Both coax and waveguide one
and two-port setups are available along with supporting software,
accessories and components. These lines are provided with a test
sample that fits the sample holder and which is measured at DI prior
to shipment using DI's "MU-EPSLN" instrument control and data
processing software. The setups are usually packaged in a durable carrying case in which they may be stored
when not in use.
DI circular coaxial lines are available in standard diameters of
7mm, 14mm, 1.0", 1.5" and 3.0". For the most part,
the operating band extends from "dc" to a maximum recommended
frequency. Loss of TEM mode may occur earlier than the recommended
frequency, depending largely upon the index of refraction of the
material under test. Applications of DI coaxial lines, include liquid
cells, powder cells, ferrite testers. Solid materials may be measured
in clamshell holders which facilitate loading and can enhance contact
to well-machined samples.
The standard sizes of DI square
coaxial lines are 3.0", 6.0", 10" and 40". The
lines may be 50 or 60 ohm impedance. The 60 ohm impedance allows
complete images in the walls of the conductors to be formed, which
is of interest in the measurement of periodic structures. The lines
feature quick connections by means of latches and split sample holders.
These setups are commonly employed in the measurement of honeycomb,
loaded and lossy materials, and ferrite tiles.
Waveguide setups and components
for standard sizes from L to W-band are available. They may be furnished
with spit sample holders which allow solids to be loaded with good
conductor contact. In addition to solids, DI
setups are used to measure honeycomb materials and can be configured
as liquid cells. DI also offers Universal Waveguide Platforms, each
of which fits several standard bands, which allow calibration and
component connections to be made with minimum cable flexure.
Both High Temperature and
Room Temperature waveguide holders and universal platforms are available.
