Photodiode measurement program
The program listing below performs photodiode measurements as covered in Section 4.
This program sets up the following operating modes:
• Channel 1 measurement: current measurement, auto range
• Channel 2 measurement: optical power, R = 1, D = 0.
• Channel 2 MX + B units: M = 8.33333, B = 0.
• Channel 1 source: 10V range, +10V amplitude
• Channel 2 source: 100V, +20V amplitude
