www.GlobalTestSupply.com

DS70000 User Guide

the waveform would enlarge or reduce. The scale information of the channel status label at the bottom of the screen would change accordingly.

The adjustable range of the vertical scale is related to the currently set probe ratio and input impedance. By default, the probe ratio is 1X and the input impedance is 1 MΩ. In this case, the adjustable range of the vertical scale is from 1 mV/div to 10 V/ div.

Caution

When the vertical scale is 1 mV/div and 2 mV/div, the 250M bandwidth limit will be

enabled automatically.

When CH1 is turned on, you can adjust the vertical scale with the following methods:

• Rotate the knob that corresponds to CH1 to adjust the vertical scale (clockwise

to reduce the scale and counterclockwise to increase).

• Enable the touch screen function, and then adjust the vertical scale with the

5.4 Channel Coupling

The undesired signals can be filtered out by setting the coupling mode. For example, the signal under test is a square waveform with DC offset.

Click or tap the channel status label at the bottom of the screen. Then the Vertical menu is displayed. Click or tap the drop-down button of the Coupling menu to select the coupling mode.

• When the coupling mode is "DC": the DC and AC components of the signal

under test can both pass the channel.

• When the coupling mode is "AC": the DC components of the signal under test

are blocked.

• When the coupling mode is "GND": the DC and AC components of the signal

under test are blocked.

After selecting the coupling mode, the currently selected coupling mode is displayed in the channel status label at the bottom of the screen, as shown in the figure below.

Tip

When the input impedance is set to "50 Ω", the channel coupling is set to DC coupling by

force, and the Coupling menu is grayed out and cannot be modified.

5.5 BW Limit

This oscilloscope 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.

• If 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.

The acquisition mode is used to control how to generate waveform points from the sample points. In the Horizontal system menu, click or tap the desired acquisition mode for the Acquisition menu. The available choices include Normal, Average, Peak, High Res. By default, the acquisition mode is Normal. The acquisition mode will be displayed in the acquisition label at the top of the screen.

Normal

In this mode, the oscilloscope samples the signal at a specified fixed time interval to rebuild the waveform. For most of the waveforms, using this mode can produce the optimal display effects.

Find Quality Products Online at: sales@GlobalTestSupply.com

www.GlobalTestSupply.com

DS70000 User Guide

Average

In this mode, the oscilloscope averages the waveforms from multiple samples to reduce the random noise of the input signal and improve the vertical resolution. Greater number of averages can lower the noise and increase the vertical resolution; while at the same time, it will slow the response of the displayed waveform to the waveform changes.

When you select "Average" mode, click or tap the input field for the

item to set it by using the pop-up numeric keypad. Its range is from 2 to 65534. Its default value is 8.

Tip

The number of averages must be the Nth power of 2. When it is not in N power-of-2

increments, a prompt message "Truncation average error" is displayed. At this time, a value

that is smaller than the one you input and the closest to N power-of-2 increments will be input

automatically. For example, if you input 9 with the numeric keypad, the average count will be

input 8 automatically.

Peak

In this mode, the oscilloscope acquires the maximum and minimum values of the signal within the sample interval to get the envelope of the signal or the narrow pulse that might be lost. In this mode, signal aliasing can be prevented, but the noise displayed would be larger.

In this mode, the oscilloscope can display all the pulses whose pulse widths are at least the same as the sample period.

High Resolution

This mode uses a kind of ultra-sample technique to average the neighboring points of the sample waveform to reduce the random noise on the input signal and generate much smoother waveforms on the screen. This is generally used when the sample rate of the digital converter is higher than the storage rate of the acquisition memory.

When you select "High Res" mode, click or tap the drop-down button of

bits to select

9, 10, 12, 14, or 16. Its default value is 9.

Tip

• The averaging modes of the "Average" and "High Res" are different. The former uses

"Multi-sample Average" and the latter uses "Single Sample Average".

• In "High Res" mode, the oscilloscope improves the measurement accuracy at the cost of

bandwidth. Each time the sampling rate changes, a window displaying the current

bandwidth appears in the sample rate menu.

7.3 Sample Rate

Sampling is the process of converting the analog signal into the digital signal at a specified time interval and then restoring them in sequence. The sample rate is the reciprocal of the time interval.

STOP/RUN

In the Horizontal system menu, "SampleRate" shows the current sample rate. The current sample rate is displayed in the acquisition label at the top of the screen, as shown in the figure below.

The sample rate of the analog channel is related to the current channel mode. The maximum real-time sample rate in the single-channel mode is 20 GSa/s, and the maximum real-time sample rate in the half-channel mode and full-channel mode is 10 GSa/s.

• Single-channel mode: CH1 and CH2 are considered as a group; CH3 and CH4

are considered as another group. If one of the two channels in each group is enabled, it is called single-channel mode.

• Half-channel mode: CH1 and CH2 are considered as a group; CH3 and CH4 are

considered as another group. If two channels in either one of the groups are enabled, it is called half-channel mode.

• Full-channel mode: CH1, CH2, CH3, and CH4 are all enabled.

The impact of low sample rate on the waveform:

• Waveform Distortion: when the sample rate is too low, some waveform details

are lost, and the sample waveform displayed is rather different from the actual waveform of the signal.

