Example of the Duty cycle Setting
(1)
Set the Square wave Duty cycle to 60%.
(2)
Press SHIFT + 7 (DUTY) keys, DUTY LED
⑩
is on,
then press 6 0 Hz/% .
(3)
Change the Duty cycle to 30%.
(4)
Use
◄
or
►
key to shift the flashing digit to “6”
position, then change the digit to “3” by rotating the knob
⑤
counterclockwise.
Note:
The duty cycle limit : 20%
～
80%.
The frequency limit : 1Hz
～
1MHz.
（
Though less than 1Hz can be set, It becomes DC output and High
or Low is output. When you set less than 1Hz things except every
50% it compared with the duty cycle.

4.8. TTL/CMOS Signal Output Function
This product provide a TTL/CMOS signal from Output
⑭
. The
frequency of TTL/CMOS output is identical to the main output
frequency. If the frequency needs to be modified, please refer
to 4.4 Frequency Setting.
1) Press SHIFT + 9 (TTL) button, The TTL LED
⑪
will
light to indicate that the TTL output function is activated and a
compatible TTL level signal will be obtained from TTL/CMOS
Output BNC connector
⑭
.
2) Pull out TTL/COMS knob
⑰
, the CMOS output function is
activated, then a compatible CMOS level signal will be
obtained from TTL/CMOS Output BNC connector
⑭
. Turn the
TTL/COMS knob
⑰
to adjust to the desired CMOS signal
level.
