Can you disable the AUTOSET button on the DS4 and DS6 series?
There is an autoset disable remote command that can remove the feature from DS1000E/D scopes as well as many of our other scopes popular in educational environments. This is primarily done for student lab and educational purposes. Contact RIGOL if you need assistance doing this to your scope. We don't publicly post the information so that it can not easily be reenabled.
Can you set up any RIGOL scopes to stop triggering after a specific averaging number?
The average acquisition mode for the DS1000E/D, DS1000CA, DS1000B, DS4000, and DS6000 scopes are identical in function. They collect a boxcar average of the last n (usually a power of 2) acquisitions on a rolling basis.
On the DS1000Z, DS2000/A, DS4000, and DS6000 scopes users can enable record mode to capture a specific amount of triggers into a set of frames, but to average all that data together it would have to be done externally.
To save maximum data to an external USB stick, follow these steps:
Configure the scope to collect the data of interest. Single trigger mode will allow you to "freeze" the data. Alternately, you can use the Run/Stop button to stop triggering and "freeze" the data.
Insert a compatible USB drive into front panel.
Press Storage key in the menu area of the front panel.
Select CSV under the Storage menu label on the display
Select Maximum under Data Depth menu label on the display
Select External to save to the external USB drive
Select New File and enter a new file name
The DS1000E/D instruments have the ability to be locked from the front panel. If they are in a locked state, red letters LOCK will appear in the upper right-hand corner of the display as below:
To unlock the display, follow these instructions:
1. Press the grey/blue key just to the right of the displayed LOCK text.
2. A prompt will appear. The default unlock code for the DS1000 series scopes is “ 111111 “.
3. After you have selected the password, press the bottom most grey/blue button. This will enter the password. The LOCK label will disappear.

What is the longest time duration waveform that a DS1000E/D series scope can acquire?
The longest time division is 50s/division. Therefore, the scope will acquire 10 minutes of data (50s/division * 12 divisions = 600s / (60s/min) = 10 min
The DS1000E/D series of oscilloscopes can capture and save waveform data as a WFM file. These files are binary representations of the collected data that can then be saved to a USB memory device and transferred to a Rigol DG series of Arbitrary waveform generators for playback and manipulation.
For a single channel acquisition, the saved WFM file type is comprised of 16k (16,384) data points centered around the midpoint of the scope display. Approximately 8k points before and 8k after.
When this WFM is loaded into the DG1022, the instrument will sample 4096 data points from the midpoint of the original 16k points of data.
So, each WFM captured on a DS1000E/D series scope that is replayed on a DG1022 consists of 2043 points before and 2043 points after the central part of the scope display.
In a practical implementation, this represents an additional 25% window of data that lies just to the right and 25% just to the left side of the displayed data.
Figure 1 represents an example. The pink box surrounds the displayed data set. The red box surrounds the displayed data as well as an additional 25% on either side of the displayed data. The red box surrounds the data that would be replayed by the DG1022.
Figure 1: Composite of real displayed data (pink box)n and the additonal captured data replayed by DG1022 (red).
To replay the arbitrary waveform at the same rate as the originally acquired signal, take 4096/Sample Rate to calculate the playback period. Then set the DG1022 arbitrary waveform playback period to this value.
The Sample Rate parameter for the DS1000E/D scopes can be found by pressing the Menu key in the Horizontal control area of the front panel.
For example, if you acquired a waveform using a horizontal range with a sample rate of 100MSamp/s, the playback period would be 4096/(100E6 Samples/Sec) = 40.96us
This example and it's corresponding EXE use VISA to communication with a Rigol DS1000E/D scope.
The example allows the user to configure the oscilloscope for different data collection sizes (Normal or Long). It then graphs the data.
You can download the example EXE here.
The DS1000E/D series of oscilloscopes from Rigol can download captured waveforms containing up to 1 million data points. Here are the commands and proper order for remote retrieval of the data over USB.
There are some conventions that need to be established:
1. Set memory depth:
Where <depth> can be LONG or NORM. For actual data depth, see Table 1 below.
2. Set the waveform points mode:
Where can be NORM, RAW, or MAX See table 1 below for data points returned in each mode.
3. Set Scope operation mode: :RUN or :STOP
4. Return data: :WAVeform:DATA? <source>
Where can be CHAN1, CHAN2, DIG (For D series only), MATH, or FFT
NOTE: The first time you run the “:WAVE:DATA?” command, you will return 600 points. To return more points, you will need to operate the scope in “:STOP” mode.
Here is the command set to return 1M points from channel 1
1NOTE: It may be helpful to insert a wait or sleep between commands to prevent communications errors. Typically, a 10-20ms is sufficient.
1. Send “:ACQ:MEMDEPTH LONG”
2. Send “:WAVeform:POINts:MODE MAX”
3. Send “:RUN” to acquire waveform of interest.
Once you have capture your waveform, continue to step 4.
4. OPTION: It may be useful to use the Single Trigger mode by sending “:TRIG:SING:MODE” instead of then sending STOP. Otherwise:
5. Send ”:STOP”
6. Send ”:WAV:DATA? CHAN1”
7. Retrieve data from step 4.
8. You may need to do a number of receives to get all the data from the buffe
Typical data transfer speeds for 1 million points is between 5 and 6 seconds.
