In this article I share a few tips I've learned about using the Rigol DS1052E oscilloscope.

Push the knobs
The knobs all have convenient actions if you push them: pushing Vertical Position or Horizontal Position centers the trace vertically or horizontally. Pushing Tigger Level sets it to zero. Pushing Scale sets it to fine adjust mode.Long Memory
If you don't use Long Memory, you're wasting most of the capacity of the oscilloscope. Long Memory stores 64 times as much data, so you can really zoom in on the waveform. To enable Long Memory, push the Acquire menu button, then select MemDepth to set Long Mem. There's additional documentation here.

Use zoom
Once you've recorded a waveform, you can pan across it using the horizontal position knob - the waveform window indicator at the very top of the screen shows where you are. In mid-range settings, however, the pan range is fairly limited (about a factor of 5) compared to how deep you can zoom with the horizontal scale knob (about a factor of 1000 with Long Memory). Note: zoom works best with Single triggering; if you use Auto or Norm triggering and hit Run/Stop, sometimes the detailed data isn't in memory and zoom doesn't show more than is on the display.Pushing the Scale knob turns on the cool zoom mode, which lets you see the trace and a zoomed-in version at the same time, letting you zoom and pan.

Using the menus
Most of the menu buttons are in the group of 6 at the top. However, there's also a trigger menu button under the trigger knob and a time base menu under the horizontal position knob. This is in addition to the four vertical menu buttons: CH1, CH2, MATH, and REF.The menus hide about 1/6 of the display, so close the menu when you're done: push the round Menu On/Off button or push a menu button a second time.
Don't press Auto
The Auto button is right next to the Run/Stop button, so you might think it will set the trigger to Auto Sweep. Instead this button sets the controls to seemingly-random values to aotomatically display your traces. This is good if you're totally lost, but more likely to wipe out the settings you want.Screenshots
Some oscilloscopes make screenshots easy, but the Rigol is more complicated. To take a screenshot on the Rigol, plug a USB drive into the front panel, then hit the Storage menu button, select Bit map under Storage, select External, New File, and Save. This will save NewFile0.bmp to your flash drive. (It's much easier to rename the file on your computer than on the oscilloscope.)An alternative is to run the slightly clunky UltraScope software on your computer, which gives you access to the oscilloscope via USB. You can download "UltraScope for DS1000E" from the Rigol Software Applications page; although it has a PDF icon, it's actually a Zip file with the software.
Built-in help
If you hold down a button or knob for three seconds, the oscilloscope displays a help screen explaining its action. (I was surprised when I discovered this by accident.)
The built-in help feature of the Rigol DS1052E oscilloscope is triggered by holding down a button or knob.
Triggering
The three trigger sweep modes are Auto, Normal, and Single. Auto will keep displaying traces until you hit Run/Stop. Normal will display a trace every time the trigger condition is satisfied. Single will display a single trace when triggered and then stop. Auto is the way to see a waveform without worrying about triggering. But if you want a nice, stable waveform, set up the trigger and use Normal. Also make sure you're triggering from the right channel - the oscilloscope likes to default to using Channel 2 as the trigger.Controlling the channels
If you've used an oscilloscope with separate controls for each channel, you may expect the knobs near CH1 to control channel 1, and the knobs near CH2 to control channel 2. Instead, if you hit CH1, the knobs control channel 1's scale and position, while if you hit CH2, Math, or Ref, the same knobs control that channel's scale and position. Make sure you're controlling the trace you think you're controlling.Use the colored probe rings
Maybe this is too obvious to mention, but putting matching colored rings on both ends of the oscilloscope probes lets you easily tell which probe goes with which channel.
Label oscilloscope probes with colored rings that match the trace colors.
Cursors
The cursors are very handy to measure voltages, times between two points, frequency, etc. (The Measure mode provides lots of automated measurements, but often doesn't measure what you want.) Manual mode lets you position two cursors (either vertical or horizontal), and the positions and difference are displayed. Track lets you position a cursor along the waveform, and a voltage cursor automatically tracks the waveform. Both time and voltage values are displayed. Auto mode is the mode you should use with Measure, in order to see what the measurements mean.
A tracking cursor puts X-Y lines on the waveform and gives measurements.
