4.1.4.3 Using Markers

Depending on the draw type setting, four or six markers can be used
simultaneously. The Y axis value on a current trace is displayed next to each
marker on the screen, but the frequency information is not provided.
Activate the marker table to see both, the level and frequency information
when moving a marker to the specific frequency using the Marker Edit
function.
The maximum allowable input level of the
instrument is +25dBm. Do not connect the RF In
port of the instrument directly to the output port of
the system. An over power input degrades the
performance of the instrument and may cause a
malfunction of the instrument.
Do not connect the instrument to the antenna when
there is a risk of lightning. Electric shock may cause
a malfunction or damage the instrument.
