3. OPERATION
This section discusses the theory of operation and the functions
of the HI-4453/FP5083/FP4083/FP2083 Isotropic Electric Field
Probe. A high-level block diagram (Figure 3) is included to aid
the discussion. The objective is to provide information
enhancing user understanding of the design of this probe.
SYSTEM THEORY
The HI-4453/FP5083/FP4083/FP2083 Broadband Isotropic
Electric Field Probe utilizes a microprocessor for intelligent
operation and control. The probe's self-contained power supply
employs a 3.6 VDC NiCd battery, which provides up to 17 hours
of continuous operation.
For each axis, the probe measures the radio frequency signal
level and generates a linearized reading of the measurement.
The result is transmitted to the readout over glass fiber optic
cables. See "Probe Operation" for a more detailed explanation
of the functioning of the HI-4453/FP5083/FP4083/FP2083.
The probe relays data to the readout via either a short form or
long form output word. See Appendix B for details on both
output word formats.
For some applications, you may use a computer with an RS232
serial port to communicated directly with the HI-
4453/FP5083/FP4083/FP2083 via ETS-Lindgren’s optional HI-
4413P Fiber Optic/RS232 Interface.
