" analog scope with 400 MHz bw that will do FFT"
how schould an analog scope do FFT?

Well.... if you can find a 4-channel secondhand analog scope with 400 MHz bw that will do FFT, Frequency counting, pulse width and screendumps for 400 dollars, and comes with 4 probes... buy it, by all means!
I actually was about to do (old 1Ghz Lecroy for 300usd) but got distracted by Daves used-care-salesman approach in the end of the 1054z video!
Otherwise, get a Rigol 1054z, unlock it to 100 MHz and just don't use the features you don't want. Do you really need 400 MHz bandwidth, on your budget?
The hack is great dont get me wrong on this but that is not part of my scope request, 500Mhz is also fine as well as 1Ghz etc.
For instance i could tomorrow order a Rigol DS6102 for 7620 usd from my local supplier, but why on earth would i spend such a fortune just to look at high speed signals?
Is there a scope like box where i can attach a old PC screen to display the measured 477Mhz wave? Basically i dont need an oscope in traditional sense if you get my hint!
I need a Ghetto style high speed wave display!
Is there some kind of scope that acts differently? Don't we all do just exactly this when we are looking at a waveform for the first time?
All analog scopes and the early digital scopes I remember used the left side of the screen as the trigger origin, unless you've explicitly set a delay. To be honest, I don't have a lot of experience with modern DSOs. I suppose my way of thinking is still rooted in the old analog storage paradigm, where you wouldn't want to throw away half of the screen.
I was about to buy a 1054z but sadly to say i had a second thought because i come across the 1054 bug and wish list and the fact the input bandwith is dived among the channels
Either you are using the wrong terminology or you're getting mixed up with the difference between sample rate and bandwidth. All 4 channels always have 100mhz of bandwidth (or 70, or 50 depending on model). It is the
sample rate that gets divided and that happens only if you have the extra channels enabled.

A Tek 7000 series mainframe with a 7L12 Spectrum Analyser plugin could do better than an FFT.
Of course,you couldn't send it to a PC,or save it,other than with a digital camera.
You could probably get a 7000 series mainframe which could do the 400MHz as a normal 'scope,too!

My point exactly, since the OP said,
What i need is scope that do example 400Mhz, FFT, freq counting,PW and and who can do screen dumps in a suitable bitmap format for similarly amount of money and that's about it. I dont have the time or patience to read all the million posts about different scopes but with my requirements i'm i stuck with old secondhand analogs market or is there something new like this around?

Yes, that's what I thought he meant. Thanks for correcting.

Well, if that is really your requirement I have to wonder why you posted in the "Re: New Rigol DS1045z oscilloscope" thread ! Are you doing the "wind-up" by chance?
Get that old LeCroy for 300 dollars, then! And of course you will need at least one probe with 500 MHz bandwidth, if you care about precision in the displayed waveform! Good luck with that!
Hello,
I have measured the frequency response. You can clearly see the differences.
The Tektronix oscilloscopes have a steeper drop. The Rigol DS1054Z is much flatter, also in the 100MHz option.

If your waveform is repetitive, you should consider scopes from the late 80s and early 90s. They had relatively low real time sampling, but with random sampling an equivalent sampling of several GS/s. Also the analog inputs were quite powerful back then and had smooth frequency response instead of the brickwall-like in more modern ones.
The Lecroy you mentioned is such a device. The HP-Units from that time-period should be able to do the job as well. These scopes also most likely have RS232 installed as standard, so you can extract the data via the serial-port and perform FFT-Calculations in excel or Matlab or whatever program you're using, like it is described here:
https://www.eevblog.com/forum/repair/repairing-an-old-pm3320a/75/If you have the equipment available to characterize the frequency-response of the analog inputs, I think you can also use lower spec units like the PM3394 or even the PM3384 and reconstruct the real nature of the signal afterwards in Software. PM3394 Scopes also have the advantage to switch into analog-mode.

Thanks for any info and your time regarding this!
This is a thread about the DSS1054Z. You don't have time nor patience to read and understand all the information other have taken the time to provide? So now you want everyone to change the discussion, and talk about things that aren't a DS1054Z and jump to your commands to give you help on your terms?
Why not start another thread about what YOU want to talk about. Why be like most people on the internet and pollute threads with off topic posts?

