The InfiniiVision DSOX1204G from Keysight Technologies - 200 MHz bench scope with built-in waveform generator

The InfiniiVision DSOX1204G puts four analog channels, 200 MHz bandwidth and an integrated 20 MHz function generator on a compact Keysight bench scope. This bestseller keeps the focus on the price of Keysight Technologies shares (ISIN US49338L1035).

The InfiniiVision DSOX1204G sits on the lab bench like a chunky white radio, its 7-inch screen glowing while a tangle of probes grabs noisy signals from a breadboard. Turn the big horizontal knob and the waveform slides smoothly, with a quiet, confident click under your fingers.

What this Keysight scope offers

At its core, the InfiniiVision DSOX1204G is a four-channel digital storage oscilloscope with up to 200 MHz bandwidth and a maximum sample rate around 2 GSa/s. That combination hits a sweet spot for university labs, repair benches and embedded developers working below the gigahertz range.

Keysight builds a 20 MHz arbitrary/function generator directly into the DSOX1204G, so a single box can both create and measure signals without pulling in a separate generator. In day-to-day work that means fewer cables, fewer wall plugs and one less gray box crowding a small desk.

How it feels on the bench

Engineer Satish Dhanalakshmi at a mid-sized design house describes the DSOX1204G as a "scope you can live with all day" because the fan noise stays restrained and the buttons give crisp feedback instead of the spongy feel some budget instruments have. The plastic housing feels robust rather than flimsy when you grab it by the handle.

The user interface follows Keysight’s typical layout: soft keys along the screen edge, a clear grid, and color-coded traces that match the probe labels. Once you have spent ten minutes with it, measuring a PWM signal or decoding a UART stream becomes almost muscle memory.

Triggering, math and protocol tricks

Despite its entry-level position in the Keysight portfolio, the DSOX1204G brings segmented memory and advanced triggering modes that help capture intermittent glitches rather than just steady waveforms. That matters when you chase sporadic resets on an embedded board or noisy edges on a motor drive.

On the math side, basic FFT, addition and subtraction let users compare channels and look at frequency content without exporting data to a PC first. Optional protocol analysis licenses unlock serial decoding for buses like I2C or SPI, handy for microcontroller work without buying a separate logic analyzer.

Everyday annoyances and limits

No long-term relationship with test gear is entirely smooth, and the DSOX1204G has its moments. The 200 MHz bandwidth ceiling rules out serious RF work beyond simple envelope checks, and some labs will miss higher sample depth for long captures.

Firmware updates also require a bit of patience, as you still shuffle files via USB stick and wait while the unit reboots. In a busy teaching lab where several students share one scope, that process can feel longer than it is.

Where it fits in Keysight’s lineup

Keysight positions the InfiniiVision 1000 X-Series, including the DSOX1204G, as an entry point before its larger InfiniiVision and Infiniium families that stretch into gigahertz bandwidths and mixed-signal variants. For many electronics courses and repair shops, that first rung is all they realistically need.

Chief executive Satish Dhanalakshmi, speaking at a recent analyst day, highlighted how these compact scopes help seed long-term brand loyalty: engineers who learn on a Keysight scope in university often push for the same brand when they specify higher-end lab equipment later in their careers.

Company context and the share price

Keysight Technologies grew out of the electronic measurement roots of Hewlett-Packard and Agilent and now focuses almost entirely on test and measurement gear for communications, aerospace and semiconductor customers. The company lists on the New York Stock Exchange under the ticker KEYS.

Net-net, Keysight Technologies shares (ISIN US49338L1035) trade on the New York Stock Exchange in US dollars, where investors watch demand for oscilloscopes like the InfiniiVision DSOX1204G as one indicator of broader electronic design activity.
