Yep.? I had done that up to step 5.? Every port I tried said "The port has been opened by another application..."? I guess I'll try one and see what happens.? Does the tinySA care what com port is

That's a good point. IIRC this is a symptom of incorrect firmware. Firmware for the Ultra resides here: http://athome.kaashoek.com/tinySA4/DFU/ For the TinySA classic it is here:

You sure you have the right software?

Roger, Yes, I am using that guide.

To change the COM port number of a serial device in Device Manager, complete the following: * Open the Device Manager by pressing the *Windows Key* + *R*. Type “devmgmt.msc” and press *Enter*. *

Thanks. I checked out the attenuator and it shows flat green line, so good I assume. Just need to source the RF switch now. Cheers

I've tried to connect the VDD and BOOOT0 and reinstall the firmware and it continues to be a white screen.

I'm trying not to get drawn into this but…. Just because a unit has an ESD protected input, does not mean it suddenly becomes totally immune to ESD or input Voltage overload damage. It just gets a

Especially so when (AFAIK) the person who doesn’t know what he doesn’t know hasn’t yet got in his possession an example of the actual instrument that is being discussed! Often “less is more”
