Excellent Single Sideband Phase Noise
1435 series signal generator offers two selectable phase noise modes. The standard mode achieves a measured single sideband phase noise of -101dBc/Hz at 10GHz @10kHz offset, while the optional low-phase-noise mode reduces this to as low as -116dBc/Hz at 10GHz @10kHz offset. Users can select the appropriate phase noise level based on actual requirements, achieving an optimal balance between performance and cost-effectiveness.

High-Performance Pulse Modulation
The instrument offers a pulse on/off ratio greater than 80dB, with rise and fall times of less than 10ns. When equipped with the narrow pulse option H04, the minimum pulse width can be as low as 20ns, with a pulse width range of 20ns to 42s–10 ns and a step size of 10ns. It supports various triggering methods, including gated triggering and external triggering, and also provides a pulse train function required for testing.

Multifunction Function Generator
The multifunction function generator consists of seven waveform generators, used to generate AM/FM/ΦM modulation signals and low-frequency output signals.
Among them, two waveform generators can be internally summed to generate dual-tone modulation signals for AM/FM/ΦM applications.
The seven waveform generators include:
-
2 x standard function generators
-
1 x dual-function generator
-
1 x sweep function generator
-
2 x noise generators
-
1 x DC generator
The DC generator produces a DC level and is only applicable to low-frequency output.
The sine wave frequency range of the waveform generators is 0.1Hz to 10MHz, while the triangle wave, square wave, sawtooth wave, and pulse wave have a frequency range of 0.1Hz to 1MHz, with a frequency resolution of 0.1Hz.
