The Programmed Test Sources PTS 3200 DJ010 is a high-performance frequency synthesizer delivering precise signal generation across 1 MHz to 3200 MHz with 1 Hz resolution. Built on direct synthesis architecture, it provides coherent frequency control locked to internal or external frequency standards while maintaining exceptional phase noise performance and spectral purity. The instrument generates stable sine wave outputs with adjustable levels from +3 dBm to +13 dBm into 50 Ω, flatness within ±0.7 dB, and phase-continuous switching in 3–20 µs depending on digit configuration.
