Note:
1. Pulse width is restricted by minimum pulse width and pulse period
Minimum pulse width: 20ns;
Pulse width
≥
minimum pulse width;
Pulse width
≤
pulse period-minimum pulse width
2. Pulse duty cycle is restricted to minimum pulse width and pulse period
Pulse duty cycle
≥
100
×
minimum pulse width
÷

×
(1- minimum pulse width
÷
pulse period)
3. Pulse width is pertinent to the setup of duty cycle
ONE/10MHZ will vary based on the variation of the other. For example, current cycle is 1ms,
pulse is 500us and duty cycle is 50%, duty cycle will turn to 20% after pulse width is set to 200us.
Set rising/falling edge
1. Press
→
leading edge.
2. Enter the desired pulse rising edge.
3. Press
→
rising /falling edge
→
falling edge.
4. Enter the desired pulse falling edge.
2.1.5 Set noise wave
Press
and the operation menu of noise wave will be displayed at the bottom of the
screen. Use operation menu of noise wave to set its output waveform parameters.
Major parameters of noise wave include: amplitude/high level and offset/low level. Different noise
waves are obtained by altering these parameters. Noise is random signal without frequency and
periodicity. Specific interface is shown in Figure 2-12.
