Comprehensive test and measurement service provider-Shenzhen Weike Electronic Technology Co.
Scope of Application
Cell phone speakers, receivers, MP3, tablet PC, laptop PC speakers, low power TV speakers, etc.
Performance Characteristics
- This equipment is easy to operate, centralized settings, the menu bar without multi-layer nesting, display area, setting area clear and direct, in line with the requirements of the operator's habits, not easy to make mistakes.
- Signal source: built-in sine wave generator and sweep controller, can deposit various formats of audio files (e.g. white noise, pink noise, IEC268-5, analog programs, EIA, DIN, JIS, etc.), also supports MP3, WAV, and other formats, decoded and played by a professional computer sound card, more stable.
- Display content: two groups of voltage can be arbitrarily set 20-way simultaneous monitoring, automatic recording and display of voltage/current/DCR/temperature rise/test time and status; voltage and current real-time curve display.
- The test voltage is automatically corrected, the accuracy can reach ≤ 5%, display 0.001V;
- Panel 8-inch LCD, display content is richer, larger font, easy to observe; both real-time data display and real-time graphic display.
- Interface: Front panel signal data input interface (USB), rear panel LAN network port can be directly connected to the server, unified handling of all the machine data upload and other operations.
- Temperature rise measurement range: 0~200℃, measurement accuracy≤5%±1℃;
- Support multiple working modes: debugging, normal, intermittent. One of the small intermittent support 0.5s, debugging mode can maintain the output even without connecting the product.
- Filter: It can filter all kinds of internal signals 20Hz-20kHz, divided into straight-through, 2nd order band-pass filtering, 4th order band-pass filtering.
