The activity maintains one of the world's most comprehensive national capabilities for measuring electromagnetic quantities across the spectrum using established National Standards for Low Frequency AC Voltage & Current, Microwave Power, Attenuation & Impedance Standards along with the associated calibration facilities.
We regularly participate in BIPM and APMP key/Supplementary comparisons to establish mutual degree of equivalence with the corresponding standards of the leading NMIs and to ensure internationally recognised traceability of measurements. The CMCs registered in appendix C of BIPM-MRA has been reviewed in 2012.
Establishing traceability and providing apex level calibration services from 1 mV to 1000 V in the frequency range of 10 Hz to 1 MHz with uncertainty from ± 10 ppm to ± 1000 ppm
Providing traceability along with calibration services from 1 mA to 10 A in the frequency range of 40 Hz to 10 kHz and 20 A upto 5 kHz with uncertainty from ± 20 ppm to ± 100 ppm.
Traceability of high frequency thermal voltage converters against the primary standard of HF voltage based on calorimetric principle has been established in the voltage range from 1 mV to 50 Volt upto 1000 MHz with ±1.2 % uncertainty.
Providing apex level calibration services and dissemination of standards for maintaining the traceability in power measurements upto 10 mW in the frequency range of 1 MHz to 18 GHz with uncertainty upto ± 1.5 %.
Establishing traceability in attenuation using 30 MHz WBCO attenuator and providing apex level calibration services from 0.05 dB to 60 dB at 30MHz, 1GHz to 18 GHz with uncertainty of ±0.02 dB/10 dB.
Providing apex level calibration services and dissemination of standards for maintaining the traceability in impedance(reflection coefficient/VSWR) measurements in the frequency range 2 GHz to 18 GHz, in coaxial with uncertainty of ±0.02 in VSWR and in the frequency range 5.8 GHz to 18 GHz in waveguide with uncertainty of ±0.002 to 0.004 in reflection coefficient magnitude.
