Probe Safety A guard around the probe body provides a finger barrier for protection from electric shock. Figure 2.5 – Oscilloscope Probe Connect the probe to the oscilloscope and connect the ground terminal to ground before you take any measurements. SHOCK HAZARD To avoid electric shock when using the probe, keep fingers behind the guard on the probe body. To avoid electric shock while using the probe, do not touch metallic portions of the probe head while it is connected to a voltage source.
Probe Attenuation Probes are available with various attenuation factors which affect the vertical scale of the signal. The Probe Check function verifies that the Probe attenuation option matches the attenuation of the probe. You can push a vertical menu button (such as the CH 1 MENU button), and select the Probe option that matches the attenuation factor of your probe. NOTE: The default setting for the Probe option is 1X.
AUTO BUTTON PROBE COMP CH1 Figure 2.6 – Probe Compensation Setup 1. 2. 3. Set the Probe option attenuation in the channel menu to 10X. Do so by pressing CH1 button and selecting “Probe” from menu. Select 10X. Set the switch to 10X on the probe and connect the probe to channel 1 on the oscilloscope. If you use the probe hook-tip, ensure a proper connection by firmly inserting the tip onto the probe.

If the channel is set to DC coupling, you can quickly measure the DC component of the signal by simply noting its distance from the ground symbol. If the channel is set to AC coupling, the DC component of the signal is blocked allowing you to use greater sensitivity to display the AC component of the signal. Setting up Channels Each channel has its own separate Menu. The items are set up separately according to each channel. 1.
Figure 3.6 – DC Coupling • 2. Press “CH1”→“Coupling”→“GND”, Set to GROUND mode. This disconnects the input signal. Bandwidth Limiting Take CH1 for example: • Press “CH1”→“BW Limit”→ “On”, and bandwidth will be limited to 20 MHz. • Press “CH1”→“BW Limit”→ “Off”, and bandwidth limit will be disabled.
Figure 3.7 – Bandwidth Limit 3. Volts/Div Settings Vertical scale adjust have Coarse and Fine modes, Vertical sensitivity range of 2 mV/div – 10 V/div. Take CH1 for example: • Press “CH1”→“Volts/Div”→“Coarse”. It is the default setting of Volts/Div, and makes the vertical scaling in a 12-5-step sequence from 2 mV/div, 5 mV/div, and 10 mV/div to 10 V/div. • Press “CH1”→ Volts/Div”→ Fine”. This setting changes the vertical control to small steps between the coarse settings.

Table 3.31 – Acquire Function Menu Option Acquisition Sinx/x Mode Sa Rate Setting Description 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.
Disadvantage: This mode does not acquire rapid variations in the signal that may occur between samples. This can result in aliasing may cause narrow pulses to be missed. In these cases, you should use the Peak Detect mode to acquire data. Figure 3.30 – Acquire Menu Peak Detect: Peak Detect mode capture the maximum and minimum values of a signal Finds highest and lowest record points over many acquisitions.
Figure 3.31 – 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.
Figure 3.32 – Average Acquisition Equivalent Time Sampling: The equivalent time sampling mode can achieve up to 20 ps of horizontal resolution (equivalent to 50GSa/s). This mode is good for observing repetitive waveforms. Real Time Sampling: The scope has a maximum Real-time sampling rate of 1GSa/s. “RUN/STOP” Button: Press the RUN/STOP button when you want the oscilloscope to acquire waveforms continuously. Press the button again to stop the acquisition.
2. Continue to acquire data while waiting for the trigger condition to occur. 3. Detect the trigger condition. 4. Continue to acquire data until the waveform record is full. 5. Display the newly-acquired waveform. Time Base: The oscilloscope digitizes waveforms by acquiring the value of an input signal at discrete points. The time base allows you to control how often the values are digitized. To adjust the time base to a horizontal scale that suits your purpose, use the Time/div knob.
Set up function interpolation You can select Sinx interpolation or linear interpolation. Set up Sampling Mode Press the “Mode” option button to select “Real Time” or “Equ Time”. Set up Sampling Rate The sampling rate is based on the time division scaling on the screen. Adjust the sampling rate by turning the Time/div front panel knob. The sampling rate is shown under the “Sa Rate” display. 3.13 Display System The display function can be setup by pressing the “DISPLAY” button. Table 3.

6 Message Prompts and Troubleshooting 6.1 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 horizontal position knob. Volts/Div at limit! : Prompts you that the vertical voltage has already reached the Min 2mV/div or the Max 5V/div.
USB Flash Drive isn’t connected! : When the “Save To” option is set to “File” or the “Print Key” option is set to “Save Picture” in “Save/Recall” menu , press the “Save” option button or the “Time/div” knob before inserting 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. 6.2 Troubleshooting 1. 2. 3. 4. After the oscilloscope is powered on, the screen remains dark.
5. “edge” trigger mode. The video signal should use the “Video” Trigger mode. The signal would display steadily only when using matching trigger mode. 3. Attempt to change the “coupling” into “HF Reject” or “LF Reject” display, so that the High/low frequency noise will be filtered. When pressing “RUN/STOP” button, nothing displays. Check whether or not the trigger mode on the trigger interface is in “normal” or “single”, and then check the trigger level to see if it is over the waveform range.
7 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: The oscilloscope must have been operating continuously for 30 minutes within the specified operating temperature. You must perform the Do Self Cal operation, accessible through the Utility menu, if the operating temperature changes by more than 5° C.
Lower frequency limit (AC -3 dB) ≤10 Hz (at input BNC) DC Gain Accuracy 5 mV/div to 10 V/div in Fixed Gain Ranges: <±3.0% 2 mV/div Variable Gain Ranges: <±4.0% DC Measurement Accuracy: All Gain settings ≤ 100 mV/div DC Measurement Accuracy: All Gain settings > 100 mV/div Rise time Overshoot, Typical (using 500 ps pulse) Math operation FFT Bandwidth limited Horizontal System Real Time Sampling Rate Max.
