Default Re: Best 100MHz analogue oscilloscope?

Don't underestimate the HP 1740A

It has a few things going for it.

1) Internal access is a whole world easier than the Tek 465/465B

2) No HP scope has ever triggered on any waveform ever, just check the internet! Remind the seller of this and you can haggle him down to pennies.

3) No fan noise... no fan... importantly no need for a fan. Runs cool.

4) Switched 50 Ohm terminations on both channels.

5) Everyone I've had comfortably exceeds bandwidth spec.

6) ECL trigger logic, no tunnel diodes.
