Additional Features: Dual 4-Channel RF Multiplexer 2 GHz bandwidth, 75 Ohm BNC to SMB adapter cables included The Agilent 34906A offers broadband switching capabilities for high-frequency and pulsed signals. Use it to route test signals between your device under test and your signal generator, oscilloscope, spectrum analyzer, or other instrumentation. The RF multiplexers are arranged as two independent 1 x 4 multiplexers, each with a common shield and a switched center conductor. Connections can be made directly to SMB inputs with 2 GHz usable bandwidth, or to the BNC-to-SMB adapters provided with 1 bandwidth. Multiple banks may be cascaded together for applications requiring even larger topologies--create a stubless 16:1 multiplexer in a single frame.
