Rise Time
1. Verify that the pulse generator output is off and then connect the probe to the oscilloscope.
2. Connect the probe inputs, through the adapters shown below, to the pulse generator output. Set the probe input leads
straight and parallel for best signal response.
3. Set the output of the pulse generator to 50 V, 1 kHz, and a 200 ns pulse output. (The probe input voltage will be
25 V d ue to the 2X attenuator in the circuit.)
4. Set the oscilloscope to 5 V/div, 10 ns/div, BW = full, ave
rage = 16.
5. Set the probe bandwidth to full and the attenuation to th
e first range listed in the table.
6. Enable the generator output and check that the rise tim
e does not exceed the target rise time value listed in the table.
Use the auto-measure feature of the oscilloscope to determine the rise time.
7. Recordtherisetimeinthetestrecord.
8. Set the probe attenuation to the next range and adjust the vertical volts/div to display the signal.
9. Record the rise time in the test record and disable the generator output.
