Patent ID: 8497792

Claim:
A signal generation system configured to generate a predetermined analog signal, the signal generation system comprising: a clock generator configured to generate, on the basis of an external clock signal, a predetermined clock signal; a signal generator comprising a first gain stage and a second gain stage configured to provide an overall gain of said signal generator, and output a stepped analog signal; an analog filter configured to filter said stepped analog signal output by said second gain stage, output said predetermined analog signal, and supply the predetermined analog signal to a device-under-test connectable to the signal generator; a first and a second clock mapping unit configured to receive said predetermined clock signal, and respectively supply, to said first and second gain stages, non-overlapped clock signals, wherein an amount of gain provided by said first and second gain stages is controlled by said non-overlapped clock signals; and a programmable band pass filter that is configured to receive output signals of the device-under-test.
