1435A/B/C/D/F Signal Generator up to 40GHz

PRODUCT OVERVIEW

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.

FUNCTIONS & FEATURES

Wide frequency coverage

The 1435A/B/C/D/F series signal generator provides a frequency range of 9kHz~3GHz/6GHz/12GHz/20GHz/40GHz. Its lowest frequency can be as low as 9kHz and its highest frequency can be as high as 40GHz, which can meet the needs of wide frequency band testing.

High output power

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

Excellent SSB phase noise

The 1435 series signal generator provides two steps of SSB phase noise for users. The standard SSB phase noise is measured at -101dBc/Hz (10GHz@10kHz), and the SSB phase noise can be as low as -116dBc/Hz (10GHz@10kHz) when the low phase noise option is selected. Users can select the phase noise as required to achieve the optimal cost performance.

Extremely short frequency switching time

The 1435 series signal generator can realize fast frequency switching in the full frequency band, and the measured frequency switching time is 0.67ms, which can meet the test requirements for high speed.

High performance pulse modulation

The pulse switch ratio is greater than 80dB, and the rise and fall time is shorter than 10ns. When the narrow pulse 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. The DC generator generates DC levels, which can only be used for low frequency output. For the waveform generator, its sine wave frequency range is 0.1Hz~10MHz, and its frequency range of triangle wave, square wave, sawtooth wave and pulse is 0.1Hz~1MHz, and the frequency resolution is 0.1Hz.

Small size and light weight

By adopting the portable 3U-high chassis design, the 1435ABCDF series signal generator has its weight and volume greatly reduced (compared to bench instruments). The heaviest model of this series is 10.9kg, and the lightest model is 7.4kg.

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 1435ABCDF 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.

TYPICAL APPLICATIONS

General test

The 1435 series signal generator provides complete functions and a frequency range of 9kHz~40GHz. It provides AM, FM, ΦM, and PM analog modulation functions and supports step scan and list scan. Also, it has excellent performance. By adopting a design which realizes the balance between performance, economy and volumetric weight, it supports free configuration of various options, which makes it widely available. In respect of cost, it can be used for teaching; in respect of performance, it can be used in laboratory tests.

Defense test

The 1435 series signal generator supports high-performance pulse modulation, with a pulse-to-modulation switch ratio greater than 80dB, the rise and fall time less than 10ns, and the minimum pulse width of 20ns. It supports various pulse patterns such as pri stagger, prf jittering and pulse string, which is suitable for radar system testing. It has excellent phase noise performance and is available for receiver testing. It has a small size and can be carried along for field testing.

Production line test

The 1435 series signal generator takes only 1ms to switch to another frequency. It provides a high test speed, shortens the test time, and improves the test efficiency, thus meeting the requirements of massive data test. It provides a high power output and needs no external power amplifier, thus saving the space and cost. It supports multiple control interfaces such as USB, LAN and GPIB, which facilitates the formation of an automated test system and is suitable for production line test.
