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