SPG-series signal generators
SPG signal generator creates harmonic signals with frequency tuning range from 20 to 6/12/20 GHz with 1 Hz step and power tuning range from −40 to −10 dBm with 1 dB step. The output signal can be modulated by an internal or external source.

The SPG signal generator is widely used for communication, navigation, and instrumentation applications.

Main functions
— CW signal generation with stepped frequency and
power tuning.
— Frequency and power sweep, list with predefined
trigger source.
— Modulated CW signal generation with internal or
external modulations source.
— CW low frequency and standard shapes signal generation
with stepped frequency and amplitude tuning.
— SCPI command system ensures the flexible embedding
in complex systems.
— Easy to use
— List editor
— Preset save and load
