Description
INITiate Command Functions
The INITiate subsystem is used to:
• Start (activate) individual or multiple (concurrent) measurements.
• Turn individual measurements off.
• Determine the number of measurements currently active (INIT:COUNT?).
• Determine the names of the measurements currently active (INIT:ON?).
• Determine which measurements are finished (INIT:DONE?).
What Happens When a Measurement is INITiated?
When a measurement is started using INITiate commands, a new measurement cycle is started. If the
selected measurement is currently in a measurement cycle, it is aborted. Also, if a timeout is specified, the
timeout period is begun.
The INITiate subsystem is derived from SCPI, but has some modifications to make it more
NOTE
compatible with the manual operation of the test set. Most notably, the choice of single or
continuous measurement triggering is made using the SETup subsystem.
INITiate Programming Examples (how INIT commands are used)
The INITiate command is used to start measurements. INITiate commands allow multiple measurements to
be started without waiting for other measurement processes to complete. For example, the following code
starts the Transmit Power and PFER measurements, and then uses the INITiate:DONE? command in a loop
to query the status of these measurements, see
When the measurements are done, the FETCh command is used to acquire the results, and the results are
entered into variables in the controlling application. The program ends when the INITiate:DONE? command
returns the string "NONE" indicating that all initiated measurements have gone through the measuring state
see "Measurement States" on page
Trigger arming for each measurement is controlled in the SETup subsystem. The choices are
NOTE
single or continuous. The best practice (during remote operation) is to use single measurement
mode. This simplifies the tasks of starting concurrent measurements, then using the INIT
subsystem commands to determine which measurements are ready to be FETChed.
