Oscilloscope Probe Rise Time Testing

In this blog post, I compared the rise time of four oscilloscope probes of various bandwidths using an avalanche pulse generator and a Tektronix 2465 300 MHz oscilloscope. The bandwidth of an oscilloscope probe is typically characterized using a network analyzer. But using a sub-nanosecond rise time pulse generator and a reasonably high bandwidth scope, we can infer the approximate bandwidth of the probe under test using the following equation: Continue reading ‘Oscilloscope Probe Rise Time Testing’ »

My New DS1052E Oscilloscope

I used to own an all-transistor, single channel 10 MHz analog oscilloscope. While it was not adequate by nowadays standard, it served me quite well for many years. The scope was later sold and I had been thinking about getting a new oscilloscope for quite a while. This time around though, I wanted to get a digital storage oscilloscope (DSO) since in many cases, it is a lot more convenient to use. After reading about some rave reviews on Dave Jone’s EEVBlog about this Rigol DS1052E scope, it became apparent that this would be the ideal scope for my workshop. So without much hesitation, I ordered one. Continue reading ‘My New DS1052E Oscilloscope’ »
