The Newport 1830-C Optical Power Meter is a ±20,000 count A/D resolution, autoranging picoammeter. Measurements are displayed on a large 4 1/2 digit liquid crystal display (LCD) and can also be taken remotely via the RS-232C port or the IEEE 488 GPIB bus. The 1830-C is designed to take continuous wave optical power measurements and is compatible with all of Newport’s Low-Power Semiconductor photodetectors. Specifications. Absolute Maximum Line Current Rating: 200 mA. Signal Ranges: Up to 8 decades (dependent on detector type). Display: 4.5 digit, annunciated, backlit, wide angle view LCD. Display Update Rate: 75 ms. Auto-Ranging Time: 200 ms (typical). GPIB Bus Transfer Time: 10 ms (typical). Analog Output Full-Scale Voltage: 2V into 1M-ohm, Full-Scale Accuracy: ±1%.
