Bandwidth Limit 
 
MSO/DS7000 series supports the bandwidth limit function. Setting the bandwidth 
limit can reduce the noises in the displayed waveforms. For example, the signal 
under test is a pulse with high frequency oscillation. 
⚫  When the bandwidth limit is disabled, the high frequency components of the 
signal under test can pass the channel. 
⚫  When you enable the bandwidth limit and limit it to 20 MHz or 250 MHz, the high 
frequency components found in the signal under test that are greater than 20 
MHz or 250 MHz are attenuated. 
 
Press 1 to open the setting menu of CH1.Then, press BW Limit continuously or 
rotate the multifunction knob    to select the desired bandwidth limit. Press down 
the knob to select it. By default, it is OFF. When the bandwidth limit is enabled, the 
character "B" will be displayed in the channel status label at the bottom of the screen, 
as shown in the figure below. You can also enable the touch screen, and then tap the 
CH1 setting menu to select the desired bandwidth limit. 
 
 
The bandwidth limit that you select is based on the bandwidth of your oscilloscope 
model, as shown in Table 2-1. 
 
Table 2-1 Bandwidth Limit 
 
Note: Bandwidth limit can not only reduce the noise, but also can attenuate or 
eliminate the high frequency components of the signal. 
 
 
Probe Ratio 
 
MSO/DS7000 series allows you to set the probe attenuation manually. To obtain the 
correct measurement results, you must set the probe ratio properly. By default, the 
probe ratio is 1X. 
 
Press 1 to open the setting menu of CH1.Then, press Attenuation continuously or 
rotate the multifunction knob    to select the desired probe ratio. You can also 
enable the touch screen, and then touch the CH1 setting menu to select the desired
