Reinstatement of the NIST Field Strength Probe Calibration Service

Description

After recently completing a five year renovation, the NIST anechoic chamber for radio-frequency field strength measurements was returned to service. Tests of field probe transfer functions can now be performed from 10 kHz to 40 GHz. To validate that the chamber and measurement process maintained continuity, measurements of NIST field probes in the new chamber were compared with measurements in the chamber before renovation and in another test facility at NIST. An uncertainty analysis was carried out on the new measurement process.

0 X axis is the first column, distance from calibration position in mm.Y axis is the second column, the relative response of the probe vs the calibration position in dB.This file is the RF = 40 MHz trace. https://data.nist.gov/od/ds/mds2-2726/Fig3_AMTA_40GHz.csv
0 X axis is the first column, distance from calibration position in mm.Y axis is the second column, the relative response of the probe vs the calibration position in dB.This file is the RF = 500 MHz trace. https://data.nist.gov/od/ds/mds2-2726/Fig3_AMTA_500MHz.csv
0 X axis is the first column, RF frequency in MHz.Y axis is the second column, degree of equivalence in dB.Error bars are the third column, in dB.The first 6 rows are the 8 mm probes, the last 3 rows are the 6 mm probes https://data.nist.gov/od/ds/mds2-2726/Fig2_AMTA.csv
