Acquiring Signals System Shown below is the “ACQUIRE” button for entering the menu for “Acquiring Signals”. Table 28- Acquiring Signals Function Menu Option Setting Introduction Acquisition Sampling Use for sampling and accurately display most of the waveform. Peak Detect Detect the noise and decrease the possibility of aliasing. Average Use to reduce random or uncorrelated noise in the signal display. Sinx/x Mode Sa Rate Averages (4, 16, 32, 64, Select number of averages.
• Sampling: In this acquisition mode, the oscilloscope samples the signal in evenly spaced intervals to construct the waveform. This mode accurately represents signals most of the time. Advantage: You can use this mode to reduce random noise. Disadvantage: This mode does not acquire rapid variations in the signal that may occur between samples. This can result in aliasing, which may cause narrow pulses to be missed. In these cases, you should use the Peak Detect mode to acquire data.
Advantage: In this way, the oscilloscope can acquire and display narrow pulses, which may have otherwise been missed in Sample mode. Disadvantage: Noise will appear to be higher in this mode. Figure 41 - Peak Detect • Average: The oscilloscope acquires several waveforms, averages them, and displays the resulting waveform. Advantage: You can use this mode to reduce random noise.

Chapter 4 Message Prompts and Troubleshooting Message Prompts • Trig level at limit! : Prompts you that the trigger Level is at a limit when you turn the Trig level knob. • Horizon position at limit! : Prompts you that the horizontal position is at a limit when you turn the horizon position knob. • Volts/Div at limit! : Prompts you that the vertical voltage have already touched the Min 2MV/div or the Max 5V/div.
• No signal! : The system would display this information when the signal could not match the auto set condition. (Using in the auto set) • Adjust at limit! : You could adjust the pulse width by the universal knob till the pulse width has reached min 20.0 ns or max 10.0 s. • Location Empty! : If you have no stored waveforms or setups on some location, the screen will display this information when you press the “Recall” button on this location.
“Save/Recall” menu , Press the “Save” option button or the “time/div” knob before inverting the USB Flash Drive to the USB Host port or this will appear on the screen. • Record Wave Success! : This message will appear when you finish recording waveforms. Troubleshooting 1. After the oscilloscope is powered on, the screen remains dark. Please do the following: 1. Check the power cable’s connection. 2. Ensure the power switch is turned on. 3. After the inspections above, restart the oscilloscope. 4.
3. Check the probe whether it’s connected with the device under test (DUT) or not. 4. Check the tested DUT to see if it produces the signal or not. 5. 3. Try to probe the DUT for signal again. The value of the tested voltage is 10 times higher/lower than the real one , please do the following: Check the attenuation quotient whether it matches the probe attenuation proportion or not. 4. Display the wave, but not steady , please do as following steps: 1.
Check the trigger mode on the trigger interface whether or not it’s in “normal” or “single”, and check the trigger level whether or not it is over the wave range. If yes, please put the trigger level to the middle position or set the trigger mode to the “Auto” position. Another way is to choose the “Auto” button to set up automatically. 6. After the Acquisition is set to Averages or Display Persistence time is set too long, the waveform refreshes slowly. It is normal in these settings. 7.
Chapter 5 Specifications • All specifications apply to measurements with a 10X probe To verify that the oscilloscope meets specifications, the oscilloscope must first meet the following conditions: o The oscilloscope must have been operating continuously for thirty minutes within the specified operating temperature. o You must perform the Do Self Cal operation, accessible through the Utility menu, if the operating temperature changes by more than 5° C.
