ML2438A Power Meter
The Anritsu ML2437A Power Meter combines the advantages of thermal meter accuracy, diode meter speed, and peak power meter display graphics. The result is a single instrument that samples at more than 35K per second and achieves 90 dB dynamic range with a single sensor. This meter includes graphics display capability as a standard feature. The ruggedized housing and optional high-capacity NiMH battery bring laboratory quality accuracy to field service applications. Anritsu ML2438A has two inputs.
