FY2200S Series

Programmable dual-channel function generator

This instrument uses a large CMOS High speed integrated circuits, microprocessors, internal circuits using Active Crystal base, high signal stability. Surface mount technology greatly improves the immunity and longevity. Instruments have the dual DDS signal outputs can generate sine wave, square wave, triangle wave, sawtooth wave, the output signal amplitude, offset, phase control can be achieved (the instrument can display the output signal's amplitude and phase, waveform, parameter information, make your operation more convenient) 。 Also has dual TTL output (tunable phase difference), the measured frequency and the counter function, the product also has a linear sweep, and logarithmic sweep function, can set arbitrary scan frequency range and scan time. Are electronics engineers, laboratories, production line and the ideal equipment for teaching and research, but also can be used as industrial equipment supporting modules.

FY2200S Models in the last two digits 00 Value that represents the sine wave frequency limit of this type of instrument ( MHz )。 Example:FY2205S,05said this type of sine wave output frequency can be as high as 5MHz.

 High frequency precision: frequency accuracy can be achieved 10-6 Orders of magnitude

 High frequency resolution: full-range frequency resolution 10mHz

 The duty cycle can be adjusted independently of the main and auxiliary ( 1%~99% )

 Infinite ride restrictions: full range of frequencies are not graded, direct digital settings

 Waveform and high precision: calculated by a function of output waveform synthesis, waveform and high precision, low distortion

 Variety of waveforms: sine, square wave (duty cycle adjustable), triangle wave, sawtooth wave

 Scanning: with linear sweep and logarithm of the frequency scan function, the scan start and end points can be set

 Stores feature: stores 20 Set instrument parameters set by the user, and may at any time call up to reproduce

 Operation: all buttons, LCD1602 English LCD display, direct digital continuous adjusting settings or knobs

 High reliability: large-scale integrated circuits, surface-mount technology, high reliability, long service life

 Frequency measurement: 60MHz Frequency meter function, internal / External signal frequency measurement
