Theory of Operation
Multiplying DAC
The dc voltage from the detector is applied to an 8-bit multiplying DAC; the
multiplier is a digital input from the 8510C, and is used to apply correction
factors to the detector voltage.
Correction factors are needed because of (1) imprecision in the step
attenuators, and (2) variations in RF power across the frequency range of the
8510XF. These issues are discussed under “Level Calibration” on page 5-18.
