Description
The Part Number 189182A-01 corresponds to a high-performance RF Digitizer, specifically the model PXI-5621. This device is designed with a 14-Bit resolution, ensuring precise digital representation of the analog input signal. It comes equipped with a 32MB memory buffer, enabling it to handle large amounts of data efficiently.
The PXI-5621 boasts an impressive sampling rate of 64MS/s (Mega Samples per second), providing the capability to capture fast-changing signals accurately. Its input coupling is of DC type, ensuring that both AC and DC components of the input signal are accurately digitized.
With one input channel, this digitizer is designed for high-precision single-channel measurements. The sample rate range is quite flexible, ranging from 1 kS/s to 64 MS/s, allowing for versatile application across various signal analysis tasks. Furthermore, the input impedance is set at 50 Ω nominal, which is standard for RF and high-speed digital circuits, ensuring compatibility with a wide range of signal sources.
The input signal level can reach up to +8 dBm (±0.794 Vp) with dither enabled, providing an enhanced signal-to-noise ratio for improved measurement accuracy. The device supports multiple triggering modes, including Software, Digital, and Immediate, offering flexibility in signal acquisition and analysis.
Dimension-wise, the PXI-5621 measures 3.9 x 6.3 x 0.8 inches, making it compact enough for integration into various test and measurement setups. It also features an external frequency reference input via an SMA female connector, and an external trigger through PFI 1 – SMB male, enhancing its capability for synchronized measurements in complex systems.
The device also allows for dither between 150 Hz
