FFR - Oscilloscope Automatic Measurement Type
FFR - is one of the auto measurement types of a digital oscilloscope located in the time domain (“Delay” menu item) which is used for the measurement of the time delay between the first falling edge of channel 1 and the first rising edge of channel 2. For more convenient display of a measured parameter the majority of oscilloscope auto measurement types are shown as abbreviations. Such short names contain the encoded meaning of the current auto measurement type. FFR abbreviation can be decoded as First Falling Rising. The example of the auto measurement of FFR delay time of Aktakom ADS-Series wide screen oscilloscope is shown on the screenshot below.
The measured delay time (t) between the first falling edge of channel 1 and the first rising edge of channel 2 on the screenshot above is 1.45 ns. |
