POWER + SWR Meter

1,8 to 54 MHz (Version 1)

135 kHz to 10 MHz (Version 4)

The POWER + SWR Meter comes completely constructed and ready to use. A precision directional coupler is built-in for outputs over 1 kW. For power measurements, logarithmic amplifiers are used with a large dynamic range for forward and reflected Power. The SWR and/or the return Power are already “properly” measured with 100 mW Power. During the power measurement, the display can be switched between “dBm“ and “Watts“. A “PEP” function allows the maximum power to be displayed during the exchange and also during telegraphy. The PEP response time can be adjusted over an existing computer interface. The tuning process of PA’s is substantially simplified by switching on an incorporated bar display that will automatically indicate a decade (ex. 10 W ... 100 W or 40 dBm ... 50 dBm).
