SPEAG takes another decisive technological
leap forward with the introduction of our new

time domain sensor (TDS) probes: miniatu-
rized electrically fully isolated active optical
magnetic or electric field sensors operating
in the 10 MHz to 6 GHz frequency range.
Our TDS technology facilitates measure-
ments in both frequency, and time domains,
while maintaining complete amplitude and
phase information of the measured signal
with unparalleled sensitivity and spatial
resolution. A TDS system consists of a

TDS electric or magnetic field probe with

a remote unit to provide the power-over-
fiber source for the sensors in the forward
link and convert the RF-over-fiber reverse
link for direct connectivity to standard RF
measurement equipment. All TDS sys-
tems are calibrated in SPEAG’s calibration
laboratory (ISO17025 for TDS pending).

Applications
Antenna/Microwave
TDS probes are unique tools for the analysis of antenna
problems and microwave components, such as near-
field characterization of MIMO systems and phased-array
structures, performing near-to-far-field transformations as
well as reconstruction of complex EM sources.

EMC/EMI
TDS probes are the first probes capable of providing full
electrical isolation of the sensor element while maintaining
unparalleled sensitivity, making them perfect for module-,
board-, and chip-level EMI/EMC scanning, sniffing, and
analysis.
MRI
TDS probes are fully compatible with the MRI environment,
allowing application, for example, for mapping complex
vectorial B1-field distributions or phase and amplitude
distributions along implants exposed to EM fields during
MRI.
