Someone should take the nanoVNA/tinySA style platform and make a decent little curve tracer out of it.

My guess is, that won't happen very soon. 

- It is hard to make a good curve tracer to fit in a nanoVNA case (by good, I am thinking measuring ranges like 100V+ and 1A+).
- Yet, it is easy to improvise a curve tracer out of an AC transformer and an oscilloscope, or an AWG+DSO.
- Also, some testers/learning platforms can do low voltage and low current curve tracing.  Thinking of Peak DCA75 universal tester, which is pocket size and battery powered but doesn't have a very wide ranges of voltage/current.  Or Digilent's AnalogDiscovery, or the Analog Devices' ADALM1000 learning platforms.
- Then, the need of a curve tracer doesn't appear very often (at least for my typical use cases of debugging/tinkering with electronics).
- Last, there is already an affordable Chinese curve tracer (standalone, with decent enough measuring ranges).  It is smaller in size than the classic Tektronix curve traces, though it is not pocket size small, like a nanoVNA.

The CTL503 is a nice small tracer with medium volt, medium power capabilites, I'm liking mine.  Software is under active development and is good too.
