Description
Overview
GAOTek High Performance LCR Digital Bridge Meter is a new generation of impedance test equipment with high accuracy, wide measurement range and six digits resolution. Being possessed with test frequency up to 100 kHz, test voltage of 10 mV to 2 V, built-in typical DC bias and –10 V to 10 V DC voltage source output, it can meet all requirements for measuring components and materials and provide guarantees for production line quality assurance, incoming inspection and laboratory precision measurements.
Features
- Simultaneously display four parameters in flexible combinations
- High-speed measurement Up to 65 meas/sec (with display)
- Built-in bias options 0 V, 1.5 V, 2.0 V, 4.0 V, or 5.0 V
- Adjustable independent DC source -10 V to 10 V with 2.5 mV resolution
- Instant measurement and result display upon trigger
- Powerful list sweep for mixed scans and parameter displays
- Nuanced analysis with frequency, level, bias, or DC source
- User correction with up to 32 frequency points
- Communication options RS232C, USB-CDC, USB-TMC, HANDLER, GPIB
- Save data, images, setup files on USB do U disk firmware upgrades
- Real-time parameter storage or recall without shutdown loss
- supporting internal storage of 100 groups
