The InfiniiVision 4000A/G X-Series is designed for engineers who need flexible debugging and measurement capabilities across a wide range of applications. These oscilloscopes provide bandwidths from 200 MHz to 1.5 GHz and sampling rates up to 5 GSa/s for accurate capture of fast-changing signals. A 12.1-inch capacitive touchscreen makes operation intuitive, with touch gestures for zooming, panning, and trigger setup. The series includes both 4000A and 4000G variants, with the 4000G models shipping with more features enabled as standard. With waveform update rates above 1,000,000 waveforms per second, the instruments are well suited to finding intermittent glitches and rare events. InfiniiScan Zone touch triggering helps users isolate signal anomalies quickly by drawing a trigger area directly on the screen. Mixed-signal models support digital logic analysis alongside analogue measurements for embedded system debugging. Integrated tools such as a waveform generator, digital voltmeter, and frequency counter reduce the need for additional bench instruments. Deep segmented memory and hardware-accelerated protocol decoding further expand the scope of analysis. The platform is also license-upgradable, allowing users to add capabilities over time as requirements evolve.
The InfiniiVision 4000A/G X-Series combines high bandwidth, fast update rates, and intuitive touchscreen operation in a versatile oscilloscope platform. It is well suited to electronics debugging, embedded design validation, power analysis, automotive troubleshooting, and semiconductor testing.
The range includes both 2-channel and 4-channel models, with mixed-signal versions adding 16 digital logic channels for time-correlated analogue and digital analysis. 4000G models include more advanced functions as standard, while 4000A models offer a lower entry point with upgrade paths for future expansion.

Model note: DSOX models provide analogue-only input channels, while MSOX models add 16 digital logic channels for mixed-signal analysis. Mixed-signal capability may require the appropriate logic probe and license depending on the purchased configuration.
4000A vs 4000G: Both variants share the same core oscilloscope hardware performance, but 4000G instruments include more advanced capabilities as standard, such as waveform generation, hardware serial decoding, mask testing, and frequency response analysis.
FAQs
for InfiniiVision 4000A/G X-Series Oscilloscopes
Both versions share the same core oscilloscope hardware, including bandwidth options, channel configurations, sampling performance, and touchscreen operation. The main difference is that 4000G models include more advanced features as standard, such as the dual-channel waveform generator, hardware-accelerated serial decoding, mask testing, and frequency response analysis.
The 4000A models start from a lower base configuration and allow these functions to be added later through upgrade licenses, giving users more flexibility in how they build out the instrument.
Yes. The platform is designed to be field-upgradeable. Users can add software options later, including serial protocol decoding, advanced analysis tools, and other licensed features.
If you start with a DSO model, it is also possible to move to mixed-signal capability by adding the required logic probe and enabling the appropriate license, allowing the oscilloscope to support 16 digital logic channels.
In addition to oscilloscope functionality, the series includes a built-in digital voltmeter and frequency counter for quick bench measurements. It also supports an integrated function or arbitrary waveform generator, which is standard on 4000G models and optional on 4000A models.
These added tools help reduce the need for separate instruments during development, validation, and troubleshooting tasks.
Zone touch triggering allows the user to draw a region directly on the screen around the waveform behavior of interest. The oscilloscope then triggers when a signal enters or intersects that region.
This makes it much faster to isolate abnormal spikes, glitches, or timing events without building complex trigger setups manually, which is especially helpful when troubleshooting intermittent issues.
Yes. With the appropriate options enabled, the InfiniiVision 4000A/G X-Series can decode common serial protocols such as I2C, SPI, UART, CAN, LIN, I2S, and USB.
Because decoding is hardware-accelerated, the instrument can display decoded information more responsively and support triggering on protocol-level events, helping engineers debug embedded communications more efficiently.
