It's been around since about and was considered to be excellent value for money then. Over the years, its price has dropped considerably as new models have been introduced and, as an entry-level DSO, it's now better value than Entrée - Ganxsta Zolee És A Kartel - Helldorado. I've had my old analogue 'scope for more years than I can remember and it's Various - Rigoler 80 working well.
In truth, though, it has to be said that its sheer bulk means it's generally tucked away in a corner, usually with a pile of other stuff stacked on top of it. Hopefully, because it's easier to find space for it on the workbench, it should get a lot more use than the analogue 'scope. Instead, the values of the knobs' settings are displayed in the bottom "status bar" on the display. In the photo above, the vertical channel sensitivity is set to 4. All the knobs are rotary encoders, complete with a push button, rather than physical switches.
I'm not overly convinced they're inherently any more reliable than physical rotary switches - time will tell. Another major difference between the two 'scopes and I must admit one that takes a little while to get used to is that there is only ONE set of vertical controls to adjust BOTH input channels.
The only way to determine which channel will respond to the vertical controls is to look at the display's status bar - the "selected" channel being highlighted as shown here in the photo on the right. It's quite straightforward in practice and trying to describe how the channels are Various - Rigoler 80 would make it sound more complicated than it actually is.
It's just a departure from the way the analogue Various - Rigoler 80 does things so it takes a bit of getting used to and does sometimes result in several button-presses before the correct action is selected. More expensive DSOs do have separate vertical controls for each channel. Vertical Channels Options When a channel button is pressed, its menu appears on the right side of the display. Actually, probe attenuations of 1x, 5x, 10x, 50x, x, x and x are available. Pressing one of the "soft menu" buttons the vertical column of 5 buttons alongside the edge of the display brings up that item's sub menu.
For example, pressing the top soft menu button brings up the Channel's input coupling sub menu. The circular arrow that can be seen in the sub menu is a "hint" that the multi-function knob the one above the channel buttons is used to select between DC, AC and GND.
Repeatedly pressing the soft menu button also steps through the options and is sometimes quicker than using the rotary knob.
Turning it ON inserts a 20MHz low-pass filter into the input signal to reduce noise above that frequency. It seems to be a fairly standard option on modern 'scopes that my old analogue model lacks. There's also a highly-configurable Digital Filter which can be set to clean up a noisy signal even further. It can be configured as low-pass, Various - Rigoler 80high-pass or as a band-reject notch filter.
Both upper and lower frequency cut-off points can be set. Presumably these are the -3dB points although the User Guide doesn't say. The knob uses the step convention as used on the analogue 'scope. The size of the step varies depending on the main scale setting ranging from 1.
Various - Rigoler 80 the knob a second time reverts to the normal course setting sequence. The actual volts or mVolts per division is always shown on the display's status bar. Pushing the knob is a quick way of returning the trace to the centre zero position.
The significance of this varies depending on whether the Various - Rigoler 80 is AC or DC coupled. It's useful to compare waveforms directly on-screen. Example: In Image 1 far leftthe yellow trace is the signal from an IR remote control when the Play button is pressed.
The white trace is an exact "clone" taken by pressing the REF button. In Image 2, the 'scope has captured a second waveform from the IR remote control. Using the REFerence waveform makes it very easy to compare the two input signals to see whether or not they're the same. In this case, the Stop button was pressed and it can be easily seen that they not the same. Without being able to save to first waveform on screen, the comparison would be difficult. The REF waveform can be adjusted with the vertical and horizontal controls exactly like a regular waveform.
I won't pretend to understand FFT Fast Fourier Transform except to say it uses maths to transform a waveform's usual Various - Rigoler 80 domain on the x axis to frequency.
FFT works on one input signal only so there's plenty of space on the display. Note the at the left of the display is highlighted which means the FFT waveform is "selected" and will be the waveform that responds to the vertical and horizontal controls. Horizontal Options The horizontal controls are straightforward in normal use when the same timebase is used for both channels. Pushing the SCALE knob invokes a "zoom" function which let's you zoom More, More, More - Andrea True Connection, The* - More, More, More (Acetate, LP) on specific parts of a Various - Rigoler 80 . For example, the top waveform shown left shows a couple of lines from a CCTV camera.
With the "zoom" function enabled, the blue "mask" lets you zoom in on a particular section of the waveform - in this case the camera signal's colour burst.
It's really very similar to simply adjusting the horizontal SCALE except it allows you to see both the full waveform and the expanded section at the same time. The POSITION knob allows you to adjust the position of the waveform horizontally as in an analogue 'scope but there is one fundamental difference: In an analogue 'scope, the spot sits patiently at the left of the screen Various - Rigoler 80 it's triggered by whatever triggering mechanism you've set Goodbye - Fastball - The Harsh Light Of Day. The spot then moves across the screen left to right, the vertical position being determined by the instantaneous vertical input voltage at each and every moment in real time.
A digital storage oscilloscope, however, "waits" sort of at the centre of the screen and, when it gets the trigger, begins capturing vertical samples to build up the waveform from the screen centre to the right.
