Rigol DS1074Z Oscillosope

[alank2]

I like the double packing, gives more protection and provides a nice inner box to keep for storage.

[godFather89]

I agree. I saw once the way the packages are thrown all over by the guys paid to handle them...

Hi,

I never got this thing of double packing...

Maybe somebody at Rigol is an ex-postman.

If you look at the first pic there's a wrinkle in the cardboard at top-right. Looks like it was dropped on that corner.


PS: I just powered it on. So far, so good...

I got my DS2072A and DP832 with this double packing.

Cheers.

DS1054Z arrived here too! Upgrades like a charm

Rise time pics before and after upgrade of DS1054Z

250mV does not really count

Generate at least 2.5Vpp signal.

Good luck with your comments

What do you mean?

It looks like everyone who hacked ds1054z to "ds1104z" don't have a 100MHz+ generator to test it untortunetly.

I will get mine probably tomorrow.
Since I don't have high speed signal generator I will try to measure rising edge on Arduino Due (84Mhz) and Rasspberry Pi: http://goo.gl/YF9MdW

But I don't have 50 Ohm feed through terminator so I'm not sure if my measurements will be valid.

If you have access to an analog VGA output, the sync and video signals are a pretty good source for clean and fast rise and fall time signals.

[frenky]

Tnx. I'll see what I can find. (I do have some old laptops)

The scope was delivered today but I'll get to play with it after I get home from work.
I also plan to make one of these 50ohm terminators: http://goo.gl/ICvuHB

For those interested in one of the DS1054Zs here in the EU, I strongly suggest you PM (or email) EEVblog member Drieg (Petr Smid) to see if/when he might have them in stock (I don't see them listed on his site yet), because he will meet (and sometimes beat) Batronix deals - plus he's the nicest, most attentive dealer I've ever dealt with. He always sends me the latest FW updates as soon as he receives it. I would never buy a Rigol product (or anything he carries) in Europe without checking in with him first.

i think you checked wrong category (2 channel)...see under 4 channel, he seems to have them (

Code: [Select]

Brand: Rigol
Product Code: DS1054Z
Availability: In Stock ), and on top (of nice price) delivery in eu is free.
i better contact him to check.

If you have access to an analog VGA output, the sync and video signals are a pretty good source for clean and fast rise and fall time signals.

I connected it to the sync signal of a VGA output and saw approx. 4.7 ns Risetime. I don't have much electronic experience, so I don't know if it really handles 100Mhz.
On the colour signals I was not getting clean signals. Resolution of the signal was 1440x900 which should give 106Mhz.

[alank2]

I've been using a tactile switch just for fun to see how quickly it can drop and it seems to work reasonably well.  One side of the switch is grounded and the other is run to a resistor to vcc.  I then use the scope probe with the ground spring on the side of the switch connected to vcc.  Set the scope to measure fall time, trigger on falling, set the threshold to the center, and press the button.  On my ds2072 I get around 1.2nS or so.  It seemed like last year when I was doing this I had it even lower than this though.

Bandwidth depends on transition time and not resolution.  The last time I used a VGA output like this, even the sync signal edge times were faster than 300 MHz (*) so your 4.7 nanosecond rise time implies a bandwidth of 75 MHz (0.35 / 4.7e-9).  I am not sure how much faster than 300 MHz they are because that is the bandwidth of the fastest oscilloscope I have tried this with which did indeed report about 1.15 nanoseconds.

The color signals are more difficult to use but green should have the sync signals embedded in it.  If your oscilloscope supports TV triggering, then it should be able to use the green signal just like a composite video signal.  All of my Tektronix oscilloscopes which support TV triggering have worked correctly with the green VGA signal as the trigger source which I thought was pretty amazing given that they were intended for NTSC and PAL.  My ancient Tektronix 2440 DSO with the TV trigger option had no problems counting as many high definition scan lines as I could generate which was 1200 and more.

(*) VGA pixel clocks at high resolution require bandwidths of 300 MHz and higher but the performance implied by that bandwidth applies at any resolution.  In the past, VGA card bandwidth was part of the specifications because even at lower resolutions, it has an impact on display clarity.

It would be interesting to know how the Rigol responds to that, since it's spec sheet claims it maxes out at 576p.  The DS2000 specs higher, but that could simply be a matter of product differentiation.  Or, as you've mentioned before, Rigol could have imposed an artificial line-count limitation.

Is that with a hacked or unhacked DS1054Z?

[Fungus]

I just output an 8MHz square wave on a pin of my Arduino Uno and the rise time displayed on screen wobbles between 4.000 and 5.000ns.

(hacked 'scope, one active channel)

Edit: And very little ringing, I'm impressed....

I tried it with a switch and got around 2 ns (1.9 was the best).

It is hacked with the 100 Mhz option.

It worked now, but the Risetime was lower on the color channles than on the sync signal (10-15ns / 4.7).

I wonder if it is _any_ different unhacked.  I've got one coming Tuesday.  I'll test it before and after.

The ancient Tektronix type 109 pulse generator uses this technique with a mercury wetted reed relay to generate 250 picosecond rise time pulses up to 300 volts.

ciao, yes RIGOL has pretty often the double package and it is really good for us since we are more confident to ship instruments to users.
there are some items very difficult to predict as the DS1052E, it comes very often with single pkg, in this case we add one more bo with some soft protection insede, trying not to make the new pkg too big.

I agree. I saw once the way the packages are thrown all over by the guys paid to handle them... 

[Warhawk]

Guys do you have any idea if there is a chance to get rid of the YT screen when I enable XY ? I mean I would like to have XY mode all over the screen.
If not, is there a SW which can show XY mode in better resolution ?

[iRad]

Just got my DS1054Z in a double box. It is now unboxed, and a DS1104Z with all options...

I've asked the same question to the Rigol official support and they told me it is not possible.
