USER‘S MANUAL PART 90099905. REV B-6/28/23 3 Operation 3.1 Introduction The Newport Models 1801 and 1811 125-MHz, low noise photoreceivers address the needs of the photodetector community in the area of low-noise, high-gain, RF photoreception. These photoreceivers are available either DC or AC coupled. Their typical bandwidth is 125 MHz with a current gain of 40 V/mA. -
Page 8: Handling Precautions
USER‘S MANUAL PART 90099905. REV B-6/28/23 3.2 Handling Precautions Whenever handling the photo receiver, make sure to follow these precautions: Prior to handling the unit or making connections, be sure to ground yourself adequately-even • small electrostatic discharges could permanently damage the device. A ground strap provides the most effective grounding and minimizes the likelihood of electrostatic damage. -
