Description
The Part Number 189182A-02 is associated with RF Digitizers, specifically the model PXI-5621. This model is an IF Digitizer, featuring a 32MS capacity and is DC Coupled. The resolution of this device is a high-quality 14-bit, ensuring detailed data capturing. It supports a flexible sampling rate ranging from 1 kS/s to 64 MS/s, with the maximum sample rate reaching up to 64 MS/s.
The input impedance is designed to be 50 Ω nominal, accommodating a wide range of signal types. It can handle a maximum input signal level of +8 dBm (±0.794 Vp), making it robust for various applications. In terms of triggering modes, it offers versatility with options such as Software, Digital, and Immediate modes.
For installation, it requires a single Required PXI Slot. The dimensions of the PXI-5621 are 3.9 x 6.3 x 0.8 inches, making it compact and suitable for integrated setups. For external frequency reference input, it uses an SMA female connector, and for external triggering, it is equipped with PFI 1 – SMB male.
An interesting feature of the PXI-5621 is its dither capability, which ranges from 150 Hz to 4 MH; this can be enabled or disabled through software, providing flexibility in signal processing. The device comes with a 64 MB memory buffer, supporting extensive data collection without immediate offloading. Furthermore, it supports multi-record capturing, enhancing its utility for complex measurement tasks.
Although this product has been announced as obsolete by National Instruments, it remains available for purchase and repairs through Apex Waves, ensuring continued support for users of this sophisticated equipment.
