Anritsu ML93A Optical Power Meter

The Anritsu ML93A is an optical power meter designed for accurate measurement of optical power across a broad spectrum of applications. It is engineered to work in conjunction with Anritsu’s MA95A, MA96A, MA97A, and MA98A optical power sensors. The device is characterized by its user-friendly interface, featuring a digital display with a four-digit resolution, and an analog meter for at-a-glance readings. The ML93A offers versatile measurement capabilities, allowing selection between Watts, dBm, and dB (Relative) displays. It supports automatic zero adjustment and can be calibrated by inputting sensor-specific calibration constants for compensated readings. For enhanced functionality, an optional GP-IB interface is available. The unit can operate on AC power (100 to 130 Vac or 200 to 260 Vac) or an external battery pack (MZ95A), providing flexibility for both lab and field use.
