<p>I notified Tequipment of the report of a power-on transient in
the Rigol DP711. They responded they thought there was a firmware
update to do with this but also immediately contacted Rigol. RIgol
quickly responded, confirming there is still a turn on transient
but it's limited to 1.7 volts. I'd decided for my applications
this won't affect me and was going to order one, but then noticed
it takes three firmware options to get full functionality and that
made the price unreasonable to me for a single channel supply.
What's extremely attractive about this PS is that it offers an
SCPI interface via a simple serial interface. So you can send
simple commands to control the supply and get its current settings
and it's actual output voltage and current, etc without complex
software. I'm going with a different choice from Tequipment and if
it pans out I'll share about it if there is any interest.</p>

I'd had my eye on a single channel Rigol power supply for some
time because with an inexpensive add-on it can be made to have
1mA/1mV resolution and it seems to have a straight forward
interface for program control. I was considering this to be a
Black Friday impulse buy (even though it isn't discounted) when I
happened to notice a single review of this power supply that
canceled my plan. It remains to be seen if this is a one in a
zillion production outlier or one of the supplies that has these
transients as a mis-feature, but I'm not in a hurry to find out.<br>
