This is the thing I mostly uses LAN for on my MSO6000. What would be handy though is the ability to do a colour-invert to get a white background for when you want to print it - annoying to have to put it throug a graphics program to do this every time.

Me too. Do you not have the 'invert graticule' checkbox?

Edit - only just noticed my 7104 doesn't have it!

Can you get a scope screenshot from the Agilent web interface?

yes!

You can also connect throught VNC to scope and take a screenshot. This feature I use rather that connection throught LXI.

There is a standard port 5900 VNC server running on the Agilent scopes?  All models?

Yes, it is available on 5900. I'm sure about all models, just try it or use some port scanner (e.g http://nmap.org/zenmap/ )
On 33522B which also is CE based, VNC is not available, but there is telnet on 5810.
On DMM 34411 based on WxWorks is also telnet available on same port.

Damn, sure wish Rigol had this, though i've not port scanned my DSA either..  I assume the DSA and the scopes would be the same if they had it.

Thanks

I have only one Rigol power supply DSP1308 and on this only the port 80 and 111 are open.

Doesn't Rigol claim LXI compliance for it?

A LXI instrument must provide the discovery procedure taken from VXI-11. And that requires an RPC port mapper listening on port 111. To discover instruments a control software is supposed to perform an RPC broadcast and then set up an VXI-11 connection to a responding instrument.  LXI only requires that an instrument understands one single SCPI command via that VXI-11 connection, the *IDN?  command, and responds with its ID info.

A LXI instrument is also required to provide an XML description file of its capabilities at the http://<instrument ip address>/lxi/identification url. That document should have a section listing its network interfaces.
I delete PMs unread. If you have something to say, say it in public.

There was a typo, opened ports are 80 and 111 of course ;-)

Has anyone bought the App Bundle for the 2000 or 3000 scopes? For the 3000 series its called DSOX3APPBNDL and included all software upgrades and in the UK its  £538.00. I'm tempted for the serial decoding features and I'd be interested to see how well the power measurements application works but I'm not sure I entirely trust it..
Thanks,
Nick

Just bought the App bundle for the DSO-X 2024A. It's called DSOX2APPBNDL

Was not sure what to expect but received a large padded bag (45x31cm) Inside that was another padded bag (35x24cm)
Inside that was an A4 sheet of paper which was the License Entitlement Certificate.

It would have been so much easier and cheaper to email it as a PDF

At least I wasn't charged postage.

I have the 3000X app bundle.

Serial decoding works brilliantly well, though it does have a limitation whereby it seems only able to decode serial data as it is captured, and doesn't work on stored data. So, you have to set up decoding correctly first, then capture data with the decoder enabled. You can't capture a data stream once and then play around reconfiguring the decoder options until it decodes correctly. Apart from that, which is a relatively minor inconvenience IMHO, it's great. (Note, bizarrely, the 2000X series can't do serial decoding on the digital channels - only the 3000X can do it).

The power measurement features look very comprehensive if you're in the business of designing circuits powered directly from the mains, but I don't have a current probe or isolated differential probe to use with them. Without this extra hardware, I don't think there's a great deal of benefit.

Which pisses me off greatly. They don't really mention it explicitly. They just say "MSO2000 Series oscilloscope with serial decoding" and one the same spot in the 3000 series data sheet ther's an extra "on all digital channels". So you have to compare both datasheets to figure that one out. Did someone find a hack to enable serial decoding on the X2000 series digital channels?

The lack of a hardware frequency counter seems to coincide with the lack of equivalent time sampling. The frequency counter works by looking at the output of the trigger comparator, not the ADC result. The problem with not having equivalent time sampling is trigger jitter. If you measure a fast risetime signal (a risetime of perhaps a few sample periods), it will appear to jump around somewhat, +/- 1/2 the sample period. This is because the scope can only trigger on the sampling clock, whereas in real life the time the signal crosses the trigger threshold can be between sample clocks. Equivalent time sampling basically tells the scope what phase the sample clock is relative to the trigger, with extremely high accuracy, in the tens of picoseconds range. The display system must then shift all the sampled points by this amount. This removes the +/- 1/2 sample period jitter. If you're making high speed jitter measurements this is critical. The Tek 4000 series scopes lack equivalent time sampling too, but those those are high end, the base model is $10k!!

The actual trigger to clock delay may still be calculated for use with equivalent time sampling in a way similar to how a transition midpoint timing time to digital converter works:

http://www.ko4bb.com/~bruce/TDC.html

An odd side effect of doing this however is that the triggering will be susceptible to aliasing on fast edges which will cause excessive trigger jitter.  Aliasing even on benign input signals will occur because of jitter and non-linearity in the digitizer itself.  Maybe they use some DSP magic during decimation to alleviate that but I would be interested in seeing oscilloscope evaluations which tested for it.

I have noticed that all low end DSOs and most (all?) mid range ones no longer support equivalent time sampling even when their real time sampling rates are insufficient for their fastest horizontal scales but that takes some of the bite out of only having old DSOs available.

As a current probe you can use some LEM transducer e.g CKSR series, they are cheap (20EUR) and BW is about 200kHz.

Thanks! So the license appear all separated and not as a single 'bundle' or 'all' license.

Not as severe as with yours, but it jumps a bit. Same scope as you with 2.37 firmware. I fail to see what the big deal is.

About 70ns but not consistent.

On a DSOX3034A (2.37) I get about -48ns of shift at 200ns/div. 

Could someone compare with a signal with much larger slew-rate?
The slew-rate of my test signal is about 2.5V/1.25us

But i do not buy Keysight devices again.... :(
Unfortunately, there is no competitive scope in this cathegory and price from LeCroy, Hameg or Tektronix. Maybe you would be happy with Siglent or Rigol?? But I do not think so.

Well, this is a rather minor bug. At least Keysight scopes hardly ever lock up. (Never happened to me since I bought my scope in 4/2013.)
EDITED.

Maybe I'm missing something, but I'd also say it's a rather minor thing. Okay, if the bug shifts the signal relative to another signal, that might be a big deal. But if all signals are shifted (which would be logical, since it's a trigger), you can simply adjust your horizontal offset.

Edit: Just confirmed that all signals are shifted, not just the one you triggered from. So not a big deal.
