Description
The PXI-5621 is an RF digitizer that comes with a part number 189182C-02. This device falls under the category of RF Digitizers and is designed to offer high-performance digitization. It features a 14-bit resolution, ensuring precise measurement capabilities. The PXI-5621 is capable of sampling rates of up to 64 MS/s, making it suitable for a wide range of high-speed signal processing applications.
It comes equipped with a 64 MB memory buffer, which allows for the storage and manipulation of large amounts of data. This digitizer utilizes a DC coupling type, providing flexibility in various signal acquisition scenarios. With one input channel, it offers a focused approach to signal capture, and the input impedance is rated at 50 Ω nominal, making it compatible with a wide range of signal sources.
The input signal level can reach up to +8 dBm (±0.794 Vp), allowing the device to handle moderately powerful signals without distortion. The PXI-5621 supports multiple triggering modes including software, digital, and immediate, offering versatility in signal acquisition and analysis. Additionally, it features an external frequency reference input through an SMA female connector and an external trigger via PFI 1 – SMB male, enhancing its adaptability in complex setups.
One of the notable functionalities of the PXI-5621 is its dithering capability, which can be enabled or disabled through software. This feature is particularly useful in improving the accuracy of digital signal processing by reducing quantization error. It’s important to note that the PXI-5621 has been announced as obsolete by National Instruments, however, it remains available for purchase and repair through Apex Waves, ensuring continued support for users of this advanced RF digitizer.
