The measured voltage Vx is input to the oscilloscope’s Y-axis channel, adjust the sensitivity of the Y axis, select the switch “V/div” and its fine adjustment knob, so that the screen displays a convenient measurement height Hx and make records, and V/div” switch and the fine adjustment knob position remains unchanged. SIGLENT oscilloscopes feature innovative digital trigger systems with high sensitivity and low jitter, high waveform capture rates (up to 110,000 wfm/s (normal mode), 480,000 wfm/s (sequence mode)), Many also employ the common 256-level intensity grading display function and color temperature display mode to make troubleshooting even easier. As you can see in these specs, the scopes are not far apart, the GW Instek has a larger memory for the signals and a higher waveform capture rate, but the Rigol does have a trigger output, for example. Up-to-date pricing and reviews for 4-Channel oscilloscopes on the market can be found at the oscilloscope models website.
If more than one measurement channel is used at the same time, all the input signals must have the same voltage reference, and the shared default reference is the “earth”. This is in contrast to the FFT functionality of conventional digital oscilloscopes which use the normal analog inputs. It provides the ability to accurately time-correlate analog and digital channels, thus offering a distinct advantage over a separate oscilloscope and logic analyser.
In the case of digital oscilloscopes, an analog-to-digital converter (ADC) changes the measured voltages into digital information. (Real time digital oscilloscopes offer the same benefits of a dual-beam oscilloscope, but they do not require a dual-beam display.) The disadvantages of the dual trace oscilloscope are that it cannot switch quickly between traces, and cannot capture two fast transient events. Greatly increased sample rates have largely eliminated the display of incorrect signals, known as “aliasing”, which was sometimes present in the first generation of digital scopes.
Better quality general purpose oscilloscopes include a calibration signal for setting up the compensation of test probes; this is (often) a 1 kHz square-wave signal of a definite peak-to-peak voltage available at a test terminal on the front panel. For a digital oscilloscope, a rule of thumb is that the continuous sampling rate should be ten times the highest frequency desired to resolve; for example a 20 megasample/second rate would be applicable for measuring signals up to about 2 megahertz. Beam-splitter types had horizontal deflection common to both vertical channels, but dual-gun oscilloscopes could have separate time bases, or use one time base for both channels.
More sophisticated analog oscilloscopes contain a second timebase for a delayed sweep. For a period of time, called holdoff, (extendable by a front-panel control on some better oscilloscopes), the sweep circuit resets completely and ignores triggers. Dual-trace oscilloscopes have a mode switch to select either channel alone, both channels, or (in some) an X‑Y display, which uses the second channel for X deflection.
Each input channel usually has its own set of sensitivity, coupling, and position controls, though some four-trace oscilloscopes have only minimal controls for their third and fourth channels. The Metrix 300MHz Handheld Oscilloscope offers a large touch screen 7″ colour LCD with 4 channel digital Multimeter 8000cts, FFT function and recording mode, and power measurement. RS Pro IDS-2000E Series digital storage oscilloscopes offer features normally only available on much higher-priced scopes or as expensive add-ons.
Mixed Domain Oscilloscope, MDO: Can operate in more than one domain, i.e. in time to display waveforms and in frequency to display signal spectra. Phosphor oscilloscopes (DPO): use a parallel processing architecture to enable it to capture and display signals. An Oscilloscope, also known as -scope, is a complex electronic laboratory instrument commonly used to capture, process, display and analyse the waveform and bandwidth of electronic signals.
Ideally we could all afford a MSO with 4 analog channels and 16 digital channels so we could look at plenty of signals and easily correlate them in time but at some point it gets pricey unless you have a pretty compelling need, cost-justification, or healthy budget.

I have a 2-channel siglent scope, and if I could halve it’s bandwidth for another two channels, I would do it in a heartbeat; that would let you look at all 4 lines of an SPI bus, and it makes it a decent substitute for a logic analyzer (and – I don’t know about others, but I quite recently had a problem with an SPI bus that I don’t think would have been so obvious on an LA – the fets I was using to level shift it had too high of a gate capacitance for the microcontroller to drive effectively at the speed I was clocking the bus at, so instead of nice square signals, I got this ugly smeared out waveform. In this segment a number of 2 channel oscilloscopes are available, but at the time of writing (February 2016) only 2 four channel scopes. A large number of instruments used in a variety of technical fields are really oscilloscopes with inputs, calibration, controls, display calibration, etc., specialized and optimized for a particular application.
