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 user-defined waveform. It can also

output TTL electric level. Both channels are completely independent

It has friendly human-machine mutual interface. 2.4 inch TFT Color LCD with

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

Waveform Output

FY2300 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 10Vpp amplitude by default. 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 Points：

1． What’s the difference of amplitude in Vpp and the corresponding value in Vrms?

Answer:

Vpp is the unit for signal peak-peak value and Vrms is the unit for signal effective value.

The default unit is Vpp.

Note：

For different waveforms, the relation between Vpp and Vrms is different. The relation of the two units is as shown in the figure below (take sine waveform as an example).

According to the figure above, the conversion relation between Vpp and Vrms fulfills the following equation:

Vpp = 22Vrms

For example, if the current amplitude is 5Vpp, For sine waveform, the converted value is 1.768Vrms.

Linear Sweep

In linear sweep type, the signal parameter varies linearly. For example, in the frequency sweep the output frequency of the instrument varies linearly in the way of “Changing several Hertz per second”. The variation is controlled by “Start Frequency”, “End Frequency” and “Sweep Time”.

The step value of linear sweep object is computed by the generator, the

formula is as follows:

Step value=（End value

Logarithm Sweep

Start value）/（Sweep time*100

）

In linear sweep type, the signal parameter varies logarithmically.

For example, in the frequency sweep the output frequency changes in the way of

“octave per second” or “decade per second”. The variation is controlled by “Start

Frequency”, “End Frequency” and “Sweep Time”.

When Logarithm Sweep is enabled, users can set the following parameters: Start Frequency (Fstart), Stop Frequency (Fend) and Sweep Time (Tsweep).

Enable Sweep Function

Press SWEEP button of front panel to enable sweep function. Then press ADJ Knob to start sweep process. Press ADJ Knob again to stop sweep.

Start value and End value

Start value and stop value are the upper and lower limits of sweep for specified parameter. sweep. The generator always sweeps from the start value to the end value and then returns back to the start value and continues indefinitely.

For example, in Frequency Sweep function:

Press SYNC button in system interface to enter synchronization setting interface. Press corresponding buttons on the right to highlight or cancel selecting status to set synchronization status of CH2.

When the synchronization of corresponding parameters are activated, the corresponding parameters of CH2 will vary according to variation of CH1 automatically. The parameters workable for synchronization include waveform, frequency, amplitude, offset, and duty cycle, which can be set separately.

When WAVE is highlighted, the waveform of CH2 will vary according to variation of CH1.

When FREQ is highlighted, the frequency of CH2 will vary according to variation of CH1.

When AMPL is highlighted, the amplitude of CH2 will vary according to variation of CH1.

When OFFS is highlighted, the offset of CH2 will vary according to variation of CH1.

When DUTY is highlighted, the duty cycle of CH2 will vary according to variation of CH1.

Uplink

FY2300 supports multi-machine uplink, which can provide users more channels for output. In uplink network, only one master machine can exist. Others must be set as slave machine. The setting method is as follows:

UPLINK MODE to be “Master”. Press UPLI, to set the UPLINK to be “ON”.

set the UPLINK MODE to be “Slave”. Press UPLI, to set the UPLINK to be “ON”. Repeat this step to set all slave machines.

When the setting above has been finished, all machines in network will work synchronously according to the start phase of master machine. When outputting signal with same frequency, multi channels output can be executed with phase adjustable.

Failure Phenomena

Solutions

The screen of the generator is still dark (no display) after switch on.

1) Check whether the power is correctly connected.

2) Check whether the power switch has been pulled in place.

3) Restart the instrument after finishing the above inspections.

4) Use USB-B cable to input power.

5) If it still does not work correctly, please contact

FeelTech.

. The screen of the generator is still dark (no display) after switch on, but the channel indicator lights illuminate.

This is because the power supply is not enough.

1). Please use original power adapter. If you need to connect to PC, please select USB port with enough current.

2). Please use original data cable because the original one has communicating function when supplying power, which others may don’t have.

3). Please do not repeat switching the power switch too soon. The instrument has power protection. Please wait for 2S at least to switch on after it is switched off.

CH2 is locked.

1) Check whether the generator is worked in synchronization mode. Press SYS button to enter system interface, then press SYNC button to enter synchronization setting interface and cancel all parameters selected.

2) If the problem is still, please restart the generator.

The settings are correct but there’s no waveform being generated:

1) Check whether the BNC cable is connected tightly with CH1 or CH2 connector.

2) Check whether the BNC cable has internal damage.

3) Check whether the BNC cable is connected tightly with the test instrument.

4) Check whether the indicators of CH1 or CH2 is turned on. If not press corresponding button to turn it on.

5) If the problem is still, please contact FeelTech.
