The 290 has two modes, low-voltage (collector voltage 0 to 30 V) and high-voltage (collector voltage from 0 to 100 V). The fixture's input and output are 50 Ω GR-874 connectors, so it can be used with standard cables and test instruments while maintaining good signal integrity. The instrument itself is rated to have a risetime of under 1 ns.
