The Anritsu 68297B is a synthesized signal generator spanning 0.01 GHz to 65.0 GHz, engineered for RF and microwave testing in aerospace, satellite communications, and advanced telecommunications. It delivers maximum output power to +17 dBm with ultra-low phase noise and precise frequency control. The instrument supports analog, step, and manual sweep modes with multiple modulation types, programmable frequency agility up to 1000 non-sequential frequencies, and fast switching times under 15 ms. Dual GPIB ports enable automated testing and remote instrument control.
Technical Specifications

– Key Features
Modulation: Internal AM, FM, and pulse modulation with 7 waveforms including Gaussian noise and user-defined arbitrary waveforms. Pulse modulation supports doublet, triplet, and quadruplet configurations for RADAR blind spot testing. External FM (locked/unlocked) and AM (log/linear) supported. Simultaneous synchronized modulations available.
Sweep Modes: CW or step sweep, analog sweep, manual sweep, and alternate sweep mode (sweeps between two ranges with independent power levels per range). Step sweep configurable from 1 to 10,000 steps with dwell times from 1 ms to 99 seconds. Analog sweep width 1 kHz to full range; sweep time 30 ms to 99 seconds with ±30 MHz accuracy (or ±2 MHz widths for sweep speeds ≤50 MHz/ms).
Frequency Agility: Up to 1,000 non-sequential frequencies storable and addressable as phase-locked step sweep via GPIB control.
– Compatibility & Integration
Dual GPIB ports standard. Remote interface options enable automated test system integration and programmable control of all instrument functions.
