4 To make other measurements, press the [Meas] key and set the Source softkey to
Math: f(t).
You can make peak-to-peak, maximum, minimum, and average dB
measurements on the FFT waveform.
The following FFT spectrum was obtained by connecting a 4 V, 75 kHz square
wave to channel 1. Set the horizontal scale to 50 µs/div, vertical sensitivity to
1 V/div, Units/div to 20 dBV, Offset to -60.0 dBV, Center frequency to 250 kHz,
frequency Span to 500 kHz, and window to Hanning.
