How can i interface labview to Two way Radio freq (452 MHZ, 450 MHZ) transreceiver for point to point communication?

[yog]

Transreceiver specications are nearabout
point a to point b message 452 MHZ
and point b to point a message 457 MHZ
transmit power 2 watt
Transmitting 16 bit data

You would need a PXI-5660 for input and PXI-5670 for output. Since these are the only RF analyzers and generators that can handle it.

The PXI-5660 RF Signal Analyzer is a PXI-based hardware product from National Instruments that can receive signals from 9 kHz to 2.7 GHz with a 1 W max input power. If you transmit at 2W and after reaching the antenna connected to the 5660 the power is > 1W (+30 dBm), you will need an attenuator in front of the 5660 to bring the signal level down to a point which the 5660 can handle.

As for the Tx side, you can Tx with the PXI-5670 RF Vector Signal Generator at a max output power of +13 dBm, which is ~20 mW. You would need an RF amplifier for sure between the PXI-5670 output and the ensuing antenna.

In both cases, the devices come with software to control them that are LabVIEW-based and quite easy to use. If you already have RF Tx and RX hardware, they
probably have LabVIEW drivers, or some other interface with which LabVIEW can interact with. I recommend contacting NI at 1-800-IEEE-488 and asking for an internal sales representative to discuss your app with. Or, you can post more details here and I can definitely answer your questions.
