To Enable the Channel

DS1000Z provides 4 analog input channels (CH1-CH4) and each channel can be controlled independently. As the vertical system setting methods of the 2 channels are completely the same, this chapter takes CH1 as an example to introduce the setting method of the vertical system.

Connect a signal to the channel connector of any channel (for example, CH1) and then press CH1 in the vertical control area (VERTICAL) at the front panel to enable CH1.

Screen:

The channel setting menu is display ed at the ri ght side of the screen an d the channel label at the bottom of the screen (as shown in the figure below) is highlighted. The information displayed in the channel label is related to the current channel setting.

After the channel is turned on, modify the pa r ameters such as the v ertical scale, the horizontal time base and the trig ger mo de according to the input signa l to make the waveform display easy to observe and measure.

Channel Coupling

Set the coupling mode to filter out the undesired signals. For example, the signal under test is a square waveform with DC offset.  When the coupling mode is “DC”: the DC and AC comp onents of the si gnal under

test can both pass the channel.

 When the coupling mode is “AC”: the DC components of the signal under test

are blo cked.

 When the coupling mode is “GND”: the DC and AC components of the signal

under test are both blocked.

Press CH1  Coupling and use to select the desired coupling mode (the default is DC). The current coupling mode is displayed in the channel label at the bottom of the screen. You can also press Coupling continuously to switch the coupling mode.

Bandwidth Limit

Set the bandwidth limit to reduce display noise. For example, the signal under t est is a pulse with high frequency oscillation.  When bandwidth limit is disabled, the high frequency components of the signal

under test can pass the channel.

 Enable bandwidth limit and limit the bandwidth to 20 MHz, the high frequ ency

components that exceed 20 MHz are attenuated.

Press CH1  BW Limit and use to enable or disable bandwidth limit (the default is OFF). When ban dwidth limit (20 MHz ) is e nabled, the char acter “B” will be displayed in the channel label at the bottom of the screen. You can also press BW Limit continuously to switch between on and off of the bandwidth limit.

Acquisition Mode

The acquisition mode is used to control how to generate waveform points from sample points.

Press Acquire  Mode in the function menu at the front panel and use to select the desired acquisition mode (the default is normal), then press down the knob to select this mode. You can also press Mode continuously to switch the acquisition mode.

Normal

In this mode, the oscilloscope sam ples the signal at equal time inte rval to re build the waveform. For most of the waveforms, the best display effect can be obtained using this mode.

Average

In this mode, the oscilloscope averages the waveforms from multiple samples to reduce the rand om noise of the input signal and im p ro v e the vertical resolution. The greater the number of averages is, the lower the no i se will be and the higher the vertic al resolution will be but the slower the response of the displayed waveform to the waveform changes will be.

The available ran ge of the number of ave rages is from 2 to 8192 a nd the def ault is 2. When “Average” mode is selected, press Averages and use to set the desired number of averages as the power function of 2.

Peak Detect

In this mode, the oscilloscope acquires the maximum and minimum values of the signal within the sample in terval to get the envel ope of the signal or the narrow pulse of the signal that might be lost. In this mode, signal confusi on can be prevente d but the noise displayed would be larger.

In this mode, the oscilloscope can display all the pulses with pulse widths at least as wide as the sample period.

High Resolution

This mode uses a kind of ultra-sample technique to average the neighboring points of the sample w aveform to reduce the random n oise on the input signal a nd generate much smoother waveforms on the screen. This is generally used when the sample rate of the digital converter is hi gher than the st orage r ate of the a cquisition memory.

Note: “Average” and “High Res” modes use diff e rent av er agin g met hods . The former uses “multiple sample average” and the latter uses “signle sample average”.

Memory Depth

Memory depth refers to the number of wavef orm points that the oscilloscope c a n store in a single trigger sample and it reflects the storage ability of the sample memory. DS1000Z provides up to 24 Mpts memory depth (option) and 12 Mpts standard memory depth.

The relation of memory depth, sam ple rate a nd wa ve form len gth fulfills the equation below:

Memory depth = sample rate (Sa/s) × waveform length (s/div × div)

Thus, in the same time base, the higher memory depth can ensure a higher sample rate.

