Excellent SSB phase noise
The S1435-V series signal generator provides two steps of SSB phase noise for users. The standard SSB phase noise is measured at -104dBc/Hz (6GHz@10kHz), and the SSB phase noise can be as low as -120dBc/Hz (6GHz@10kHz) when the low phase noise option is selected. Users can select the phase noise as required to achieve the optimal cost performance.
It covers a frequency range of 9kHz to 6GHz.
-
High output power
When the H08 high-power output option is selected, the measured value of the full-band output power of the S1435-V series signal generator can be above 20dBm. In the test where high-power excitation signals are required, the S1435-V series signal generator can be used to obtain the required test signal without an external amplifier.

High-sensitivity LED touch screen
The 7-inch wide LED display which supports a resolution of 800 × 480 pixels clearly shows the instrument status information. The combination of the capacitive screen and the tailored window interface enables the S1435-V series signal generator to respond sensitively and accurately to users’touch operations. In addition to the touch screen, the user can also operate the instrument by the panel buttons, the rotary knobs (with the Enter function), and the external keyboard and mouse conveniently and quickly.
