FNIRSI 2C23T (3-in-1) 2-kanaals oscilloscoop (10 MHz) + multimeter + signaalgenerator

Excellent instrument for the price. Sure it is possible to use the signalgenerator and oscilloscope simultaneously. You can switch between the two to change settings and see the results from the generator on the scope (by probe or a bnc cable). An instrument with many convenient functions, for instance the highly automated multimeter. Richly equipped with accessories, especially considering the price.

I have this instrument now two weeks. It arrived with only one oscilloscope probe, so that makes it less usable. I had contact with Elektor and they had more complaints about this. Still waiting for a solution.
In the meantime I tested the functions, they look OK except the oscilloscope part. Channel 1 is working well, but Channel 2 seems to have a software problem. As soon as a timebase of lower than 100ms is used, the Vavg and Vpp seem to be reversed.
For example when 5VDC is introduced to the probe with settings 2V, x10DC and 50ms(or lower) and the probe on x10, the graphics are OK, but the Vavg shows 2.56V and the Vpp 5.38V
Channel 1 shows with the same settings Vavg 5.02 and Vpp 0.15V and that is correct. When applying a waveform, frequency indications are correct on both channels.
Have to test a little more for the rest of the functions.
The idea of this instrument is great, but the bugs need to be fixed.
