My measurement devices

              

1. Scopes and generators

I like old devices and for a long time I worked with them and I also constructed some of them (ocilloscopes, frequency counters, signal generators. But as the time was gone, I couldn't withstand and I bought some of the newer ones. The first two are of that sort and I have a big enjoyment to work with them. Another benefit is more place on the desk.

To achieve the maximal enabled precision with a measurement device a calibration is needed using an accurate and calibrated device or another exact resource. If we have a four digit device or a 0.05% device we don't have automatically also a 4 digit or a 0.05% precision. So it can happen, that although we read 4 digits, one or two least significant digits are "house numbers". But for most practical measurements it would be enough.
