S1435-V Series Signal Generator

Based on innovative technologies, the S1435-V series signal generator achieves balance in terms of performance, economy and volumetric weight. It supports arbitrary modulation of wave data downloaded in 5 formats, and enables users to edit, download, and configure the waveforms as required to complete various signal simulations and meet the testing requirements of various complex signals. Its baseband signal generator is easy to set up and has excellent performance. It supports real-time occurrence of general digital modulation signals in more than 20 formats such as PSK, QAM, FSK and MSK. It also has excellent spectral purity, with a single side band (SSB) phase noise of – 136dBc/Hz (when the carrier is 1GHz and the frequency offset is 10kHz) or -120dBc/Hz (when the carrier is 6GHz and the frequency offset is 10kHz). It provides a high power output and a large dynamic range, with the maximum output power up to 22dBm@3GHz and an output power dynamic range greater than 150dB. Besides, it 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, and thus is easy to carry. It can achieve exceptional performance even in a compact space, which meets both the test requirements for high performance in the equipment development phase and the test requirements for high efficiency in the production phase.

Key Features

High compatibility, downloading of arbitrary wave data in various formats

Complete universal digital modulation modes

Excellent SSB phase noise

High output power

Small size and light weight

High-sensitivity LED touch screen

  • Complete universal digital modulation modes

    The S1435-V series signal generator supports real-time occurrence of universal digital modulation signals in more than 20 formats, including PSK, QAM, FSK and MSK.

  • 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.
