A comprehensive testing system suitable for car audio systems, amplifiers, and Blu ray DVDs, including audio analyzers, video analyzers, and AM/FM signal generator modules

VP-7671L supports high-definition video testing, while VP-7670L supports standard definition video testing

• Modules can be freely selected to meet different testing needs
• Support direct operation and automatic testing (active and passive) modes
• Automatic testing can be achieved through simple settings (active mode)
• Remote control can be achieved through passive mode and LAN connection
• Due to product characteristics, the overall testing cost has decreased
