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... |

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? |
| 0xfede:
Attached you will find a quick and dirty measurement of a low baud rate application of the MRF89XA @868 MHZ. |
