S-parameters, insertion loss, return loss, coupling factor, directivity and amplifier gain of RF components calibrated on site under LAB Support Ltd.'s A2LA accredited ISO/IEC 17025 scope.
Every radiated and conducted emission result subtracts a cable loss, and every immunity system relies on coupler and attenuator values to set forward power. These corrections drift with connector wear and cable flexing, so the components are calibrated on a schedule. All of them are covered under one S-parameter capability from 5 Hz to 40 GHz.
| Parameter | Range | Common methods and standards |
|---|---|---|
| Transmission S21/S12, magnitude and phase | 5 Hz to 40 GHz | Network analyser with calibration kit |
| Reflection S11/S22, magnitude and phase, VSWR | 5 Hz to 40 GHz | Network analyser with calibration kit |
| Attenuators and RF cables, insertion loss | 9 kHz to 40 GHz | Network analyser, substitution |
| Directional couplers, coupling and directivity | 9 kHz to 40 GHz | Network analyser |
| Amplifiers and preamplifiers, gain | 9 kHz to 40 GHz | Network analyser, power meter |
The methods and standards shown are the ones most commonly requested. Within each parameter and range listed on the accredited scope, other calibration methods and standard editions can be supported under the flexible-scope provisions of LAB Support's A2LA accreditation. The measurement uncertainty for each parameter is stated on the certificate. Field calibration is included in the scope for every line above.
From our own calibration records. Any instrument within the scope can be calibrated; these are the ones we see most.
N, SMA, 3.5 mm, 2.92 mm, 2.4 mm, BNC and 7/16 with the corresponding calibration kits. Tell us the connectors and adapters you use so the right kits come.
Yes. Amplifier gain and flatness are measured at the drive levels you use, and the coupler and power sensor in the same path are calibrated at the same visit.
The certificate tabulates insertion loss at the frequencies you specify. Data files for BAT-EMC, Compliance Test Studio and EMC32 correction tables can be supplied on request.
Malaysia, Singapore and Vietnam, with Penang as the base. Other locations on request.
