Hi Linda, Do you mean "sending 0 in between" or do you mean "switch transmission on some SDR device on and off"?
First case: multiply with a (threshold(sawtooth from signal source)) Second case: see the gr-uhd examples on how to do bursty transmissions, if a USRP is what we're talking about! If possible, when asking the mailing list, give enough context so that we can unambigously understand what you're asking about!
