General Radio 1602-B 1602B UHF Admittance Meter
Used to measure FM and TV antennas and transmission lines. The 1602-B is for the measurement of admittance and impedance over a wide frequency range. As a null instrument it can be used to measure the conductance and susceptance of an unknown circuit directly. It can also be used as a comparator to indicate equality of one admittance to another or degree of departure of one from the other. As a direct indicating device it can be used to determine the magnitude of the reflection coefficient on a 50 ohm coaxial line or the magnitude of an unknown impedance for ratios of output voltages read on a meter. It uses three coaxial lines at right angles, one terminated by the unknown admittance and the other two terminated by a pure resistance and a pure rectance. Sampling loops in the three lines are connected in parallel, and when the loops are adjusted to produce a null the parameters of the unknown are displayed. It is direct reading from 40 MHz to 1.5 GHz, and can be extended to 20 MHz with a correction. The two multipliers (faceplates) provide admittance measurements from 0.01 mmho to 10,000 mmho and susceptance measurements from -200 to +200 mmho. Basic accuracy is 3%.
Our unit is a BEAUTY and comes with:
Wood Case, 2 Multiplier Plates, 2 1602-P4 Gs 50 ohm Terminations & Manual.

North Atlantic 540 - S746 Resolver / Synchro Bridge Input to Null Output
This bridge allows for direct measurement of the angular shaft position of both 3 wire synchros and 4 wire resolvers. Its unique bridge circuit design provides a constant null voltage gradient over the entire angular range. When the input is connected to the standard line to line levels of 11.8, 26, 90, 115 Vrms, it provides a null output in either the Synchro or the Resolver mode.
The high input impedance coupled with the ability to measure synchros and resolvers either as components or transducers in operating systems, allows for usage in the lab, the line or ground checkout.
