Test System and Probe Rise Time
14. Disconnect the SMA cable and BNC adapter from the Channel 1 input of the 1103 power supply.
15. Connect the SMA cable to the BNC-to-probe tip adapter.
16. Connect the probe to the 1103 power supply channel 1 input and set the attenuation to ÷ 5.
17. Turn off the offset control on channel 1 of the 1103 power supply.
18. Connect the probe to the DM test points on the BNC-to-probe tip adapter.
19. Adjust the oscilloscope vertical scale to 20 mV/div, averaging on.
20. Adjust the oscilloscope horizontal positioning to place the rising edge of the signal so that it crosses the second vertical
and cent
er horizontal graticule lines.
21. Use the m
easurement capability of the sampling oscilloscope to display rise time.
Increas
e the stability of the pulse edge measurement by using averaging, if available. Rise time is determined from
the 10% and 90% amplitude points on the waveform.
22. Record the rise time as t
s+p
