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%.
