Generate a Frequency-Swept Signal
This procedure describes how to set up a signal at a constant power level that sweeps linearly from a start frequency to
a stop frequency over a set duration, then repeats the sweep. The signal will be set up with the following characteristics:
Start frequency: 1.00 GHz
Stop frequency: 2.00 GHz
Power level: 1.00 dBm
NOTE:
The example procedure in this section uses specific parameters to illustrate how to setup the 2500B. You can use
this procedure for real-life situations by simply changing the parameters to fit your needs.
