Title: Board band electric field strength meter
Inventor: SUZUKI EIJI
IPC: G01R29/08
Filed: 1988-10-20
Abstract: PURPOSE:To perform measurement for a broad band by making a bias current flow to a detecting diode so as to improve rising characteristics, obtaining broad band characteristics, and adding a temperature compensation function using a thermistor. CONSTITUTION:A bias current always flows into a diode D1 from a DC power source E through a resistor R3, a resistor R2, a variable resistor VR1 and a diode D2. Under this state, a sensor part S1 is brought into contact with a material to be measured, and measurement is started. Then the received signal from the sensor part S1 is transmitted to the diode D1 through a coupling capacitor C1. Since the bias current flows in the diode D1, the rising characteristics of the signal are very excellent. The signal which is detected in the diode D1 is amplified in a transistor TR. A DC ammeter M displays the magnitude of the amplified signal. Temperature compensation is performed with a thermistor CT.
