DUAL-OUTPUT RF SIGNAL SOURCE for field service applications. The NovaSource X2 is a programmable RF signal generator that combines the functionality of two individually controllable signal sources into a convenient package. Models are available in bands from 45 MHz to 2.5 GHz, with various step sizes. Once set to an exact frequency, nonvolatile memory allows the unit to be used repeatedly in the field or lab without being reprogrammed.--Nova Engineering
