On-site evaluation and EMC measuring instrument calibration, batch calibration

PDF Total evaluation / Calibration for chamber and EMC measurement equipments(PDF: 206KB)

EMC measuring instrument and calibration of antennas by positive system NIST traceable that receives audit from US A2LA. It makes on-site for the customer's place (Available even at holiday/ midnight), and NSA of the chambers/ The periodical calibrations such as modification coefficients and the immunity examination machines of evaluation of characteristics, improvement consulting for SVSWR.

Calibration of Antenna

1. Bi-con for EMI measurement/ LPD/ Bi-Log antenna: 30MHz-2GHz

ANSI C63.5 (2006) US Liberty Lab which derive the free space factor. The comparison calibration with the standard antenna calibrated by three antenna method is done on a standard at the open site of US Liberty Lab.

  • The free space antenna factor, the factor calibration by and each height, The factor for SAE automotive equipment(D=1.0m/h=3.0m) factor.
  • NSA measurement factor: D=10m/3m and h=1.0/ 1.5/ 2.0m, Horizontal/ Vertical: The data is offered in customer's measurement frequency steps.

Open suite of Liberty Lab. USA

The repeatability of the antenna factor thought a year.

2. Horn antenna: 1GHz-40GHz

The comparison calibration with three antenna method or a standard antenna on floor absorber as free space condition.

  • Antenna factor: We offer D=3.0/1.0m sweep method detailed calibrated value
  • VSWR: To confirm for the connector change by aging variation.
  • Radiation Pattern: 2°/0.5GHz steps data offer. To confirm change in shape of the antenna.
*
1 and 2, It is also available the comparison calibration with our standard antenna at customer's site.

3. Loop antenna: 10Hz-9KHz-30MHz IEEE Std. 291-1991 standard magnetic field method magnetic field factor:

  • AFH and magnetic field strength factor: AFpT and electric field factor: AFE

4. Loop sensor for MIL examination: 10Hz to 1MHz Center magnetic field method by NIST

5. POD for SVSWR measurement: 1GHz to 18GHz The calibrated at free space condition

  • Radiation pattern: Compliant with CISPR 16-1-4
  • Antenna factor: D=3.0m and over 1GHz NSA evaluation of the measurement is also available.
  • VSWR: Confirming with variation of connectors.



Calibration for Electric Field Sensor

Compliant with IEEE Std 1309 (2005), IEC61000-4-3 Ed3, The comparison calibration with the standard equipment traced by NIST.
