Abstract :
The paper describes frequency dependence correction of the Agilent 3458A DMM in DCV sampling mode. The biggest error source identified is the input filter roll-off, which was measured and evaluated with an asynchronous sampling technique using phase sensitive sine fit algorithm. Corrected response is flat within 50 μV/V in the whole audio frequency band.
