Pan-China Hengxing releases high-precision data acquisition card designed for sound and vibration applications

21ic News Beijing Fanhua Hengxing Technology Co., Ltd. (abbreviation: Fanhua Hengxing) recently released the PS PXI-3346 2-input/2-output dynamic signal acquisition card. The PS PXI-3346 is a high-precision data acquisition card designed for sound and vibration applications. It provides two 24-bit analog inputs and two 24-bit analog outputs. It is ideal for excitation applications including sound and structural testing.

PS PXI-3346 analog input channel sampling rate of up to 204.8KSPS, each channel integrated independent 4mA/10mA IEPE excitation source, can achieve accelerometer sensor and microphone related signal conditioning. The user can select two input terminals for differential input or pseudo differential input according to different signals to be tested. PS PXI-3346 supports AC/DC two coupling modes, which can be independently configured by software. A low-pass filter with variable on-board cutoff frequency reduces high frequency noise and reduces frequency aliasing. At the same time, the PS PXI-3346 provides a variable anti-image filter that supports low frequency difference compensation points.

The PS PXI-3346 has a flexible channel configuration for an excitation-like application test system that requires multiple simultaneous inputs and multiple simultaneous outputs. It enables simultaneous operation between multiple PS PXI-3346s in a PXI chassis, as well as multiple chassis configurations. Synchronous operation of the PS PXI-3346, common applications include audio amplifier and production instrument testing, shaker control, vibration analysis, and machine condition detection.

In addition, for high-channel dynamic signal acquisition applications, the PS PXI-3346 with PS PXI-3342 (8-channel dynamic signal acquisition card) can expand the required analog input channels for applications such as dynamic structure testing, sound/vibration testing, etc. Dynamic signal acquisition applications for channel counts.

Why we recommend IPhone 6S Battery With TI IC (Texas Instruments ) rather than ZY/ZW?

1. TI IC is original method for iPhone battery .

2. Charging more faster, less fever heat to save battery life.

3. Accurate battery power monitorin

4. Keep stable performance and controlable temperture

5. The battery with TI IC more safe, charge more faster, lasts longer life.   


We are iPhone Battery manufacturer can supply Original TI IC for customer needs,iPhone 6S 0 cycle Battery with TI IC have 100% compatiable with iOS lastest system. iPhone 6S Battery TI IC is more stable performance than other IC,that is why we high recommend iPhone 6S 0 cycle battery TI IC.
