Thanks, that makes sense. Here's what I was looking at previously (not exactly a datasheet)...

I would like to understand why servo motors often state they are a "12V servo" but then in the datasheet they will refer to tests and torque ratings at 14V? I'm assuming 14V is chosen due to common lipo battery voltages, but then why call it a 12V servo motor?

Thats a good point. Aside from that, does that system look to be ok if I connect the isolated ground to the chassis and earth?

I am currently working on a high power class E amplifier which will sit inside a metal enclosure. It is powered by two power supplies - both are isolated but one of the power supplies is mounted in the same enclosure. The power supply itself is in a metal case and that case is connected to...

yeah I just checked the maximum insertion loss of the power meter and used that. Also it's for an inductively coupled plasma source :)

Thanks all, I think the correct way of thinking is to just to assume 1W will be lost due to the 0.1dB insertion lost, I was definitely overthinking it. Cheers

Thanks for all the answers. I'm planning on using a diamond SX100 power meter for measuring the power and SWR of a simple 13.56MHz sine wave, no data transfer or anything involved. There don't seem to be any datasheets on that power meter either. I more meant what is the equivalent circuit i...

I'm starting to get into RF electronics, and an upcoming project involves the use of a power meter / SWR meter. How do we model a power meter in terms of an equivalent circuit? i.e. is it just another impedance? or a transformer? or does it not effect the circuit at all, so we just don't include...

Thankyou, that makes a lot of sense. So I was correct in assuming that one connector has positive reactance and the other connector has negative reactance so that when the are connected together, they cancel impedance and are essentially invisible to any signals?

I am just a bit confused as to how impedance is matched with RF connectors such as type-N or BNC connectors. I know Coaxial cabling and RF connectors come in common impedance ratings like 50 or 75 ohm but how is this all matched properly? For example many people have told me that when using...

Thankyou both, exact answers I needed, really appreciate it!

I am trying to calculate the correct component values to use in a simple series LC filter, however I am not sure which value of resistance is to be included in these equations. When talking about a series LC filter, is the resistance required for calculating q factor the resistance of the...

Finally found an answer! http://www.programmablepower.com/blog/external-capacitor-prevents-problems-with-high-ripple-current-loads/ I am just going to assume my RFC has to be large enough to reduce the ripple current and voltage bellow the rated ripple current and voltage. Thanks for your help.

I'm unsure on the specifics but I was more just hoping someone knew the name of the parameter that details the maximum allowable oscillations at the output. I guess the answer to the following question will help me understand: why is it common to block AC frequencies from reaching the output...

Is there some common parameter for DC power supplies that provides the maximum oscillation amplitude allowable at the output? For some context - I would like to generate an oscillating signal powered by a DC power supply, but to prevent most of the oscillations reaching the DC supply I am going...
