Keysight 1000X Oscilloscope: "Upgradeable + Cost-effective" for 50-200MHz Applications

When choosing an oscilloscope for 50MHz to 200MHz electronic testing applications, it's necessary to not only confirm whether functions match your requirements, but core specifications that determine test accuracy and fault capture efficiency, including sample rate, memory depth and waveform update rate, are also critical. Keysight InfiniiVision 1000X features multi-instrument integration, flexible model options and upgradeable bandwidth, along with core specifications perfectly matching application requirements, making it a popular choice for education, industrial R&D and electronic maintenance.

Product Portfolio: Detailed Specifications Tailored for Specific Applications

The 1000X series is divided into two sub-series:   EDUX (for education) and DSOX (for industrial/R&D applications)  

Besides the difference between basic and additional functions, the differentiated core specifications of A/G models also accurately match different requirements:

* Note: For EDUX series, "+1" means the external trigger can be used as a digital channel; DSOX series features pure analog channel design.

How do these parameters affect testing? Here is an example:

• Sample Rate: A high sample rate of 2GSa/s is just like a "high-speed camera" that can accurately "freeze" the details of high-speed signals (such as the rising edge of pulse signals and minor distortion of high-frequency signals), avoiding waveform distortion caused by insufficient sampling;

• Memory Depth: A large memory depth of 2 Mpts allows recording waveform changes over a longer period (such as capturing several seconds of data packet interaction on the communication bus and voltage fluctuation during power start-up);

• Waveform Capture Rate: Up to 200,000 waveforms per second ultra-high capture rate can quickly capture "rare glitches" or "bus errors" (in industrial scenarios, such intermittent faults are the most likely to be missed, but may lead to equipment downtime).

Model A vs Model G: Real Case + Parameter Logic Guide You to Select the Right Oscilloscope

We have served a large number of customers, and two typical scenarios can intuitively explain the selection logic for Model A/G:

Industrial Customers Choose Model A: Existing equipment + sufficient parameters are more practical and cost-effective

A small enterprise that manufactures industrial control boards in Shenzhen finally chose DSOX1204A. The person in charge of the enterprise explained: "Our laboratory has long been equipped with an independent function generator, so the built-in WaveGen of Model G is 'redundant functionality' for us; moreover, the 2GSa/s sampling rate and 2M point memory depth of DSOX1204A are fully sufficient for measuring RS-232 signals of PLC and IGBT driving waveforms, and the capture rate of ≥200,000 waveforms per second can also capture intermittent error frames on the CAN bus. The money we save allows us to buy more probes for the production line, which is more practical for us."

Such customers often already have part of the test equipment, or the test scenario only requires "basic signal observation + serial protocol analysis". The core parameters of Model A (high sampling rate, large memory depth, high waveform capture rate) can already cover the demand, and additional functions become "unnecessary costs".

Choice of G for Educational Institutions: Integration + Parameter Adaptation for More Efficient Teaching

An electronic laboratory of a university in Xi'an purchased EDUX1052G. The lab teacher did an "efficiency calculation": "The 1GSa/s sampling rate and 200k point memory depth of EDUX1052G are sufficient to cover all signals required for teaching experiments, such as sine waves, square waves, and small signal amplified waveforms. It comes with a built-in 20MHz function generator, so when students conduct RLC resonance experiments, they can directly generate the excitation signal without additional handling of external instruments. The Bode plot function can display the 'frequency-amplitude/phase' response curve in real time, which is far more efficient than pure theoretical explanation."

Educational scenarios value "integrated teaching tools + supporting resources" more. The combination of additional functions and core parameters of the G model can directly serve experimental courses, so it is more favored.

DSOX1204A, "Versatile & Cost-effective" for Industrial Scenarios

In the industrial field, DSOX1204A is recognized as a "versatile model", whose core advantages are reflected in both "parameters + scenarios":

• 4 channels + high specifications, complete complex tests in one go: When debugging industrial inverters, 4 channels can simultaneously capture "4-channel IGBT drive signals + 1-channel power signal"; The 2GSa/s sampling rate can accurately capture the rising/falling edges of drive pulses (edge distortion often causes IGBT overheating); The 2M point memory depth can record several seconds of waveform changes, which is convenient for observing signal fluctuations during startup; With a capture rate of ≥200,000 waveforms per second, it can also capture "narrow glitches" in drive signals (such glitches easily cause IGBT false triggering);

• Comprehensive Protocol Analysis, Full Industrial Bus Coverage: It comes standard with I²C, SPI, CAN, LIN and other protocol decoding. During production line debugging, it can directly analyze the "data interaction timing" and "error frame content" on the industrial bus, and quickly locate problems such as "communication timeout" and "data packet loss";

• Upgradeable Bandwidth, No Waste in Long-term Use: If you currently test the RS-232 signal of PLC with 70MHz, and need to test 200MHz high-speed SPI signals in the future, you only need to purchase the "bandwidth upgrade option". The core parameters (sampling rate, memory depth, waveform capture rate) can still meet the new requirements, there is no need to replace the whole instrument, which effectively controls long-term costs.
