I'm awaiting delivery on an MSOX2024A and while reviewing specs and features was unable to find several things that I'd like to know.
1) does this series have vertical offset control? The remote commands have a "channel offset" which appears to be exactly that (or is it simply vertical position?). I see no mention in the user guide of a vertical offset control to "inject" a +/- DC offset to the selected channel.
*If there is no softkey equivalent, please, please get the firmware people (and of course marketing) to add it.*
2) what is the timing resolution of the logic channels? I see 5ns minimum pulse but am hoping it's better than that (or perhaps there is a glitch / runt mode for the LA ?)
3) bummer that this scope does not have a 50 ohm input selection ... a 50 ohm termination in line with the scope input impedance no longer looks like 50 ohms. I know, it's good enough for most uses but I believe the combination does have some peaking as you approach 200MHz.
Still, the new Agilent scopes blow away the offerings of my previous favorite (for over 30 years) scope company.
Thanks,
Den

On most of the older Teks I've used, the vertical menu has a separate control for offset to remove dc offset from the channel input. This is very handy for observing noise or other modulation riding on a dc component. The offset can also be entered by keyboard which is very handy if you want to remove, for instance, a known dc reference level.
It appears that the Infiniivision scopes, the vertical position control also acts as the offset control and the offset voltage is shown momentarily as the knob is turned.
The specifications also indicate that you do have control as you have a +/- 2V offset (for example) on any range less than 200mV. And you also have coarse / fine control (I believe) when you press the vertical pos button.
It sounds good so we'll see how it works out !
