both channels if this soft key is active, If a dual-channel measurement is
selected, both channels are automatically acti v ated,
performed on Channel 1 only,
performed on Channel 2 enly,
between two signals as a function of the time shift between them. Because
it is a dual,channel measurement, both channels are activated when it is

ures the system's input, and Channel 2 measures its output Because this is
a dual,channel measurement, both channels are activated when it is
selected,
tude is distributed between its minimum and maximum values, It is a single,
channel measurement, and can be performed independently on both
channels in the linear resolution mode, The accuracy and resolution of the
histogram is dependent on frequency span, recor d length and number of
averages,
