Description
Description
PEP-Dual Element, RF Power Analyst
The 4391A, RF Wattmeter monitors Peak Pulse Power, Peak Envelope Power, or CW Power during normal equipment operations in the forward or reflected direction. Designed for air navigational aids DME, ATC and other pulsed RF systems such as telemetry, radar, command and control, etc. They need no attenuators, directional couplers or charts.
Features
- Frequency: 450 kHz to 1.2 GHz. Power: 100 Mw – 10 kW
- Reads forward and reflected CW or FM power in watts or dBm, Peak Envelope Power of SSB/DSB and symmetrical AM in watts
- Calculates SWR, return loss in dB and 5 modulation
- Shock-resistant keyboard and range switches. RFI protection. Built-in international power supply/charger
