content: There is a wide range of scopes in that entry level budget, it will depend on your specific requirements as there is no single best scope or obvious "winner". Consider other manufacturers such asGW Instek (MSO-2000E, MDO-2000E)Rohde & Schwarz (RTB2000)Siglent (SDS2000X)

content: Hello,for that price tag it really depends on your individual needs.2 / 4 / 8 Channels8 / 12 / 16 Bit resolution of the ADCI am happy user of a PicoScope 5444A.https://www.reichelt.de/USB-Oscilloscopes/PS-5444A/3/index.html?ACTION=3&GROUPID=4055&ARTICLE=146219&OFFSET=100&But I would not recomend it to someone who measures mains voltages.(largest range +/-20V so even with a standard 10:1 probe you cannot measure the 230V so you will need a special probe).with best regardsAndreas

content: Quote from: Someone on August 28, 2017, 01:46:25 amI don't like RTB2000,because it's sluggish and laggy.I need something of very smooth,something which can allow me to develop my digital and analog electronics stuff.Im thinking about Keysight and Le Croy,because i heard about them as the fastest scope on the market,especially Keysight scopes with their ultra-powerful asic's.

content: Quote from: Free_WiFi on August 28, 2017, 09:21:30 amKeysight has short memory and Lecroy's Wavesurfer 3000 has no peak detect. Besides that both are way outside your budget if you want to have a reasonable bandwidth, digital inputs and protocol decoding.

content: Quote from: Free_WiFi on August 28, 2017, 10:14:36 amI'd go for a GW Instek MSO2000AE series because it has a lot of features and very mature firmware. I have a GW Instek GDS-2204E (which runs exactly the same firmware as the MSO2000E) myself and I'm pretty happy with it. If I want something which is better I'd have to spend 8k euro or more on a new scope but I'd likely still end up compromising on memory depth, input filtering, FFT length and processing speed.

content: In our modern era of nano-tecnology the digital scopes are still expensive more then 1 kidney!(and they are also not yet perfect for their price)Im really mad on this,we are able to make microcircuits,cpu's etc in tiny factories,because it's not hard anymore like it was 50 years ago.....I will check up my economical situation in the future to get 1 decent scope for all my needs,but if something goes wrong then i just get 1 Keysight X1000.

content: Quote from: Free_WiFi on August 28, 2017, 12:30:34 pmYou have a surprisingly large budget for your first scope..........as it's your first my advice would be to start with something much lower priced to find what you need and want from a DSO. Check the specs of SDS1202X-E, not just a quick look, download the datasheet and use it as a yardstick to compare all against.Off now to bed.

content: Quote from: tautech on August 28, 2017, 12:48:16 pmBut if that low priced entry level scope doesn't come close to what he needs, it would be a waste of time and money.Starting a discussion of use patterns and what is available in the market will likely get him a reasonable first scope that will be useful to him for the long term.And the discussion brings up important factors that others might not have thought of but can learn from.

content: I agree. It is often better to buy the best tool you can afford. For example: I used to own a cheap Black&Decker cordless screwdriver. I used it a lot but when it broke down (worn out) I got a Makita and the latter is just so much better (more convenient to use) that I wished that I bought the Makita in the first place.

content: Im not really in logic sniffing;so maybe the keysight series x1000 could be the perfect first dso for meor the SDS1202X-E remains the best bang per buck?

content: Quote from: Tom45 on August 28, 2017, 02:01:01 pmAgreed but I doubt it will fall short of expectations.As it's Free_WiFi's first scope a cheap unit is a viable choice into the world of scopes and for all but advanced use it's likely he won't change it until he's grown out of it or there's something better in the market than current offerings.QuoteYep, but we haven't got a lot to go on as yet.Again, a first scope is not always the last but an informed choice for the first and moving forward with knowledge gained of scopes and knowledge of electronics where requirements can and do change as skills develop.These days we don't need to spend heaps to get very reasonable gear and the money saved can then be redirected to other goodies we want to acquire.

content: Quote from: Free_WiFi on August 28, 2017, 07:13:24 pmYou might also consider the SDS1202X (not -E). It has a larger display and is quite good for the money.

content: Quote from: Tom45 on August 28, 2017, 09:34:14 pmI like both for different reasons.X:Larger display....better for older eyes.50inputs.X+:AWG and MSOX-EThere's some new features added to the UI, the user definable Default is my fav......you know how you can get far away from basic settings with ordinary use, well once you've set this up (10 sec), just a stab on the Default button and you can be back to the start settings you commonly use. Real handy if you use BNC connection from time to time, instead of changing the channel inputs from 1x to 10x (normal usage), just hit the button.Mentioned here:https://www.eevblog.com/forum/testgear/new-siglent-sds1000x-e-oscilloscope-based-on-xilinx-zynq-7000-soc-architecture/msg1196101/#msg1196101The X-E FFT is better than X models.The smaller display I thought I wouldn't like too much but the colours used and contrasts make it quite good for a small scope.PNG default file save.Small and light package form factor.That's what just comes to mind........
