Linear sweep program
The program listing below performs a linear sweep as covered in Section 9. This program
sets up the following operating modes:
• Source and measure channel: channel 2
• Source mode: sweep
• Current range: 20mA
• Start voltage: 1V
• Stop voltage: 10V
• Step voltage: 1V
• Source delay: 100ms
