The General Radio 1602-B UHF Admittance Meter was introduced in 1954 Catalog M and remained available through Catalog78 1978.
The Type 1602-B is a null type instrument designed to measure admittance at UHF frequencies with coaxial systems. It performs this by the use of three loops parallel connected to the detector. The three loops are coupled magnetically to the unknown admittance, conductance standard and susceptance standard lines which are driven directly by the generator. By adjusting these loops for a minimum (null) at the detector a direct reading from the three scales in determined. The 1602-B is an update from the 1602-A with an expanded "Multiplying Scale" and locking coaxial connectors. Supplied with the instrument are two multiplier plates that improve accuracy, resolution and range. The susceptance scale is direct reading only with matched serial numbered susceptance standards supplied with the instrument.
Specifications
- RANGES OF MEASUREMENT
- Conductance: 0.01 to 4000 m℧.
- Susceptance: -4000 to +4000 m℧.
- Frequency: 40 to 1500 MHz, direct reading.
- Accuracy (conductance and susceptance): Up to 1000 MHz, from 0 to 20 m℧, + (3% ± 0.2 m℧) from 20 to 00 m℧, +(3 √M% + 0.2 m℧) where M is the scale-multiplying factor.
