C10508

MODULE APD module C10508 Variable gain and stable detection even at high gains Along with an APD, current-to-voltage conversion circuit, and high-voltage power supply circuit, the C10508 contains a microcontroller to perform temperature compensation based on information from the internal thermosensor. Because temperature coefficients that match the APD temperature characteristics are written in the microprocessor chip, the APD can be operated with a highly stable gain over a wide temperature range even at high gain levels. The gain can be changed by the switch on the board or a command from a PC. Features Applications l Gain fluctuation with temperature: ±5% Max.

Gain setting for each switch number is shown below. 23 9 01 · Changing the gain by command from the PC Setting the rotary switch to "9" enters PC control mode. In this mode, the gain can be set to any integer value from 5 to 400 times.

Default gain is 10. This command sets the gain used with switch "9". Setting range is from 5 to 400. An error occurs if the setting is outside this range. The gain is set to the same value as switch "8" when the power is turned on. This command sets the gain used with switch "8". Setting range is from 5 to 400. An error occurs if the setting is outside this range. The setting is retained even after the power is turned off. · Transmitted data format (ASCII code: 9 characters) 9 # No. 9 8-7 6-3 2-1 8 AA 7 6 5 xxxx Description # Command (2 bytes: US/UG/UW) Data (4 bytes: 0000 ··· 9999) Terminator (2 bytes: carriage return + line feed) 4 3 2 1 · Received data format (ASCII code: 9 characters) 9 or $ * No. 9 8-7 6-3 2-1 8 AA 7 6 5 xxxx Description * (OK) or $ (Error) Command (2 bytes: echo back) Data (4 bytes: 0000 ··· 9999) Terminator (2 bytes: carriage return + line feed) 4 3 2 1 s Sample software Sample software is included on the CD-ROM that comes with the C10508.
