Assign External Instrument

To open the Assign External Instrument dialog, click the down arrow on an unassigned external instrument block.

 

The Assign External Instrument dialog will appear.

 

Assign

Instrument

Lists the names of all available instruments that can be assigned to the external instrument block.

For best performance, external instruments connected to PXB should have the same options and the same firmware revision. Mixing different models of analyzer or source, mixing options within those products, or mixing firmware revisions within those products will cause small latency differences between the channels. This can lead to unexpected degradations in the measurement's results.

 

Latency compensation is performed such that combinations of X-Series Signal Generators (MXG-A, MXG-B, EXG-B) are now supported for both SISO and MIMO configurations. Combinations of X-Series Signal Generators and the ESG-C are not allowed in MIMO configurations. ESG-C is allowed in combination with X-Series Signal Generators for SISO configurations only and latency compensation is performed.For signal analyzers, the dependency is on the installed options rather than model number. For MIMO configurations, PXA/MXA/EXAs with RTL can be mixed and PXA/MXA/EXAs without RTL can be mixed, but the instruments must all either have RTL or not. Signal Analyzers used in MIMO configurations should be running the same firmware version for best performance. For non-MIMO configurations, the PXB allows mixing but warns the user about the different latencies.

To

IO Port Name

Lists all available I/O ports at the rear panel that the external instrument may be assigned.

IO Port Type

Lists the two types of I/O port connections available for the externally connected instruments.

Digital

uses the PXB's digital I/O bus to connect to the external instrument.

Analog

uses SMB(f)-to-BNC(m) cables to connect the PXB's analog I/Q connectors to an RF signal generator capable of receiving analog I/Q inputs
