Bird 4391A RF Power Analyst
The ruggedly built, multifunction Bird 4391A RF POWER ANALYST features a digital display, microprocessor-based operation, and simplified, push-button control. This wattmeter is well suited to C3, telemetry, two-way communications, avionics and radar, as well as standard radio and television applications.
Features
- Frequency: 0.45 to 2700 MHz. 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 of SSB/DSB and symmetrical AM in watts, and peak power for pulses as narrow as 0.8 μs
- Calculates SWR, return loss in dB and % modulation
- Stores peak and null readings to facilitate adjustment of maximum and minimum signal levels
- Shock-resistant keyboard and range switches. RFI protection
- Built-in international power supply/charger
