6 SCPI Basics
The POWer 10DBM command is missing the leading colon and when sent, it causes confusion
because the N8211A/N8212A cannot find POWer at the POWer:OFFSet level. By adding the
leading colon, the current path is reset to the root. The following shows the correct program
message:
:POWer:OFFSet 5DB;:POWer 10DBM
Example 4
FREQ 500MHZ;POW 4DBM
In this example, the keyword short form is used. The program message is correct because it
utilizes the default nodes of :FREQ[:CW] and :POW[:LEVel]. Since default nodes do not
affect the current path, it is not necessary to use a leading colon before FREQ or POW.
File Name Variables
File name variables, such as "<file name>", represent three formats, "<file name>",
"<file name@file type>", and "</user/file type/file name>". The following
shows the file name syntax for the three formats, but uses "FLATCAL" as the file name in
place of the variable "<file name>":
Format 1 "FLATCAL"
Format 2 "FLATCAL@USERFLAT"
Format 3 "/USER/USERFLAT/FLATCAL"
Format 2 uses the file type extension (@USERFLAT) as part of the file name syntax. Format 3
uses the directory path which includes the file name and file type. Use Formats 2 and 3 when the
command does not specify the file type. This generally occurs in the Memory (:MEMory) or
Mass Memory (:MMEMory) subsystems. The following examples demonstrate a command
where Format 1 applies:
Command Syntax with the file name variable :MEMory:STORe:LIST "<file name>"
Command Syntax with the file name :MEMory:STORe:LIST "SWEEP_1"
