The PicoLog program is rather old now and was intended only for data loggers and our early scopes with little memory.
Most of it's functions can be carried out using our current PicoScope6 program. PicoLog is supplied on the CD only because some early scopes are still being sold which can use either program. The 3406B has never been supported in PicoLog.
The only scopes we currently sell that are still supported in PicoLog are:-
2104, 2105, 2204, 2205 & 3425.
The 3224 mentioned at the start of this thread is no longer sold but did work with PicoLog.
Please contact me again if you have any other questions.
