Waveform Output
FY2300H 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. 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”.

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 = 2

Sweep Type
FY2300H provides Linear, Logarithm sweep types. The default is Linear
sweep. The sweep type can be switched by pressing “MODE” button.
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 — Start value）/（Sweep time*100）
Logarithm Sweep
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 (F
start
), Stop Frequency (F
end
) and Sweep Time (T
sweep
).
The function prototype of Logarithm Sweep:

is the instantaneous frequency of the current output. P and T could be
expressed as shown below by the above-mentioned parameters:

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:
Start Frequency < End Frequency: the generator sweeps from low
frequency to high frequency.
Start Frequency > End Frequency: the generator sweeps from high
frequency to low frequency.
Start Frequency = Stop Frequency: the generator outputs with a fixed
frequency.
When Sweep function is enabled, press STAR button to highlight start value. Use
arrow buttons and ADJ Knob to set the specified value. Different frequency sweep
corresponds to different start frequency and end frequency range.
Sine： 100mHz to 25MHz~60MHZ (Varies according to different model)
Square： 100mHz to 25MHz
Ramp： 100mHz to 10MHz
Arbitrary：100mHz to 10MHz
The generator will restart sweep (according to the current new configuration)
from the specified “start frequency” after start or end frequency is changed.

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
FY2300H 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:
Select on FY2300H as master machine. Press SYS -> CONF ->M/S, to set
the UPLINK MODE to be “Master”. Press UPLI, to set the UPLINK to be
“ON”.
Set all other machines to be slave machines. Press SYS -> CONF ->M/S, to
set the UPLINK MODE to be “Slave”. Press UPLI, to set the UPLINK to be
“ON”. Repeat this step to set all slave machines.
Connect all FY2300H in parallel by TTL_IO connecter.
The uplink machines cannot exceed 8 because the driving ability.
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.

Troubleshooting
This chapter lists the commonly encountered failures of FY2300H and their
solutions. When you encounter these problems, please solve them following the
corresponding steps below. If the problem remains still, please contact FeelTech
and provide the device information (Press SYS to get it).
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) 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.
2). Please use original data cable.
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.
