High-sensitivity peak and average power measurements

Keysight diode power sensors offer exceptional precision and high sensitivity, ideal for low-level RF and microwave power measurements. Diode technology ensures precise detection of weak signals that other sensor types may miss. With optimized standing wave ratio (SWR) performance, these sensors minimize signal reflections and improve impedance matching, enhancing measurement accuracy. Their excellent temperature stability ensures consistent performance in varying environmental conditions, making them perfect for long-term testing.

High sensitivity

Provides high sensitivity, leveraging diode sensor technology to capture low-level signals that other sensor types may fail to detect.

SWR performance

Minimizes mismatch uncertainty with optimized standing wave ratio (SWR) performance, reducing signal reflections, and ensuring better impedance matching.

Temperature stability

Offers minimized drift across operating temperatures to maintain measurement accuracy for long-term monitoring and testing under varying conditions.

Fast measurement response

Delivers rapid settling times and high measurement speed for time-efficient power readings, enabling quick averaging and faster throughput.

Frequency range 50 MHz to 50 GHz, 10 MHz to 18 GHz
Power range -70 to -20 dBm
Connector type 2.4 mm (m), Type-N
Measurement type Average/CW only
Maximum power 20 dBm (10 uW)
