GP-IB complying with an IEEE std.488-1975 The Composite Clipper, put on the back side of the stereo generator. ≦☑dB (20Hz to 15kHz with AF 1kHz reference) It is available on analogue, digital and MPX outputs for a precise and correct. (With AF 400Hz to 1kHz at 100% modulation in 76MHz to 108MHz) This composite signal, along with any other sub-carriers (SCA), modulates the FM transmitter. ±(setting×0.1+2)% (0.15MHz to 170MHz≦80%) The final multiplex signal from the stereo generator contains the Main Channel (L+R), the pilot tone, and the sub-channel (LR).
easily and directly by its ΔF function.Pre-emphasis can be set to OFF, 25µs, 50µs, and 75µs.ĭata 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. It can also read the detuning frequency, etc. Its output AGC and limiting sensitivity can be read directly by its ΔdB function. This unit can execute AM/FM simultaneous modulation for testing the suppression degree of multi-pass signals. This unit comprises MONO, MAIN, L, R, SUB, and OFF modulation modes and its L/R separation exceeds 60dB. Its highly reliable electronic attenuator ensures a long-time continuous use, and the output level (-20dBµV to 126dBµV) can be switched quickly and precisely. Its frequency range extends over a wide range from 100kHz to 170MHz covering the AM band, FM band, and weather band. 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.Īdopting the DDS method ensures a high settling speed of frequencies and the response time is shorter than 10ms. 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.ĭigital standard signal generator adopting the DDS method
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. 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. This MSG-2280 high-performance digital standard signal generator adopts the DDS (Direct Digital Synthesizer) method.
