Dear Group, I can finally afford a new oscilloscope to supplement my trusty TEK 465M. My budget is around $3k. I like the newer Agilent scopes, which I have used when someone else was paying. I do mostly low frequency high-precision instruments (analog signals less than about 1 MHz). The pretty lower-end Agilent scopes are in reach, but I'm tempted to use one of these: ...

Gentlemen, I'm just trying a number of combinations of L and C to find the right values for resonance at around 1.35Mhz. The problem I'm having is that the resonance point is far from clear. It's as if the Q of the components is very low (even though they actually aren't). I'm trying to think of a way to make it more 'peaky' on the oscilloscope display to take the guess work out of ...

Hi, I have been using an GW Instek SFG-2110 and find that the TTL output has a fast rise time. It is about 2 ns and this could be useful for oscilloscope bandwidth measurements for instruments of less than 100 MHz. The TTL option seems to be missing on more expensive function generators. Any thoughts?

As far as I know, using an oscilloscope for drones, I have absolutely no use for the BL's logic analyzer. But it looks like the inclusion of a logic analyzer is a huge value. Another concern with the BE is that apparently it is discontinued. Looks ike most of the problems people have with those two oscilloscopes are caused by their inability to use a PC.

I got one of those. Today, I tried to set up two oscilloscope probes. (the frequency compensation capacitor) I noticed the following things in bitscope-dso: when adjusting the cap, the waveshape doesn't change, but the amplitude does. at 250kHz it's almost triangles regardless of capacitor setting. 50kHz looks acceptable. I am also not sure what sort of filter it has and how to turn i...
