As a core electronic measurement device, oscilloscopes analyze parameters such as frequency, amplitude, and phase by capturing and displaying electrical signal waveforms. They are widely used in electronic R&D (chip/PCB testing), industrial debugging (power equipment signal monitoring), communications maintenance (base station signal detection), and educational experimentation. They are primarily categorized into “benchtop laboratory oscilloscopes” and “portable field oscilloscopes”: The former requires stable power supply for extended continuous measurements, while the latter prioritizes outdoor mobility and battery endurance. Both impose specific demands on power supply voltage accuracy, interference resistance, and structural compatibility.
Core Power Supply Challenges for Oscilloscopes
The measurement characteristics and application scenarios of oscilloscopes present multiple critical issues in power usage, directly impacting measurement accuracy and operational efficiency. Specific challenges include:
Measurement Errors Caused by Power Fluctuations: During startup (including probe warm-up and signal acquisition module activation), oscilloscopes experience a sudden surge in instantaneous power consumption (e.g., multi-channel models may peak at over twice their normal operating power). Yet during measurement, stable low-power output is required. Traditional batteries that cannot rapidly respond to power fluctuations often exhibit voltage variations exceeding ±0.1V. This causes waveform distortion and data drift, necessitating recalibration and increasing time costs.
The trade-off between endurance and portability: Portable oscilloscopes require a single charge to support over 4 hours of field testing outdoors (e.g., outdoor equipment debugging, base station signal troubleshooting), yet the total weight must be kept under 5kg (for single-person portability). Traditional batteries either suffer from “insufficient endurance” (powering down within 2 hours) or “excessive weight” (individual cells exceeding 600g), making it difficult to balance “long endurance” and “lightweight” requirements;
Power instability in harsh environments: Electromagnetic interference in industrial workshops and dust can clog battery ports or disrupt power supply stability, causing measurement signals to suffer from noise interference. Mild splashes or oil contamination in certain scenarios may also trigger battery short circuits, interrupting measurements and limiting multi-scenario adaptability.
Dual safety and compliance barriers: Oscilloscopes used in industrial quality inspection and communication equipment testing require batteries with comprehensive protection features against overcharging, over-discharging, overcurrent, and overtemperature. Additionally, they must meet safety certifications for major global markets (e.g., UL and CE in Europe/America; KC and PSE in Asia). Uncertified products cannot be exported with oscilloscopes, complicating device market entry.

Tefoo Core Advantages (Key Highlights)
(1) No Minimum Order Quantity, Flexible Demand Adaptation
Whether for small-batch lab trials (1-2 units) or factory bulk purchases (thousands of units), we offer immediate stock availability with no MOQ restrictions. Eliminate concerns about “unable to order small quantities,” reducing procurement trial-and-error costs and inventory pressure—ideal for small-batch oscilloscope requirements during R&D phases.
(2) Full-process customization services for specialized requirements
For non-standard oscilloscope needs (e.g., irregular battery compartments, special voltages, custom interfaces, high protection ratings), we provide end-to-end customization services from design to mass production (OEM clients only). Our solutions overcome arc-shaped structure limitations—for instance, creating batteries under 12mm thick for ultra-thin portable oscilloscopes or IP67-rated batteries for industrial-grade oscilloscopes. This ensures deep compatibility between batteries and devices, resolving “standard product incompatibility” issues. Customization processes and standards are fully documented.
(3) Comprehensive Certification for Global Market Access
All battery and charging products hold safety certifications (UL 1642, IEC 62133, UN38.3, GB31241), environmental certifications (RoHS 2.0, REACH), and market access certifications (CE, FCC, KC, PSE, UKCA, CCC). These cover major global markets including North America, Europe, and Asia, eliminating the need for additional certification applications and accelerating time-to-market.
