The Anritsu 68345B is a synthesized sweep/signal generator delivering stable, precise RF and microwave signals across 0.5 to 20 GHz. Built for production testing, system validation, and R&D environments, it combines ultra-low phase noise with flexible modulation and sweep capabilities. Remote programming and GPIB control enable integration into automated test workflows.
Technical Specifications
Frequency Range: 0.5 to 20 GHz
Output Power: +13 dBm maximum; −125 dBm minimum
Phase Noise: −100 dBc/Hz SSB at 10 kHz offset from 10 GHz
Sweep Capability: Synthesized step sweep with 1 to 10,000 steps. Step size ranges from 1 kHz (0.1 Hz with Option 11) to full instrument range. Dwell time per step: 1 ms to 99 seconds. Frequency switching time: <15 ms + 1 ms/GHz step size or <40 ms maximum (typical). Manual sweep mode provides phase-locked frequency adjustment between limits. Alternate sweep mode enables switching between two independent sweep ranges with different power levels. Sweep width independently selectable from 1 kHz (0.1 Hz with Option 11) to full range.
