Bird Electronic 4381 RF Power Analyst w/6 Elements and Coaxial Resistor
The ruggedly built, multifunction Model 4381 RF Power Analyst features a digital display, microprocessor-based operation, and simplified, push-button control. This wattmeter is well suited to telemetry, two-way communications, avionics and radar, as well as standard radio and television applications.
- Power: 100 mW to 10 kW with 20% over-range. Reads forward and reflected CW or FM power in watts or dBm, Peak Envelope Power or SSB/DSB and symmetrical AM in watts, and peak power for pulses as narrow as 0.8us Calculates SWR, return loss in dB and % modulation Stores peak and multi readings to facilitate adjustment of maximum and minimum signal levels Shock-resistant keyboard and range switches. RFI protection
