I started having the same problem with the Horizontal scale knob on my DS2000 after about 14 or 15 months of owning it. I sent it back (to the dealer) for knob replacement while I was abroad a month ago. It's fine again.
Hi,
question concerning the HORIZONTAL knob of the DS4000 series:
when I turn it fast the timebase sometimes jumps back or foward.
When turning the knob slower there's absolute no problem.
OK, good to know. But annoying to send it to the service. Does anybody know the part no. of these digital potentiometer? I mean, I expect it will happen in the future again and it's not difficult to change these parts. Last year our company sent an old Agilent scope to the service with the same issue and it cost about 500,-€.

Hi
Have You used the Key Test , see Pix below.
I had a RMA repair done on my DS2000 and received this note
Well, it was under warranty, so I only paid for shipping one-way. He offered to send me the part (or I could also just send him the encoder board already removed), but since I was leaving the country (and couldn't use the DSO), it wasn't worth my time to do the work myself to save € 30. I might be able to get the part number.

How often did you use your scope? Two hours a day? Well, many Rigols might have problems with encoders.
Just be aware that Hydrawerk is an Agilent Owner and strives to put down Rigol equipment,
I'm not sure why he nitpicks so much. Just like a chicken pecking the the red spot.

Some of the Rigols encoders are made of metal, I like it. At Agilent all of them are made of plastic. But I could not find any closer info on the manufacturer, or if they are mechanical or optical.
Hi,
Seeing that the "other" Rigol thread is mostly on the DS2000 and now the 1000 series I thought I'd post here instead.
Yesterday I applied MrKrabs edition of the 02.01.00.03 DS4000 firmware and it worked like a charm, all options stayed intact, thanks MrKrabs!
In another thread someone mentioned the decoders not operating on recorded frames, something that sounded a bit strange to me - say it isn't so I said to myself. Unfortunately that does seem to be the case (I only tested the RS232 decoder). I thought perhaps the frames had to be recorded with the decoder active but that doesn't work either - as soon as you press the record button the decoder stops updating. "Browsing" thru the recorded frames doesn't do anything with the decoded data on the screen, it just stays the way it was at the moment you pressed Record. Using the wavefor analysis function in order to "preview" the frames at the bottom of the screen the preview to the left of the current of frame somtimes distors badly and this appears to only happen when the decoder is on the screen.
Since the decoders appears to be software driven I really don't see the reason for them not being able to operate on recorded frames.
Don't know if it can be called a bug as I don't think I've seen it stated anywhere that it should work, still kind of a shame though.
Hello everyone.
Thank to Cybernet and MrKrabs.
My DS4024 model to full!
also i noticed a bug in this fw , i lost the abilty to set volts/div to 500uv not a huge deal but still it says parameters overrange and minimum is 1mv/div on my 4014 now
also i noticed a bug in this fw , i lost the abilty to set volts/div to 500uv not a huge deal but still it says parameters overrange and minimum is 1mv/div on my 4014 now
Why should there be a bug? Max. sensitivity of the DS4000 series is 1mV/DIV. It's not a DS2000 with 500µV/DIV.
im kinda surprised its 3 times the price i thought it did have 500uv , but I guess the Fw is working perfectly then , wonder why rigol took away that feature on a more expensive scope , interesting
Question: what you think which one is visible (not blind) time. 112 sampled points time or 700 sampled (but mainly not visible) points time.
I vote displayed sample size.
Ref: http://cdn.rohde-schwarz.com/dl_downloads/dl_application/application_notes/1er02/1ER02_1e.pdf
His sample sizes in his charts are incorrect at the lower time bases. When the Rigol displays '700*', it means it's sampling <= 700, which means at 2ns/div, it's sampling 112 points.
I would tend to agree with you - except in the case of segments, when you can zoom out to replay the full sample size.
Although Rohde-Schwarz calculates blind-time based on the full sample size - Agilent is the company that calculates based on displayed sample size.
Hey eveyone,
I'm trying to upgrade my DS4014.
I upgraded the firmware and got 00.02.01.00.03
Ultra sigma doesn't give me a large HEX. I' really lost, I'm jut a noob learning electronics.
Please help
Sam
