As I'm having to build a table-top-workshop here from scratch (can't denude my workshop back in the UK), I've been trying out some of the nice USB-based tools you can now get.
Just received an Analog Discovery 2 unit http://store.digilentinc.com/analog-disc...er-supply/ - Farnell have them for about GBP 220 http://uk.farnell.com/digilent/410-321/o...dp/2528523
This is an interesting bit of kit - it's a cooperation between Analog Devices (who do all the signal conditioning and interfacing) and Xilinx, who do the logic, but put together by Digilent, who sell Xilinx development systems... Initially just a reference design, i.e. a technical paper, they realised that they had something pretty neat on their hands, so made it a product.
The design has turned into a really cool bit of kit at a very acceptable price - a full design rationale is available as are all the schematics etc. in the reference manual (also on the Farnell page). Its a really nice unit... Two programmable supplies, 2 waveform generator channels, 16 logic channels. Lots of analog too. 14-bit A/D/A as well, not the usual 12-bit...
I also have the probe expansion board - just sooooooo cute!

- Two-channel USB digital oscilloscope (1MΩ, ±25V, differential, 14-bit, 100MS/s, 30MHz+ bandwidth - with the Analog Discovery BNC Adapter Board)
- Two-channel arbitrary function generator (±5V, 14-bit, 100MS/s, 12MHz+ bandwidth - with the Analog Discovery BNC Adapter Board)
- Stereo audio amplifier to drive external headphones or speakers with replicated AWG signals
- 16-channel digital logic analyzer (3.3V CMOS and 1.8V or 5V tolerant, 100MS/s)
- 16-channel pattern generator (3.3V CMOS, 100MS/s)
- 16-channel virtual digital I/O including buttons, switches, and LEDs – perfect for logic training applications
- Two input/output digital trigger signals for linking multiple instruments (3.3V CMOS)
- Single channel voltmeter (AC, DC, ±25V)
- Network analyzer – Bode, Nyquist, Nichols transfer diagrams of a circuit. Range: 1Hz to 10MHz
- Spectrum Analyzer – power spectrum and spectral measurements (noise floor, SFDR, SNR, THD, etc.)
- Digital Bus Analyzers (SPI, I²C, UART, Parallel)
- Two programmable power supplies (0…+5V , 0…-5V). The maximum available output current and power depend on the Analog Discovery 2 powering choice:
...250mW max for each supply or 500mW total when powered through USB
...2.1W max for each supply when powered by an auxiliary supply. 700mA maximum current for each supply.
