Product Introduction
This manual applies to each model of FY6600 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 “60M”of the Model Number
“FY6600-60M”indicates the Sine wave maximum output frequency is up to
60MHz.
FY6600 series Dual Channel Function/Arbitrary Waveform Generator is a
multifunctional signal generator product integrating Function Signal Generator,
Arbitrary Waveform Generator, Pulse Signal Generator, Noise Signal Generator,
Counter and Frequency Meter with excellent cost performance. This instrument
adopts large scale CMOS integrated circuit and high speed MCU microprocessor.
The internal circuit uses SPXO as the basic standard to guarantee the stability of
signals. Surface mounting technology improves interference immunity and
operational life span.
This instrument has double channels can output 31 preseted DDS signals
including Sine, Square, Triangle(Ramp), Rise Sawtooth, Fall Sawtooth, Lorenz
Pulse, Multitone, Noise, Cardiogram, Trapezoidal Pulse, Sinc Pulse, Narrow
Pulse, Gauss White Noise, AM, FM, Step and 64 group user-defined waveform. It
can also output TTL electric level. Both channels are completely independent.

320×240 resolution can display all the parameters of both channels and current
functions of all buttons . Shortcut keys simplify all complicated operations and
save time. Users can be proficient after several minutes practice.
The advantages of this instrument in signal generating, waveform sweeping,
parameter measurement and other fields, make it to be the ideal equipment for
electronic engineers, laboratories, industry producing line, university, R&D
institutes and so on.

Front Panel Operations
Waveform Output
FY6600 series can output waveforms (Sine, Square, Triangle/Ramp, Pulse
and Noise etc.) from one of the channels separately or from the two channels at
the same time. At start-up, the dual channels are configured to output a sine
waveform with 10kHz frequency and 5Vpp amplitude by default. Two channels
use default setting saved at Position 1 when power on. Users can configure the
instrument to output various waveforms.
Select Output Channel
CH1 and CH2 buttons are used to change current channel selected. At
start-up, CH1 is displayed on the top with yellow color and CH2 is displayed on
the bottom with blue color. Press CH1 or CH2 to select channel needed. When
selecting CH2 as output channel, CH2 parameters displays on the top for
configuration.
KEY POINT:
CH1 and CH2 can not be selected at the same time. Users can first select
CH1 and then select CH2 after configuring the waveform and parameters of
CH1. If you need to change the parameters of two channel at same time,
please refer to Chapter “Synchronization”.
