Set duty cycle (square wave)
Duty cycle is defined as the percentage of the duration of the high level of the
square wave in the cycle, as shown in the figure below. This parameter is only
valid when square wave is selected.
The setting range of duty cycle is limited by the “
FREQ
” setting. Please refer
to “
Waveform Characteristics
” in “
Specifications
”. The default value is 50%.
1.
Press the
DUTY
soft key to highlight the duty cycle 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.
a.
The adjusting range of duty cycle of this instrument is 0.01% - 99.99%.
b.
Press the OK key in the duty cycle adjustment state, and the duty cycle
will be initialized to 50.0%.
2.
Press duty cycle repeatedly to switch between rising edge time and falling edge
time.
Set pulse width (pulse wave)
The adjustable pulse wave refers to a square wave that can maintain a fixed
pulse width at any frequency, that is, the pulse width set by the user does not
change with the frequency change.
Pulse width setting method: when the tunable pulse wave is
selected, press the time key to adjust the duration of the pulse width t
(NS).
Pulse width can be set by direction key and parameter adjusting knob. Use
the direction key to move the cursor to select the position to be edited, and then
turn the knob to modify the value.
