Description
The NI PXI-5695 is a high-performance, 8 GHz programmable RF attenuator designed for general-purpose RF signal conditioning. This device is part of the General Purpose RF Sig Conditioning category and is identified by the part numbers 195809C-01L / 781036-01. The model PXI-5695 features a versatile attenuation range of 70 dB, distributed across two channels. This includes one programmable and one fixed attenuation path, allowing for flexible signal manipulation.
The PXI-5695 operates over a broad frequency range from 50 MHz to 8.0 GHz, catering to a wide spectrum of RF applications. It boasts an attenuation resolution of +0.5 dB for channel 1, ensuring precise control over signal levels. Additionally, the level calibration accuracy is rated at ±0.7 dB for channel 1, highlighting the device’s reliability and consistency in performance.
The attenuation settling time is impressively quick at +4 µs for channel 1, which facilitates rapid adjustments and minimal delay in signal processing. The PXI-5695 is also capable of handling significant power levels, with a maximum input power (operation) of +27 dBm (5 Vrms, 7 Vpk) and a maximum reverse power of +26 dBm, ensuring durability and robustness in high-power environments.
Connectivity is facilitated through SMA female connectors, with an impedance of 50 Ω, ensuring compatibility with standard RF equipment and systems. The device’s form factor is a compact, one-slot, 3U PXI module, measuring 21.6 cm × 2.0 cm × 13.0 cm, making it an efficient use of space within any PXI chassis.
