Me noho hoki ki te kōpaki taketake.I muri i te whiwhinga o ngā tohutohu hoki mai i a mātou, tēnā koa kōpaki i ō taonga kua hoki mai, ka tuku i tō kōpaki ki te poutāpeta ā-rohe, ki tētahi kaihere rānei. Ka tukatukahia tō hoki, tō whakawhiti taonga i roto i te 3-5 rā mahi i muri i te whiwhinga. Ka tukatukahia te moni hoki, ka hoki aunoa ki tō huarahi utu taketake.Kāore e taea te whakaaetia he hoki, he whakawhiti rānei mēnā i hangaia motuhake te hua, tae atu ki te rahi whaiaro, te tae whaiaro, te tā whaiaro rānei.Mehemea kei te hiahia āwhina anō, whakapā mai. service@roymall.com Whatsapp rānei: +447549870296
2.Kaupapa Moni Hoki
Ka whiwhi koe i te moni hoki katoa, i te 100% moni hoki toa i muri i te whiwhinga o te kōpaki kua hoki mai, me te tirotiro. Ka tukatukahia te moni hoki, ka hoki aunoa ki tō huarahi utu taketake.Kia mōhio, kāore e taea te utu hoki i ngā utu tuku, i ngā utu, i ngā utu rānei. Kāore e taea te utu hoki i ngā utu tuku taapiri ina kua tukuna te kōpaki. Kei a koe te kawenga ki te utu i ēnei utu, ā, kāore e taea e mātou te whakakore, te utu hoki rānei, ahakoa ka hoki mai te ota ki a mātou. I muri i te whiwhinga me te whakau i tō taonga kua hoki mai, ka tuku īmēra mātou ki a koe hei whakamōhio kua whiwhi mātou i tō taonga kua hoki mai. Ka whakamōhio hoki mātou ki a koe mō te whakaaetanga, te whakakore rānei o tō moni hoki.Mēnā he raruraru ōu e pā ana ki te tukatuka moni hoki, whakapā mai. service@roymall.com Whatsapp rānei: +447549870296

Features:
This manual applies to each model of FY8300S series Function/Arbitrary Waveform Signal Generator. The last three characters of the model indicate the up limit output of Sine Wave (MHz). For example, the u201c60Minchs of the Model Number u201cFY8300-60Minchs indicates the Sine wave maximum output frequency is up to 60MHz.
FY8300S series Three-channel Function / Arbitrary waveform generator is a set of Function Signal Generator, Arbitrary Waveform Generator, Pulse Generator, Analog / Digital modulator, Sweep, Counters and Frequency Meter and other functions in a high Performance, cost-effective, multi-function signal generator. Abundant shortcut keys and graphical user interface simplifies every operation. Users do not have to spend a lot of time to learn and familiar with the operation of the instrument, you can be skilled use. For education, research and development, production, testing, maintenance and other industries to provide a new choice.
The instrument adopt the Direct Digital Synthesizer (DDS) technology and provide stable, precise, pure and low distortion signals. Surface mounting technology improves interference immunity and operational life span. Can output up to 97 groups of functions / arbitrary waveform, contains 33 groups of preset waveforms and 64 groups of user-defined waveforms. Preset waveforms: Sine, Square, Rectangle (Duty Cycle adjustable), Pulse (Pulse width and cycle time can be set accurately), Triangle/Ramp, CMOS(0~12V), Four channels TTL, Exponential Rise, Exponential Fall, Noise, ECG, DC etc.

funciona bem, tem boas características, boas opções de modulação vco e sweep, porém somente o canal 1 pode receber modulação pelo canal 2, sweep somente no canal 1, vco somente no canal 1. canal 2 e 3 podem ficar ativos ao usar canal 1. a precisão de tensão não é muito boa, e onda quadrada tem overshoot elevado. interface pouco prática. mas é um bom gerador de baixo custo. este modelo está com o adesivo errado!
Very good value for money and fast shipping. The package arrived to EU for 14 days. The product covers the advertised specs and has intuitive user interface. The speed dial, soft keys and the display let you change all the parameters of the signal in a convenient way.
The device has proven to be precise and fully meets the characteristics specified by the seller and the manufacturer.
