ELT-400 5 Operation and use
5-15
Example
Sinusoidal signal in range 10–500 Hz, measured in Exposure STD mode
• Analog output voltages on channels X, Y and Z are phase-shifted
relative to the measured field strength by approx. 90° (due to the
differentiating transfer function in Exposure STD mode).
• The output signal is the derivative vs. time of the field strength.
