The Keysight (Agilent) 437B is a single-channel, programmable average power meter designed for fast, accurate, and cost-efficient RF and microwave power measurements. Compatible with the 8480 series power sensors, it covers a wide dynamic range from -70 dBm (100 pW) to +44 dBm (25 W) over frequencies ranging from 100 kHz to 110 GHz. Its compact 3-inch height and half-rack width make it ideal for space-sensitive ATE systems and demanding bench-top applications.
The 437B integrates a power reference for automatic calibration and zeroing, features ten preloaded sensor correction factors versus frequency, and is the only meter in its class compliant with MIL-STD-461C EMI specifications. It combines the lightweight form of plastic with the EMI shielding of metal for robust system integration.
Testwall can supply the used Keysight (Agilent) 437B, fully tested. With expert support and global delivery, Testwall ensures high-performance instrumentation with unmatched reliability and service quality.
