Basic Waveform Output EN rise from 10% threshold to 90% threshold; while the trailing (falling) edge time is defined as the time required for the pulse amplitude to fall from 90% threshold to 10% threshold as shown in the figure above. The range of the leading/trailing edge time is limited by the pulse width currently specified as shown in the formula below. The edge time will be automatically adjusted to match the specified pulse width if the value currently set exceeds the limit value. Press [Wave] > Pulse softkey to select pulse wave function and press Edge Time softkey to enter the Edge Time sub-menu. Press Leading or Trailing softkey to highlight it.
At this point, use the numeric keypad to input the value and select the desired unit from the unit menu that pops up, or use the direction keys and knob to modify the current value. 1. For the input method of the value, refer to the introduction in " Parameter Setting Method ". 2. The edge time units available are sec, msec, μsec and nsec. 3. The leading time and trailing time are independent from each other and users can set them separately. 5.2.9 Enable the Channel Output After configuring the parameters of the waveform selected, waveform output could be enabled. Press [Output1] or/and [Output2] button on the front panel and the backlight of the button turns on.
The instrument outputs the configured waveform from the [Output1] or [Output2] connector on the front panel. 5.3 Basic Waveform Output Example Configure the generator to output a pulse waveform with 1.5MHz frequency, 500mVpp amplitude, 5mV DC offset, 200ns pulse width, 75ns leading edge time and 100ns trailing edge time. 1. Press [CH1/2] button on the front panel and select CH1. The corresponding area of CH1 in the user interface is illuminated. 2. Press [Wave] > Pulse softkey to select the pulse wave function. 3. Press Frequency softkey to highlight it. Use the numeric keypad to input the frequency value "1.5", and then select the desired unit "MHz" from the pop-up menu. 4.
Press Amplitude softkey to highlight it. Use the numeric keypad to input the amplitude value "500", and then select the desired unit "mVpp" in the pop-up menu. 5. Press Offset softkey to highlight it. Use the numeric keypad to input the offset 6. Press Width softkey to highlight it. Use the numeric keypad to input the width value value "5", and then select the desired unit "mV" in the pop-up menu. "200", then select the unit "nsec" from the menu that pops up.
