Will this not only work if you have the Multi-frequency upgrade? See #978 where i started implementing this too

[qSaevar]

@jenshnielsen that could be. I'll see if we have a device without the upgrade for further testing/developing.

[jenshnielsen]

@qSaevar We have one without the upgrade so I can test that side but I do not have one with the upgrade. I never finished the other pr because of I couldn't test it probably.
But if we can split the testing between us that would be great. Feel free to steal the code from that pr to detect if the feature is enabled

[qSaevar]

@jenshnielsen I added a check, as in your PR, to see if MF is enabled. I can test this on a device later today.

[qSaevar]

@jenshnielsen I merged the code from PR 978 into this one and tested it on a device with MF enabled and it works. I do not have a device with out MF so I can not test that,

[jenshnielsen]

@qSaevar Thanks, I will test it on our device without mf. Hopefully tomorrow.

[jenshnielsen]

I have verified that this works correctly without the mf functionality.
@QCoDeS/core If anyone else wants a look please do. I have been involved in
writing some of this code originally so an independent review would be good

[astafan8]

The code looks correct. (but there is generally quite some room for refactoring and readability improvements.)

[qSaevar]

@astafan8 I addressed the comments you made.
