These non-unit code terminators originate in the controller's language.
A terminated entry without a units code defaults to the fundamental units for the function activated. The default
units of power depend upon the amplitude readout units selected.
Front-Panel Data Entry During Remote Control
Data may also be entered from the front panel when the analyzer is in remote control. This is done by following the
analyzer command with the secondary keyword, El? The syntax diagrams show which comands can be followed
by EI? EP pauses program operation until data is entered from the front panel and terminated with one of the units
keys listed in the Units Code table. Program operation then resumes. EP is especially useful when it is part of a
programming routine that is stored in a soft key.
Custom Soft key Functions
The spectrum analyzer has soft keys that can be loaded into up to 16K bytes of memory, with or without a
controller. These soft keys remain in nonvolatile memory for the life of the internal battery, which lasts for one year.
The functions of the soft keys are defined with the KEYDEF command. The original contents of a soft key are
erased when the key is defined a second time with the KEYDEF command, or when the DISPOSE command is
executed.
The soft keys can be executed four ways. To execute a soft key remotely, execute the KEYEXC command, or
define the soft key as part of a user-defined function. Then, whenever the function name is encountered, the soft
key is executed. (See FUNCDEF command.) Soft keys can also be nested inside another soft key. Thus, executing
one key actually can cause the execution of several keys.
To manually execute a soft key from the front panel, press m , the key number, and then press
