The V2802A LO Distribution Network has approxi4 dBm of nominal
gain across its range of operation. The M9311A Modulator module is highly
sensitive to excessive power levels at the LO input port. Therefore, be sure to
set the
option to true at initialization whenever
ExtLoDistributionUnit
the system is configured with an LO Distribution Network to prevent possible
damage to the module(s).
To enable the Shared Synthesizer functionality using the M9381A or M9391A Soft
Front Panel, set the following option in the Advanced Options field in the Connect
to Instrument dialog box:
ShareSynthesizerVisaSession=1
Additionally, as required, set the SynthesizerRole, SynthesizerOutputPort, and
ExtLoDistributionUnit (when using LO Distribution Network) options in the Advanced
Options field of the Connect to Instrument dialog box.
Initialization Process
When initializing the instruments you must first initialize the master, followed by all
the slaves. Similarly, when closing down the instruments you should reverse the
order – close all the slaves and close the master last. This helps ensure that the
“owner” of the synthesizer can cleanly initialize and shutdown the module.
The following is an example of a typical driver construction:
