E-Field Probe Calibration
Each probe needs to be calibrated according to a dosimetric assessment procedure with
accuracy better than ± 10%. The spherical isotropy shall be evaluated and within ± 0.25 dB. The
sensitivity parameters (NormX, NormY, and NormZ), the diode compression parameter (DCP)
and the conversion factor (ConvF) of the probe are tested. The calibration data can be referred to
appendix C of this report.
6.2. Data Acquisition Electronics (DAE)
The data acquisition electronics(DAE) consists of a highly sensitive
electrometer-grade preamplifier with auto-zeroing, a channel and
gain-switching multiplexer, a fast16 bit AD-converter and a command
decoder and control logic unit. AD-converter and a command decoder
and control logic unit. Transmission to the measurement server is
accomplished through an optical downlink for data and status
information as well as an optical uplink for commands and the clock.
The input impedance of the DAE is 200MOhm; the inputs are
symmetrical and floating. Common mode rejection is above 80 dB.

6.3. Robot
The SPEAG DASY system uses the high precision robots (DASY4: RX90BL; DASY5: TX90XL) type
from Stäubli SA (France). For the 6-axis controller system, the robot controller version (DASY4:
CS7MB; DASY5: CS8c) from Stäubli is used. The Stäubli robot series have many features that are
important for our application:
High precision (repeatability ±0.035 mm)
High reliability (industrial design)
Jerk-free straight movements
Low ELF interference (the closed metallic construction shields against motor control fields)
