美國Keithley 3720 Dual 1X30 Multiplex Card 多路傳輸卡

吉時利3720 雙1 x30多路卡提供了兩個獨立的記憶庫，1 x30兩極多路復用器。吉時利3720是理想的通用轉換器,包括溫度測量。這兩個記憶庫可以自動被連接到系列3700A主機背板和可選的數字萬用表，通過模擬底板和連接繼電器。此連接允許主機重新配置卡一個1 x60兩極多路復用器或啟用卡片卡片轉換器擴張更大的配置。吉時利3720的其他特性包括重新配置的能力協調四端操作額外測量的靈活性。此外,吉時利3720支持熱電偶溫度測量時使用的吉時利第3720(螺絲接線端)附件提供自動冷端補償(CJC)。吉時利3720使用了兩個78插針，公sub連接器為中共信號連接。螺絲接線端或自動CJC,使用可拆卸的吉時利3720附件。

The Keithley 3720 Dual 1X30 Multiplex Card offers two independent banks of 1x30 two-pole multiplexers. The Keithley 3720 is ideal for general purpose switching, including temperature measurements. The two banks can automatically be connected to the Series 3700A mainframe backplane and optional digital Multimeter through the analog backplane connection relays. This connection allows the mainframe to reconfigure the card to a single 1x60 two-pole multiplexer or to enable card-to-card expansion for even larger configurations. Other features of the Keithley 3720 include its ability to be reconfigured to coordinated four-pole operation for additional measurement flexibility. Furthermore, the Keithley 3720 supports thermocouple-type temperature measurements when used with the Keithley 3720-ST (screw terminal) accessory providing automatic cold junction compensation (CJC). The Keithley 3720 uses two 78-pin male D-sub connectors for signal connections. For screw terminal or automatic CJC, use the detachable Keithley 3720-ST accessory.
