Description
The PXI-5621, bearing the part number 189182A-02, is a high-precision signal digitizer known for its exceptional performance in a wide range of applications. This device boasts a 14-bit resolution, ensuring accurate and detailed signal representation.
One of its most significant features is the versatile sample rate range, which extends from 1 kS/s to 64 MS/s, with the maximum sampling rate reaching up to 64 MS/s. This allows for high-speed data acquisition, making the PXI-5621 suitable for various demanding applications.
The PXI-5621 features DC input coupling and supports a single channel configuration. It is designed with a 50 Ω nominal input impedance, and it can handle a maximum input signal level of +8 dBm (±0.794 Vp), providing flexibility in connecting different types of signal sources.
It offers multiple triggering modes, including Software, Digital, and Immediate, thus enabling users to configure the start of acquisition according to their specific requirements. Furthermore, it requires only one PXI slot for installation, making it a compact and efficient choice for systems with limited space.
The dimensions of the PXI-5621 are 3.9 x 6.3 x 0.8 inches, and it includes an external frequency reference input through an SMA female connector, as well as an external trigger via PFI 1 – SMB male. This ensures easy integration and synchronization with other devices.
Additionally, the PXI-5621 is equipped with a 64 MB memory buffer, supporting multi-record capturing mode. This feature is particularly useful for applications requiring the analysis of multiple signal events over time. The device also offers a dither function, ranging from 150 Hz to 4 MHz, which can be enabled or disabled via software, further enhancing its flexibility
