Keysight/Agilent 3499C 9/14-Slot Switch/Control Mainframe
The Keysight/Agilent 3499C mainframe provides a scalable platform for large-scale automated test systems that require a substantial number of connections (signal routings) to instruments. It has 9 slot positions for plug-in modules, which are available in 1-slot, 2-slot, and 3-slot wide formats; they allow configuration combinations including DC multiplexing, RF switching, digital input/output, optical path management, etc.
The user may interface with the Switch/Control Mainframe either using its front panel for manual operation or by utilizing GPIB and RS-232 interfaces for remote operation. The fact that the mainframe supports all standard SCPI commands makes it easier to integrate with current software platforms. Additionally, the mainframe includes a 4-bit digital input/output port and capabilities for external triggering, along with memory to store up to fifty separate instrument setups. This allows users to easily modify their test sequences over time without having to add additional hardware.
Test engineers rely upon the 3499C as a centralized point to manage their signal distributions within both laboratory settings and high-volume manufacturing plants. Centralizing switching functions into a single mainframe enables test engineers to significantly reduce cable complexity and increase test throughput. Additionally, the mainframe can scan up to 350 channels per second and set 360 channels at once in less than .01 seconds. In particular, being able to use optical switch modules in combination with traditional electronic cards offers significant value when performing photonic component characterization and fiber optic network testing. These types of tests involve coordinating both light pathways and electrical bias signals. Furthermore, the high-density multiplexer modules provide additional support for such applications as semiconductor parametric testing, in-circuit testing, and data acquisition, which require numerous measurement points (hundreds).
In terms of long-term reliability and maintenance, the Keysight 3499C addresses these concerns by providing onboard relay cycle counters for each module. Each counter records how many times the relays have closed for each individual module; this information is used to predictively schedule maintenance as opposed to performing maintenance based upon reacting to failures. Additionally, since the architecture of the 3499C is designed to be modular, firmware upgrades can be loaded and installed as new measurements are needed, thereby protecting the original equipment cost. Overall, the Keysight/Agilent 3499C represents a reliable, portable, and easy-to-control switching hub that enables test engineers from industrial automation companies to develop robust test architectures that meet increasing demands from devices under test without redundant or unnecessary additions of multiple chassis or rewiring.
