300 MHz 32×8 PXI and PXIe modules

Pickering Interfaces has introduced new PXI RF matrix ICs with a 32×8 topology, representing a 33% increase in matrix density per chassis slot.

The new 40-724 PXI & 42-724 PXIe compact footprint modules offer high performance with a usable bandwidth of 300 MHz for non-loop-thru models.

Facilitating simple scalability, the modules have options with loop-thru ports on the Y-axis for larger applications requiring matrix expansion.

To provide maximum granularity of test system construction, the 4x-724 family is available in four matrix sizes: 16×4, 16×8, 32×4 and the fully populated 32×8.

Loop-thru enabled options are provided for each matrix size.

The loop-thru ports are connected directly to the matrix, which, unlike other RF matrix products, allows the creation of X-to-X signal paths between boards when cascading multiple modules.

This useful feature increases the flexibility of the test system but with reduced RF performance.

The 4x-724 RF matrix modules are equipped with high-quality ruthenium-sprayed reed relays, ensuring a long service life.

In addition, reed relays have an operating time of only 0.5 ms (typical), which is significantly less than electromechanical solutions, minimising test cycle time and increasing product test productivity.

The modules are available with a PXI or PXIecontrol interface, offering flexibility in chassis selection.

All versions use standard SMB connectors to maximise system performance while simplifying the interface to external instrumentation and DUTs.

The new 4x-724 RF matrix modules are intended for general RF testing in many applications, including emergency radio and semiconductor testing.

All versions of the 4x-724 are supported by Pickering's eBIRST switching system test tools, which can be used for preventive maintenance tests to determine whether relays are approaching the end of their life cycle.

In addition, eBIRST tools allow rapid troubleshooting, thus minimising system downtime.

Pickering's connection division offers standard and customised cable solutions that can help with the integration of the module into the test system.

Comments

Commented Steve Edwards, Switching Product Manager at Pickering Interfaces: "The family builds on Pickering's existing RF matrix module technology to increase the maximum matrix size to 32×8 for use in 50 Ω test applications. The higherdensity, which represents a marked increase over existing products, allows complex switching systems to be manufactured while requiring only two slots per chassis."
