Power supply of the Spectran V6 ECO
Hi,
question regarding the power supply of the Spectran V6 ECO :
in this post => https://v6-forum.aaronia.de/forum/topic/ucb-c-power-to-pigtail-cable/#postid-1624 . It was about the Spectran V6Plus, mm_dev indicated => "For full functionality you need to provide USB-PD 3.0 9V @ 3A."
Dixit datasheets :
- the V6 Eco has a power consumption of 10W
- so, lower than the 15W of the V6 Plus
Question 1. : what's the power supply requirement of the V6 Eco to get "full functionalities" (thru the USB connector) ?
Voltage = 5V , as simple as that ? and given power consumption = 10W => a 5V/2A PS and the V6 Eco runs fine.
Or, as you mention a USB-PD connection => voltage is >5V ? If V>5VDC, what is it ?
Question 2 : power from the PC is based on SMPS (=noisy).
Did you test a linear PS instead of "standard USB link" to power the unit ? If yes, does a cleaner PS enhance the perf of the device ?
If not tested, do you recommend a clean (linear) PS for better perfs ?
Thanks for feedback.

Depending on installed hardware options and operation mode the ECO needs 10W (Rx only, TCXO, no GPS) to 14W (Rx & Tx running, OCXO warming up, GPS) so in any case you should make sure to offer the full 15W (5V with 3A) or a real PD (which offers higher voltage e.g. 9V).

The USB PD works fine. Charging the ECO with optional (cleaner) supplies might offer some slight noise reduction at very high FFT rates (and depending on frequency) but nothing you will see in regular operation mode.
