Atec FL7040-Kit User Manual
The FL7040 is a smart, fast, extremely accurate electric field probe that contains
an internal microprocessor to provide linearization, temperature compensation,
control, and communication functions. Noise reduction and temperature
compensation allow accurate measurements down to 2 V/m without zero
adjustment. Microprocessor based linearization technology provides a 54 dB
dynamic range. When rotated about its critical angle mount, the probe provides
typical isotropic response of ±1.5 dB to 40 GHz.
The FL7040 is laser powered to allow for continuous operation without
recharging or battery replacement.
Correction factors are provided with the probe. These factors can be loaded into
the Model FM7004 Field Monitor (sold separately) to automatically correct the
probe readings at user-specified frequencies. When correction factors are
applied, the true accuracy of the probe can be realized.
The FL7040 communicates through glass fiber optic cables, up to 100 meters
long, to the FI7000 interface. X, Y, Z, and isotropic readings can be returned
through an FI7000 in 20 msec.
NOTES: This probe requires an FI7000 for power and communication.
