Mandatory LO IN Frequency
Displays the frequency that must be applied as external LO frequency.
Remote command:
[:SOURce<hw>]:FREQuency:LOSCillator:INPut:FREQuency? on page 822
LO OUT Frequency
Displays the current LO frequency at the LO Out connector.
Remote command:
[:SOURce<hw>]:FREQuency:LOSCillator:OUTPut:FREQuency? on page 823
Show Connector
Accesses a dialog that displays the physical location of the selected connector on the
front/rear panel of the instrument.
6.9.4 How to Configure Cascaded Instruments
This section describes how you can find out the location of the LO signal connectors
(LO In/Out). You can also find instructions for configuring the LO signals of several dis-
connected signal generators.
To find the physical Location of the LO In/Out connectors
The LO In and LO Out connectors are located on the rear panel. To find out the exact
position, proceed as follows:
1. In the block diagram, select the "T/E/P/L/V" status indication field above the "RF"
block.
2. Select "LO In" > "Show".
3. Observe the connectors's position on the "Rear" panel.
See also Chapter 10.2.4, "RF Connectors Settings", on page 519.
To configure LO coupling with cascaded instruments to achieve phase coher-
ence
The LO Coupling function can be used to generate beamforming signals.
The test setups in the following examples represent possible applications and provide
information about the coupling modes set in the signal generators. For the configura-
tion via remote control, see the examples in Chapter 12.16.6, "SOURce:FREQuency
Subsystem", on page 820.
The first test setup example represents all variants of the coupling modes, and
describes step-by-step how to configure each of the Rohde & Schwarz signal genera-
tors. The following examples show further conceivable test setups. To configure these
test setups, proceed similarly as shown in the first example.
