Overview斯坦福StanfordResearchSystems發布CTC100低溫溫度控制器—可以以毫開爾文分辨率（mk）監測和控制溫度
Sensor Inputs
CTC100提供四個溫度輸入，可以支持RTD、熱敏電阻和二極管。每個溫度輸入通道都有自己的24位ADC，具有11個輸入范圍，并配有自己獨立的激勵電流源。
內置各種傳感器的標準校準曲線，每個傳感器最多可輸入400點的自定義校準曲線。每個傳感器輸入都有高電平和低電平或變化率警報。傳感器輸入可以進行低通濾波以減少噪聲，和/或與另一個通道進行差分。
CTC100有兩個加熱器輸出，每個輸出可向25? 加熱。此外，在外部放大器的幫助下，可以使用四個模擬電壓I/O通道來驅動加熱器。
PID Feedback Control
CTC100最多可提供六個反饋控制回路，通過不斷調整加熱器功率，可以對每個加熱器輸出進行精確的溫度控制。CTC100的任何通道都可以被選擇作為每個反饋回路的輸入。反饋時間常數可以在200毫秒和10小時之間調整。
每個通道最多可以存儲十組PID參數。設定點可以以固定的速率傾斜。
Analog and Digital I/Os
CTC100配有四個通用±10 V電壓I/O通道，由24位ADC讀取。它還有八個數字I/O通道，可以與用戶程序進行交互。
四個5A繼電器可用于過程控制。三個虛擬通道不連接到任何物理輸入，允許顯示、繪制和記錄計算值（如兩個通道之間的差，或用戶程序計算的值）。
Numeric and Graphical Display
The CTC100's color LCD display can show any combination of temperature measurements and heater outputs on graphs or numeric displays. Up to eight channels can be plotted either on a single graph with a common Y axis, or on separate graphs with independent Y axis. Touchscreen operation makes the instrument versatile and easy to use.
CTC100的彩色液晶顯示器可以在圖形或數字顯示器上顯示溫度測量值和加熱器輸出的任何組合。最多可以在具有公共Y軸的單個圖形上繪制八個通道，也可以在具有獨立Y軸的單獨圖形上繪制。觸摸屏操作使儀器用途廣泛且易于使用。
Data Logging
Up to 1 million readings per channel can be logged to the CTC100's internal memory.
Data logged to USB devices can be transferred to a computer by plugging the USB device into a PC. A Windows applications can be downloaded from SRS website to graph CTC100 log files.通過將USB設備插入PC，可以將記錄到USB設備的數據傳輸到計算機。可以從SRS網站下載Windows應用程序來繪制CTC100日志文件。
Computer Communications
Each of the CTC100's front-panel controls has a corresponding text commａnd that can be sent over USB, Ethernet, and either
CTC100的每個前面板控件都有一個相應的文本命令，可以通過USB、以太網和RS-232或可選的GPIB(另行選購)接口發送。
When the USB interface is used, the CTC100 appears on the computer as a standard COM port and can be controlled by any software that is compatible with an
當使用USB接口時，CTC100作為標準COM端口出現在計算機上，并且可以由任何與RS-232端口兼容的軟件控制。
User Programs
User programs (macros), consisting of one or more remote commands, can be uploaded to the CTC100. This is done by either sending them through one of the communications ports or by saving them as text files on a USB memory device and then plugging the device into the CTC100. Program macros can also be entered and edited from the front panel.
由一個或多個遠程命令組成的用戶程序（宏）可以上傳到CTC100。這可以通過其中一個通信端口發送，或者將它們保存為USB存儲設備上的文本文件，然后將設備插入CTC100來完成。程序宏也可以從前面板輸入和編輯。
