Description
HTC DSO-10100S Digital Storage Oscilloscope – Dual-Function Precision in a Compact Package
The HTC DSO-10100S blends high-performance oscilloscope capabilities with a built-in DDS signal generator, offering a dual-function solution ideal for electronics developers, technicians, and educators. With a substantial 100 MHz bandwidth, 1 GS/s real-time sampling rate, and an expansive 7″ LCD, this tool delivers clarity, versatility, and intuitive usability.
Dual-Core Capabilities: Oscilloscope Meets Signal Generator
-
Dual-Channel Oscilloscope: Captures two simultaneous signals with up to 100 MHz analog bandwidth and 1 giga-sample per second real-time sampling—ideal for fast transient analysis.
-
Built-In DDS Signal Generator: Offers 14 standard waveforms—sine, square, triangle, sawtooth, reverse sawtooth, ladder, half-wave and full-wave rectified, exponential, logarithmic, pulse, multi-audio, and sink pulses—each delivered at 2.5 Vpp with full frequency resolution down to 1 Hz. Custom cut-off waveforms and step frequency control offer unmatched flexibility.
Precise Wave Capture & Measurement
-
Vertical Sensitivity spans from 50 mV/div to 500 V/div—providing adaptability from low-millivolt signals to high-voltage diagnostics.
-
Horizontal Timebase ranges from 10 ns/div to 50 s/div, suitable for capturing microsecond pulses to slow waveform trends.
Advanced Triggering & Input Management
-
Mode options include Single, Normal, and Auto triggering, with rising or falling edge selection.
-
Internal trigger levels adjustable up to ±5 divisions; external input supports ±3 V or ±15 V for broader applicability.
-
Input coupling via AC/DC, with high input resistance of around 1 MΩ, and probe limits set to 40 V (1×) or 400 V (10×) safely.
Smart Visualization & Control
-
Features a stunning 7-inch TFT LCD with 800 × 400 resolution, offering clear waveform display and analysis.
-
Built-in 1 GB of storage accommodates 1,000 screenshots and 1,000 sets of waveform data, enabling efficient test tracking and data recall.
Measurement & Analysis Functions
-
Cursor measurements available for voltage difference (ΔV), time difference (ΔT), and frequency (1/ΔT).
-
Built-in calculation of key signal metrics: peak-to-peak, max/min, average, RMS, frequency, duty cycles, pulse widths, rise/fall times, and more.
-
Supports mathematical operations (+, –, ×, ÷, %) on waveform data.
-
Lissajous pattern mode offers phase comparison with ±3° resolution.
Enhanced Workflow & Usability
-
One-Button AUTO automatically adjusts display scaling and trigger position.
-
One-Touch Screenshot Storage simplifies capturing and recalling screen visuals.
-
Supports USB output for waveform export and data sharing.
-
Fully compliant with 100–240 VAC, 45–440 Hz, CAT II power standards. Power consumption remains under 30 VA.
Built to Last & Field-Ready
-
Overvoltage Protection: Handles up to 400 V on 10× probe without damage.
-
Compact Form Factor: Measures 310 × 145 × 70 mm, weighing around 2–4 kg including packaging.
-
Comes with two 100 MHz probes, USB charger, and user manual—included for immediate setup.
Why the DSO-10100S Stands Out
-
All-in-One Solution: Combines oscilloscope and signal generator in a single, space-saving device.
-
Wide Operational Range: Designed for applications from hobbyist electronics to industrial R&D.
-
User-Friendly Interface: Large LCD, intuitive AUTO setup, and cursor tools reduce learning curves.
-
Data Versatility: Internal storage and USB connectivity streamline documentation and sharing.
-
Built for Durability: Reliable power ratings, input protection, and compact design support daily use in lab or workshop.
