MKFC Frequency Counter
Syntax
Figure 7-166 MKFC Syntax
Description
The MKFC command activates a frequency counter that counts the
frequency of the active marker or the difference in frequency between
two markers. If no marker is active, MKFC places a marker at the
center of the trace and counts that marker frequency. The frequency
counter provides a more accurate frequency reading; it completes a
sweep, zooms in on the marked signal, goes into zero span, counts the
value, and then starts a new sweep. To adjust the frequency counter
resolution, use the MKFCR command. To return the counter value, use
the MKF command.
