Default Choice of oscilliscope

Tektronix DPO2012 or Agilent DSOX2012A is better if price does not put in the equation.

It seen better than the above 2 model, the DS2XXX most sensitive of 500uV/div is a software zoom mode or actual a hardware feature?

I have the Agilent DSOX2004A with WaveGen after a life time of Tektronix. If it were stolen I would go straigh out and buy another one.

Don't know what you're needs are but I'm a avid tinkerer and recently picked up an OWON DS8102. I'ts been an excellent tool on my bench. Cost about CAD $450.

For analog signals, a cathode ray style scope is your best bet. Modern Digital scopes (even expensive ones) tend to have too much noise from switch mode power supplies which can add artifacts to the display

the "cost no object" leading edge for moderate frequency (few 100s MHz) analog today is actually 12 bit digital 'scopes

most digital scopes use 8 bit converters, only add a bit of resolution with averaging

some do still have wet dreams over mcp intensifier display analog from decades ago

for just extended audio measurement - not parasitic output Q oscillation - 18-16 bit 400 kHz-4 MHz monolithic ADC exist

Happy with Rigol DS2000 series too. First impressions are its a fast computing well thought out DSO. Just pressing "auto" is enough to demonstrate its speed. Operating satisfaction is up a league from the previous 1000 series. Especially the dedicated metrics menu to the left is a boon. 8 inch screen real estate and 800x480 resolution plus shades grading give a sense of luxury. Soft buttons green backlight could be stronger its only noticed when there is strong light direct on. The screen is fine as long as it is viewed at a soft down looking angle. Above eye level positioning of the scope darkens it out. Better avoid such positioning if you can rearrange the bench gear. The fan is rather too noticeable in silent surroundings although heavier in tone and lower in SPL than in the 1000 series. Its just a close pass under ''nuisance'' level for me. The probes are short and agile enough to handle. Their speed looks adequate. Must push to lock the hook nose bits until a click is heard, else they will slip off easily. Not different than those in the small series in that respect. The noise is low with the averaging method or the Hi Res mode on. About 100uV PK-PK @ 500uV vertical. Takes 20MHZ BWL for the averaging method to beat the Hi Res mode in 40uV PK-PK. In full BW they are equal. I got it form Peter of Silcon Electronics A Small Czech company with same pricing and free shipping, phenomenal pre-sales and after sales support though. Recommended for anybody buying Rigol gear in the EU.
