Oscilloscope Reference Measurement algorithms
Fall Time
3. From THF
, continue the search, looking for a crossing of LowRef.UpdateTHF if subsequent HighRef
crossings are found. When a LowRef crossing is found, it becomes TLF. (Use linear interpolation if
necessary.)
4. FallTime = TLF – THF
Frequency
Timing measurement. The reciprocal of the period. Measured in Hertz (Hz) where 1 Hz = 1 cycle per
second.
If Period = 0 or is otherwise bad, return an error.
Frequency = 1 / Period
High
100% (highest) voltage reference value. See High Low (see page 726).
Using the min-max measurement technique:
H
igh = Max
Low
0% (lowest) voltage reference value calculated. See High Low (see page 726)
Using the min-max measurement technique:
732 DSA/DPO70000D, MSO/DPO/DSA70000C, DPO7000C, and MSO/DPO5000 Series
