Making Measurements

•Scale — lets you set your own vertical scale factors for FFT expressed in dB/div (decibels/division). Press the Scale softkey, then turn the Entry knob to rescale your math function.

•Offset — lets you set your own offset for the FFT. The offset value is in dB and is represented by the center horizontal grid line of the display. Press the Offset softkey, then turn the Entry knob to change the offset of your math function.

Scale and offset considerations

If you do not manually change the FFT scale or offset settings, when you turn the horizontal sweep speed knob, the span and center frequency settings will automatically change to allow optimum viewing of the full spectrum. If you do manually set scale or offset, turning the sweep speed knob will not change the span or center frequency settings, allowing you see better detail around a specific frequency. Pressing the FFT Preset softkey will automatically rescale the waveform and span and center will again automatically track the horizontal sweep speed setting.

3To make cursors measurements, press the Cursors key and set the Source softkey to Math.

Use the X1 and X2 cursors to measure frequency values and difference between two frequency values (∆ X). Use the Y1

and Y2 cursors to measure amplitude in dB and difference in amplitude (∆ Y).

4To make other measurements, press the Quick Meas key and set the Source softkey to Math.

You can make peak-to-peak, maximum, minimum, and average dB measurements on the FFT waveform. You can also find the frequency value at the first occurrence of the waveform maximum by using the X at Max measurement.

The following FFT spectrum was obtained by connecting the front panel Probe Comp signal (~1.2 kHz) to channel 1. Set sweep speed to 5 ms/div, vertical sensitivity to 500 mV/div, Units/div to 10 dBV, Offset to -34.0 dBV, Center frequency to 5.00 kHz, frequency Span to 10.0 kHz, and window to Hanning.
