Probe cursors

If you press the left arrow key (C3), the cursor will move to the left. Note that as you move the cursor, the values in the Probe Cursor dialog box change. 

The cursors are positioned at the leftmost data point of the first trace so they cannot be easily seen. A new dialog box is displayed on the Probe screen. This dialog box displays the coordinates of each cursor and the difference between the two cursors. (There are two cursors.)... 

Suppose we wanted to show the values of VIL) VIH, V0L, and V0H on the Probe screen. This can be done using the cursors. Rrst, select Window from the menus and then select the first plot we generated to display a trace of V(Vo) by itself on the Probe window ... 

Crosshairs appear on the Probe screen, and a dialog box displays the coordinates of the cursors. We would like to mark the point V0h and Vu.. We will search for the x-cooidinate x = Vn, = 2.44. Select Trace, Cursor, and then Search Commands from the Probe menus ... 

We have specified a linear sweep from -25°C to 125°C with 1-degree increments. Click the OK button to the schematic. Simulate the circuit and display the results with Probe. Add the trace IC (Q1) to plot the collector current. Use the cursors to label the end points of the range. 

We can now use the cursors to find the 3 dB frequency. (See Section 2.K for a full explanation of cursors.) To display the cursors, select Trace, Cursor, and then Display from the Probe menus. The cursors will appear ... 

Run the PSpice simulation Select PSpice and then Run from the Capture menu bar. When the simulation is complete, the Probe window will open. Add the trace DB(V(VO) ) to plot the gain in decibels. Use the cursors to label the mid-band gain, and upper and lower -3 dB frequencies. Your cursor values may be slightly different than those shown here. 

The time interval needed for the detonation wave to travel the pre-determined distance between two probes is measured using built-in cursors of the oscilloscope. The detonation velocity is then calculated as a quotient of the distance between two probes(d) and corresponding time interval (t). Similarly the VOD is...
