Siglent SPD3000X-E Datasheet

I am an amateur radio and electronics enthusiast, who likes building RF circuits. I bought The Siglent SPD3303X-E for use on my workbench, replacing a much cheaper PSU which I found to be electrically noisy and difficult to set precisely.
I am absolutely delighted with my new power supply. It cost a little more than an amateur would normally spend on such a device but it is such a joy to use, being easy to set and the display being easy to read. It is not my first piece of test equipment bought from Telonic and it won’t be my last!
I am most impressed with it and I can highly recommend it.

Needed to develop and test a high-gain pre-amp and power amp combination to drive a hearing aid induction loop system for a relative, my previous (Chinese switching) PSU was quite noisy with switching spikes and ripple – so I bit the bullet and bought a Siglent SPD3303X-E.
.
Am absolutely delighted with it, superb control of voltage and current (the current limiter works well -don’t ask) and the noise is negligible (my Siglent ‘scope can barely see it).
.
Am impressed and very pleased, although more than I wanted to pay, it seems you do get what you pay for – highly recommended.
