National Instruments SCXI-FRQ8 Frequency Counter

The National Instruments SCXI-FRQ8 is an advanced frequency counter with eight channels of precise measurement and counting capabilities. With a maximum sampling rate of 333 kS/s and the ability to handle TTL-level inputs up to 20 MHz, this module is ideal for high-speed event counting and frequency measurement applications.

Each channel's gain and filter settings on the SCXI-FRQ8 can be programmed to fit unique measurement needs, enabling customized signal conditioning. To further improve the module's adaptability in managing a variety of signal circumstances, each channel also offers programmable threshold and hysteresis settings. All eight inputs can be handled simultaneously thanks to this modular construction, which can be managed by software to guarantee precise and coordinated data collection.

The SCXIbus digital serial protocol enables dependable and effective data transfer by facilitating data communication with the SCXI-FRQ8. Users may need to confirm driver compatibility for more recent operating systems or settings, as the module comes with LabVIEW drivers that are compatible with Windows NT/95/3.1.

For sophisticated data collection systems, the SCXI-FRQ8 is highly useful because synchronization of buffered counter/timer operations, analog inputs, and digital I/O is important. Combining analog measurements from car components with digital data from sensors like crankshaft encoders is a common requirement in automotive testing, for instance. Correlating these data streams to help evaluate vehicle performance under various conditions, the SCXI-FRQ8 offers important insights into system behavior and efficiency. The frequency counter can track the relationship between location, torque, and time when inserting screw caps in manufacturing operations like the production of bottles.

Unmatched timing flexibility is possible when combining the sophisticated timing and triggering capabilities of the SCXI-FRQ8 with the E Series DAQ boards from National Instruments. As a result, correlated data curves like torque versus time or position vs temperature can be created. This permits concurrent mixed signal acquisition.
