Keysight Technologies Inc. has uncloaked a 50GHz frequency extension to the M9393A PXIe performance vector signal analyser (VSA) to offer frequency coverage previously unseen in modular instrumentation. The M9393A supports Ka-band frequencies and beyond, and claims to deliver Keysight's mm-wave measurement technology in a PXI form factor for manufacturing and design validation of modems, transponders and sub-components for commercial and military satellite communications, stated the company.

The innovative design of the M9393A offers engineers the ability to validate the performance of Ka-band designs with continuous frequency sweeps from 3.6GHz to 50GHz (option FRX) and direct access to 800MHz of IF bandwidth (option WB1). With displayed average noise level (DANL) better than -155dBm/Hz at 40GHz and accelerated sweep speed, the M9393A provides the fastest low-level spur searching capability on the market, boasted Keysight. The compact, modular form factor allows for dual channel configuration in a single chassis for increased measurement density and time synchronous multi-channel radio frequency measurements.

The M9393A's extremely low noise floor in Ka-band, combined with Keysight's 89600 VSA software enables measurements of 20GHz of spectrum with -110dBm DANL, in less than 10s, for the fastest measurements of low-level harmonics and spurs. This fundamental test is not only a regulatory requirement, it is a key indicator of system performance, and often a bottleneck in testing. In the past, this measurement has required the test engineer to trade-off coverage and time, with tests taking minutes to hours. The M9393A's frequency sweep speed eliminates this trade-off and allows developers to track minute signal distortions that were previously not practical to examine.

Upgradeable capability, including frequency, analysis bandwidth, number of channels and memory, allows engineers to quickly adapt to changing test needs, reducing overall cost of test. The extensible modular architecture of the M9393A allows for easy addition of the M9169E PXI-h switchable input programmable attenuator module, recommended for low noise, high reliability power control up to 50GHz. The M9169E also enables automatic routing of the M9393A's built-in calibrator signal, improving amplitude accuracy and uptime.

The M9393A with options FRX and WB1 are available for order, with prices starting at $77,000. The M9169E is available for order, starting at $12,000.
