OS-10V 02/04/2001 Rev.2 4.3 TIME MEASUREMENTS 4.3.1 TIME SPACE MEASUREMENTS This is a procedure for making time (period) measurements between two points on a waveform: (1) Connect the signal to be measured to the input terminal [18]. (2) Adjust level to obtain steady waveform. (3) Turn VAR clockwise to the calibration position, and set sweep controls to obtain a normal display of 1-2 signal cycles. - Page 12 OS-10V 02/04/2001 Rev.2 For rise time and fall time measurements, the 10% and 90% amplitude points are used as starting and ending reference points. (1) Apply a signal to the input jack [18]. (2) Use the VOLTS/DIV and VAR controls to adjust the waveform peak to peak height to five divisions.
- Page 13 OS-10V 02/04/2001 Rev.2 There are some cases which X axis requires control from external signals, e.g. external connection of sweep signals, signals of Lissajous pattern or other equipment’s display setup. X-Y mode operation is turn [10] to EXT/X, input signals through [13], sensitivity to be adjusted directly with [14], then input Y signal through [18].
