Anritsu ML2437A Power Meter

The Anritsu ML2437A is a single-channel RF and microwave power meter engineered for accurate measurement across 100 kHz to 65 GHz (sensor dependent). It combines thermal meter accuracy, diode meter speed, and peak meter visualization in one instrument, making it ideal for diverse power measurement tasks. The meter samples at over 35,000 samples per second—extendable to 100 kHz for high-resolution profiles—capturing detailed power signatures of pulsed signals found in cellular, PCS, TDMA, GSM, and radar systems. A standard graphics display renders time-domain representations and burst profiles of pulsed waveforms with 0.1 msec resolution. Pulse-top power measurement is repeatable using cursor averaging across single or multiple pulses. The ruggedized, splash-resistant housing supports field service deployment, while an optional high-capacity NiMH battery extends runtime.
