R3-33 impedometer

Also, this device can be called: R333, R3 33, p3-33, p333, p3 33.

R3-33 meter measures the impedance and VSWR phase of the reflection coefficient RF coaxial input paths with a meter and decimeter wavelengths.

Measuring R3-33 are coaxial tee, one arm of which is loaded with a reference capacitor. To the other shoulder gauges connected load measured. By asymmetrical shoulder tee fed signal from the microwave generator. Above the center of the tee set round wordly waveguide on which input has a filter of parallel conducting plates. Reception is located above the filter freely rotating loop detector to isolate the low-frequency component.

Specifications R3-33:

VSWR measurement range - from 1,1 to 10.

Range measuring phase - from 0° to 360°.

Frequency Range - 20 MHz to 150 MHz.

Impedance - 75 Ohm (16/4,6 mm).

VSWR measurement error (at KstU ≤ 2) - no more than ±7%.

Phase measurement error (at KstU = 2) - no more than ±7°.

Dimensions - 292×135×190 mm.

Mass Meter R3-33 - 3,8 kg.

Measurement of VSWR and reflection coefficient phase R3-33 load meter made ​​by rotating the receiving head, which is a circular waveguide ultraboundary which is located above the center of the tee junction. In the branching occurs complex field of electromagnetic waves incident and reflected from the reference capacitor and the load measured.

The ratio of the maximum and minimum values ​​of the output voltage from the loop, is the square of the standing wave ratio. The angle between the loop under certain provisions of the output voltage at idle and load when measuring an unknown phase of the reflection coefficient is equal to the load, and turn 360° loop will always be equivalent to a distance equal to one wavelength regardless of the frequency of the signal.

Due to the lattice filter structure receiving the head of the field in the evanescent waveguide is greatly simplified. Located inside the waveguide loop connection, loaded onto a detector. When rotated 360° loop can obtain two maximum and minimum values ​​of two voltages.

Countdown VSWR gauges R3-33 is produced as and when you use the measuring line. The spatial angle corresponds to the hinge connection part of the phase of the reflection coefficient.
