12.2 Job Menu
This menu contains buttons that define the operation that should be per-
formed. The job is not executed immediately. These buttons only select
which job will be run when the “start button” is pressed. For more detailed
descriptions of the jobs see Chapter 8 and Chapter 9.
I/Phi
Select measurement of flux to current characteristics.
Noise
Select white noise measurement. This gives less information, but is
faster than a measurement of noise spectrum. It also provides the
level of line frequency disturbance and the dc-levels of all the chan-
nels.
FFT
Select FFT measurement that gives the spectrum of the signals. This
gives information about the noise as a function of frequency, but it is
slower than a measurement of white noise only.
Signal
Measure signal samples.
