Key Features
50 MHz Dual-channel Entry Scope
SDS1000DL+ is intended for basic waveform capture, service troubleshooting, education labs and low-cost production checks where a simple two-channel oscilloscope is sufficient.
500 MSa/s Real-time · 50 GSa/s Equivalent-time
The scope supports 500 MSa/s real-time sampling and 50 GSa/s equivalent-time sampling for repetitive signals.
Up to 32 kpts Memory
Long Memory mode helps retain more waveform detail than very shallow-memory entry scopes, with zoom support for focusing on selected waveform sections.
32 Automatic Measurements
The platform supports voltage, time and delay measurement categories with 32 parameters, and can display up to five selected measurements on screen.
Math, FFT and Zoom
Math functions include addition, subtraction, multiplication, division and FFT, with split or overlay display modes for waveform analysis.
Pass/Fail and Recorder Functions
Pass/fail mask testing and digital recorder functions make the unit usable for long-term observation and simple production-line checks.
7-inch TFT-LCD Display
The 800 × 480 display provides enough screen area for waveform view, measurements, menus and embedded help.
USB, LAN and Pass/Fail Interfaces
Interfaces include USB Host, USB Device/USBTMC, LAN/VXI-11 and Pass/Fail output for bench and remote use.

Applications
Basic Oscilloscope Training
Cost-effective 2-channel platform for teaching waveform capture, triggering, measurement parameters, FFT and signal observation.
Repair and Troubleshooting
Suitable for checking power rails, clocks, sensor outputs, relay signals and low-speed analog/digital waveforms on service benches.
Simple Pass/Fail Checks
Mask-based pass/fail testing and recorder functions support basic production and burn-in observation workflows.
MCU and Board Bring-up
Useful for basic microcontroller bring-up, reset timing, clock checks, PWM observation and power-on sequence debugging.
Entry-level Power Checks
Can support basic ripple, switching waveform and transient observation on low-bandwidth power electronics applications.
Low-cost Bench Measurement
A practical entry-level choice where budget and simple two-channel measurement are more important than deep protocol or high-bandwidth analysis.
