The Anritsu 68259B is a synthesized signal generator delivering precise RF signal generation across 10 MHz to 26.5 GHz with 1 Hz resolution. Built for demanding RF component testing and system simulation, it combines low phase noise, wide dynamic range, and stable frequency synthesis with analog modulation and sweep capabilities. Output spans -127 dBm to +10 dBm with ±1.0 dB accuracy at +10 dBm. Phase noise reaches -100 dBc/Hz at 1 kHz offset (10 GHz carrier). The instrument supports AM and FM modulation—AM depth to 100%, FM deviation to 200 kHz—plus three sweep modes with selectable trigger sources. Fast frequency switching under 100 ms and frequency stability better than 5×10⁻⁸ per hour enable reliable testing in development and production. Interfaces include Type-N female RF output, GPIB, Ethernet 10/100 Base-T, and USB. Control via Anritsu Signal Generator Control Software or third-party automation tools. Dimensions: 177 mm H × 436 mm W × 416 mm D; 22 kg. Rated 100–240 VAC, 50/60 Hz, 400 VA maximum.
