Yep and i'm impressed by the FFT function, this is my first personal DSO that can be operated as a Spectrum analyzer with FFT, with a decent sensitivity.

If you have the time, some examples would be appreciated.

Q: Can it display the frequencies of the peaks in the FFT?

Also quite accurate with level, in attachment video with FFT of AM modulated signal : Fc 1MHz -56 dBm (-69dBV), AM 10KHz-30%.
No markers ?  :-//

Not that i know, these are the options available :

Our lecroy scopes haven´t got markers or even a table..
They expect you have eyes to see it and when you want to know the exact value, you can use cursors.
OK, for their prices you can´t expect more comfort, they cost with discount only 13000 or 14000 bucks each.

Surely it has markers and tools to manage them, have you found them yet ?
Heaps of this stuff in a 4ch X-E Siglent.
Just a wee snippet of what they have attached.

I can spot Heaps of spurious trapped in a Game Boy screen graphics, dunno what's worst.

What a horrible show !

Mapping Siglent's peak numbers to table indexes is a job in mental gymnastics if there's a few entries in the table. Hardly intuitive.

Rigol's "Table order" options seem sensible.

(even better would be to display the frequencies on the peaks themselves)

Show me a complex feature that is intuitive !

They can show tables of marker #, frequency and amplitude and there can be 10 and each one is adjustable, ON, OFF and in frequency.
Surely Rigol has this analyser type marker functionality too ?

Exactly. ;)
In this case Wavesurfer WS3024Z, Waverunner 9054, HDO6034A.
Last two got the same software.
Feeding in 1khz Sinewave from a GWInstek generator.
FFT as a math function, one pic shows the menu of the WS3024Z....That´s all, nothing else(it even didn´t got a split display function for FFT)
Second pic shows FFT from the HDO, no marker/peaks/table settings too.
But I must confess, I´ve forgot the "mighty" featureset of the HDO...In this case a spectrum analyzer function. 8)
And there are the markers/peaks/table....
But the "normal" FFT function didn´t have this.

It looks like the 'spectrum analyser' is a software option available for several Lecroy oscilloscope models.
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

IMHO all MAUI-based Lecroys have that (but probably needs a license).

It is a separate license. And not all have it. Most but not all.

Hi,

Yepp, depending on the performance 1 or 2 traces spectrum option avaible, starting with the 4000HD series, our Waverunner 9054 got this option also.
Offtopic:
Look at the vast amount of avaible options for the WR9000:

After 50 I stopped counting..

I had the opportunity to use some Lecroy scopes that came out around 2007-2008, apart windows boot stage I had a great feeling from them.

But there is a sore point, within few years all three instruments failed (total purchase cost around 35Keuro), the first was sent to service that (we discovered later) simply cleaned some connectors for a "honest" repair cost of about 2000 euros, the others, out of warranty, were treated in the same way by  myself ...

Nowadays non of those works anymore due to faulty screens or other HW problems, spares cost one arm and one leg, in conclusion the brand is now cancelled from the list.

Simply no Luck, here we got ones from 1993 on and still running/flawless through calibration going.
But one point is true: Exorbitant repair/inspection costs...

I guess not PC based, so a complete different object.

But one point is true: Exorbitant repair/inspection costs...

To say the least and consider that I was working in a multinational corporation without budget problem (at the time ...),

The last nail in the coffin for their supply was an instrument returned exactly in the very same state it left our lab, of course in the company of a salty invoice; the explanation provided by the service was so credible that someone got pissed off at serious level, then there was a brand change.

Those are the rebrands from Iwatsu 8) Japanese quality. My own Lecroy Wavepro 7200A also got a ridiculous amount of contact problems before it started to show signs of life. Then I needed to change a bunch of diodes on the front panel board because... the ones that where used where the wrong type and would fail over time.

Using a modern DSO as a a spectrum analyser is indeed a topic worth a sparate thread. The old scopes were limited by ADC S/N and usually low number of FFT points. With a 10/12 ADC and 1 M points FFT the dynamic range is actually not at all bad. The frequency range is a bit limited, but still not bad for something that comes (of could at last) as a software option. There is also an upside with usually better protection.

The spurious free dynamic range is usually limited by the linearity of the high impedance buffer and baseband vertical amplifier chain, and of course noise is limited by the high impedance buffer if a 1M input is used.

If someone could do a Two Tone IMD at 100KHz and 1MHz (or other frequencies)  and verify the Input Signal IMD with a quality SA (so we know the input signal ~ baseline IMD), this would be very beneficial IMO.

Any effort with the new HDO1000 and 4000 is greatly appreciated.

The benefit we see of these new higher resolution DSOs which can display Frequency Domain Data in somewhat "Real Time" is the reduction/elimination of a Dynamic Signal Analyzer needs for lower frequency high impedance needs.

These Frequency Domain functions (SA and Bode) can be very beneficial up to a few MHz (maybe 10s), with High Z inputs, all the benefits of the "Scope" probes, interfaces, and all in only one lab bench instrument (often bench lab space is limited). Above a few MHz then the usual Spectrum Analyzer (SA) and Network Analyzer (VNA) take over in the low Z 50/75 ohm RF domains.

Anyway YMMV of course!!

Best,

DHO....
Both series are renamed to this and I wonder what this could mean.
HDO is clear, high definition oscilloscope, but DHO....
Definition high oscilloscope..sounds silly.
Dumb high...Do not buy high...
Nevertheless I´ve played with the thoughts to get a DHO1074 just for curiosity and testing - After that, re-selling would be easy...
But you can´t get it easy here in germany.
Batronix don´t sell them for reasons, Conrad Electronic got them and could deliver inbetween 2 weeks.
But there´s a note, not for private customers....Why....
DHO4000 is no problem so what are rigol doing there...Won´t they sell the 1000s to the public..
Strange selling policy here.
