Note: The laser
driver in the HI-6100
Field Monitor also
incorporates this safety
interlock mechanism,
and operates in the
same manner.

LASER-POWERED FIELD PROBES
The HI-61XX Series LaserPro™ Field Probe is a laser-powered probe, an
excellent tool for electric field mapping, industrial monitoring, and EMC
field measurements.
The HI-61XX Series probes contain a photo-voltaic converter that provides power
to the probe circuitry when sufficient light power is received by the converter.
The light power is generated by a laser in the HI-6113 Laser Data Interface, and
is transmitted to the converter through an optical fiber in the duplex fiber optic
cable. The probe communicates with the HI-6113 through this fiber optic cable.
Receiving power from the HI-6113 allows for unlimited test times.
The probe system incorporates a safety interlock mechanism that turns off the
laser if the HI-6113 does not receive data from the probe within a specified time
frame. The safety mechanism is intended to prevent injury from the laser if the
HI-6113 issues a command to turn on the laser while the fiber optic cables are
disconnected, improperly connected, cut, or damaged.
The HI-6100 Field Monitor may be used with the HI-61XX Series for RFI/EMC
testing. The HI-61XX Series can also be connected to a personal computer using
an optional HI-6113 Laser Data Interface and ProbeView™ Laser software.
HI-6122 Electric Field Probe
The ETS-Lindgren HI-6122 Field
Probe provides broadband
frequency coverage and wide
dynamic range that satisfies the
demands of most test requirements.
The frequency response of the
HI-6122 is 10 kHz to 1 GHz, and the
dynamic range is 2 to 800 Volts per
meter (V/m).
The HI-6122 is a true 3-axis probe. When requested, X, Y, Z, and total field
data can be reported.
