Sweep Time
With the RMS detector, a longer sweep time increases the stability of the measure-

on page 142.
The sweep time can be set via the softkey in the "Ch Power" menu and is identical to
the general setting in the "Sweep" configuration dialog box.

5.3.4.2 Channel Setup
The "Channel Settings" tab in the "ACLR Setup" dialog box provides all the channel
settings to configure the channel power or ACLR measurement. You can define the
channel settings for all channels, independent of the defined number of used Tx or
adjacent channels (see "Number of Channels (Tx, ADJ)" on page 152).
For details on setting up channels, see chapter 5.3.6.2, "How to Set up the Channels",
on page 173.
In addition to the specific channel settings, the general settings "Standard"
on page 150 and "Number of Channels (Tx, ADJ)" on page 152 are also available in
this tab.
