MEASure Subsystem

FALLtime?

FALLtime?
Query :MEASure:[SOURce CHANnel<N>;]FALLtime?
The FALLtime query makes a fall time measurement on the selected
channel. The measurement is made between the 90% to the 10% voltage
point of the first falling edge displayed on screen.
Returned Format
[:MEASure:FALLtime] <value><NL>
1 through the number of channels in the oscilloscope connected as one unit
<N>
(maximum of 8 channels), otherwise the maximum number of channels is 2
time in seconds between the 90% and 10% voltage points of the first falling
<value>
edge displayed on the screen
Example
OUTPUT XXX;":MEASURE:SOUR CHAN2;FALLTIME?"

FREQuency?

Query :MEASure:[SOURce CHANnel<N>;]FREQuency?
The FREQency query makes a frequency measurement on the selected
channel. The measurement is made using the first complete displayed cycle
at the 50% voltage level.
Returned Format
[:MEASure:FREQuency]<value><NL>
1 through the number of channels in the oscilloscope connected as one unit
<N>
(maximum of 8 channels), otherwise the maximum number of channels is 2
frequency in Hertz
