NORMx,y,z are only intermediate values, i.e., the uncertainties of NORMx,y,z does not affect the E—field uncertainty inside TSL (see below ConvF). e NORM(Mx,y,z = NORMx,y,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 the stated uncertainty of ConvF. e DCPx,y,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 characteristics e Axy,zi Bxy.z Cxy,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. e Sensor Offset: The sensoroffset corresponds to the offset of virtual measurement center from the probe tip (on probe axis). No tolerance required. Certificate No: EX3—3665_May13 Page 2 of 11

There are no serviceable parts inside the DAE. Special attention shall be given to the following points: Battery Exchange: The battery cover of the DAE4 unit is closed using a screw, over tightening the screw may cause the threads inside the DAE to wear out. Shipping of the DAE: Before shipping the DAE to SPEAG for calibration, remove the batteries and pack the DAE in an antistatic bag. This antistatic bag shall then be packed into a larger box or container which protects the DAE from impacts during transportation. The package shall be marked to indicate that a fragile instrument is inside. E—Stop Failures: Touch detection may be malfunctioning due to broken magnets in the E—stop. Rough handling of the E—stop may lead to damage of these magnets. Touch and collision errors are often caused by dust and dirt accumulated in the Estop. To prevent Estop failure, the customer shall always mount the probe to the DAE carefully and keep the DAE unit in a non—dusty environmentif not used for measurements. Repair: Minor repairs are performed at no extra cost during the annual calibration. However, SPEAG reserves the right to charge for any repair especially if rough unprofessional handling caused the defect. DASY Configuration Files: Since the exact values of the DAE input resistances, as measured during the calibration procedure of a DAE unit, are not used by the DASY software, a nominal value of 200 MOhm is given in the corresponding configuration file. Important Note: Warranty and calibration is void if the DAE unit is disassembled partly or fully by the Customer. Important Note: Never attempt to grease or oil the E—stop assembly. Cleaning and readjusting of the E— stop assembly is allowed by certified SPEAG personnel only and is part of the annual calibration procedure. Important Note: To prevent damage of the DAE probe connector pins, use great care when installing the probe to the DAE. Carefully connect the probe with the connector notch oriented in the mating position. Avoid any rotational movement of the probe body versus the DAE while turning the locking nut of the connector. The same care shall be used when disconnecting the probe from the DAE. Schmid & Partner Engineering TN_BRO40315AD DAE4.doc 11.12.2009
