u2666 Standard dual full functional channels which are equivalent to two independent generators.
u2666 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.
u2666 Precisely adjust the phases of the two channels, P"recision can be 0.01°.
u2666 Min amplitude resolution can be up to 1 mV. Amplitude range is 0~24Vpp.
u2666 Duty-cycle of each channel can be adjusted independently0.01%-99.99%, the adjusting resolution is 0.01%.
u2666 -12V~+12V DC Offsets function. Resolution 0.001V.
u2666 Save function: It can save 20 sets user-set parameters and can be loaded at any time.
u2666 Communicating function: All functions can be controlled by PC program and the communication protocol is open for secondary development.
u2666 Output short-circuit protection: All channels can work more than 60 seconds when the load is short-circuited.
u2666 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.
u2666 Adopt ABS plastic shell with table type design. Use 100-240V (AC) wide range voltage power supply.
u2666 Can choose our FYA2000S series or FPA1000 series power amplifier to output 20W~100W signal in DC-10MHz width without any distortion.
