Swr Meter

The model NV 103 SWR meter is a high gain low noise, tuned amplifier operating at fixed frequency. It is designed for making standing wave measurement in conjunction with a suitable detector and slotted line or wave guide section. It may be used as null detector in bridge circuit and as fixed frequency indicator. It is calibrated to indicate directly SWR or db when used with square law devices such as crystal diode. It has expanded scales for accurate reading of small increments. It is adjusted for operation at 980Hz to 1020 Hz to avoid harmonics of the line frequency. PC to PC communication facility in SWR Meter is available only with gunn based benches
