Preparing for Use
Writing Your First Program
• Select the instrument mode with INST:SELect. Set the mode setup
for things like your desired communications standard, channel
frequency and triggering.
• In the program, execute an instrument preset (*RST) and select
single-sweep mode (INITiate:CONTinuous OFF) before setting other
instrument functions.
• Use the MEASure group of commands, described in Chapter 5 ,
“Language Reference” . MEASure commands make the measurement
using the standard procedure and limits. You can alter some of the
measurement defaults by using commands in the SENSe:<meas>
subsystem. Once altered, use the CONFigure, FETCh, READ, and
INITiate commands to perform the measurements.
• The instrument can return different types of results for a particular
measurement. These results are described in the language reference
section on the MEASure group of commands.
• Execute the desired commands in logical order. Multiple SCPI
commands can be included on one line. See “SCPI Language Basics”
on page 61 .
File Naming Rules
File names for storing instrument states or other data files in the
analyzer should follow pc conventions.
• They can be up to eight characters long. In addition, they can have a
file extension up to three characters long. The analyzer can assign
the extension.
• They are not case sensitive. It does not matter whether you use
upper case or lower case letters when you enter them.
• They can only contain the letters A through Z and the numbers
0 through 9.
• They cannot contain any special characters (except the period that
separates the name from the extension).
• They cannot be identical to the name of another file in the same
directory.
