Hi. I have here a brand new R&S NGE100 from work. My colleague gave it to me to verify. He said that the voltage is slowly jumping around.. I can confirm this, look at the chart I recorded. Anyboy knows whats going on here? Should I send it back? |
| Alex P:
Is it set to supply 4V? And what is the current? You don't have EasyArb or EasyRamp enabled? |
| justanothername:
Supply is set to 4V. No current (directly into the multimeter). No arb or anything. |
| Cloud:
What if you try to load it up a bit and measure then? |

Ok I connected a 390R ceramic resistor to the channel and the jumpy behavior seems to go away. But look at the charts! It is a really terrible noisy and drifty power supply! with 11mA@4V it has a range of 38.7mV!! This PSU has a price of over 1000€! The jumpy drifting on light loads is also unaceptable if you ask me! What should I do? Do you think this device is faulty? |
