Best Usb Oscilloscope

[Ane Neemann]

Lookingfor the right oscilloscope for your electronics projects or professional endeavors? This guide provides a clear framework to identify the oscilloscope that best aligns with your requirements, whether you're a seasoned engineer, a student, or an electronics hobbyist. We'll explore key parameters such as bandwidth, sample rate, and rise time, ensuring you make an informed choice that enhances the precision and efficiency of your measurements.

A Mixed Signal Oscilloscope adds digital timing channels, which indicate high or low states and can be displayed together as a bus waveform. Whatever you choose, all channels should have good range, linearity, gain accuracy, flatness, and resistance to static discharge.

High-voltage differential probes: Differential probes allow a ground-referenced oscilloscope to take safe, accurate floating and differential measurements. Every lab should have at least one.

A good basic scope for example will store over 2,000 points, which is more than enough for a stable sine-wave signal (needing perhaps 500 points), whilst more advanced high-end scopes would have up to 1Gpoints, which is essential for working with high-speed serial data type applications.

Oscilloscopes with high waveform capture rates provide significantly more visual insight into signal behavior, and dramatically increase the probability that the oscilloscope will quickly capture transient anomalies such as jitter, runt pulses, glitches and transition errors.

Digital storage oscilloscopes (DSO) employ a serial processing architecture to capture from 10 to 5,000 wfms/s. Some DSOs provide a special mode that bursts multiple captures into long memory, temporarily delivering higher waveform capture rates followed by long processing dead times that reduce the probability of capturing rare, intermittent events.

Most digital phosphor oscilloscopes (DPO) employ a parallel processing architecture to deliver vastly greater waveform capture rates. Some DPOs can acquire millions of waveforms in just seconds, significantly increasing the probability of capturing intermittent and elusive events and allowing you to see the problems in your signal more quickly.

The bandwidth of an oscilloscope defines the range of frequencies it can accurately capture. It is the -3 dB point on the frequency response curve, indicating the upper limit of the signal frequency that can be properly measured. Higher bandwidth oscilloscopes can capture and display signals with higher-frequency components more accurately. Lower bandwidth oscilloscopes may distort or attenuate high-frequency content, leading to inaccuracies in signal representation. The bandwidth of an oscilloscope is closely related to its rise time, which is the time it takes for the voltage to transition from 10% to 90% of its final value. A higher bandwidth oscilloscope has a faster rise time, allowing it to capture and display fast edge transitions more accurately.

The sample rate of an oscilloscope defines how many data points the oscilloscope records per second. Higher sample rates allow the oscilloscope to capture and represent rapid changes in voltage over time. A high sample rate helps prevent aliasing, which occurs when an oscilloscope undersamples a signal with high-frequency components. Incorrect representation of the signal leads to measurement errors. To accurately reconstruct and display a signal on the oscilloscope's screen, you need enough data points within each waveform period. A higher sample rate provides more data points and allows for more precise signal representation.

I was wondering if someone could point me to a suitable Oscilloscope under $300 for side channel analysis? I presume it should be something like 200M/s and capable of handing input from portable devices. Anyone have good buys?

I am not very familiar with attacks on software implementations (I am mostly into attacks on hardware implementations) but one thing is for sure, the power signal of a cryptographic hardware implementation varies a lot from the power signal of microprocessor running a cryptographic algorithm, in terms of TIME.

A microprocessor takes a lot of clock cycles to run the commands of a software cryptographic algorithm, so the next most important thing (after the bandwidth of your oscilloscope) is the memory buffer inside your oscilloscope that saves the acquired traces. It is also good for your oscilloscope to have a fairly good resolution (probably better than 8-bit) because I believe that a microprocessor is a lot noisier than an FPGA.

On the other hand, a hardware cryptographic implementation running inside an FPGA takes a few clock cycles to finish, because many processes run in each clock cycle. So apart from the oscilloscope bandwidth, the most important thing in order to be able to catch a pretty useful signal for your attacks is the SAMPLING RATE of your oscilloscope (which is not independent from the oscilloscope Bandwidth). Your point in the hardware implementations is to catch the spikes that happen between each clock cycle. Those spikes are more dependent on the technology of the transistors inside the FPGA and the critical path they form in your implementation, rather than the clock your hardware implementation runs on.

So to sum-up:

Software implementations: sampling rate in order of Ms/s should be pretty enough.

Hardware implementations: sampling rate should start from 2Gs/s and above, in order to be sure that you get a fair signal for analysis.
