8x8 M9391A and M9381A Instrument Connections
A set of 8-channel M9381A PXIe VSGs installed in two M9018/M9019A 18-slot
chassis and a set of 8-channel M9391A PXIe VSAs installed in another pair of
M9018/M9019A 18-slot chassis can be configured for multi-channel testing by
using a single (M9036A or M9037A) embedded controller, M9021A PCIe cable
interface modules (6 with M9036A and 5 with M9037A) and 3 PCIe cables to
connect the four chassis. Each chassis has its own M9300A PXIe Frequency
Reference that is shared by all the instruments in that chassis. The M9300A PXIe
Frequency Reference must be installed in slot 10 of each chassis. For
recommended configuration, the 10 MHz reference signal for each pair of chassis
(containing 8-channel M9381A or 8-channel M9391A) is provided by the M9300A
in the master chassis from the OCXO Out connector. Alternatively, you can use an
external 10 MHz reference signal. For recommended configuration, the OCXO
output is split and distributed to the two Reference modules using equal length
cables, as shown below. It is critical to synchronize chassis within each chassis
group if timing and/or phase synchronization is important to your measurements.
