Programming the Transmitter Tester
The E4406A VSA Series Transmitter Tester has several different
measurement modes. The measurement commands that are available
to you change, depending on which mode is selected. Use
INSTrument:SELect to select the desired mode.
Most modes are optional and must be installed into instrument memory
before they can be used. See “Installing Optional Measurement
Personalities” on page 44, if your measurement mode is not installed.
The SYSTem:HELP:HEADers? command provides a list of all the
commands available in the mode you have currently selected. The
programming commands for each optional mode are documented
separately. The specific measurements available in a particular mode
are indicated below.
