The Quantum Wave 4000 series of PXIe RF/microwave signal generators provide clean output signals to 12 GHz. These frequency-synthesized continuous-wave (CW) sources are supplied in single-slot 3U PXIe modules. They feature clean signals, with single-sideband (SSB) phase noise of typically -120 dBc/Hz offset 10 kHz from a 1-GHz carrier.
Amplitude can be varied from -10 to +10 dBm across a 20-dV calibrated range with resolution as fine as 0.1-dB steps. The output power level accuracy is typically ±0.3 dB. As an example of the product line, model 4061 is a single-channel synthesizer that operates from 75 MHz to 6 GHz, while model 4062 is a dual-channel synthesizer that covers the same frequency range. For those needing extended frequency coverage, dual-channel model 4122 packs two independent frequency synthesizers into a single-width 3U PXIe module: one spanning 75 to 6 GHz and another that operates to 12 GHz.
