ENR Mode Spot Table
You can enter ENR data for the
noise source you are using as a table of values or as a
single spot value. The values held in the table can be used
for measurements at a range of frequencies as well as at a
fixed frequency.
The single spot value is used either for measurements at a
single frequency, or for measurements across a range of
frequencies that is narrow enough such that the ENR value
does not change significantly across that range. (Default is
Table).

ENR Spot Values
Opens a menu to enter a spot value
either for measurements at a single frequency or for
measurements across a range of frequencies that is narrow
enough such that the ENR value does not change
significantly across that range (Inactive with ENR Mode set
