Once you understand how a curve tracer, Huntron Tracker or scope octopus works then the signatures make sense and become easy to diagnose. Thanks to rugged, reliable equipment (photovoltaic modules), it allows you to produce electricity which you can then use for your own needs or sell on to a power distributor. Many hams enjoy experimenting with electronics and troubleshooting circuits. · Automated C-V and I-V curve tracers (The Keystone B1505A and the Keithley 4200-SCS) · Solar Simulator with curve tracer (The IV-5 Simulator) · QE and Spectral Response Measurement System (The QEX7 System) · more equipment to be added in the near future. I took a screen shot of. OVERVIEW: Your teaching assistant will also give a weekly quiz on the lab you are. Elektor did a USB-linked curve tracer in early 2009. When the resistors where discussed earlier I recommended that you should have only 2 resistors. I have one of those too, but they are very limited in what they can do. Since MOSFETs’ gates do not draw any current in steady states, the Vgs steps are fixed regardless of the value of R28 in this setup. It allows sweep measurements to be modified in real-time just like on a curve tracer, and both voltage and current can be. Happy testing!.
