Introduction 3

General Specifications

Connectors 5 BNC-type, one 10-pin header

Operating Temperature 0°C to 40°C

Storage Temperature -20°C to 80°C

Humidity 5% to 85%, non-condensing

Power Consumption +5 V 2.5 A (maximum)

With a single channel enabled, the maximum sampling rate is 20 MHz. With

two channels enabled, the 20 MHz sampling rate may only be reached when

the number of samples accessed for each channel is smaller than 16K. With

four channels enabled, the 20 MHz sampling rate may only be reached when

the number of samples accessed for each channel is smaller than 8K. Refer

to section 5.5 for more information on sampling rates and data length limita-

tions.
