National Instruments 778284-01 PXI Vector Signal Analyzer
The National Instruments 778284-01 (or PXI-5660) is a PXI Vector Signal Analyzer that is designed for high-throughput RF acquisition and measurements. Covering a frequency range from 9 kHz to 2.7 GHz, this analyzer offers a real-time bandwidth of 20 MHz. It supports resolution bandwidths from less than 1 Hz to 10 MHz that provides flexibility for various applications. The analyzer's selectivity features include a 60 dB to 3 dB ratio, with maximum values of 2.5 for Flat Top and 4.1 for the 7-term Blackman-Harris window.
The NI 778284-01 module is equipped with an NI 5620 digitizer and an NI 5600 downconverter. The module offers hardware tuning resolutions of 0.015 Hz and a minimum of 1 MHz, respectively. The downconverter tuning speed is highly accurate, with a settling time of 10 ms for 1% of step size, 20 ms for 0.01%, and 30 ms for 0.0001%. The overall dimensions of the unit are 21.6 cm × 6.0 cm × 13.0 cm (NI 5600) and 21.6 cm × 2.0 cm × 13.0 cm (NI 5620). The nominal impedance of the module is 50 Ω with AC input coupling. It can handle a maximum DC input voltage of ±25 VDC. The Voltage Standing Wave Ratio (VSWR) varies based on attenuation and frequency. It ranges from a maximum of 1.3:1 for 9 kHz to 2.2 GHz with attenuation enabled, to 2.5:1 for 2.2 GHz to 2.7 GHz with attenuation disabled. LO emission from the RF input is kept below -87 dBm.
The NI 778284-01 handles amplitude ranges from below the averaged noise level to +30 dBm. The RF input attenuateion can be adjusted from 0 dB to 50 dB in 10 dB steps. The device is powered by +3.3VDC, +5VDC, +12 VDC, and -12VDC voltage ranges. It can operate at a maximum altitude of 2,000 meters with a pollution degree of 2. This analyzer operates in ambient temperatures from 0 °C to 50 °C and relative humidity from 10% to 90%. The module weights 1,165 g and comes in a 3U design. With a high-stability OCXO timebase and 32 MB onboard memory, the 778284-01 is optimized for engineers requiring rapid data streaming and real-time signal processing. Its versatile specifications make it suitable for applications in software-defined radio, spectral monitoring, and other high-precision RF measurement tasks.
