terminator>
:CHANNEL1:RANGE 0.4;:TIMEBASE:RANGE 1
Programming Getting Started
The remainder of this chapter explains how to set up the oscilloscope, how to
retrieve setup information and measurement results, how to digitize a
waveform, and how to pass data to the computer. The chapter, “Measure
Commands” describes sending measurement data to the oscilloscope.
You can Combine Compound and Simple Commands
Multiple program commands may be any combination of compound and simple
commands.
