GX2475： High voltage dual channel digitizer PXI board

• Dual channel, 14 bit digitizer
• Differential or single ended input
• DC to>30MHz analog bandwidth
• Full range 150Vpp, 300Vpp, 600Vpp optional

overview

GX2475 is a high-performance, dual differential channel, 14 bit digitizer that provides high dynamic range and excellent SFDR. The differential input of this module combined with its low loss truth makes it an ideal instrument for analyzing high-performance or low-level analog signals. Each channel provides 3 optional low-pass filters, 14 bit, 70MS/s ADC, and 512KB storage. The 50MHz and 70MHz clock dividers provide a common acquisition clock source for both channels.

characteristic

GX2475 provides two differential inputs for low-level measurement in the presence of common mode or noise signals. The input terminal can also be configured as a single ended input. The input impedance can be selected as 10K Ω or 50 Ω. The 50 Ω configuration supports AC or DC coupling. Each input channel can also add offset to the input signal, providing the ability to maximize the dynamic range from A to D.
Both channels provide three, three-level, low-pass, and Butterworth filters, with the ability to bandwidth limit noise signals and minimize aliasing effects. Filters can also bypass the full bandwidth advantage of input amplifiers.

The digitizer has clocks of 10MHz, 50MHz, and 70MHz, and can also be divided by 1-256. Each channel can be independently triggered by external or internal signal sources to begin measurement.

Programming and Software

GX2475 is equipped with a virtual dashboard that includes a 32-bit DLL driver library and documentation. The virtual panel can be used to interactively adjust and control the instrument from the window to display the current settings and measurements of the instrument.