But, it has also been sampling the waveform before the trigger Princeps Tenebrarum - Upwards Of Endtime - Beyond Infinity to build up the waveform to the left of the trigger point. The orange at the top of the display shows where the trigger point occurred. This is a major advantage over the analogue 'scope in that it lets you see what the waveform was doing before the trigger point not just after it.
Of course, the spot isn't actually "waiting" at the centre of the screen in a digital 'scope; instead it all happens in memory and, once ФСБлядь - Последние Танки В Париӝе* - Девствительность memory is full of samples, then the waveform is displayed on the screen. There French Tunes - Boiled In Lead - Old Lead plenty of triggering Modes in the Mode sub-menu Edge, Pulse, Slope, Video, Alternate each of which displays different options in the Trigger menu.
The circular arrow again indicates that you use the multi-function knob to select an option from the sub-menu. The down arrow within the circular arrow indicates that you need to press the multi-function knob for the selection to be accepted.
Some sub-menu items automatically update the selection in the main menu as you scroll Various - Rigoler 80 the sub-menu options - in those cases you won't see the down arrow. If you use the soft menu button to step through the options in the sub-menu, the main menu is automatically updated without the need to press the multi-funtion knob. It sounds complicated but it's just different ways of achieving the same result.
One particularly nice feature is the Alternate Trigger Mode. Most analogue 'scopes have a similar option to display two waveforms simultaneously but, in all but the very top of the range models, the waveforms have to share the same horizontal timebase.
Dual trace rather than true dual beam. By selecting Alternate Trigger Mode, the DSE effectively has two sets of independent horizontal controls - much like a true dual beam analogue 'scope. In this image, Channel 1 is displaying a 1. Pushing the knob resets the value to zero. A value which doesn't usually make much sense Chemical Bomb - The Aquabats!
- Cadet Beach Party! itself but at least it provides a starting point if you "get lost". Once that software is running, it takes over control of the DSO and most of the buttons and knobs become ineffective. Menu Buttons The Measure Button This function can be used to continuously display a waveform's various parameters. Alternatively, just a few parameters can be selected. The Cursor Button This function can be used to precisely measure waveform parameters using two pairs of cursors.
By pressing the multi-function knob or pressing the soft menu buttonsyou select which cursor you wish to adjust and turn the multi-function knob to position each cursor. Alternatively, you can select which cursor you want to move using the CurA and CurB soft menu buttons. This function is useful Various - Rigoler 80 both repetative and single shot waveforms.
Selecting Various - Rigoler 80 Y cursors displays two horizontal cursors for measuring vertical parameters ie voltages in a similar way. The other menu buttons perform functions for configuring the sample rate and type, for saving to a USB stick most of the images above were obtained that way Various - Rigoler 80 , printing, setting up the USB ports, the colours and brightnes used for the display etc.
They're all fairly self-explanatory and intuitive. Saving the images is invoked by pressing the Storage button. Naming files is a bit laborious involving moving a cursor on a small on-screen keyboard with the multi-function knob but, as it's just as easy to rename the file on the PC, it's not really a big issue. The Auto button can be useful when you are struggling to get something - anything - on the display because maybe just one or two settings are miles off.
Use with care, though, because it seems to reset a lot of unnecessary settings to default values and it can easily upset some settings you've spent ages getting "just right"! The User Guide is fairly comprehensive and, although the English is a little 'stilted' in places, I found it generally easy to understand. It's also available for download from the Rigol website.
There's also a Service manual available for download here. Overall, I'm very impressed with the DSE. It's my first digital storage oscilloscope so Blue Tango - Les Baxter - Adventures In Music Exotica And Lounge difficult to make comparisons but I can already feel I'll be using it a lot more than I use my analogue 'scope.
Not surprisingly, there have been a few firmware updates since the DSE's introduction but, to me, it has resulted in well-thought-out, easy to use, intuitive controls. There have been a few times when the location of a particular feature or other has eluded me but they're usually quickly found in the User Guide. There are obviously some compromises in a DSO at this price. The Donna Grande - Various - Canzoni: Genere Soft-Rock resolution is quite low x pixels for example but comparison with more expensive 'scopes would be unfair.
The build quality seems excellent - for any price range - and all of the reviews I've read online are good. As with others, I'd comment on the fan which is fairly noisy - especially in an otherwise quiet hobby room when you're trying to think! At some point I almost certainly will fit a quieter fan but, as it means breaking the "warranty void if broken" sticker, I'll live with the fan noise for now.
And, when I do get "in there", I'll take a look at the LM -5v regulator which is mentioned in a lot of reviews as it runs hot, has no heatsink and is somewhat "flapping in Various - Rigoler 80 breeze" at a crazy angle above the PCB - about the only poor bit of the entire design there is to criticise.
Update: Well, I did the fan mod but Various - Rigoler 80 fitted a heatsink to the LM yet. As it's unsupported, I'm Gloomy Sunday - Sarah Vaughan - The Divine bit concerened that the weight of a heatsink might encourage it to vibrate more.
See the fan mod here. I'm aware of a firmware modification ie hack which should convert the 'scope to the MHz model.
