VSG #2: M9381A
M9214A in slot 2
M9301A in slot 3
M9350A in slot 4
M9214A in slot 6
M9301A in slot 7
M9350A in slot 8
M9300A in slot 10
M9311A in slot 11
M9310A in slot 13
M9301A in slot 14
M9311A in slot 15
M9310A in slot 17
M9301A in slot 18
Other module and instrument placements can be used, but this configuration
optimizes speed and makes cabling simpler for phase coherent configuration.
The M9300A PXIe Frequency Reference module must be installed in slot 10 for
proper time synchronization between instruments. For more information, see
.
Sharing the M9300A Frequency Reference
Cabling is different for time-synchronization-only (independent LO) configuration
and phase-coherent (shared LO) configuration. See the following sections for
cabling information.
Time-Synchronized, Multi-Channel PXIe VSA & VSG (Independent LO)
When phase coherence is not required, cable the instrument as follows for time
synchronized multi-channel operation for independently tunable channels.
2x2 Independent LO Cable Connections:
– Primary 100 MHz connection (8121-2175, long SMB-SMB)
– Secondary 100 MHz and IF connections (8120-5091, short SMB-SMB)
– Semi-rigids
Phase-Coherent, Multi-Channel PXIe VSA & VSG (Shared LO)
When the carrier phase must be aligned between channels (beamforming, relative
phase measurements), cable the instrument as follows:
2x2 Shared LO Cable Connections:
