keys and the knob or press the
【
InBox
】
key to input specific values in the
input box to adjust the parameters, so that the offset is set to the desired value.
The amplitude range is affected by the offset setting, the larger the offset, the
smaller the amplitude range. When the waveform selects the DC level, the
offset is the voltage value of the DC level (the amplitude cannot be 0). Please
refer to the specification in the manual for the specific adjustment range.
(6) To Set Duty Cycle
The sine waveform and square waveform cannot adjust the duty cycle, and the
duty cycle will be displayed in gray-yellow on the screen. Bias sine waveform
and pulse waveform can adjust the duty cycle.
Press the
【
Duty
】
soft key to make the “Duty” highlighted. Use the direction
keys and the knob or press the
【
InBox
】
key to input specific values in the
input box to adjust the parameters. The default duty cycle is 50%. The
waveform is switched to pulse wave, and the duty cycle is continuously
adjustable from 0.01 to 99.99%.
(7) To Set Phase
Press
【
CH2
】
key to select CH2, at this time, the blue interface of CH2 is
mainly displayed at the lower part of the screen.
On the CH2 interface, press the
【
Phase
】
soft key to highlight “Phase”, and
use the direction keys and the knob or press the
【
InBox
】
key to input specific
values in the input box to adjust the parameters. The default phase difference
is 0.00°. Before setting the phase difference, please set the frequency
synchronization of CH1 and CH2 in the system settings.
(8) Observe the output waveform
Use BNC cable to connect CH1 and CH2 of JDS8000 machine to the
oscilloscope and observe the waveform of the oscilloscope. It is recommended
to use our standard Q9-Q9 cable to test the square wave, with small overshoot
and stable waveform.
(9) Loading and save
Press the
【
MEM
】
button shortly, the message box will display to load M00, and
at the same time enter the input box function, you can press the number keys
to input the position to be loaded (00-99 in total 100 positions) and then press
the OK key to adjust out parameters.
Press
【
SHIFT
】
+
【
MEM
】
key, save M00 is displayed in the message box,
you can press number key+OK key to save the parameter.
3.Modulation Mode Interface and Parameter Settings
The JDS8000 series generators can output modulated waveforms in single or
dual channels. Modulation is the process of processing the information of the
