an internal microprocessor to provide lineariza-
tion, temperature compensation, control, and
communication functions. Noise reduction and
temperature compensation allow accurate meas-
urements without zero adjustment.
The probe is laser powered to allow for continu-
ous operation without battery recharging or re-
placement. It communicates and is powered
through glass fiber optic cables, up to 100 me-
ters long, connecting to the FI7000 interface. X,
Y, Z, and isotropic readings can be returned
through an FI7000 in 20 msec.
The PL7004 extends the range of AR laser pow-
ered E–field probes to use in measuring peak
pulsed electric fields. Response-smoothing time
constants provide consistent readings for pulse
rates as low as 200Hz, approximately 1 second
after an input change.
This probe requires an FI7000 for power and
communication. FM7004A is recommended
for local monitoring and control.
The PL7004 is designed specifically for use in
measuring pulsed electric fields found in radiat-
ed immunity testing (for example, automotive
radar pulse tests General Motors GMW3097
and Ford ES-XW7T-1A278-AC). The probe is
calibrated to measure the RMS level during the
ON time of a pulsed electric field.
Correction factors are provided with the probe.
These factors can be loaded into the Model
FM7004A Field Monitor (sold separately) to au-
tomatically correct the probe
readings at user-specified fre-
quencies. When correction
factors are applied, the true
accuracy of the probe can be
realized.
This probe is NOT designed to
respond to CW fields. AR offers
an extensive line of field
probes for CW measurement.
This is a smart, fast, extremely
accurate pulsed electric field probe that contains
