Modules

The 34980A implements a superior selection of switch topologies. The 34980A switch topologies are similar to 3499A/B/C switch modules and include multiplexers, matrixes, high-power, general purpose, and RF/microwave switches. However, the 34980A modules have utilized the newest switch technology which enables a higher density of channels per module, and the ability to achieve the faster scan rates with the integrated DMM. The 34980A offers other functionality used in test systems and includes digital I/O, a counter/totalizer and D/A converters. New 34980A functions include a FET

multiplexer switch module, a counter/timer and digital I/O with pattern generator/detector along with digital I/O and D/A converters. The 34980A RF and microwave switch drivers offer functionality for a broader range of RF/microwave switches being used by customers today.

The 3499A/B/C does provide a selection of optics switching which is not available with the 34980A. Table 2 shows the

34980A and 3499A/B/C system modules organized by switch and/or measurement type. It is easy to compare and upgrade from the 3499A/B/C switch modules to the new 34980A switch modules as well as add new switch, measurement and control capabilities.

Benefits of the new 34980A modules vs 3499A/B/C modules

•Increased channel count per module with the same switch reliability

•Increased drivability for various RF/uWave switches

•High Speed FET multiplexer

•Reed Matrix switch

•Switch/attenuator driver

•Counter/Timer

•High Speed Digital I/O with memory

•Analog output with waveform capabilities

•Breadboard module with +5V, +12V

With so many different types of switch modules to choose from, you can easily identify the modules from Table 2 that provide the best solution to meet your test application needs.
