Siglent SDS1104X-E on Amazon US for $399 ($100 off) 28 Oct 2022
<< < (5/9) > >>
river:
according to  Honey app that tracks prices on things,  1104X-E  generally stays at $499  but  Amazon puts it on sale 20% off regularly enough to  $399, i.e.  Oct 11-12  Amazon Prime day.
The lowest I see it goes is  $375 or 25%  off on more rare days such as  the 2021  Black Friday as a limited "lightning sale."   

I called Siglent  in Ohio, USA  last week to ask them if  the 1104X-E  would also be on black Friday sale this Nov. 2022 year and thus I would wait for that since it's a significant drop. was told that  Amazon is the reseller and shipper - the sale is completely controlled by amazon and what they want to offer it for and if they will offer special black friday sale is all up to amazon.

It will probably go back to  $499  soon,  then "perhaps"  it might be $375  on Black Friday  or not and I did not want to wait for the cycle of $399 to come back around or have to stare at the screen all night Nov 26 black friday  waiting for the "lightning sale" of a possible $375.

See the Honey chart I posted above or just look at Honey or similar app for the tracking price trend over several months for the item.  I'm not saying to get honey since you lose your privacy,  it just helped me feel more comfortable spending the $399, since I can see it really only ever goes to at lowest $375 so I'm not going to get much better price.

Says it includes these items: SDS1104X-E, Quick Start, Calibration Certificate, 4 passive probes, USB cable
I am buying the   TP-link  TL-WN725N  also for $10.  is there anything else I should get ?

Some 24-36" BNC cables are handy for hooking up to signal sources. You will also want signals of some sort to look at, DC voltage is boring :) You might look into an inexpensive wave generator. Ebay is full of older analog gear that can be had cheaply if the shipping is not to great. Amazon or most any electronics surplus type store will have simple signal generators in the $30 range. You can also generate your own with a 555 timer chip or some jellybean components. The internet is loaded with circuits, but I would avoid the temptation of looking at your 120V 60 Hz wall voltage. It can be done safely if you know what you are doing, or it might blow a channel out of your scope if you don't. Our sponsor Dave has an excellent YouTube video titled How Not to Blowup Your Scope which is required watching for new scope users.

An Arduino can generate square waves of various frequencies with a single line of code:

tone(pin, frequency);

For starting out, the compensation signal on the front panel is a source of a signal.

It can generate a variety of (even arbitrary) waveforms with relatively little code.  Just don't expect great performance .. but if it's just to get familiar with a scope, it's all good.