Find Quality Products Online at: sales@GlobalTestSupply.com

www.GlobalTestSupply.com

DS70000 User Guide

• Waveform Aliasing: when the sample rate is twice lower than the actual signal

frequency (Nyquist Frequency), the frequency of the waveform rebuilt from the sample data is smaller than the actual signal frequency.

• Waveform Leakage: when the sample rate is too low, the waveform rebuilt from

the sample data does not reflect all the actual signal information.

7.4 Memory Depth

At a slower sweep speed, the sample rate is reduced, and a dedicated display algorithm can be used to minimize the possibility of aliasing.

In the Horizontal system menu, the user can select the on or off tab for the Anti- aliasing menu to enable or disable the anti-aliasing function.

This function should be enabled when the horizontal time base has a large deviation from the period of the signal under test (e.g. when the horizontal time base is greater than five-fold the period of the signal under test).

7.6 Horizontal Expansion

Horizontal expansion indicates the reference position that the screen waveform is referenced to when it is horizontally expanded or compressed in adjusting the horizontal time base. In the Horizontal system menu, click or tap the drop-down button of Expand to select the horizontal reference baseline. The available choices include Center, Left, Right, Trigger, and User. The default is "Center".

8 To Trigger the Oscilloscope

As for trigger, you set certain trigger condition according to the requirement and when a waveform in the waveform stream meets this condition, the oscilloscope captures this waveform as well as the neighboring part, and displays them on the screen. For the digital oscilloscope, it samples waveform continuously no matter whether it is stably triggered, but only stable trigger can be stably displayed. The trigger module ensures that every time base sweep or acquisition starts from the user-defined trigger condition, namely every sweep is synchronous with the acquisition and the waveforms acquired is overlapped so as to display the stable waveforms.

Trigger settings should be based on the features of the input signal. To quickly capture the desired waveform, you need to understand the signal under test. This oscilloscope provides abundant trigger types that help you focus on the desired waveform details.

small screen, the oscilloscope will stop after finishing a single acquisition (you can pan and zoom the currently displayed waveform).

DS70000 provides Auto, Normal, and Single trigger modes, and the default is Auto.

Click or tap the trigger information label at the top of the screen or the "Trigger" icon on the small screen to open the "Trigger" menu. Click or tap the sub-items for the Sweep menu to quickly switch the current trigger mode. The trigger mode is displayed in the trigger information label at the top of the screen: A (Auto), N (Normal), and S (Single).

• Auto: In this trigger mode, if the specified trigger conditions are not found, triggers are forced and acquisitions are made so as to display the waveforms. This trigger mode should be used when the signal level is unknown or the DC should be displayed as well as when forcible trigger is not necessary as the trigger condition always occurs.

• Normal: In this trigger mode, triggers and acquisitions only occur when the specified trigger conditions are found. This trigger mode should be used when the signal is with low repetition rate or only the event specified by the trigger setting needs to be sampled as well as when auto trigger should be prevented to acquire stable display.

• Single: In this trigger mode, the oscilloscope performs a single trigger and acquisition when the specified trigger conditions are found, and then stops. This trigger mode should be used when you need to perform a single acquisition of the specified event and analyze the acquisition result (you can pan and zoom the currently displayed waveform, and the subsequent waveform data will not overwrite the current waveform). After a single trigger mode is initiated, the operating status of the oscilloscope is in "STOP" state.

Normal and Single trigger modes, pressing Force in the trigger menu or the

In "Force" icon on the small screen can generate a trigger signal forcibly.

8.4 Trigger Coupling

Trigger coupling decides which kind of components will be transmitted to the trigger module. Please distinguish it from " when the trigger type is Edge and the trigger source is an analog channel.

• DC: allows DC and AC components to pass the trigger path.

• AC: blocks the DC components and attenuates the signals.

• LFR: blocks the DC components and rejects the low-frequency components.

• HFR: rejects the high frequency components.

Tip

When "AC" or "LFR" is selected for the coupling mode, no trigger level lines and trigger icons

are displayed. When you adjust the trigger level, you can only see the changes of the trigger

level values in the trigger information label at the top of the screen.

8.5 Trigger Holdoff

Trigger holdoff can be used to stably trigger on complex repetitive waveforms that have multiple edges (or other events) between waveform repetitions (such as pulse series). Holdoff time indicates the time that the oscilloscope waits for re-arming the trigger module after generating a correct trigger. The oscilloscope will not trigger even if the trigger condition is met during the holdoff time and will only re-arm the trigger module after the holdoff time expires.

For example, to stably trigger the repetitive pulse series as shown in the figure below, the holdoff time should be set to a value that is greater than t1 and smaller than t2.

Figure 8.2 Trigger Holdoff

default, the holdoff time is 8 ns) with the pop-up numeric keypad. The adjustable range of the holdoff time is from 8 ns to 10 s.

8.6 Noise Rejection

Noise rejection can reject the high frequency noise in the signal and reduce the possibility of miss-trigger of the oscilloscope.

Click or tap the trigger information label at the top of the screen or the "Trigger" icon on the small screen to open the "Trigger" menu. Click or tap the ON/OFF tab for the

Noise Reject menu to enable or disable the noise rejection function.

Tip

This function is only valid when the trigger source is an analog channel or EXT.
