Adjacent Channel Power—Sweep Time
[:SENSe]:ACP:SWEep:TIME <seconds>
[:SENSe]:ACP:SWEep:TIME?
Selects a specific sweep time used to measure the reference (carrier)
channel. If you increase the sweep time, you increase the length of the
time data captured and the number of points measured. You might
need to specify a specific sweep speed to accommodate a specific
condition in your transmitter. For example, you may have a burst signal
and need to measure an exact portion of the burst.
Selecting a specific sweep time may result in a long measurement time
since the resulting number of data points my not be the optimum 2
n
.
Use [:SENSe]:ACP:OFFSet:LIST:SWEep:TIME to set the number of
points used for measuring the offset channels for Basic and cdmaOne.
For cdma2000 and W-CDMA, this command sets the sweep time when
using the sweep mode. See [:SENSe]:ACP:SWEep:TYPE.
