Techmaster Electronics is the authorized Keysight distributor in Vietnam for the Essential oscilloscope tier — the entry level in Keysight’s new Essential / Advanced / Expert / Pro structure (2025–2026). Essential covers 70 MHz to 1 GHz across three classes XR1, XR2, XR3, with 2–4 analog channels, optional 16 MSO digital channels, and 2–5 GSa/s sample rate. This is the right tier for university teaching labs, general electronics R&D, mid-tier board debug, and QA / production line replacement of aging benchtop scopes.
Why Essential rather than the older lineup. XR1/XR2/XR3 is how Keysight reorganized the familiar InfiniiVision catalog (1000X / 2000X / 3000X) into transparent capability tiers — same feature set (Zone Touch trigger, MSO option, serial bus decode, web remote) on the new HD3 platform. For Vietnamese university and R&D customers, Essential remains the best price-performance tier; no need to go Advanced unless you exceed 1 GHz or require specialized analysis. Techmaster has deployed this range at HUST, HCMUT, UTC, and many QA EMS labs in Bắc Ninh and Hải Phòng.
| Class | Bandwidth | Analog channels | Digital MSO | Sample rate |
|---|---|---|---|---|
| XR1 | 70 – 200 MHz | 2 or 4 | Up to 16 (option) | 2 GSa/s |
| XR2 | 200 – 500 MHz | 2 or 4 | Up to 16 (option) | 5 GSa/s |
| XR3 | 500 MHz – 1 GHz | 2 or 4 | Up to 16 (option) | 5 GSa/s |
Four value drivers: (1) HD3 platform — high-resolution touchscreen, modern UI, web remote via browser; (2) Zone Touch trigger — draw a region of interest with your finger to trigger on complex events, no programming; (3) MSO 16-channel option on the same scope, turning analog into mixed-signal when you need to debug parallel bus or digital control; (4) built-in protocol decode library (I²C, SPI, UART, CAN, LIN, FlexRay, USB, RS-232) — license-enabled, no extra hardware. For teaching labs, XR1 also has the EDU bundle (workbook, video tutorials, Keysight University curriculum) bundled by Techmaster.
| Model | Spec | Best for |
|---|---|---|
| HD3 (new) | New Essential platform, 12-inch touchscreen, web remote | Labs needing modern UI + remote ops |
| DSOX1102G / DSOX1204G | 70–200 MHz, 2/4 ch, 20 MHz integrated generator, EDU bundle | University teaching, entry R&D |
| DSOX2002A / DSOX2024A | 200 MHz, 2/4 ch, MSO 16-channel | General electronics R&D, serial bus debug |
| DSOX3012T (Essential tier) | 200 MHz – 1 GHz, MegaZoom, web interface | Mid-tier digital validation, basic signal integrity |
| Customer / application | Recommendation |
|---|---|
| University teaching (HUST, HCMUT, UTC) | DSOX1204G + EDU bundle + Keysight University |
| Mid-tier R&D (control board, IoT module) | DSOX2024A or HD3 4-channel + MSO option |
| EMS QA / production (Bắc Ninh, Hải Phòng) | DSOX2002A + Mask Test mode |
| Mid-tier digital validation (USB FS, JTAG, low-speed SerDes) | DSOX3012T + protocol decode |
| QA-line replacement for legacy benchtop | HD3 or 1000X/2000X depending on BW |
Essential serves well up to 1 GHz and 4 channels. Step up when: bandwidth > 1 GHz (Advanced XR4/5: 200 MHz–1.5 GHz; Expert XR6: 500 MHz–6 GHz; Pro XR8/9: 10–110 GHz); more than 4 analog channels (Expert up to 8); Gpts memory depth instead of Mpts; sample rate > 5 GSa/s for fast edges and jitter; specialized validation software (USB4, DDR5/6, PCIe Gen5/6 compliance) which only runs on Infiniium / MXR / UXR / XR8.

Every Essential scope Techmaster supplies can include: passive probes (N2862B 10:1 for XR1/XR2, N2873A active for XR3), MSO logic probe (N6459A), protocol decode licenses (D1000xxxA), BenchVue for PC control and data acquisition. For teaching bundles: Keysight U1881A power-measurement and U1882B video-application apps per curriculum.
Every Keysight oscilloscope Techmaster supplies includes manufacturer warranty plus ISO/IEC 17025 calibration on a 12-month cycle.
Essential is the new commercial label (2025–2026) for the 70 MHz–1 GHz segment. It includes 1000X, 2000X, and the front of 3000X reorganized into three classes XR1, XR2, XR3 on a single software platform. Existing 1000X/2000X customers are not affected — the products still ship.
Not entirely. HD3 is the new Essential platform with a larger screen, web remote, and modern touch UI — but the 1000X (especially DSOX1204G) remains the best teaching choice because of its integrated generator and EDU bundle.
Yes. Most Essential models can upgrade to MSO with 16 digital channels via software license + N6459A logic probe.
On 1000X and some 2000X you can upgrade bandwidth via license (e.g., DSOX1102G 70 → 100/200 MHz via D1100BWUA).
Yes. Keysight has EDU pricing for teaching labs with workbooks, video tutorials, Keysight University curriculum. Techmaster has deployed at HUST, HCMUT, UTC.
All Essential support LXI / USB / GPIB and integrate with BenchVue, PathWave Test Automation, LabVIEW, TestStand, Python (pyvisa). Web remote browser interface needs no driver install.
