REL #44 Power measurements – Scope or dedicated? Siglent SDS2000X Plus vs. GW INSTEK GPM-8310
How does a scope with Power Analysis software compare to a dedicated power meter? In this video, I compare the Siglent SDS2000X Plus oscilloscope plus its SDS2000XP-PA software option with the dedicated GW INSTEK GPM-8310 Power Meter.
While the Siglent has interesting functions, its software/firmware is a mixed bag, and some things do not seem to work as well as expected...
