Agilent E4406A Vector Signal Analyser
davorin:
Trying to use the E4406A with the software to demodulate a FSK 868MHz Signal coming from a Microchip MiWi transmitter...
Only think I know is the bit rate of 20kBits/sec of the Transmitter, and that it transmits slightly below 868MHz.
The Microchip datasheet doesn't mention which FSK it actually uses, but as 4 bits are used to generate the frequency shifting I assume FSK16.
Still can't get any meaningful readings out of the VSA software...
PA0PBZ:
I think MiWi supports frequency hopping, so good luck following that on the VSA :)
Also, where did you get the 20 Kbps from, what chip are we talking about?
Can you see any carrier on the VSA?
davorin:
It's a MRF89XA transceiver....but isn't FSK the same as frequency hopping?
The 20kbs is programmed in software...
Yes the carrier can be seen clearly..here two transceivers communicating:
davorin:
Maybe another question...what are you using the E4406A for?

Attached you will find a quick and dirty measurement of a low baud rate application of the MRF89XA @868 MHZ.
