VSG packet burst

Up and running in less than a minute. So far, fantastic.

I need to generate packets though, not continuous transmissions.

How can I do this ?

1Mbps, 376bits, GFSK +/-420kHz BTb 0.6 1 376bit packet every say, 100ms?

Thanks for a great product.

Hi Paul,

Thank you for the feedback.

Currently through the standard software interface it is only possible to set a period with the ARB setup. This may not be practical for you unless you know how to generate your waveform though. With the ARB setup, you can select a period for your waveform up to 64k samples. So the period length would be limited by the sample rate. We have had another request for this functionality, so I believe we will be adding the period parameter to the standard modulation setup in the near future.

Thank you for the reply.

One more question, Modulation depth has no units. What do I need to set this to for say, a +/-325kHz DOM ?

Paul

Hello Paul,

The modulation depth for FSK is the ratio of the frequency deviation to modulation frequency. A more common term for it is modulation index.

e.g. If modulation depth is set to 0.5, then the frequency deviation will be 1/2 of the symbol rate frequency.
