The Anritsu 68069B is a synthesized continuous-wave (CW) signal source covering 0.01 GHz to 40.0 GHz with microprocessor-based frequency control and high-resolution phase-lock capability. It delivers output power from –125 dBm to +13 dBm (extending to +17 dBm across select frequency bands) with 0.01 dB resolution and 2 dB output accuracy. Ultra-low SSB phase noise of –100 dBc at 10 kHz offset from 10 GHz enables precision local oscillator and test applications. The instrument generates discrete CW frequencies with 1 kHz minimum step size, optionally 0.1 Hz with Option 11, and supports broad and narrow band sweep modes with up to 10,000 steps, variable dwell times from 1 ms to 99 seconds, and step switching under 15 ms + 1 ms/GHz or 40 ms maximum. Spurious signals remain typically –40 dBc for harmonics and non-harmonics. Internal modulation includes AM, FM, phase modulation, and pulse modulation for radar testing; user-downloadable complex modulation and frequency agility up to 1000 non-sequential frequencies under GPIB control are supported. All functions are accessible via front panel or IEEE-488 GPIB remote control. Harmonic output and alternate sweep modes provide flexible signal generation for R&D, ATE, and frequency conversion applications.
