    Is it possible to create a GPS signal with VSG25A ?

    Unfortunately, no. Due to the small pattern buffer, a test GPS signal cannot be generated.
    With our VSG60A (coming later this year), you can play very long patterns. If you have software that generates a GPS test signal, the VSG60A could play it.

    So, the VSG software from signal hound will not have preprogrammed GPS signal generation, right?

    That is correct Dhivagar.

    Is this same for a Bluetooth signal also ?
    Can you suggest me which software is used to generate a test Bluetooth and gps signal ?

    I am not familiar with software that can be used to generate these waveforms.

    I found one video for this GPS generation application from keysight
    https://www.youtube.com/watch?v=2qv7vr8n_CQ

    Can we follow this same procedure with our VSG60A or else is there any possibilities to generate a GPS signal using Matlab and play with VSG60A?

    Also, the signal strength of GPS signals were very low upto -120dBm since our VSG cannot generate such low signals, how this is possible?

    Dhivagar,

    I’m not familiar with GPS, but I believe the sample rate needed is 5MS/s or less, so I believe the VSG60A could generate a GPS signal if you used other software to generate the GPS waveform. We have no plans to create such a software at this time.

    Regards,
    Andrew