There is a variation of the DSO called the digital sampling oscilloscope which can exceed this limit for certain types of signal, such as high-speed communications signals, where the waveform consists of repeating pulses. The dual-beam analog oscilloscope can display two signals simultaneously. Analog scopes do not necessarily include a calibrated reference grid for size measurement of waves, and they may not display waves in the traditional sense of a line segment sweeping from left to right.
The earliest and simplest type of oscilloscope consisted of a cathode ray tube , a vertical amplifier , a timebase, a horizontal amplifier and a power supply These are now called “analog” scopes to distinguish them from the “digital” scopes that became common in the 1990s and later. Analog oscilloscopes have been almost totally displaced by digital storage scopes except for use exclusively at lower frequencies. First appearing in the 1970s for ignition system analysis, automotive oscilloscopes are becoming an important workshop tool for testing sensors and output signals on electronic engine management systems, braking and stability systems.
All but the simplest models of current oscilloscopes more often use digital signal sampling. To catch these events, some oscilloscopes—called storage scopes—preserve the most recent sweep on the screen. A sampling oscilloscope can display signals of considerably higher frequency than the sampling rate if the signals are exactly, or nearly, repetitive.
The range of frequencies an oscilloscope can usefully display is referred to as its bandwidth Bandwidth applies primarily to the Y-axis, though the X-axis sweeps must be fast enough to show the highest-frequency waveforms. Some analogue oscilloscopes feature a Z input. This is especially useful for graphing I-V curves ( current versus voltage characteristics) for components such as diodes , as well as Lissajous patterns Lissajous figures are an example of how an oscilloscope can be used to track phase differences between multiple input signals.
Most modern oscilloscopes have several inputs for voltages, and thus can be used to plot one varying voltage versus another. In an analog oscilloscope, the vertical amplifier acquires the signals to be displayed and provides a signal large enough to deflect the CRT’s beam. Multi-trace oscilloscopes also switch channels either in chopped or alternate modes.
Compared to older, simpler oscilloscopes with continuously-running sweep oscillators, triggered-sweep oscilloscopes are markedly more versatile. It can be an external input, one of the vertical channels of a dual or multiple-trace oscilloscope, or the AC line (mains) frequency. Such oscilloscopes also are likely to have a trace separation control for multiplexed display of both the main and delayed sweeps together.
Multiple-trace oscilloscopes have a switch for each channel to enable or disable display of the channel’s trace. For convenience, to see where zero volts input currently shows on the screen, many oscilloscopes have a third switch position (usually labeled “GND” for ground) that disconnects the input and grounds it. Often, in this case, the user centers the trace with the vertical position control. In all but the least-costly modern oscilloscopes, the sweep speed is selectable and calibrated in units of time per major graticule division.
The biggest distinction is whether they are digital or analogue oscilloscopes. 200 MHz bandwidth, 4 channels, 1 GS/s Real-Time and 25GS/s equivalent-Time Sampling; 25 K point record length for analyzing complex signals; Large 5.6-in Ultra-bright TFT Color Wide-angle viewable area, 8 X 12 Division display; Three USB ports and one RS232 (standard). The majority of the screen is used for the scope display with a maximum of four simultaneous signals, at the bottom the most important measurements are continuously visible.
The XDS series oscilloscopes from the Chinese brand OWON has a number of features that you do not (yet) find on comparable models from other brands, and all that for a very sharp pricing. Digital oscilloscopes can be classified into digital storage oscilloscopes (DSOs), digital phosphor oscilloscopes (DPOs), mixed domain oscilloscopes (MDOs), mixed signal oscilloscopes (MSOs), and digital sampling oscilloscopes. Oscilloscopes can be classified in two major categories – analog and digital types.
