Figure 5. Multiplying Circuit Offset Adjust
Procedure
1. Set all trimmer pots to 0V on the wiper.
2. Connect VX input to ground. Put in a full scale square
wave on VY input. Adjust XOS(R5) for no square wave
on V0 output (adjust for 0 feedthrough).
3. Connect VY input to ground. Put in a full scale square
wave on VX input. Adjust YOS(R9) for no square wave
on V0 output (adjust for 0 feedthrough).
4. Connect VX and VY to ground. Adjust VOS(R16) for 0V
on V0 output.
