A connector with not specified direction is in a "Not Used" state.
Remote command:
[:SOURce]:INPut:USER<ch>:DIRection on page 678
:OUTPut:USER<ch>:DIRection on page 678
Signal
Determines the control signal that is input or output at the selected connector. Whether
the connector is used as an input or an output is selected by the parameter Direction
The Table 10-1 lists the available control signals.
"Global Trigger"
Input for triggering custom digital modulations, digital standards and
ARB. A trigger event affects the signal generation in all basebands for
which the "Global Trigger" signal is enabled.
"Global Clock"
Input for external clock signal for synchronizing the internal clocks in
all basebands to an externally applied clock signal. The active edge
can be configured.
"Global Next Segment"
Input next segment for triggering of multi-segment waveform files
(see Chapter 3.7, "Generating Multi-Segment Waveform Files",
on page 193).
"Baseband Marker 1/2/3"
Marker signal output for triggering and control of external devices with
user-definable marker signals.
"Baseband Sync Out/Baseband Sync In"
Signals available in enabled master-slave mode.
●
"Baseband Sync Out"
One or more outputs of a dedicated synchronization (and trigger)
signal, that has to be fed into the slave instruments.
●
"Baseband Sync In"
In the slave instruments, at most one input for the synchronization
(and trigger) signal.
Can be assigned to any global connector.
See also Chapter 8.3.1, "Connecting Multiple Instruments in Master-
Slave Mode", on page 428.
"BER Data", "BER Clock", "BER Data Enable", "BER Restart"
Option: R&S SMBVB-K80
Input signals for BERT/BLER testing.
"BER TestGen Data" , "BER TestGen Clock", "BER TestGen Data Enable", "BER Test-
Gen Restart"
Option: R&S SMBVB-K80
Output signals for BERT/BLER testing.
"Symbol Clock"
Output of the internal clock signal used for digital modulations. The
signal is generated automatically when the standard is switched on.
