Hi All,
Sorry for this old chestnut again, but I know things move on quickly, I'll try and provide as much information as possible.
I do have the most budget DSO available, (ha!) a 1988 Tek 2211 which is a fantastic 'scope, and it proudly wears the name 'Digital Storage Oscilloscope' on it, however it's erm...... Not up to standard in storage terms in 2016, the storage creates hilariously vague screen traces, which of course can not be 'stored' beyond leaving them infinitely on the screen. She's also a power-hungry big old lump of worktop space too! The ever-so-slightly creepy warning about radiation emblazoned on the stickers on the side of the unit also can scare a few
Budget £300 ($380USD/$480AUD).
- Speed, not a major issue, I rarely measure anything above 5MHz, never above 20Mhz, the Tek is good for 50MHz which I can always lift down off the shelf if I require anything 'faster'.
- Minimum of two inputs with variable timebases per channel
- Must be able to output captured waveforms as a file for inclusion in technical documents
- Must be able to be calibrated by a recognised calibration lab due to workplace technical standards
- Not majorly important, but some level of logic analysis is useful, but probably not viable at this pricepoint
I've looked a the Rigol, Keysight and Hantek offerings of various flavours, is there much between them (all similar prices) or are things all pretty similar at this pricepoint?
Is there a pressing reason say to buy the Rigol over a Hantek?
Sorry if this is an 'oft repeated question!
Cheers,
Ed.
