The Marconi IFR Aeroflex 6914S is a thermocouple power sensor delivering precise RF power measurements across 10 MHz to 46 GHz. Built for field and bench deployment, it measures power from -30 dBm to +20 dBm with ±0.5% accuracy at 100 mW and 25 °C. The semiconductor thermocouple sensing element handles continuous RF input up to +25 dBm (300 mW) and peak signals to +42 dBm (15 W) for 2 ms bursts, making it suitable for communications, radar, and microwave equipment testing and maintenance.
