FM Demod
Displays the FM Demod menu used in the FM demodulation
mode.
Range
Used to switch the frequency range along the vertical axis.
Deviation
Displays the Deviation menu, deviation of an FM demodulated
signal, positive peak deviation, negative peak deviation, and rep-
etition frequency.
Peak Delta Y
Sets peak detection measurement conditions when a deviation is
measured.
Deviation OFF
Turns the deviation measurement function off.
Sensitivity
Displays the Sensitivity menu, differentiates a demodulated FM
signal with respect to time, and displays the differential value.
Sens Range
Magnifies the curve consisting of differential values in up to four
positions, each of which must use any number(s) from 1, 2 and 5.
Aperture %
Sets the section (%) along the horizontal axis to calculate a differ-
ential value. The entire range is defined as 100%.
Sensitivity OFF
Turns the differential value display off.
Linearity
Displays the Linearity menu, and then switches to Separate
Screen Mode. The reference line is displayed in the lower part of
the screen.
Auto Adj
Automatically calculates the reference line of a demodulated FM
signal using the least-square method.
Sample Points
Sets the number of points for the calculation using the least-
square method.
Offset Adj
Sets the offset value of the reference line.
Slope Adj
Sets the inclination of the reference line.
Linearity ON/OFF ON:
Displays the maximum and minimum errors between a
trace and the reference line.
OFF:
Turns off the error display between a trace and the ref-
erence line.
Screen A/B
Toggles the active screen between A and B.
Lin Setup Quit
Quits from the Linearity Setting screen.
