Thanks for the answers! I would like to buy a rigol 1054, but I have not the money now.. I have an electronics and computer engineer diploma and I would like to try electronics as a hobby now and maybe learn about how to repair electronic boards. I have 70-80 euro. I found a gw gos653 too. How it is compared to hp1740a? I live in Greece, so I search on ebay in Europe and auction sites in Greece.
I don't know the gos653, but if the price is the same and they both work, get the HP.
OTOH, if the GOS is much cheaper and you could use the money to get other
necessary equipment, that would be worth considering.
Be very aware that packing scopes for transport isn't easy. They often arrive with broken knobs, shattered tubes, or tubes with subtle internal damage. (See a 465's damaged tube in my .signature.) Inspecting a scope before purchase and avoiding transportation damage is strongly in favour of the HP1740.
So, for analog scope do you suggest me to go for a digital storage analog?
It is better to get a good analogue scope (HP1740/Tek465) than not have a scope.
The one time I
needed a storage scope in the past 25 years was when debugging the switchmode power supply of my 4
85. I had to observe the startup sequence, and I could only do that once every 6 hours! I used a 10MHz Analog Discovery - which I bought for its AWG, pattern generator and LA.
