2-10 Getting Started Model 2520INT Quick Start Guide
Programming example
Table 2-5 summarizes the basic command sequence for optical power measurements using
MX+B with detector 1. These commands set up the Model 2520 as follows:
• Measurement range: 10mA
• Math function: MX+B enabled
• Responsivity: M: 2
• Dark current: B: 0.5
• Bias voltage: -5V
