Fig. 12-5 This circuit features a range from 1 Hz to 10 MHz with a linearity of 0.06%, and a typical full-scale drift of 50 ppm/℃. The zero-point error is about 0.2 μV/℃ (or 0.2 Hz/℃). To trim, ground the input and adjust the 1-Hz trim for 1-Hz output. Next, apply 10.000 V and adjust the gain trim for 10.000-MHz output. Repeat the procedure until both points are fixed.
