Clock generators are now available in the modular PXI format, for applications through 4.1 GHz with low phase noise. Model BI401 is a frequency-synthesized square-wave clock generator module from Brilliant Instruments that fits within a single PXI instrument slot. It is available in two basic models, with frequency ranges of 1 μHz to 2.1 GHz (model BI401-2G) and 1 μHz to 4.1 GHz (model BI401-4G), with both models capable of producing DC outputs. The phase noise is only -102 dBc/Hz offset 10 kHz from a 1-GHz carrier with outstanding performance in the time domain, with less than 0.5 ps jitter. The square-wave synthesizer achieves frequency switching speed of better than 250 μs.

Model BI401 is a synthesized square-wave clock generator that fits within a single 32-b PXI slot.

The model BI401 square-wave synthesizer provides single-ended and differential output ports. The single-ended port is capable of 6-V peak-to-peak output amplitude; the differential port offers 1-V peak-to-peak maximum amplitude with 65-ps risetime. The PXI frequency synthesizers include a standard timebase of a 2-ppm temperature-compensated crystal oscillator (TCXO), with an option for an oven-controlled-crystal-oscillator (OCXO) timebase with 0.02-ppm accuracy.

These frequency synthesizers incorporate Practically Perfect frequency resolution to provide 20 digits of frequency resolution with less than 1 ps of accumulated drift per year. At 4 GHz, the frequency resolution is 0.1 nHz. The frequency synthesizers, which are ideal for a variety of applications in both test and measurement and radar systems, consume only 14 W power. They are shipped with operating software that is compatible with MS Windows and Linux operating systems and written in plain C++ language for ease of porting to other software environments. Each model BI401 frequency synthesizer is supplied in a 3U PXI module measuring 5.1 × 7.3 in. and weighing 6.4 oz. (180 g). They each fit a single 32-b PXI slot.
