New Zoyi multimeter+oscilloscopes - ZT-70xS, up to 50MHz/250MSps (nov 2022)

[SlCKB0Y]

Received the ZT-703S+ today, seems like there is not much changed internally between these models. My original ZT-703S has PCB revision 2.2 and this one has 2.5. Can't seem to find any major component differences. Seems like the difference is mostly in software and the color of the housing.

The flagship features of the ZT-703S+ appear to be a far more capable signal generator. It’s now a user selectable amplitude (0.5v - 5v) with a frequency up to 10Mhz! (Up from a 500Khz fixed at 2.5v).

Isn’t this like 20x the frequency range of the ZT-703S? You are thinking this is just being done in software?

So the 706S is available here (https://www.aliexpress.com/item/1005012105196323.html), and the 703S+ available here (https://www.aliexpress.com/item/1005011775300304.html).

And to get this straight, the 703S+ is a 703S with an improved signal generator, and the 706S has the improved DMM, but the two are mutually exclusive?

Lol

The 706 carries the improved signal gen from the 703S+ according to specs.

So we have 703S (25K DMM - toy sig gen) / 703S+ (25K DMM - capable sig gen) / 706S (66K DMM, capable sig gen).
Identical oscilloscope hardware on all three it seems.

Weird lineup.

At the rate these are being iterated on I'd hold out for the 707S with a 80MHz scope , 706S is quite tempting though, is there any info as to how many bits the siggen DAC is? I'd be assuming 8, could save me buying a dedicated siggen if it's 12 though.

Hello! Please help me with a problem with my zt-703s device. It worked fine, I used it to measure 2032 batteries, and the firmware was updated. One day, I turned it on and it started up as usual, using the last mode I used, which was the constant power mode. Now, it beeps once a second and doesn't respond to buttons (only in F1+PWR mode do the buttons work), but it's still possible to take measurements in this mode. I tried formatting the flash drive and updating the firmware, but that didn't help. What should I do?

[tunk]

Probably won't work, take out the battery for maybe 5-10 minutes.

I've bought my 703S for 46$, but 706s is 105$ at start !! WHY !!??

They raised all prices significantly since last year (or even early this year).

Could be worse.

So it seems that Zoyi is starting to follow in FNIRSI’s footsteps and instead of improving their previous device, they are releasing another one? Their multimeters turn out great, but they seem to have trouble making a good oscilloscope. I guess they are cutting costs too much and not using an FPGA, which is why there are issues like slow performance and artifacts/triggering problems.

And looks like it's not so cheap anymore.

At this point we wait for someone to do a teardown of the new ZT706s to understand what direction the company has taken

Seems there's a new v1.8 firmware?

Inside this packet is the already known ZOYI-703S-FW-V1612.ZTK version

Zoyi sent me the ZT-706S to review, video will be published on Tuesday/Wednesday this week.

No, that's the date, the 8th of January.

There is no new firmware release.

It's ready... I guess.
