How do you represent pulse in PSPICE?
The parameters for the pulse (to be entered in the order given) are:
- V1 is the value when the pulse is not “on.” This can be zero or negative as required.
- V2 is the value when the pulse is fully turned on.
- Td is the time delay.
- Tr is the rise time of the pulse.
- Tf is the fall time in seconds of the pulse.
How do you use a pulse generator in PSPICE?
A voltage pulse or pulse train can be applied as an independent source in PSPICE using VEXP. The VEXP voltage source generates a waveform as shown in figure 5, where TC1 and TC2 are the time constants of the rising and falling exponentials, respectively.
What is TD TR TF PW per?
pulse(V1 V2 TD TR TF PW PER) where. V1 = the initial amplitude V2 = the pulse amplitude TD = the delay time in seconds TR = the rise time in seconds TF = the fall time in seconds PW = the pulse width in seconds PER = the period in seconds An example of such a pulse generator is shown below.
What is a pulse voltage source?
Description. The Pulse Voltage Source block represents a voltage source whose output voltage value is a periodic square pulse as a function of time and is independent of the current through the source.
What is PER in pspice?
TR is the rise time of the pulse. PSpice allows this value to be zero, but zero rise time may cause convergence problems in some transient analysis simulations. The default units are seconds. TF is the fall time in seconds of the pulse. PER is the period and is the total time in seconds of the pulse.
What is the function of .probe command in pspice?
PROBE command writes the results from DC, AC, and transient analyses to a data file used by Probe. . END (end of the circuit)-The . END command marks the end of the circuit.
What is PER in PSpice?
What is TD in Vpulse?
t is an instance of time. tTD is the Time Delay. tRT is the Rise Time. tPW is the Pulse Width and.
How is pulse width measured?
Pulse Width (PW) is the elapsed time between the rising and falling edges of a single pulse. To make this measurement repeatable and accurate, we use the 50% power level as the reference points. The basic unit of measure for PRF is hertz (Hz). Use PRF to report the number of pulses per second.
What is the function of PSpice?
PSPICE is a circuit analysis tool that allows the user to simulate a circuit and extract key voltages and currents. Information is entered into PSPICE via one of two methods; they are a typed ‘Net List’ or by designing a visual a schematic which is transformed into a netlist.
What are the parameters of a PSPICE circuit?
The PSPICE schematic for this circuit is shown in figure 3. Figure 3. PSPICE Schematic Note that the pulse parameters are set to be: TD = 0 (no delay, start the pulse train at t = 0) TR = TF = 1n (10-9 makes the rise and fall times almost zero) V1 = 0 (pulse starts at zero) V2 = 1 (rises to one volt) PW = 1 (pulse width is 1 second)
Which is the rise time of the pulse in PSpice?
Tr is the rise time of the pulse. PSpice allows this value to be zero, but zero rise time may cause convergence problems in some transient analysis simulations; i.e., there is a very good reason for the existence of this parameter. The default units are seconds. Tf is the fall time in seconds of the pulse.

How to sweep duty cycle of a pulse train in PSpice?
You need to use a comparator, or something with a comparator’s properties. I used LTspice’s Schmitt A-device, which has complementary ouputs (you can ignore the negated one) and is set with a 1mV positive hysteresis, in order to directly compare with an VCVS ( E1 in the schematic) transformed to behave similarly to a comparator.
