Oscilloscope Reference Select the bandwidth
Select the bandwidth
From the Vertical menu, select Vertical Setup.
Overview
Use the following controls (similar to the example shown below) to set the bandwidth and filter unwanted
high-frequ
ency noise from the waveform. You can also use the Bandwidth Enhancement Controls
(see
page 494) to normalize the bandwidths between selected channels.
To use
Click the appropriate option buttons and use the drop-down list box to specify the bandwidth you want to
acquire. The available selections and controls will vary depending on the instrument model and probe you
are using.
Behavior
Ban
dwidth refers to the range of frequencies the instrument can acquire and display accurately with less
than 3 dB attenuation. Each input channel has its own bandwidth selection.
To
take accurate measurements, the input frequency should be much less than the rated bandwidth of the
instrument. A good rule to follow is to ensure the bandwidth of the instrument system is three to five times
the bandwidth of the signal that you want to measure.
