The HP-437B is a low-cost, high performance, single-channel, programmable, average Power Meter compatible with the HP 8480 family of thermocouple and diode power sensors. Depending on which Power Sensor is used, the HP 437B can measure from -70dBm to +44dBm at frequencies from 100 KHz to 50GHz.

Designed for ATE systems and demanding bench top measurements, the HP437B Power Meter makes fast, accurate and reliable average power measurements. Only 3 1/2 inches high and half rack wide, the HP437B minimizes the use of critical rack space in ATE systems. The advanced plastics technology used in the HP437B cabinet combines the light weight of plastic with the shielding effectiveness of metal, making the HP 437B the only power meter to meet MIL-STD-461C EMI specifications.

With a measurement speed twice as fast as that of the industry-standard HP 436A, powerful programming capability, state-of-the-art accuracy and exceptional reliability, the HP 437B lets you measure your test signal with speed, precision and confidence.
