Preparing for Use

Writing Your First Program

Use variables for function values. List the variables at the beginning of the program.

Perform the measurement manually, keeping track of the key functions used. Identify the programming commands equivalent to these front panel keys.

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 59.

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.
