S1131 RF Signal Generator

S1131 RF signal generator provides engineers with a “Smaller, lighter and easier” solution for 3GHz signal-generation applications. While it is an entry level instrument, the S1131 provides most commonly used functions an engineer needs such as CW signal generation, AM/FM/PM/Pulse modulation, digital modulation (ASK, FSK, PSK), Up-converting, LF output etc. S1131 also provides flexible interfaces and support SCPI for easy remote control. S1131 is perfect suitable for education, RF component manufacture and maintenance.
