Aeroflex 3412 - Output Control Commands; Mod. Source On;Off, RPP, RF On;Off; Output Subsystem

4-17
Output control commands
(OUTPut subsystem)
Mod. source on/off, RPP, RF on/off
Commands for:
• Turning each modulation path on or off
• Querying the state of, and resetting, RPP
• Turning the RF output on or off.
The OUTput subsystem effectively controls the switching of modulation paths within the
instrument. Fig. 4-1 on page 4-19 is a representation of the OUTput and SOURce commands and
their relationship to the sources. You can see from this that the OUTput commands control the
outputs of the sources as well as the combined modulation output.
Not shown on this diagram is the OUTput[:POWer][:STATe] command, which controls the
instrument’s final RF output.
Note that this diagram is intended to show the effect of commands on the routing of sources and
modulation paths, and does not necessarily represent actual hardware in the instrument.
