Swr Meter

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
