Product Features
✅ Ultra-Wide Frequency Coverage with High Resolution
The TG20A covers 9 kHz to 21 GHz with a fine frequency resolution of 0.001 Hz, enabling precise signal generation for high-frequency applications such as millimeter-wave communications, radar simulation, and satellite testing.
✅ High Dynamic Output Power Range
With an output power range from -120 dBm to +17 dBm, the TG20A supports both low-noise receiver testing and high-power stimulus scenarios, eliminating the need for external amplifiers or attenuators in most setups.
✅ Exceptional Signal Purity & Low Phase Noise
Featuring phase noise as low as -112 dBc/Hz at 10 kHz offset (10 GHz) and high spurious/harmonic suppression, the TG20A ensures clean, stable signals.
✅ Fast Switching & Advanced Pulse Modulation
The TG20A offers rapid frequency switching (as fast as 300 μs) and supports pulse modulation with a minimum pulse width of 100 ns and on/off ratio ≥65 dB, making it ideal for radar pulse simulation and time-critical testing.
✅ Compact Design & Full Remote Control
With a compact design and support for SCPI commands over USB/LAN, the TG20A easily integrates into automated test systems, benchtop setups, and rack environments, saving space while enabling seamless remote operation.
