1. Weromstjoer & Wiksel Belied
Wy akseptearje allinich items kocht fan roymall.com. As jo keapje fan ús lokale distributers of oare detailhandelaren, kinne jo se net weromstjoere op ús side.Lêste ferkeap items of frije kado's binne net akseptabel foar in weromstjoer.Om yn oanmerking te kommen foar in weromstjoer, moat jo item ûnbrûkt wêze en yn deselde steat dat jo it ûntfongen hawwe. It moat ek yn de orizjinele ferpakking wêze.Nei it ûntfangen fan weromstjoer ynstruksjes fan ús, pakket jo weromstjoerde items yn en droech jo pakket ôf by it lokale postkantoar of in oare koerier. Wy sille jo weromstjoer of wiksel item ferwurkje binnen 3-5 wurkdagen nei't wy it ûntfange. De weromstjoering sil wurde ferwurke en automatysk kreditearre oan jo orizjinele betelmiddel.Gjin weromstjoeringen of wiksel kinne akseptearre wurde as it produkt oanpast waard produsearre, ynklusyf oanpaste maat, oanpaste kleur, of oanpaste printe.Mear help nedich, nim dan kontakt mei ús op. service@roymall.com of Whatsapp: +447549870296
2.Weromstjoer Belied
Jo krije in folsleine weromstjoering of 100% winkel kredyt nei't wy it weromstjoerde pakket ûntfange en it kontrolearje. De weromstjoering sil wurde ferwurke en automatysk kreditearre oan jo orizjinele betelmiddel.Tink derom dat ferstjoerkosten en eventuele rjochten of fergoedingen net weromstjoerd wurde kinne. De ekstra ferstjoerkosten binne net weromstjoerdber as it pakket al ferstjoerd is. Jo binne ferantwurdlik foar it beteljen fan dizze kosten en wy kinne se net ôfslachtigje of weromstjoere, sels as de oardering weromstjoerd wurdt nei ús. As wy jo weromstjoerde item ûntfongen hawwe en befêstige, stjoere wy jo in e-mail om jo te warskôgjen dat wy jo weromstjoerde item ûntfongen hawwe. Wy sille jo ek ynformearje oer de goedkarring of ôfkarring fan jo weromstjoering.As jo problemen hawwe mei it weromstjoer proses, nim dan kontakt mei ús op. service@roymall.com of Whatsapp: +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.
