在……上SCXI-1531(零件號:777966-31)國家文書模塊，當加速度計的兩個信號線都浮地時，用戶可以參考打開的地來配置該模型的通道。這種模式可防止典型模式電位通過放大器的輸入端累積，從而成為噪聲源。模塊的基本輸出速率不得小于最高通道傳輸容量設置的10倍。在極其嘈雜的情況下，相當高的輸出速率可能是最基本的。例如，如果用戶使用三個信道，并且它們的信道傳輸速度是2.5、2.5和5.0 kHz，則基本掃描速率是50 kHz。

還包括多路復用模式，通常用于執(zhí)行濾波操作SCXI-1531。在多路復用掃描操作之前，SCXI機箱會被修改為一個模塊過濾器列表，該列表控制哪個模塊在掃描期間將其輸出發(fā)送到SCXIbus。用戶可以影響此列表掃描，以任何順序檢查機箱中的模塊，列表中每個模塊條目的通道數(shù)量可選，每個機箱最多512個通道。用戶還可以任意過濾上的頻道SCXI-1531。信道可以按任何順序排列，并且信道可以在單次掃描中出現(xiàn)多次。當執(zhí)行多次掃描時，模塊的列表指針會繞回并從掃描列表中的第一個通道開始檢查。

On the SCXI-1531 (Part Number: 777966-31) National Instruments module, when both signal lines of the accelerometer are floating to ground, the user can configure this model’s channel with reference to ground switched on. This mode prevents a typical mode potential from accumulating through the input of the amplifier that can be a source of noise. The base output rate for the module must not be less than 10 times the highest channel transmission capacity setting. In extremely noisy situations, considerably higher output rates might be fundamental. For instance, if the user is utilizing three channels and their channel transfer speeds are 2.5, 2.5, and 5.0 kHz, the base scan rate is 50 kHz.

Multiplexed mode is also included and is regularly utilized for performing filtering operations with the SCXI-1531. Instantly preceding a multiplexed scanning operation, the SCXI chassis is modified with a module filter list that controls which module sends its output to the SCXIbus during a scan. The user can influence this list scan to examine the modules in the chassis in any order, with an optional number of channels for every module entry in the list, limited to a total of 512 channels for every chassis. The user can also arbitrarily filter the channels on the SCXI-1531. The channels can be in any order and the channels can happen in multiple times in a single scan. When performing multiple scans, the list pointer of the module consequently wraps around and begins examining with the first channel in the scan list.
