Note : Depending on whether you select a vertical or horizontal parameter, the correct units will be automatically
displayed (V, s, Hz, dB) in the Between and And fields. Or, if you select a simple ratio parameter (such as power
factor) that yields a dimensionless number, no units will be displayed.
6. Touch the Find Range button to quickly display the most recent value of the parameter measurement.
Waveform Gated Parameters
Setting Up Waveform Qualifiers
1. Touch Measure Measure Setup .
2. Touch a Px tab to open the setup dialog.
3. Touch inside the Source field and select a source from the pop-up menu.
4. Touch inside the Measure field and select a parameter from the pop-up menu.
5. Touch the Accept tab of the dialog on the right, then touch the Values Based on Waveform State
checkbox.
6. Touch inside the When Wform field and select the gating source.
7. Touch inside the State Is field and select High or Low from the pop-up menu. Parameter measurements
on the subject waveform will only be taken when the gating waveform is in the selected state.
8. Touch inside the Level Type field and select Absolute or Percent from the pop-up menu.
9. Touch inside the Level field and enter the crossing level value at which you want measurements to begin
using the scroll bar at the bottom of the window. Touch the keypad button to enter a value using
the pop-up keypad.
OR
Touch the Find Level button to automatically select the 50% level of your gating waveform.
EMC Parameters
Not available for all scopes, the EMC Pulse Parameter software package includes enhanced Rise@level,
Fall@level, Width@level, Time@level, and DTime@level parameters. The functionality includes user definable
thresholds for accurate pulse measurements.
% pk-to-pk is for ESD pulses that do not start at 0; they might go from negative to
positive or positive to negative voltage. The risetime is measured as a percentage of
peak to peak not base to top.
% 0-to-max is for ESD pulses that start at 0 V and reach a peak positive voltage. The
risetime is measured as a percentage of 0 to max instead of base to top of a traditional
IEEE pulse.
% 0-to-min is for ESD pulses that start at 0 V and reach a peak negative voltage. The
risetime is measured as a percentage of 0 to min instead of top to base.
