Meas Setup
Avg Number
On Off
Press Avg Number (On) to specify the number of sweep averages used
when calculating the measurement result. The average will be
displayed at the end of each sweep.
Avg Number (Off) disables the
measurement averaging.
Harmonics Harmonics indicates the number of harmonics to measure before
computing the total harmonic distortion. The minimum number is 2
(only the fundamental and second harmonic will be measured). The
maximum number is 10.
ST/Harmonic
Auto Man
ST/Harmonic (Auto) sets the sweeptime to 200 divided by the resolution
bandwidth or 10 ms, whichever is greater.
ST/Harmonic (Man) allows you
to specify any sweeptime from 10 ms to the analyzer maximum. This
sweeptime is used only for measuring harmonics. The sweeptime set
before the measurement began is used for finding the fundamental.
Counter Zoom
On Off
Counter Zoom (On) ensures the correct operation of the internal
frequency counter when the resolution bandwidth is relatively narrow
compared to the starting span.
Counter Zoom (Off) turns the counter
zoom function off.
NOTE The measurements described above are those available in SA mode (see
Mode key). Other measurements are available in other modes if an
optional personality is installed.
