NORMx,y,z are only intermediate values, ie., the uncertainties of NORMx,y,z does not affect the E*—field uncertainty inside TSL (see below ConvF). * NORM(Mxy,z = NORMxy,z * frequency_response (see Frequency Response Chart). This linearization is implemented in DASY4 software versions later than 4.2. The uncertainty of the frequency response is included in thestated uncertainty of ConvF. * DCPxy,z: DCP are numerical linearization parameters assessed based on the data of power sweep with CW signal (no uncertainty required). DCP does not depend on frequency nor media. * PAR: PAR is the Peak to Average Ratio that is not calibrated but determined based on the signal characteristios * Axy,zBuy.z Cuy.z; Dxy,z; VRxy,z: A, B, C, D are numerical linearization parameters assessed based on the data of power sweep for specific modulation signal. The parameters do not depend on frequency nor media. VR is the maximum calibration range expressed in RMS voltage across the diode. * ConvF and Boundary Effect Parameters: Assessed in flat phantom using E—field (or Temperature Transfer Standard for f < 800 MHz) and inside waveguide using analytical field distributions based on power measurements for f > 800 MHz. The same setups are used for assessment of the parameters applied for boundary compensation (alpha, depth) of which typical uncertainty values are given. These parameters are used in DASY4 software to improve probe accuracy close to the boundary. The sensitivity in TSL corresponds to NORMx,y,z * ConvF whereby the uncertainty corresponds to that given for ConvF. A frequency dependent ConvF is used in DASY version 4.4 and higher which allows extending the validity from + 50 MHz to + 100 MHz. * Spherical isotropy (3D deviation from isotropy): in a field of low gradients realized using a flat phantom exposed by a patch antenna. * Sensor Offset: The sensor offset corresponds to the offset of virtual measurement center from the probe tip (on probe axis). No tolerance required. * Connector Angle: The angle is assessed using the information gained by determining the NORMs (no uncertainty required).

Methods Applied and Interpretation of Parameters * DC Voltage Measurement: Calibration Factor assessed for use in DASY system by comparison with a calibrated instrument traceable to national standards. The figure given corresponds to the full scale range of the voltmeterin the respective range. * Connector angle: The angle of the connectoris assessed measuring the angle mechanically by a tool inserted. Uncertainty is not required. * The following parameters as documented in the Appendix contain technical information as a result from the performance test and require no uncertainty. * DC Voltage MeasurementLinearity: Verification of the Linearity at +10% and —10%of the nominalcalibration voltage. Influenceof offset voltage is included in this measurement. * Common mode sensitivity: Influence of a positive or negative common mode voltage on the differential measurement. * Channel separation: Influence of a voltage on the neighbor channels not subject to an input voltage. * AD Converter Values with inputs shorted: Values on the internal AD converter corresponding to zero input voltage * Input Offset Measurement: Output voltage and statistical results over a large number of zero voltage measurements. * Input Offset Current: Typical value for information; Maximum channelinput offset current, not considering the input resistance. * Input resistance: Typical value for information: DAE input resistance at the connector, during internal auto—zeroing and during measurement. * Low Battery Alarm Voltage: Typical value for information. Below this voltage, a battery alarm signal is generated. «_ Power consumption: Typical value for information. Supply currents in various operating modes.