Does anyone know what is latest firmware update and can I get it without registering
My plan was to update to the latest software and upgrade to DS1104Z.. Have you guys had any problems with the updates and the upgrade hack or any other kind of issues
My specs
Spec- DS1054Z
Software-00.04.03
Board-0.1.1
Thanks
Thanks for the info ..
I am sorry I had to ask but the manual said to use Rigol.com but the website doesn't have the DS1054Z listed but if I used the
http://www.rigolna.com webiste then it has all the information but I was sure how valid the website was since the manual said to use the Rigol.com site ..Also I am starting to learn Electronics and I was if it was in best interest to do the upgrade or am I better off sticking with stock setting
? How much do you lose after the trial upgrade is done ??
www.rigolna.com is the official Rigol North America site. Not the main China site.
As far as upgrades... The bandwidth and memory depth are the most important for me. The extra triggers and decoders I've used to a lesser degree. If you're going to upgrade, do them all and be done with it. Use
DSER. Do NOT enable the 500uV/div option as it doesn't work properly.

Is it DSER or DSFR cause there is not listing for the DSER and everyone keeps saying it but no listing using the link below.
http://gotroot.ca/rigol/riglol/
Everyone keeps saying DESR because that is what you should use. USE DSER NOT DSFR!!!!!
Version 00.04.03.SP1 is the latest. Disregard the zip filename and see the directory name inside.
And Firmware Release Notes.
Does pt.7 in the Release Notes mean that Rigol has repaired the zoom freeze bug ?
pt.7:
In scanning mode,turned on the Zoom display and setted the AC as the trigger coupling,then adjusted the timebase of Zoom zone and the waveform display error.

It's DSER. The list of codes hasn't been updated in quite some time. You do not want to enable all options because 500uV is not supported on 1054z. So type in DSER and you'll be all set.

E: Everything that works
F: F***s the scope

That's right. But what is confusing some people is probably that the DSER code is _undocumented_ in the Riglol keygen. It's not listed as an option... but it works anyway.

Unfortunately... no. The scopes that have the bug will still freeze when Mem Depth is 'Auto', Persistence set to 100ms or greater, and Horizontal Zoom (aka Delayed) mode is entered. Or at least mine still does, anyway, running 00.04.03.SP1.
A Rigol tech told me that there is supposed to be a new firmware version coming in October. Will it fix the issue? Let's hope so.
What about the Math channel bug?
Maybe this will finally alleviate the code questions. It's from the
Re: Sniffing the Rigol's internal I2C bus thread.
Just because a code is not listed on the Riglol keygen, doesn't mean you can't use it!
Maybe some one knows how to get DSER added to the Riglol keygen list.
Here is the bit representation for the DS1000Z hack code:
The first column is always 'D' and the second column is always 'S'.
DS1000Z ECC private key: 0x6F1106DDA994DA
DSAB - 00011 10000 00000 00001 - Advanced Triggers
DSAC - 00011 10000 00000 00010 - Decoders
DSAE - 00011 10000 00000 00100 - 24M Memory
DSAJ - 00011 10000 00000 01000 - Recorder
DSBA - 00011 10000 00001 00000 - 500uV Vertical DO NOT USE!
DSEA - 00011 10000 00100 00000 - 100MHz
DSFR - 00011 10000 00101 01111 - All options DO NOT USE!
DSER - 00011 10000 00100 01111 - All options except 500uV/div USE THIS CODE!!!
The binary value assigned to each letter:
A = 00000 J = 01000 S = 10000 2 = 11000
B = 00001 K = 01001 T = 10001 3 = 11001
C = 00010 L = 01010 U = 10010 4 = 11010
D = 00011 M = 01011 V = 10011 5 = 11011
E = 00100 N = 01100 W = 10100 6 = 11100
F = 00101 P = 01101 X = 10101 7 = 11101
G = 00110 Q = 01110 Y = 10110 8 = 11110
H = 00111 R = 01111 Z = 10111 9 = 11111
Is 500uV/div a hardware limitation? Can't it be hacked too?
