2510型設備基于給定的溫度傳感器TEC制冷片進(jìn)行編程，并設置單點(diǎn)溫度。在控制器將激光二極管模組穩定到目標溫度之前，首先對TEC的AC電阻進(jìn)行測量和顯示。 如下是一個(gè)利用Visual Basic和吉時(shí)利488 GPIB卡控制2510-AT的實(shí)例。 ‘Reset Instruments send(kth2510, “*rst”, status) ‘reset TEC controller ‘Setup Peltier Current Limit send(kth2510, “:sens:curr:prot:lev 1.0”, status) ‘Setup Temperature Sensor send(kth2510, “:sens:temp:tran ther”, status) ‘use thermistor send(kth2510, “:sens:temp:curr:auto on”, status) ‘auto sensor current level send(kth2510, “:sens:temp:ther:range 1e4”, status) ‘10K ohm Ther. send(kth2510, “:sour:temp:spo 25.0”, status) ‘set temp. to 25C, Read Peltier AC Ohms send(kth2510, “  utp on”, status) ‘turn on outputsend(kth2510, “:meas:res:ac?”, status) ‘measure AC ohms enter(strData, 100, intLength, kth2510, status) ‘enter reading txtTECRes.Text = strData ‘display on screen ‘Begin controller Laser Diode Temperature send(kth2510, “ utp on”, status)了解吉時(shí)利2602型源表更多信息，請戳http://www.keithley.com.cn/products/localizedproducts/currentvoltage/2602/ 想與吉時(shí)利測試測量專(zhuān)家互動(dòng)？想有更多學(xué)習資源？可登錄吉時(shí)利官方網(wǎng)站http://www.keithley.com.cn/ |
