Keysight/Agilent M9161D PXI Solid State Dual SP4T Switch Module
Designed for applications requiring high frequency, high density, and reliability in signal routing, the Keysight M9161D is a PXI-based solid-state switch module housed within one PXI slot. The M9161D contains two independent SP4T solid-state switches covering frequencies from 50 MHz to 20 GHz. The M9161D's semiconductor architecture provides an unparalleled number of cycles of switching performance as well as consistent 60 μs typical switching speeds, allowing for years of continuous, trouble-free operation in automated test environments. The M9161D has an isolation level of 100 dB @ 9 GHz and an average of 120 dB of isolation on the Com1-Com2 port; therefore, the module can effectively reduce crosstalk levels in high-density ATE systems for communications and aerospace/defense applications. The wide range of frequencies allows the module to be used for both low-frequency RF testing and pre-compliance MMW testing.
The M9161D also integrates easily into PXI, PXI Hybrid, or CompactPCI chassis. The module draws very little current from the backplane. In addition to providing high levels of isolation, each of the RF paths has controlled insertion loss characteristics. For example, insertion loss values vary from 0.564 f + 2.359 dB maximum from 250 MHz to 10 GHz. Return loss and power handling specifications are defined for each port, allowing users to determine how much signal integrity they can expect within their test setup. As a solid-state switch, there are no mechanical components that move during operation of the device. Combined with the extremely long cycle life of the M9161D, this results in a lower total cost of test over time.
The M9161D includes IVI-compliant drivers for Windows and LabVIEW along with a graphical soft front panel for manual configuration of the switching matrix. There are several code examples available for use, including LabVIEW, LabWindows/CVI, Visual Studio (C, C++, C#), and MATLAB, to accelerate software development for custom automation and test sequencing. The typical video leakage of the M9161D is 470 mV, while the settling time is less than 120 microseconds to better than 0.01 dB at 10 GHz, making the module ideal for high throughput testing of wireless devices, semiconductors, and aerospace components. Together, these attributes provide the user with a versatile building block that may be incorporated into any automated RF test system.
