Hi all,

I’m new to this group, a physicist by background but also new to using a spectrum analyser. Before I go and actually buy the Aursinc V0.3.1 model, I wanted to ask about how I might go about making measurements relevant to my research so I can be sure this is the best and most affordable approach.

To summarise, I am investigating resonance in coils driven at radio frequencies and high voltages and looking at the standing waves that result from certain coil configurations and wire lengths. To make it easier to show what I’m doing, I attach some graphics showing the circuit (without an output load), a typical coil configuration and an example of standing waves that show on a scope using a low-powered setup of 18V to the primary coil.

In particular, the queries I have are:

• Can I detect what frequencies are emanating from the coils by using the supplied aerial placed within say 50cm of the coils?
• What sort of attenuator would I need to cope with the high voltages and power in the secondary in particular?
• Are there any others known about how are doing this type of measurements?
• Will the tinySA-App work with Windows 10?

Thank you in advance for any help.
