I-Phi curve
Select the I-Phi curve to be shown on the graphics area. Curve is
shown only if a I-Phi measurement has been performed during the
session. See “I-Phi measurement” on page 46.
Modulation
Select the overview of relative modulation depths. See “I-Phi mea-
surement” on page 46.
Modulation (abs)
Select the overview of absolute modulation depths. See “I-Phi mea-
surement” on page 46.
I-V curve
Show the last measured I-V curve. See “Measuring and using cur-
rent-voltage characteristics” on page 54.
Noise
Select the white noise level to be shown on the graphics area. See
“Measuring the sensor noise level” on page 11.
Noise histogram
Select the white noise level histogram to be shown. See “Measuring
the sensor noise level” on page 11.
FFT
Select the spectrum of the signal on the selected channel, or a over-
view of noises on all of the channels when channel zero is selected.
See “FFT measurement” on page 49.
Signal
Select viewing of signal samples. See “Signal” on page 50.
Gate curve
Select viewing of noise versus gate setting curve. See “Measuring
gate curves” on page 55.
