A.H. Systems Injection Current Probe Series

GENERAL INFORMATION

INTENDED PURPOSES
This equipment is intended for general laboratory use in a wide variety of
industrial and scientific applications, and designed to be used in the
process of generating, controlling and measuring high levels of
electromagnetic Radio Frequency (RF) energy. It is the responsibility of
the user to assure that the device is operated in a location which will
control the radiated energy such that it will not cause injury and will not
violate regulatory levels of electromagnetic interference.
GENERAL DESCRIPTION
The current probe fixture is composed of an electrically short section of
trough transmission line. The short section permits the measurement of
current in the center conductor of the line, while the current probe is
clamped around the center conductor. The fixture's output terminal is
terminated in a 50 receiver, spectrum analyzer or RF voltmeter. A
measurement of the voltage developed by this RF voltmeter permits the
calculation of current flowing in the center conductor. The trough is large
enough to permit the current probe to be clamped around the center
conductor, with the outer conductor of the trough extending around the
current probe's outer shield.
A mechanical outline of the fixture and a typical injection probe mounted in
the fixture is shown in Figure 1. This fixture is useable over the frequency
range of 10 kHz to 400 MHz.
BROADBAND CURRENT PROBES (MONITOR PROBES)
During the equipment test a broadband current probe (monitoring probe) is
clamped around the same wire or wire bundle that the injection probe is
clamped around. The broadband current probe shall be calibrated for the
test frequencies and cable of operating with 1 ampere of RF current. The
broadband current probe shall be located approximately 5 cm from the
injection current probe.
INJECTION CURRENT PROBES
Injection current probes must be capable of injecting the specified current
levels into the circuit under test. Each probe has its own technical
description and model number, and each has its own individual technical
literature.
