EMSense™ 40
ETS-Lindgren’s EMSenseTM 40 10 MHz to 40 GHz Electric Field Probe is versatile and ideal for various military, commercial and automotive specifications.
ETS-Lindgren's
laser-powered EMSenseTM 40 Electric Field Probe embodies the latest
innovations in isotropic sensor design, low noise and miniaturized electronics.
Designed to be single range reading, the EMSense 40 can read data continuously
over the entire dynamic range. Data values for each axis (X, Y, and Z) can be
read individually or summed. Fiber optic signal and power lines link the RF
field probe to either the EMCenter 2/7 Slot, or as a direct connect to a PC USB
port with the EMCenter 1-Slot.
The EMCenter 2 and 7
Slot Modular RF Platform along with the EMSense 40 interface card can be used
as a Field Monitor in addition to its capability as a system level platform.
The EMCenter 1-Slot
with the EMSense 40 interface card provide laser power and communications for
the EMSense 40 Field Probe. A USB connection to the PC allows for quick and
easy data collection, using ProbeView V software.

The EMSense 40 probe
utilizes an updated CPU in the EMCenter to support its improved communication
speed. Some EMCenter units carry an older CPU that must be upgraded to support
the EMSense 40 probe and plug-in card. To check compatibility, access the
" Info" menu on the EMCenter main screen and check
slot 8. The compatible processor is 7000-008. If the EMCenter shows processor
7000-007, a processor upgrade is available through the ETS-Lindgren service
center.
Alternatively, a
stand-alone EMCenter is available for EMSense 40 that appears as an additional
EMCenter slot to EMC control software.
