Ceyear 1435 Series Signal Generator

Based on innovative technologies, the 1435 series signal generator achieves balance in terms of performance, economy and volumetric weight. 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 -116dBc/Hz (when the carrier is 10GHz and the frequency offset is 10kHz). It provides a high power output and a large dynamic range, with the maximum output power up to 20dBm@20GHz and an output power dynamic range greater than 150dB. 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 technologies, it can achieve high performance while reducing the cost. 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. The 1435 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.

Main Features:

1. Ultra-Wide Frequency Coverage & Serialization

Extended Spectrum: Depending on the specific model within the series, it spans from 100 kHz up to 3 GHz, 6 GHz, 10 GHz, 20 GHz, 40 GHz, 50 GHz, or 67 GHz (with option to select a minimum frequency of 9 kHz and maximum frequency expanding up to 70 GHz on specific configurations).

2. High Spectral Purity (Ultra-Low Phase Noise)

Pristine Phase Noise: The series is built for highly accurate local oscillator (LO) substitution and blocking tests. It delivers a typical single-sideband (SSB) phase noise of:
- -142 dBc/Hz at a 1 GHz carrier (10 kHz frequency offset).
- -126 dBc/Hz at a 10 GHz carrier (10 kHz frequency offset).
Spurious and Harmonic Rejection: It features advanced non-harmonic and sub-harmonic suppression to guarantee extremely pure signal output.

3. Broadband and High-Power Output Capabilities

Exceptional Drive Levels: It provides standard high-power handling, which can be further amplified using optional upgrades:
- H05 Option: Yields up to +22 dBm at 20 GHz, +20 dBm at 40 GHz, and +10 dBm at 67 GHz.
- H06 Option: Pushes the high-power performance up to +30 dBm (1 Watt) at 20 GHz.
This high direct output eliminates the need for external amplifiers, maintaining superior power accuracy and leveling stability.

4. Immense Power Dynamic Range

Extreme Sensitivity Range: Offers a vast 150 dB power dynamic range spanning from -130 dBm to +20 dBm (standard configuration), making it suitable for testing ultra-sensitive wireless receivers.

5. Advanced Modulation Capabilities

Analog Modulation: Comprehensive internal and external modulation resources supporting AM (linear depth >90% and exponential modes), FM (DC to 10 MHz bandwidth), and $\Phi$ M (Phase Modulation).
High-Performance Pulse Modulation: Features a pulse modulation depth greater than 80 dB, rapid rise/fall times under 10 ns, and a minimum pulse width of 20 ns. The built-in pulse generator includes 6 distinct pulse modes and supports complex pulse trains needed for specialized radar simulations.
Vector Modulation (1465-V Models): Integrates an internal baseband generator providing a 200 MHz internal vector modulation bandwidth and up to 2 GHz external modulation real-time bandwidth. It yields an Error Vector Magnitude (EVM) of less than 1.4% across universal digital modulation schemes (QAM, PSK, FSK, ASK).

6. High Frequency & Power Stability

Rock-Solid Time Base: Features a highly stable internal reference with a time-base aging rate of $\pm5 \times 10^{-8}/\text{year}$ (and less than 0.5 Hz variation per year for its 10 MHz high-stability time-base).
Thermal Rigor: After continuous power-on cycles over a 15-day stretch through shifting temperatures ( $0^\circ\text{C}$ to $50^\circ\text{C}$ ), the absolute power variation remains under 0.2 dB.

7. Modern Interface and Graphic Guidance

Large Touchscreen Layout: Equipped with a bright, 10.1-inch LED display supporting a 1280×800 resolution.
Flexible UI Controls: Features color-coded menus and an interactive graphical signal-flow diagram that visualizes parameter changes intuitively. Controls can be manipulated via the touch panel, manual entry knobs, physical shortcuts, or an attached mouse/keyboard.
Control Interfaces: Comes standard with LAN, USB, and GPIB (IEEE-488) connections for easy multi-client automated deployment using SCPI commands.
