NEW TOOLS
R-F MEASUREMENTS
AMCI Precision Hybrid
Type 1025
Frequency range: 100 me to 300 mc
PERMITS DETECTION OF
SWR's AS LOW AS 1.002
THE TYPE 1025 PRECISION HYBRID is a five -terminal, high- frequency
network built with particular attention to stability and accuracy of construction.
It makes possible the measurement of quantities that have
been, normally, only estimated. For example: this device can be used to
measure at about 200 mc. a reflection coefficient as low as 0.01. with a
precision of _0.001 in magnitude and ±5' in phase angle.
VERY LOW SWR's can be
measured by using the Type
1025 Hybrid with a suitable
receiver and signal generator.
With additional equipment,
the phase angle also
can be obtained, permitting
point -by -point plotting of
impedance curves like the
one shown at the right.
CHART FULL
DIRECT DISPLAY OF IMPEDANCE can be
obtained by using the Type 1025 Hybrid in
conjunction with the AMCI type 1028 Polar
Display Unit (frequency range 120 mc to
240 mc) together with a standard d -c oscilloscope
and suitable swept oscillator. A typical
display is shown in the unretouched photograph
at the left.
