0907DS-TEM Cell
Fischer Custom Communications, Inc.
offers a family of Transverse
Electromagnetic (TEM) cells that can be
used for both emissions and immunity
testing.
The patented septum design offers broad
frequency response, excellent field
uniformity, low VSWR and low insertion
loss. Models FCC-TEM-JM1 and FCC-TEM-JM2
are ideal for radiated emission testing of
semiconductor devices according to SAE
1752/3
The JM series TEM Cell can be used for
immunity testing and require less than 3.7
milli-watts input power to achieve a 10 volt
per meter electric field and 37 watts to
achieve 1000 volt per meter electric field.
