Default Best osciloscope to 1000$

By your opinion , what is the best scope for 1000$(new), by precision and range of measurment capability and offcourse by overall quality.

I know that Tektronix , Fluke .....are exellent , but in most cases , expensive too.

Thanks for your replays

If you need it for audio only buy a cheaper used one!

I plan to create a dual channel dso, 60MHs/sec, ccontrolled via printerport. Based on the 8bit a/d converter ADS 830 E. Cost will be lower than 100,- €, maybe lower than 100,-$.

I am not Dr. of electronics , but I need reliable equipment for repairs and tweaks on audio components(sometimes video), which I do in my home.
Next instrument I need is precise LCR meter and function generator(probably DIY project).

Osciloscope is very important peace of measure equipment .

Hi,

just 3 weeks ago I received a Tektronix TDS2002 (about 1400 Euro)... It is a Digital Storage Osciloscope, 1GHz sample freq.. with FFT, averaging, waveform memory etc etc... it is nice, small, but NOT for analog / audio type of measurements ... I would never consider it to buy it for my audio hobby .. my cheapy 20MHz, build in sine-generator, 500 euro Voltcraft scope is better... the Tektronix TDS2002 goes down to 2mV, my Voltcraft 622FG goes down to 0.5mV .. which can be handy! The old second hand philips scopes analog/dig hybrids are very nice..

For building a function generator i can give you some max 038. I have more then i need. Or you order some samples of this chip from maxim-dallas.

There's a nice smd-apllication from elektor which takes most out of this chip. I can mail you if i'm back home.

I also have one unused xr2206, bought for a similar project but never build. This chip may be better for sine-waves (not really sure).

This link gives you a simple function generator: David Jone's function generator

and you can take this for a lowcost frequency display from the same author: Frequency Counter

For max038 drop me a line. I have both, smd- and dip-version.

Thanks for the links

tschrama , is the low voltage range only factor why is old analog scope better than new digital Tektronix for audio purposes , or there is some other factors which i don´t see?

I am little suspicious about scound hand.

What about , Hameg scopes?

Gasho, most DSOs sport 8-bit ADCs, so this is limited resolution for precise analog measurements, especially in the audio field.

Now if you want to be able to analyze transients, a DSO is a must have. You won't be able to do this with an analog oscilloscope.

eBay is a nice place to find good deals. The ideal situation would be to make sure that the seller has a decently recent calibration certificate for the scope you are interested in.