Press Acquire  Mem Dept h, use to switch to the desired memory depth (the default is auto) and then press down the knob to select the option. You can also press Mem Depth continuously to switch the memory depth.

When a single channel is enabled, the memory depths available include Auto, 12kPoints, 120kPoints, 1200kPoints, 12MPoints. In “Auto” mode, the oscilloscope selects the memory depth automatically according to the current sample rate.

When two channels are enabled, the memory depths av ailable include Auto , 6kPoints, 60kPoints, 600kPoints, 6MPoints. In “Auto” mode, the oscilloscope selects the memory depth automatically according to the current sample rate.

Chapter 5 To Trigger the Oscilloscope

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 nei ghbourin g pa rt a nd displa ys t hem on the sc reen. For digital oscilloscope, it displays waveform continuously no matter whether it is stably triggered, bu t only stable trigger can ensure stable display. The trigger circuit ensures that every time base sweep or acquisition starts from the input signal and the user-defined trigger condition, namely every sweep is synchronous to the acquisition and the waveforms acquired overlap to display stable waveform.

Trigger setting sho uld be based on t he features of the input signal, th us yo u ne ed to have some knowledge of the signal under test to quickly capture the desired waveform. This os cilloscope provides abundant adv anced trigger f unctions which can help you to focus on t he desired waveform details.

Trigger Mode

Trigger mode affects the way in which the oscilloscope searches for the trigger. Th e following is the s chematic diagra m of the a cquisition memory. As shown in the figure below, the position of the trigger event is determined by the reference time point and the delay setting. Note that the acquisition memory of the oscilloscope is a cyclic buffer and the new data would overwrite the old data until the acquisition finishes.

Pre-trigger Buffer Post-trigger Buffer

Acquisition memory

Pre-trigger/Delayed trigger:

Acquire data before/after the trigger event. The trigger position is usually at the horizontal center of the screen. In full-screen display, six-grid pre-trigger and delayed trigger information are displayed respectively. You can adjust the horizontal position of the waveform through HORIZONTAL information and delayed trigger information, through which the signal information before/after the trigger (such as capture the glitch generated by the circuit and analyze the pre-trigger data to find out the reasons for glitch) can be obtained.

Press MODE in the trigger control area (TRIGGER) at the front panel or press MENU  Sweep to select the desired trigger mode. The corresponding stat us light of the mode currently selected turns on.

Auto:

No matter whether the trigger condition is met, there is always waveform display. A horizontal line is displayed when no signal is input. In this mode, the oscilloscope operates by first filling the pre-trigger buffe r. It starts searching for a trigger after the pre-trigger buffer is filled and continues to flow dat a through this buffer while it searches for the trigger. While searching for the trigger, the oscilloscope overflows the pre-trigger buff er and the first data put into the buffer

is first pushed out (First Input First Out, FIFO). When a trigger is found, the pre-trigger buffer would contain the data acquired just before the trigger. If no trigger is found, the oscilloscope will t rigger forcef ully. If forceful tri gger is inv alid, the oscilloscope still displays w a vef orm but the w av ef orm is not sta ble; if forceful trigger is valid, the oscilloscope displays stable wave fo rm. This trigger mode is applicable to low-repetitive-rate signals and unknown signal levels. To display DC signa ls, you must use auto trigger mode. Note: when the horizontal time base is set to 50 ms/div or greater, this tri gge r mode allows the absence of trigger signal.

Normal:

Display waveform when the trigger condition is met; otherwise, the oscilloscope holds the original waveform and waits for the next trigger. In this mode, the oscilloscope fills the pre-trigger buffer first and then search for a trigger while at the same time continues filling data. While searching for the trigger, the oscilloscope overflows the pre-trigger buff er and the first data put into the buffer is first pushed out (FIFO). When a trigger is found, the oscilloscope will fill the post-trigger buffer and display the a cquisitio n mem o ry. Use normal trigger mode for low-repetitive-rate signals or when auto trigger is not required. Note: in this mode, pressing FORCE can generat e a trigger signal forcefully.

Single:

When this mode is selected, the backlight of SINGLE turns on. The oscilloscope waits for a trigger and displays the waveform when the trigger condition is met and then stops. Note: in this mode, pressing FORCE can generate a trigg er signal forcefully.
