手动横向电磁波箱TC-5062C简介

TC-5062C 6 GHz TEM Cell

TC-5062C, 6

GHz TEM

Cell generates the

Electro-Magnetic field

for testing small

RF devices

such

as

wireless communication receiver,

Mobile phone,

etc.

An external

test

signal

applied

through

the

input port

of the TC-5062C generates a consistent and predictable

TEM test

field

inside

the

cell.

The

radiation

field

from

a

device

transmitting

in

the

Cell

can also be

detected through the port using a test receiver .联华行 The unique compact and economical

design is optimized

for medium accuracy

measurements

beyond the standard TEM Cell frequency range.

TC-5062C 6 GHz TEM cell is made to work beyond the typical TEM Cell operating frequency range

limited by cell resonance. A typical TEM Cell is a 2-port symmetrical device; RF voltage is applied to

one port while the other port is terminated in 50 ohm while maintaining 50 ohm characteristic

impedance along the cell. Due to expansion and contraction parts of the cell, the wave propagation

beyond certain frequency is no more propagated by TEM mode alone and creates resonance. To

eliminate the resonance problem, the half of the cell is replaced by the wave absorbing material.

One commercial implementation is G-TEM cell. The size of the G-TEM design is too large for

typical small device applications due to the type of absorber used . TESCOM borrowed the concept of G-TEM, but changed the termination implementation scheme, and designed a very compact broad band TEM Cell that can be used on a desktop.

The operation principle of TC-5062C is essentially the same as TEM Cell. The E-H field inside the test volume is proportional to the input voltage and inversely proportional to the cell height. If a

radiating object is inserted inside the cell, the radiated wave toward input port is guided by the

transmission line and picked up at the input with a receiver such as a spectrum analyzer. With

this method, the RFI from a radiating Device can be measured quantitatively. Since this apparatus

is

very

broadband,

it

has many applications

in

the

area

of

EMI,

EMS,

receiver sensitivity

test, etc
