Math Key -> Operator -> FFT -> Window Softkey help information

Applies a window to the FFT input signal.

* Rectangular - Best frequency resolution but worst amplitude accuracy. Excellent to measure a transient

signal where the signal levels before and after the event are nearly the same.

* Hanning - Good frequency resolution, low spectral leakage, and fair amplitude accuracy. Useful for measuring

transients or bursts where the signal levels are significantly different before and after the event.

* Hamming - Better frequency resolution, moderate spectral leakage, and fair amplitude accuracy. Suitable to

look at sine, periodic, and narrow bank spectral noise.

* Blackman - Worst frequency resolution, low spectral leakage, and good amplitude accuracy. Mainly to measure

single frequency signal to detect higher-order harmonics.

* Bartlett - Similar to Hanning but with higher and wider secondary lobes. Good to measure the narrowband signals

with strong noise interference.

* Flattop - With highest amplitude flatness. Used to make accurate amplitude measurements of frequency peak.

Math Key -> Operator -> FFT -> FFT Only Softkey help information

Selects to display both the source waveform and the FFT waveform together, or to display the FFT waveform

only.

Math Key -> Operator -> FFT -> AutoScale Softkey help information

Adjusts the FFT frequency Center and Span to the optimal values in order to display the entire available

spectrum.

V0 Knob help information

The V0 knob is a multifunction knob, used to select items from menus and input values. Its function changes

when a different menu is displayed.

Its indicator lights up when this knob is active and can be used to select a value.

Turning the knob will move the selection cursor up or down, and push the knob will select the item.

On the pop-up keyboard, turn the knob to select the desired letter or number, and then push the knob to

select the value to add to the input.

Vertical Position Knob help information

Turn the vertical position knob to move the waveforms up or down on the display.

Reset the reference to the vertical center of the screen by pushing the knob.

There is one vertical position knob for each channel.

Vertical Scale Knob help information

Rotate the vertical scale knob to set the volts/div of a waveform. The waveform display will contract or expand

relative to the ground reference level. Press this knob to toggle between fine (in smaller increments) and coarse

(in 1-2-5 step sequence) adjustment.

There is one vertical scale knob for each channel.

WisdomAugust

Horizontal Position Knob help information

Rotate the horizontal position knob to move the trigger point (indicated by the blue icon at the top of the display)

left and right on the display, adjusting the horizontal offset.

Push the horizontal position knob to set the trigger point to the center of the display (time reference point).

Horizontal Scale Knob help information

Turn the horizontal scale knob to adjust the sweep speed. This modifies the time base (sec/div) on the display.

When adjusted after the waveform has been acquired and the scope is stopped, this has the effect of zoom in/out

the waveform horizontally.

Push the horizontal scale knob to turn on or off the split-screen zoom display. To change the width of the zoom

window by rotating this knob.
