The FGD40 Function Generators series consists of three models. The FGD4024 and FGD4048 are packaged in a 2×2×0.395-inch case with internal DC/DC converters. The FGD4000 is packaged in a 2×1×0.395-inch case and requires a ±5Vout supply. All models provide DC, sine, square and triangular wave outputs; and all four functions are software selectable and programmable with 1.2Hz frequency and 2.44mV amplitude resolution. The 12-bit multiplying DAC can perform multiplication of any selected function with its input data code.
