DSO-X 3034A Upgrade Questions

I have a DSO-X 3034A oscilloscope. It has a Digital interface, for a digital probe. I was considering buying a probe to have access to the digital channels. But it's not clear what is required vs. what is available.

There is an accessory: DSOX3MSO. It does come with a digital probe, it appears. But is this more than what I need. It also looks to be some sort of DSO to MSO upgrade.

1) Does this kit convert the DSO to an MSO instrument?
2) Does it do more than just provide a digital probe?
3) Is there such a thing as a digital probe that isn't the MSO

I'm just trying to understand what is required, to make use of the digital connector on the front of my scope. Digital input is what I'm after but an MSO upgrade would be ok too, if it turns the DOS into the same capability as an MSO.

There is another option: DSOX3EMBD. This appears to be an I2C and SPI analysis tool.

4) Does my DSO-X 3034A have any I2C capability, as it exists without this kit? I guess I could just test it, after I start using it but that's a few days away and I'm looking for upgrades now.

5) What capability does this kit add, that I don't have now?

I'm also going to be using this for some power testing. Mostly measuring current, voltages and power consumed. There are two other kits that seem to be related to power, but I'm not sure if these are strictly needed or just something to make things easier. DSOX3Mask and DSOX3PWR.
6) Are these just applications on the PC?

Thanks,

By definition (at least by Agilent's definition) and MSO is a DSO with digital channels. Adding the DSOX3MSO upgrade adds the digital probe, and adds the ability to trigger on many combinations of digital and analog phenomena, such as "Analog edge, while a specific digital value is onthe digital side".

There is another option: DSOX3EMBD. This appears to be an I2C and SPI analysis tool.

I suggest that you read the datasheet, if you haven't already. It talks about the triggering and display capability that is added by the I2C/SPI option. Link to DSOX series Datasheet

6) Are these just applications on the PC?
Again, look at the datasheet. There is a list of the capabilities and measurements added by each of these options. Both of these run on the scope.

I remember in another life using an Agilent (or was it an HP) 16500 logic analyzer. It had an option where you can add two analog channels and use it as a mixed signal logic analyzer. Now it's the other way around !

In that same life we used a T1 mask for testing T1 drivers. It was a very usefull tool for tracking bit errors caused by deficiencies in the matching network or transmission lines. DSOX3Mask is a way to set up boundries on the oscilloscope screen to test "eye" patterns, sine or square waves. If the signal exceeds the boundries, the scope will capture the event. Here's a Pass/Fail Mask Testing Demo Video

You could do that with the 16700 also. The ongoing problem was that the specs on the scope cards were always worse than what was available with a standalone scope. If a new scope architecture came out, it had to be adapted to a new form factor (LA plug-in card) and a different SW architecture (LA), before it could be plugged into the LA, so it always lagged behind.

With the newer analyzers (169xx and U4xxx), you can cross-trigger almost any Agilent scope with the LA. The trigger can go either direction, through a BNC cable. The data gets transferred from the scope to the LA and scaled both in time and voltage, via LAN. Trigger delays are removed, so that they are correctly correlated. The scope marker locations are transferred and displayed in both places. They can be adjusted from either place. Voltage values can be displayed on the LA. The screen updates can be fast, as fast as 1-2 per second. The tightly integrated triggering of an MSO is not available, but State analysis is available. You can capture the input and output of an A/D or D/A, and graphically compare the data.
