3. Features

Maximum conversion speed is 10MSPS (100nsec), with
simultaneous sampling of 4channels at a time
The maximum conversion speed is 10MSPS (100nsec) and 4channels can be sampled simultaneously.
The range for each channel can be set independently by software to match the level of the input signal source.
(Input range :
± 10V, ± 5V, ± 2.5V, ± 1.25V or 0 - +10V, 0 - +5V, 0 - +2.5V)
Also features digital inputs and outputs (four LVTTL level input and output ports respectively).
(requires the optional DT-E3 cable)

Sampling can be controlled by software, conversion
data comparison, external trigger, event controller
output, and similar start and stop conditions
Sampling can be setup to be started and stopped by software, conversion data comparison, external trigger, or event controller output.
Control of sampling start and stop is completely independent and a separate setting is provided for each. It is also possible to specify
that sampling stop after a specified number of samples.
The conversion data comparison function can perform level, in-range, and out-of-range comparisons on the conversion data.

Incorporates a synchronization control connector for
synchronized operation
A synchronization control connector is provided for synchronized control of up to 16 boards. This means the number of channels can
be increased simply by adding boards. It is also easy to
synchronize operation with other CONTEC boards that have a synchronization
control connector.

Bus master transfer function allows continuous data
acquisition at high speed for a long period
The bus master transfer function allows continuous data acquisition to be performed at high speed for a long period. Furthermore, this
function can transfer large volumes of data between the board and the PC.

BNC connector used for analog input pin
The BNC connector used for the analog input has a characteristic impedance of 50 Ω and is of a type commonly used for high speed
analog signals. This makes it easy to connect to other devices with a BNC connector.

Termination resistor selection function
A 50 Ω termination resistor can be set to minimize the distortion caused by the reflection of high-speed input signals. The input range
cannot be set to ± 10V or 0 to +10V when the termination resistor is used.

Digital filter function included to prevent misdetection
due to chattering on external input signals
A digital filter is included to prevent misdetection due to chattering on the digital input signals.
