Front Panel Operations
Waveform Output
FY6200 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、CH2 keys are used to switch ch1 or CH2 to the currently selected
channel. When power on, ch1 is selected by default and displayed in yellow on the
top half of the screen. Press the CH2 key on the front panel to select CH2, which
is displayed in blue on the top half of the screen. After selecting the required output
channel, you can configure the waveform and parameters of the selected channel.
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
“Synchronizing”.

Set Frequency
Frequency is one of the most important parameters of the basic waveform.
The frequency can be set differently based on different signals and different
waveforms. Please refer to the description of “Frequency Characteristics” in
“Performance Specifications”. The factory default setting is 10KHz.
Press the FREQ soft key to highlight the frequency parameter. At this time,
use the direction key and knob to set the parameter value: use the direction key
to move the cursor to select the position to be edited, and then rotate the knob to
modify the value.
The frequency unit can be switched according to the user's requirements.
Press the OK key to change the frequency unit. The optional frequency units are:
MHz, kHz, Hz, MHz and μ Hz.

Set Amplitude
The settable range of amplitude is limited by the "frequency" setting. Please
refer to the description of "output characteristic" in "performance index". The
default is 5vpp.
Press the FREQ soft key to highlight the amplitude parameter. At this time,
use the direction key and the adjustment knob to set the value of the amplitude:
use the direction key to move the cursor to select the position to be edited, and
then rotate the knob to modify the value.
Key Points:
1．What is the difference between the amplitude in Vpp and the value in Vrms?
Answer：
Vpp is the unit of signal peak value, Vrms is the unit of signal effective value. Vpp is
used by default.
Explain:
For different waveforms, the relationship between Vpp and Vrms is different. Take the
sine wave as an example.
The relationship is shown in the figure below.
According to the above figure, it can be deduced that the conversion relationship
between Vpp and Vrms meets the following relationship：
Vpp = 2
2
Vrms
For example, for a sine wave with a current amplitude of 5Vpp, the converted value is
1.768Vrms.
