The National Instruments PXI-5691 is a 2-channel, single-slot 3U PXI programmable RF amplifier with a frequency range up to 8 GHz, offering both programmable and fixed gain paths, compatible with LabVIEW and other
The National Instruments PXI-5691 with Part Number 781035-01 is a versatile 2-Channel, Programmable PXI RF Amplifier capable of reaching up to 8 GHz in frequency. It is designed as a single-slot 3U PXI module that houses one programmable and one fixed gain path, allowing for flexible signal amplification in a compact form factor.
Channel 0 (CH 0) boasts impressive specifications, including ±0.9 dB level calibration accuracy and the ability to handle up to +30 dBm of input power, +20 dBm of reverse power without damage, and can output up to +25 dBm, with a typical ±10 V DC voltage at the input. Channel 1 (CH 1) complements this with a +31.5 dB gain range, a fine gain step size of +0.5 dB, and a swift +4 µs maximum level settling time, maintaining the same ±0.9 dB level calibration accuracy and +30 dBm input power capability.
Despite its advanced features, the PXI-5691 maintains a moderate maximum power consumption profile, requiring 2.1 W at 3.3 Vdc, 6.9 W at 5 Vdc, 2.9 W at 12 Vdc, and 0.34 W at -12 Vdc. This amplifier is compatible with a range of driver software, including LabVIEW, C, and LabWindows/CVI, and can be configured using the Measurement & Automation Explorer (MAX) tool, making it a convenient and adaptable choice for a variety of RF signal amplification needs.
