Measuring Instruments

Field Strength Meter (Transistor) Circuit: The Field Strength Meter is used to measure the radiation intensity from a transmitting antenna at a given location. With its own small antenna, it is essentially a simple receiver with an indicator. The wavemeter circuit with a rectifier-meter indicator, as shown in Fig. 10.2(a), is often equipped with a […]

Output Power Meter Working Principle: The Output Power Meter Working Principle is designed to directly measure the output power in an arbitrary load. The instrument provides a set of resistive loads to be selected for power measurements. In addition to power, the output power meter working principle can be used to measure impedance and frequency
