Access:
► Select "SGMA-GUI > Instrument Name > Connector".
Comprises the settings necessary to configure the signal at the input/output of the
multi-purpose "TRIG" connector.
Trigger Connector Mode
Determines the signal at the input/output of the multi purpose [TRIG] connector.
"Signal Valid"
Output of high signal to mark valid frequency and level settings.
"Not Signal Valid"
Output of high signal to mark the transition state when frequency and
level change.
"Pulse Video Out"
Output of the internally generated pulse video (modulating) signal.
The video signal level corresponds to the RF envelope.
"Pulse Mod Ext Trigger"
Input for an external trigger signal, used to trigger the pulse genera-
tor.
"Pulse Mod Ext Source"
Input for an externally provided pulse modulation signal.
Used when an external pulse modulator source is provided at the
connector.

9.8 I/Q modulation and signal impairment
The R&S SGS offers I/Q modulation with external analog I/Q signals. I/Q modulation
with an external analog I/Q signal is possible for the instrument equipped with fre-
quency options R&S SGS-B106V/-B112V. The external signal is input via the I and Q
connectors and transferred to the I/Q modulator.
Before the signal is fed into the I/Q modulator, the signal can be impaired. Impairment
at this point along the signal flow is provided for error correction of the supplied signal
or for enabling dedicated impairments. Impairments caused by the I/Q modulator are
automatically corrected by the "Internal Adjustments" function.
