CFG280 11 MHz Function Generator with Counter

The CFG280 combines an 11 MHz function generator with a 1 Hz to 100 MHz frequency counter. The on-board counter allows the operator to set the frequency output of the function generator precisely. This versatile instrument conserves both bench space and budget.
