4.3.3 PERFORMING TIME MEASUREMENTS
FREQ Frequency
Trte FREQ measurement is calculated between the MAIN CURSORS. It is
necessary to set the main cursors on the wanted trace, using the
CURSOR-SELECT menu, and on the required part of the signal using the
CURSOR-CONTROL menu (see also Section 3.2.7).
By activating the FREO calculation function the oscilloscope will automatically
measure the period time of the signal and will show the measuring points by two
small LOCATE CURSORS. Minimal one signal period should be covered by the
MAIN CURSORS- If the distance between the MAIN CURSORS is less then one
signal period, an error message is given.
The measuring result is shown in the right corner of the top text area.
FREQ : f = ... kHz
PERIOD Period
The PERIOD measurement is calculated between the MAIN CURSORS. It is
necessary to set the main cursors on the wanted trace, using the
CURSOR-SELECT menu, and on the required part of the signal using the
CURSOR-CONTROL menu (see also Section 3.2,7).
By activating the PERIOD calculation function the oscilloscope will automatically
measure the period time of the signal and will show the measuring points by two
small LOCATE CURSORS. Minimal one signal period should be covered by the
MAIN CURSORS. If the distance between the MAIN CURSORS is less then one
signal period, an error message is displayed.
The measuring result is shown In the top text area.
