Calibration Kits
1.1 Calibration Kit Normal Use
Calibration Kits are used as an accessory for VNAs to perform vector-error correction. Vector-error
correction is the process of characterizing systematic errors of the measurement system by
measuring known calibration standards, and then mathematically removing the effects of these
errors from subsequent measurements. The measurement accuracy of the calibrated VNA
depends mainly on the quality of the calibration kit used. Contributing factors are noise, linearity
and temperature stability of the VNA, transmission and reflection stability of a test port cable as
well as operator experience and care.
VNAs usually offer several techniques for correcting systematic measurement errors. The
standards in this calibration kit allow you to perform one-port OSL (OSM) or two-port OSLT
(TOSM) and TRM (TMR) calibrations from DC up to 6 GHz for measurements of Rosenberger
components with F 75
Ω
connectors.
Components with other F 75
Ω
connectors are mechanically compatible and can also be measured
if they are designed according to IEC 169-24 or EIA-550.
1.2 Warnings
The calibration standards of this calibration kit are mechanically sensitive devices. High
accelerations e.g. when falling down will damage them.
Connect the calibration standards only to test ports and other devices that have been cleaned and
checked for gauge, concentricity and integrity of the contact fingers. Detailed procedures are
described in Chapter 6 and 7.
Tighten the connector coupling nuts to the recommended torque with the torque wrench. Do not
over torque!
Consider the power applied to the Load calibration standards. Maximum power limits for the sum of
RF and DC power are defined in the specific data sheets.
It is good lab practice to use at least an ESD wrist strap when handling calibration standards or
DUTs on a VNA although the calibration standards themselves are not ESD sensitive. Please
consult your VNA manual.
Follow further limitations given in the specific data sheets.
Connect calibration standards and adapters of this calibration kit only to counterparts that
are designed according to IEC 169-24 or EIA-550. Incompatible connector dimensions will
damage them.
