Excess Noise Ratio expanded uncertainty (U(Y))
ENR values are given at cardinal frequency points over the frequency range of
each SNS series smart noise source. These values are stored within the noise
sources internal EEPROM and documented on the calibration report.
The uncertainty analysis for the calibration of the noise sources is in accordance
with the ISO/TAG4 Guide. The uncertainty data reported on the calibration report
is the expanded uncertainty (U(Y)) with 95% confidence level and a coverage
factor of 2. This uncertainty analysis is valid for APC 3.5 mm and Type-N
(Option 001) connector types.
[a] ENR values are given at cardinal frequency points over the frequency range of each noise source. These values are stored within the noise
source’s internal EEPROM and documented on the calibration report.
[b] Maximum change in complex reflection coefficient between source ON and source OFF at all frequencies for N4000A only: 0.01.
[c] For correct connector usage, refer
Table A-2 for the torque settings.
[d] Type-N connector (Option 001) only available on the N4000A and N4001A models.
[1] Characteristic values are met or bettered by 90% of instruments with 90% confidence.
