You
may use cursors to take two measurements on the FFT spectrum: amplitude (in dB) and
frequency (in Hz). Amplitude is referenced to 0db that equals 1VRMS here.
You
may use cursors
to measure at any zoom factor.
Push the CURSOR button, choose the Source option and then select Math. Press the Type option
button to select between Amplitude and Frequency. Click the SELECT CURSOR option to choose
a cursor. Then use the V0 knobs to move Cursor S and Cursor E. Use the horizontal cursor to
measure the amplitude and the vertical cursor to measure the frequency. Now the display at the
DELTA
menu is just the measured value, and the values at Cursor S and Cursor E.
Delta is the absolute value of Cursor S minus Cursor E.
