Description
The Part Number 189182A-02 refers to a high-performance RF Digitizer, specifically the model PXI-5621. This model boasts a 14-bit resolution, ensuring precise and accurate digital representation of analog signals. It is capable of a sample rate of up to 64 MS/s (Mega Samples per second), providing the ability to capture fast-changing signals with high fidelity.
The PXI-5621 comes equipped with a 32MB memory buffer, allowing for significant data storage and processing capabilities directly on the device. Its DC-coupled design ensures a direct pathway for the signal, enhancing the accuracy of measurements. This digitizer features 1 channel, making it suitable for focused, high-quality signal analysis tasks.
Its flexible sample rate range, from 1 kS/s to 64 MS/s, allows users to adjust the sampling to match the requirements of the signal under test, from slow-moving signals to those changing rapidly. The input impedance is set at a 50 Ω nominal value, optimized for RF signal measurements. Additionally, it can handle input signal levels (with dither) up to +8 dBm (±0.794 Vp), accommodating a wide range of signal strengths.
For versatile operation, the PXI-5621 supports various triggering modes, including Software, Digital, and Immediate, offering flexibility for integration into automated testing environments or for manual operation. It requires 1 PXI slot for installation, making it a compact and efficient solution for system integrators and laboratory setups alike. The unit’s dimensions are 3.9 x 6.3 x 0.8 inches, highlighting its compact design.
The External Frequency Reference Input utilizes an SMA female connector, while the External Trigger employs a PFI 1 – SMB male connector, ensuring compatibility with a wide
