Math Functions
The 3458A performs the following
math functions on measurements:
null, scale, offset, rms filter, single pole
filter, thermistor linearization, db, dbm,
% error, pass/fail LIMIT TESTING, and
statistics. Two math functions may be
used at one time.

One-year specifications for NPLC 100 within 24 hours and ±1ºC of last ACAL, Tcal ±5ºC, MATH NULL, fixed range.
Add 2 ppm of reading additional error for Agilent factory traceability of 10 V DC to US NIST. Traceability error is
the absolute error relative to National Standards associated with the source of last external calibration. Transfer
specifications for NPLC 100, following 4-hour warm-up. Full scale to 10% of full scale. Measurements on the
1000 V range are within 5% of the initial measurement value and following measurement settling. Tref is the
starting ambient temperature. Measurements are made on a fixed range using accepted metrology practices.
