Product Features
Wide frequency coverage
The Ceyear 1433 Series covers a frequency range from 1 MHz up to 20 GHz, 26.5 GHz, 40 GHz or 50 GHz, depending on the model configuration. With a minimum frequency as low as 1 MHz and a maximum frequency up to 50 GHz, the series supports a wide variety of RF and microwave testing requirements.
High frequency resolution
With a frequency resolution of 0.1 Hz, the 1433 Series enables precise signal generation for applications that require accurate frequency setting and stable RF output.

Excellent phase noise performance
The 1433 Series provides excellent SSB phase noise performance, with a typical value of -110 dBc/Hz at 10 kHz offset from a 10 GHz carrier. This makes the instrument suitable for many demanding receiver, communication and RF system test applications.

Multiple modulation and sweep functions
The instrument supports CW signal output as well as FM, AM, Pulse and PM modulation. Step sweep and list sweep functions are also available, allowing engineers to simulate different signal conditions and perform flexible RF test procedures.
Various auxiliary test interfaces
The 1433 Series offers a range of auxiliary test interfaces, including reference input/output, pulse input, monitoring output and synchronization output. These interfaces support integration into more complex test setups and system-level verification environments.

User-friendly operation
The 8.4-inch high-brightness LCD touchscreen with 800 × 600 pixel resolution provides a clear display of instrument settings, parameters and operating status. The capacitive touchscreen and multi-window display make operation simple and efficient, especially during field testing.
Designed for field environments
The 1433 Series is designed for reliable operation in demanding working conditions, with an operating temperature range from -10°C to +50°C. Its compact handheld design makes it suitable for on-site measurements, maintenance work and portable test applications.
Flexible power supply
The instrument can be powered either by battery or by power adapter, giving engineers greater flexibility during field operation and mobile testing.
