Keysight-Agilent 438A

The 438A Power Meter is a dual-channel power meter designed specifically for ATE systems. The compact front panel saves critical rack space, while the dual channel design allows simple and accurate measurements of the ratio and difference of power levels from two separate sensors. This meter is compatible with the 8480 series of thermocouple and diode power sensors. HP-IB capability is standard.
