这PXI-6608(零件号:777937-01)计数器/定时器模块所产生国家文书是的增强版本PXI-6602，并增加了一个高稳定度的时钟，称为恒温晶体振荡器(OCXO)。该模块有8个递增/递减计数器/定时器，32位分辨率，所需功率为1 A至2.5 A，300 mV施密特触发器迟滞，每个测量和源频率为80 MHz，输入阻抗为25kω至500kω，输出阻抗为75ω。建议在0°C至55°C的温度范围内预热五分钟，以达到这些规格。
的一个有价值的功能PXI国家仪器公司-6608模块被称为防止重复计数或同步计数模式。这个特性保证了计数器在应用程序中产生准确的信息，这些应用程序是一个缓慢的或非周期性的外部源。重复计数预防仅与缓冲计数器应用相关，例如测量频率或周期。在缓冲计数器应用期间，计数器应保存外部源在Gate信号上升沿之间的脉冲次数。
大西洋上的OCXOPXI-6608计数器/定时器模块确定用户时间测量和脉冲产生的精确度。OCXO可以用作计数器的门或源。第三种选择是利用OCXO作为PXI底板时钟。锁相到PXI底板时钟的任何模块将获得与计数器/定时器模块相同的时钟稳定性。公共参考时钟信号可用于协调测量或控制系统中的多个模块。
这PXI-6608使用NIDAQmx驱动软件运行，该软件与软件包/应用程序开发环境(ade)兼容，如LabVIEW、LabWindows/CVI或Measurement Studio。
NI设备的物理尺寸为16.0 x 10.0厘米。它建议操作和储存温度范围分别为0°C至55°C和–20°C至70°C，非冷凝操作和储存湿度范围分别为0%至90%和5%至95%。
PXI-6608
The PXI-6608 (Part Number: 777937-01) Counter/Timer Module produced by National Instruments is an enhanced version of the PXI-6602, with the addition of a high-stability clock, which is known as an oven-controlled crystal oscillator (OCXO). This module has eight up/down counters/timers, 32 bits resolution, 1 A to 2.5 A power required, 300 mV Schmitt triggers hysteresis, measure and source frequencies of 80 MHz each, 25 kΩ to 500 kΩ input impedance, and 75 Ω output impedance. A five minute warm-up time along with a temperature ranging from 0 °C to 55 °C is recommended to achieve these specifications.
A valuable feature of the National Instruments PXI-6608 module is known as duplicate count prevention or synchronous counting mode. This feature guarantees that a counter yields accurate information in applications that are an unhurried or non-periodic external source. Duplicate count prevention is only pertinent to buffered counter applications, such as measuring frequency or period. During buffered counter applications, the counter should save the number of times an external source pulses between rising edges on the Gate signal.
The OCXO on the PXI-6608 Counter/Timer Module determines the preciseness of the user’s time measurement and pulse generation. The OCXO can be operated as a GATE or SOURCE for a counter. A third option is to utilize the OCXO as the PXI backplane clock. Any modules that are phase locked to the PXI backplane clock will obtain equivalent clock steadiness as the Counter/Timer Module. The common reference clock signal can be utilized to coordinate numerous modules in a measurement or control system.
The PXI-6608 is run using the NIDAQmx driver software which is compatible with software packages/application development environments (ADEs) such as LabVIEW, LabWindows/CVI, or Measurement Studio.
The NI device measures 16.0 x 10.0 cm in physical dimensions. It has recommended operating and storage temperature ranges of 0 °C to 55 °C and –20 °C to 70 °C respectively, and non-condensing operating and storage humidity ranges of 0% to 90% and 5% to 95% respectively.
