USB-OC is standard accessory of the EHP-50G Analyzer.
It converts the signals of some of the system’s accessories, which are only
connected via fiber optic, into USB-compatible signals. It, therefore, makes
it possible to link the following items up to the USB port of any Personal
Computer to operate them in conjunction with specific application software
and for firmware updating:
• EHP-50G Electric and Magnetic Field Analyzers, 1Hz-400kHz
•
EHP-200A Electric and Magnetic Field Analyzers, 9kHz-30MHz
• NBM550 Broadband meter
Either USB-OC or 8053-OC is indispensable for updating the internal
firmware of the above-mentioned items via a Personal Computer and the
