5.5 RF Signal and Analog Modulations - RF Block
5.5.1 Overview of RF Signal
Settings for the RF output signal and analog modulation are made under "RF Signal" and
"Analog Modulations". These settings can be accessed in the block diagram by way of
the "RF/A MOD" function block, or by means of the menu with the same name which is
opened using the MENU key.
The function block is available for the basic unit (R&S SMU + frequency option R&S SMU-
B10x) without additional equipment options. An additional frequency option (R&S
SMU-20x) is required for a two-path instrument.
For instruments equipped with one of the frequency options it is possible to install the
option High Power (R&S SMU-B3x options) separately for both RF paths.
5.5.1.1 RF Output
To activate and deactivate the RF output signal, use one of the following alternatives:
●
directly using the TOGGLE ON/OFF key (the function block must be highlighted
beforehand)
●
by means of the RF ON/OFF key (the current entry focus is irrelevant)
●
by changing the state of the "RF/A Mod" functional block (see "State RF"
on page 195)
●
by enabling/disabling the RF in the "Configure" menu of the "RF/A Mod" block (see
"RF Output State" on page 195).
Both RF output signals are always deactivated in the case of two-path instruments. The
previous state is restored when the signals are reactivated.
The current state of the RF output (activated and deactivated) is indicated in the block
diagram by means of the different block color and the status of the "On" checkbox. The
disconnected connection to the output is additionally shown when the output is deacti-
vated.
Active analog modulation is also indicated in the block.
