S1435 Series Signal Generator

Overview Specifications Ordering Resources

S1435 series signal generator achieves balance in terms of performance, economy and volumetric weight. It responds fast and switches to another frequency in only 1ms, which shortens the test time and improves test efficiency, meeting the needs of massive data testing. In addition, it also has excellent analog modulation and pulse modulation functions. By adopting advanced frequency synthesis and RF channel signal processing technology, it can achieve high performance while reducing the cost.

Besides, S1435 series signal generator is equipped with a 7-inch high-sensitivity LED touch screen, and supports operation by touch screen, panel buttons, rotary knobs, external mouse and keyboard, etc., which fully upgrades the users’ operation experience. It adopts portable 3U chassis structure and is featured by small size and light weight. The S1435 series signal generator can meet both the test requirements for high performance in the R&D phase and the test requirements for high efficiency in the production phase.

High Performance Pulse Modulation

S1435 series signal generator provides Narrow Pulse Modulation Option (H04).

When the option H04 with a minimum pulse width of 20ns, a pulse width range of 20ns-42s-10ns and a step of 10ns is selected, it supports various triggering modes such as gating and external triggering. It’s also equipped with the pulse string required in radar test.
Multi-function Function Generator

The multi-function function generator consists of seven waveform generators for generating AM/FM/ΦM modulated signals and low-frequency output signals. Two waveform generators can generate a dual-tone modulated signal by internal addition and are used for AM/FM/ΦM.

The seven waveform generators include two standard function generators, one double-function generator, one scan function generator, two noise generators, and one DC generator.
Excellent SSB Phase Noise

S1435 series signal generator provides Low Phase Noise Option (H06).

1435 series provides two steps of phase noise for users. The standard phase noise is measured at -101dBc/Hz (10GHz @10kHz), and the phase noise can be as low as -116dBc/Hz (10GHz @10kHz) when the low phase noise option is selected.
High Output Power

S1435 series signal generator provides High Power Output Option (H08).

When option H08 is selected, the measured value of the full-band output power of the 1435A/B/C/D series signal generator can be above 20 dBm and the full-band output power of the S1435F series signal generator can be above 17 dBm.

In the test where high-power excitation signals are required, the 1435 series signal generator can be used to obtain the required test signal without an external amplifier.
