    • ELEC 101 Lab 5
    • Lab 05 Objectives •  The student will be able to –  Open an existing project –  Create a new simulation profile –  Run a simulation and view the Probe output –  Modify the Probe ranges and grids for the X Axis and Y Axis –  Create a new project –  Create a new simulation for Bias Point Analysis –  Configure the schematic to display node voltages and branch currents February 2004 ELEC 101 Lab 5 2
    • Lab 5A Probe Window Output
    • Lab 5A Requirements •  Open Circuit from Disk •  Create a New Simulation Profile for AC Sweep Analysis •  Place a ground referenced VDB Marker •  Run the simulation •  View Probe Output •  Change the X Axis grid markers to make readings more accurate •  View Probe Output and make further modifications if desired February 2004 ELEC 101 Lab 5 4
    • Lab 5A Schematic February 2004 ELEC 101 Lab 5 5
    • Lab 05A Create New Simulation Profile CL on PSpice CL on New Simulation Profile February 2004 ELEC 101 Lab 5 6
    • Settings for New Simulation Profile February 2004 ELEC 101 Lab 5 7
    • Select Desired Marker for Probe Output February 2004 ELEC 101 Lab 5 8
    • Place VDB Voltage Probe at OUT February 2004 ELEC 101 Lab 5 9
    • Run the Simulation On the PSpice Toolbar, CL on the Run Button February 2004 ELEC 101 Lab 5 10
    • Lab 05A Probe Output X-Axis is not a linear scale. Reading frequencies is not accurate February 2004 ELEC 101 Lab 5 11
    • Changing X Axis Grid CL on Plot CL on Axis Settings February 2004 ELEC 101 Lab 5 12
    • Modify X Grid Intervals CL on the X Grid Tab Turn off Automatic and select 10 for Minor February 2004 ELEC 101 Lab 5 13
    • Revised Lab05A Probe Output The increased number of x axis markers makes the graph easier to read February 2004 ELEC 101 Lab 5 14
    • Lab 5B Probe Output Modification Add Traces
    • Lab 5B Schematic February 2004 ELEC 101 Lab 5 16
    • Probe Output for Transient Analysis February 2004 ELEC 101 Lab 5 17
    • Change the Y Axis Range February 2004 ELEC 101 Lab 5 18
    • Modified Probe Output February 2004 ELEC 101 Lab 5 19
    • Add a Plot on the Top of the Current One February 2004 ELEC 101 Lab 5 20
    • Probe Output with Additional Plot Window February 2004 ELEC 101 Lab 5 21
    • Select Add Trace from the Trace Menu February 2004 ELEC 101 Lab 5 22
    • Select the Waveform to Plot – VIN February 2004 ELEC 101 Lab 5 23
    • Revised Probe Output We can readily compare the relationship between the input waveform and the output current February 2004 ELEC 101 Lab 5 24
    • Lab 5C Bias Point Calculation
    • Lab 05C Overview •  In some cases we wish to determine an operating point –  this is called the Bias Point •  When Bias Point Simulation is performed in PSpice, it does not generate a Probe Output because no component values are swept. •  After running the simulation, close the probe Window and Select V or I from the toolbar to have Capture display all node voltages or all the branch currents. •  The student will Place a Net Alias (special text inserted in the schematic) to identify nodes of particular interest February 2004 ELEC 101 Lab 5 26
    • Lab 05C Schematic February 2004 ELEC 101 Lab 5 27
