Introducing the new SG380 Series RF Signal Generators — finally, high performance, affordable RF sources.
The SG380 Series RF Signal Generators use a unique, innovative architecture (Rational Approximation Frequency Synthesis) to deliver ultra-high frequency resolution (1 µHz), excellent phase noise, and versatile modulation capabilities (AM, FM, ØM, pulse modulation and sweeps) at a fraction of the cost of competing designs.

The standard models produce sine waves from DC to 2.025 GHz (SG382), 4.05 GHz (SG384) and 6.075 GHz (SG386). There is an optional frequency doubler (Opt. 02) that extends the frequency range of the SG384 and SG386 to 8.10 GHz.
Low-jitter differential clock outputs (Opt. 01) are available, and an external I/Q modulation input (Opt. 03) is also offered. For demanding applications, the SG380 Series can be ordered with a rubidium timebase (Opt. 04).

Specifications :

• DC to 2 GHz, 4 GHz or 6 GHz
• 1 µHz resolution
• AM, FM, ØM, PM and sweeps
• OCXO timebase (std.)
• -116 dBc/Hz SSB phase noise (20 kHz offset, f = 1 GHz)
• Rubidium timebase (opt.)
• Square wave clock outputs (opt.)
• Analog I/Q inputs (opt.)

The delay resolution on all channels is 5 ps, and the channel-to-channel jitter is less than 50 ps.Front-panel BNC outputs deliver TTL, ECL, NIM or variable level (-3 to +4 V) pulses into 50 W or high impedance loads. The high accuracy, low jitter, and wide delay range make the DG535 ideal for laser timing systems, automated testing, and precision pulse applications.
