Pros
- Very low output noise for audio, RF and sensor work
- Sets voltage and current in 1 mV and 1 mA steps
- Remote sense holds the set voltage at the load, not just at the terminals
- Scriptable over USB or the network for automated tests
Cons
- Only 150 W, so it costs a lot per watt
- Over-voltage and over-current limits are not listed on the datasheet
