Sensitivity Measurement
The sensitivity measurement calculates the ∆F/∆T of trace data, and displays it. ∆T is
determined by Aperture as shown in the formula below:
∆T = Sweep time × Aperture [%]
The unit of the vertical axis is [Hz/ms/] for a frequency range of 1 MHz/ or more, and
is [Hz/s/] for a frequency range of 500 kHz/ or less. The value of the vertical axis (sen-
sitivity range) is optimized according to the frequency range and sweep time used.
