Teardown of a Tektronix 2465

Today at a time when digital storage oscilloscopes (DSO) are almost ubiquitous, analog scopes like Tektronix 2465 remain popular among many electronics hobbyists, especially among amateur radio operators who routinely work with high frequency circuits. I got my 2465 from ValueTronics. For those who haven’t heard about them, I would recommend you check them out as they have a large selection of used test equipment at reasonable prices.

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’ »
