National Instruments 779670-00 RF Signal Generator
The part number 779670-00 from National Instruments is the identifying part number for the PXI-5650 RF Signal Generator. This generator has a frequency range of 500 kHz to 1.3 GHz with a resolution of less than 3 Hz. The internal reference clock maintains an initial accuracy of ±3 ppm, with a maximum temperature drift of ±1 ppm between 15 degrees Celsius to 35 degrees Celsius, and an aging rate of ±5 ppm per year.
The 779670-00 has fast frequency settling times, with a narrow loop bandwidth achieving a median settling time of 1 ms and a maximum of 5 ms for 0.01 ppm accuracy. In wide loop bandwidth mode, the settling time improves further, achieving a median of 0.2 ms and a maximum of 0.7 ms for 1.0 ppm accuracy. It has spectral purity with single sideband (SSB) phase noise at 10 kHz offset typically measured at -111 dBc/Hz for 100 MHz, -107 dBc/Hz for 500 MHz, and -105 dBc/Hz for 1 GHz. The device's residual FM at 1 GHz (300 Hz to 3 kHz, RMS) is less than 0.8 Hz RMS, and its jitter at 622 MHz with 1 kHz to 5 MHz jitter bandwidth is typically less than 200 fs RMS.
This RF generator provides an amplitude range from -90 dBm to 10 dBm, depending on the frequency, with a resolution of less than 0.1 dB. The power level accuracy within the temperature range of 15 degrees Celsius to 35 degrees Celsius is ±0.75 dB for output powers greater than -40 dBm and ±1.8 dB for lower power levels. The 779670-00 also features a signal-to-noise ratio (SNR) of -140 dBc/Hz or better for output powers of 0 dBm or higher.
The 779670-00 is a 3U PXI module, occupying one slot with dimensions of 2.0 cm × 13.0 cm × 21.6 cm (0.8 in. × 5.1 in. × 8.5 in.) and a weight of 415 g (14.6 oz). It operates within an ambient temperature range of 0 °C to 55 °C and a relative humidity range of 10% to 90%, noncondensing. The module can withstand storage temperatures from -40 °C to 70 °C and relative humidity levels from 5% to 95%, noncondensing.
