Nope, not only is there not new firmware to fix the multiple bugs still present in my relatively new SHS806 Scope, but now it's not even listed under handheld scopes. If that's the level of support that one can expect from Siglent I won't be buying further devices from them.

@ "Taking a screenshot with "SDS 1202X-E" using the blue Print button that saves the file to USB pen drive."
Is it a known issue that the newest FW 1.3.26 makes the scope to freeze completely and therefore useless, when trying to save an image more than once?No it is not a known issue.

At times scope would freeze every time i try unless i boot with USB removed. Then it will work every time but not forever. It will take some time before it starts acting up again.
Just today (again when i needed it the most) it started acting up.
Tried different USB drive, same problem. But it went away as soon as i booted WITHOUT USB drive inserted.
Something in the circuit that is not working correctly. I think if i let it sit for few hrs, it will come back.
I cannot hope this will go away because i know for a fact it will come back the worst moment possible.
Thanks, some more info please.
Firmware version ?
USB stick properties ? Stick size and format type and cluster size.

USB drive does not matter, it will behave the same way regardless of the drive or how its formated.
I confirmed.
Formatting to FAT32 with 4096bits cluster size makes the problem go away.
It is a scope issue, firmware to be specific, unable to handle different drives. Typical Chinese device problem.
I've seen this on security NVR systems. USB device wont work when booted with it plugged in, but will work if you unplug and plug it back in.
Also something is wrong with this forum.
When i click POST, it takes me somewhere else other then to a place where i just posted my reply.
It makes me confused and i go back to post again and again but it will not post anymore.
This is very strange.
Every forum in the world directs you to where you just posted.
AFAIK Siglent Cal kits are made by Rosenberger as many of their HF coax cables are.
They are not supplied with any characterization data.

Dang, that’s what I figured. Thanks! By any chance do you know if it’d be possible to pull the kit data off of the SVA? I’ve seen a vnacalkit directory on the machine but it seems to not have everything in it to cover all the kits on the machine and the data files that are there only go up to 1.5GHz so I feel like I’m not looking at the correct things.

Each and every Cal can be saved internally to be recalled when needed for say a common cable/adapter setup you might use. They can all be named as you like.
If you do a Cal on the full sweep of the instrument that's what will be saved and a narrower sweep will only save that frequency settings. SVA have increased the data/sweep points from a previous max of 751 to 10001 although default is still just 200. We only change the points for speed vs accuracy depending on what we need.
i need to know the part types of the four SOT23 devices,
is the SPD3303X designed specially poor ? when it comes to ESD or other unwanted unlucky hight voltage events
between the DC - AC - Chassis ??
yesterday i killed BOTH my SPD3303X due to an arc over event in the lab to mains.
and i mean it took me 9hrs tracking and replacing parts in them, that much was found dead so far,
List : TL072 shorted, 7815 shorted, Ethernet ic shorted, IRFP150 shorted, IC inside fan shorted,
4k7 in gate drive, and a 100nF cap in gatedrive shorted,
small signal pnp for gatedrive shorted, 6.3A fuses blown,
last thing to solve : ch3 output not going on, complex logic trying to trace the idea behind all the transistors, diodes and zeners involved in this,
one reason for it to be very complex is the LED control, it is a 2 pin led, 2 color, red green,
the green do go on when i push output enable, so signal from optocoupler is there, however no gate drive, to power board,
and the power board is confirmed working (the other unit works now 100%, so i got one to compare with)
any one with a schematic snip of the ch3 logic ?
picture attached, i need to know the part types of the four SOT23 devices,
otherwise i need to remove them one by one from my working unit to prove their function,
and then add what ever i feel fit the feature
>Silkscreen Pt#'s please.
PCB is called SDY8.007.038H
SPD3303_150700
QC1 = unknown sot23, marking 2A and a 6 or 9 laying down
QC2 = QC3 = QC5 = QC6 = unknown sot23, marking 1AM>
cant find QC4 so that number maybe is not in use
UC5 = TL431 this one works
UC3 = TL072 ok changed that one
UC4 = TL072 did not change it yet
DC3,DC4,DC6 unknown diode
ZD702 unknown zener
ZD703 unknown zener
