When displayed the menus cover quite a lot of the screen real estate so I find that I am forever pressing the Menu Off button to see the full screen again. They make some of the low end oscilloscopes for Agilent see here for the proof and I can understand why that is so.

This is not intended as a criticism of the Rigol but a larger screen with a higher resolution would be much easier to work with.

The options selected by the menu system are endless.
The instrument itself is quite small, about the size of a small shoebox. Display and Triggering The stability of the trace is excellent. Because this is a digital oscilloscope it will display a dotted horizontal line illustrating the trigger level as you adjust it and this makes it easy ueb see exactly at what point of the waveform you are triggering on.
Geoff’s Projects – Rigol DSE Series Oscilloscopes
The Rigol DS series is a hi-tech digital oscilloscope with udb exceptional set of features at a price that a hobbyist can afford. The image on the right is a full sized example of a screen dump the purple trace is the maths function showing the difference between the two channels.
Options in the menu are selected by pressing one of the vertical row of soft buttons on the right of the screen. Computer Control You can plug the USB socket on the back of the oscilloscope into your computer and either take remote control of the instrument or download data and screen shots. Rather than repeat the specs and the operating details I will keep this discussion to the points not covered in the documentation. Triggering is solid and very precise.
Rigol is a Chinese electronics instrument manufacturer who has been around for only a few years. The Display The display is a 5. An issue that the early digital oscilloscopes seemed to have was a delay between turning a knob or pressing a button and the instrument responding. This is quite an achievement for an instrument with a lot of capabilities and a limited set of front panel controls.
Useability The DSE series is certainly easy to use, the knobs and buttons do what you would expect and you can quickly focus on the detail that you are looking for. The only issue is that when Rigol learns that this information is public knowledge they will almost certainly change their firmware to prevent this exploit this information became public in March The Fan While on the subject of annoyances I must mention the fan.
The pity is that the fan is really only needed on a very hot ds1000ee but it runs at full speed all the time. This is not as bad as it sounds as repeated pressing of the button will get me back to where I want to be but it could have been designed much better. I found the remote control just as difficult to use as other USB oscilloscopes but the ability to download data and, more particularly, screen shots is very useful.
With the ongoing march of technology hopefully we will find that 8 inch screens with full VGA resolution will become the standard in the future and that would be just about perfect.
Perhaps I have been spoilt by high resolution computer screens but I would have preferred something with more detail. I haven’t quite figured out the sequence yet sd1000e when I press a button to select a channel for adjustment I sometimes find that the menu has popped up or worse, the channel has disappeared altogether.
This causes another usability issue in that these same channel select buttons are also used to display the menu for the channel or cause the channel to be tuned off. Rigol mostly manages to do this trick by the extensive use of a menu system dd1000e pops up on the right hand side of the screen as do most digital scopes. All these numbers are for when one channel is active, when you use two channels they are halved. Rs1000e screen grabs below show the two functions in action.
Mostly the menus and the options are easy to understand but some selections invoke a second menu layer and that can get confusing. Because the screen shots recorded on the instrument were so small it is much better to use the Rigol software on your computer to get a screen shot with a useful resolution.

As it is, rather than figure out what channel is currently under control, I just push the button for the channel that I want and then adjust the knobs. There is a version of the DS series which includes a 16 channel logic analyser.
When displayed the menus cover quite a lot of the screen real estate so I find that I am forever pressing the Menu Off button to see the full screen again.
Theoretically you can see what channel is currently associated to the knobs by checking the icons on the bottom of the screen but it would have been much better if the appropriate channel select button was illuminated with a different colour.

Specifications The specifications for the DS series are included in the user manual which you can download from the Rigol website here. This video will show you what I mean. The options in this department are extensive to say the least – you can trigger on the normal rising and falling edge of a signal but also on various rise times, pulse widths, video characteristics and more.
