True 1

Specifies that the BT Generation computes the headroom value based on the peak power of the signal. The BT Generation assumes that the generated signal average power is 0 dB. The BT Generation adds a power margin of 1.5 dB to the peak power to give some room for the filters in the NI RF vector signal generator. You can read the value of the computed headroom using the Actual Headroom property.
