MSG-2280 FM Stereo/FM-AM Standard Signal Generator
| This MSG-2280 high-performance digital standard signal generator adopts the DDS (Direct Digital Synthesizer) method. The wide frequency of this unit ranges from 100kHz to 170MHz covering the weather band, and it is provided with a built-in FM stereo modulator, so that this unit is the most suitable for adjusting and inspecting multi-band receivers. Owing to the adoption of the DDS method, the frequency settling time is shorter than 10ms, so that the GP-IB measuring time can bIn addition to its high performance and multiple functions, all operation is controlled by a microprocessor to ensure easy operation and rapid work. This unit is also provided with GP-IB, RS-232C, and EXT.I/O external control interfaces as standard so that it can be converted into an automatic measuring system. |
| ■ | Digital standard signal generator adopting the DDS method Owing to the adoption of the DDS method, this MSG-2280 signal generates precise RF frequencies over a wide range of 100kHz to 170MHz in addition to AF frequencies by its built-in AF oscillator. |
| ■ | 10ms settling time Adopting the DDS method ensures a high settling speed of frequencies and the response time is shorter than 10ms. |
| ■ | 100kHz to 170MHz wide band Its frequency range extends over a wide range from 100kHz to 170MHz covering the AM band, FM band, and weather band. |
| ■ | Electronic attenuator Its highly reliable electronic attenuator ensures a long-time continuous use, and the output level (-20dBµV to 126dBµV) can be switched quickly and precisely. |
| ■ | An FM stereo modulator is built-in This unit comprises MONO, MAIN, L, R, SUB, and OFF modulation modes and its L/R separation exceeds 60dB. |
| ■ | Multi-functions This unit can execute AM/FM simultaneous modulation for testing the suppression degree of multi-pass signals. Its output AGC and limiting sensitivity can be read directly by its ΔdB function. It can also read the detuning frequency, etc. easily and directly by its ΔF function.Pre-emphasis can be set to OFF, 25µs, 50µs, and 75µs. |
| ■ | Memory function and interface Data of 100 points can be stored and recall out by its memory function.This unit is also provided with GP-IB, RS-232C, and EXTI/O external control interfaces as its standard equipment so that it can be converted into an automatic measuring system. |
