Specification & Introduction
Definitions
Warranted specifications describe the performance of a model under stated operating 
conditions and are covered by the model warranty.
The following characteristic specifications describe values that are relevant to the use of the 
model under stated operating conditions but are not covered by the model warranty.
    • Typical specifications describe the performance met by a majority of models.
    • Nominal specifications describe an attribute that is based on design, conformance testing, 
        or supplemental testing.
Specifications are Warranted unless otherwise noted.
Textcal is the device temperature at last external calibration.
Tselfcal is the device temperature at last self-calibration.
 Conditions
Specifications are valid under the following conditions unless otherwise noted. Refer to each 
section for additional conditions that apply.
    • Self-calibration performed within the last 24 hours
    • Calibration interval of 2 years
    • 60 minutes warm-up time
 General
▷ ADC Linearity 
    0.5 ppm of reading + 0.5 ppm of range
▷ Effective Common-Mode Rejection Ratio (CMRR) (1 kΩ resistance in LO lead)
    >140 dB (DC), 100 ms aperture;
    >170 dB (>46 Hz) with high-order DC noise
    rejection, 100 ms aperture, typical
▷ Overrange
