Specification

Operating

mode setting

Suspend mode (LED-off)

The power supply is turned off.

Standby mode (LED-white)

It is Standby state, in which the data acquisition is possible.

Data transfer mode

(LED-green, aqua, blue)

In this mode, the driver circuit sends the data to PC.

acquisition

modes

Internal synchronous mode

("INT" mode)

Data is acquired on the basis of the trigger timing generated by application software.

External synchronous mode 1

("EXT.EDGE" mode)

Data is acquired in synchronization with the external trigger signal input from the

BNC connector. In synchronization with an edge of the external trigger signal, data is

accumulated for the set integration time and is then output.

External synchronous mode 2

("EXT.LEVEL" mode)

Data is acquired in synchronization with the external trigger signal input from the BNC

connector. Data is accumulated for a period equal to the pulse width of the external

trigger signal and is then output.

Gain adjustment

The gain value can be varied in the range of “1 to 10” with the step of 1. Default value is

"1".

Offset adjustment

The offset value can be varied in the range of “0 to 1020” with the step of 4. Default

value is "40".

Pulse output signal setting

It is possible to set the timing of the pulse output signal that is output from the “BNC

connector for pulse output” of the driver circuit.
