All customers should contact us and obtain Return Merchandise Authorization (RMA) number before sending anything to us. We will not be responsible for returned item(s) without notifying us in advance.
Refunds
After receiving your return and inspecting the condition of your item, we will process your refund to the credit / debit card or PayPal account which was used to place the original order.
Please allow at least seven (7) days from the receipt of your item to process your refund. Refunds may take 1-2 billing cycles to appear on your credit card statement, depending on your credit card company. We will notify you by email when your refund has been processed.
Exceptions
If an item is found damaged or defective on receipt, we kindly ask you to contact us within 15 days from the delivery date to arrange a refund or exchange without physical return of the item.
Please provide us with following:
1. Photos of the front and back sides of the packaging box; 2. A photo, video or screenshot of the defective item or the defective part of the parcel.
Our customer service team will communicate with you to arrange a refund or reshipment without physical return of the item.
Warranty & Repair service
If any of the items you have purchased from us is found defective within 1 year from receipt, you are entitled to a repair under warranty. Please kindly provide us with evidence photos or videos of the defective item.

Note: Please be aware, we do not cover the cost of the returns fees in warranty & repair service.
Order Cancellation
If you want to cancel an order within 24 hours from confirmation of the payment, you will be entitled to a full refund. It is still possible to cancel an order after 24 hours, provided that it has not yet been shipped. If an order has been shipped, it’s impossible for us to cancel or modify it anymore. If you still want a refund, you required to return the item on it’s arrival.
Questions
If you have any questions concerning our return policy, please contact us at:
♦ Adopt the Direct Digital Synthesizer (DDS) technology and provide stable, precise, pure and low distortion signals.
♦ 2.4 inch TFT Color LCD with 320×240 resolution, displaying parameters and graphics of the two channels at the same time.
♦ The instrument uses 14-bit high-speed D/A converter chip (5Vpp output quantization error is less than 1mV), 250MSa/s sample rate, 14bits vertical resolution.
♦ 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 (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.
♦ Enable to store 64 arbitrary waveform data files, each one of waveform storage depth 8192 points * 14bits; (The longer the waveform storage depth, the more detail the waveform is saved, and the signal details can be restored with high p’recision.)
♦ Various modulation types: AM, FM, PM, ASK, FSK and PSK modulations.
♦ Sweep Function: It can sweep 4 properties of signals including frequency, amplitude, offset and duty cycle; It has Linear and Logarithm two sweep types; 0.01S~999.99S sweep time; Up, Down and roundtrip sweep directions.
♦ VCO Function(Voltage Control Output): Can be achieved by an external input signal: voltage controlling frequency, voltage controlling amplitude, voltage controlling offset, voltage controlling duty cycle and PWM modulations.
♦ Burst Output Function: There has Manual Trigger, internal CH2 Trigger, and External Trigger for your options. It can output 1~1048575 pulse trains.
♦ 100M Frequency meter function: It can measure frequency, period, pulse width and duty cycle. Max. frequency workable is 100MHz and Min. frequency workable is 0.01 Hz.
♦ Counter Function: It has 2 coupling measure modes including DC coupling and AC coupling. This design can solve inaccuracy problem of AC coupling.
♦ Standard dual full functional channels which are equivalent to two independent generators.
♦ Channel SYNC Function: Support waveform copy and state copy between channels.
Support two or more signal generators connected to achieve multi-channel output, the maximum support 16-channel synchronous output, the phase between each channel can be adjusted.
♦ Precisely adjust the phases of the two channels, P’recision can be 0.01°.
♦ Min amplitude resolution can be up to 1 mV. Amplitude range is 0~24Vpp.
♦ Duty-cycle of each channel can be adjusted independently0.01%-99.99%, the adjusting resolution is 0.01%.
♦ -12V~+12V DC Offset function. Resolution 0.001V.
♦ Save function: It can save 20 sets user-set parameters and can be loaded at any time.
♦ Communicating function: All functions can be controlled by PC program and the communication protocol is open for secondary development.
♦ Output short-circuit protection: All channels can work more than 60 seconds when the load is short-circuited.
♦ Provide powerful waveform editing PC software. Users can download arbitrary waveform to this instrument after edit through PC program which is included in user CD.
♦ Adopt ABS plastic shell with table type design. Use 100-240V (AC) wide range voltage power supply.
♦ Can choose our FYA2000S series or FPA1000 series power amplifier to output 20W~100W signal in DC-10MHz width without any distortion.
