|TEST EQUIPMENT CALIBRATION - ISO 9001
We do traceable calibration of electronic test equipment valid for the ISO9001 quality system.
We keep secondary standards, checked against national standards (Italian SIT) for the following:
Voltage (DC e AC, 1mV to 10 kV)
Current (1uA to 1kA, DC and AC)
Frequency (up to 40 Ghz)
RF power (up to 40 GHz)
In particular, the frequency is maintained and distributed to the laboratories using two atomic standards (Cs and Rb), checked against the GPS satellite constellation. The accuracy reaches 3 parts in 10^12.
The reconditioned instruments can be delivered with ISO calibration if desired.
Then we specialize in calibration of EMC instruments. Those are calibrated with reference to national standards when possible, or to the applicable CISPR directive.
CALIBRATION LAB ACCURACY
Our calibration lab keeps the following incertitudes on measured values
For DC Voltage:
From 200 mV to1000V 2·10-5 + 0,5 mV
For AC voltage:
From 200 mV to 700V, 40Hz - 1 kHz: 4·10-4 + 5 mV
For DC Current:
From 0,1mA to10A 2·10-4
For AC Current:
From 200 mA to 2A, 40Hz - 1 kHz: 6·10-4
For DC resistance (10 Ohm<R<10 MOhm): 6·10-5
For DC resistance (100 mOhm<R<10 Ohm): 1·10-4
For frequency up to 40 GHz: 1·10-11
For RF power on 50 W, 7 mm line:
From 100 kHz to 5 GHz: 3%
From 5 GHz to 18,6 GHz: 5%
For RF power on 50 W, 3,5 mm line:
From 18 GHz to 40 GHz: 7%
AM modulation, carrier frequency up to 2GHz: 1,5%
FM modulation, carrier frequency up to 2GHz,
with deviation up to 300 kHz: 1,5%
