TABLE,APPEND,1,80MHz,-30dBm,0deg,1us
# ramp power from 30dBm to 0dBm in 100us, then down again

Listing 8.8: Example using
TABLE,RAMP
to create an envelope.
Figure 8.5: Output generated by Listing 8.8 showing linear ramps in
amplitude.
The ramp functionality can also be applied to frequency or phase.
TABLE,RAMP
Listing 8.9 shows how multiple commands can be used
to execute a sequence of slow frequency ramps that can be watched
on a spectrum analyser. A graph of the corresponding frequency of
the RF over time is shown in Figure 8.6.
