Early models displayed vacuum tube curves; later ones were of course aimed at measuring transistors, diodes, and other solid-state devices. Plug-ins for Tek 5000- & 7000-series scopes ... most easily ...

Oh, and finally, note that some Zener/Avalanche diodes will exhibit negative resistance, at some narrow portion of their operating curve (One researcher has indicated that between 75 and 80 ...

The diode voltage vs. temperature curve can be measured using the EVQ4572-QB-00A evaluation board (Figure 2). It can also be measured directly from a custom board. Here, it’s important to note that ...

I use simpler method. Connect laser diode to 5 V supply and 470 Ohm resistor. No lasing – go lower with resistance, to 390 Ohms. No lasing, go lower to 330 Ohms, etc … until lasing starts.

Series troubleshooting: Bypass diodes fail regularly, ... Measurements of I-V curves or similar tests on each string or module are too costly at this stage.

The first curve tracer, the 570, was introduced to display characteristic curves for vacuum tubes, followed over the years by models for testing transistors, diodes and other solid-state devices.
