Markers
You must be in either Measure Match mode or Fault Location mode to
use markers.
You can activate and use up to six markers to visually indicate the trace
value at specific frequency points. All markers follow the current trace
only. The site analyzer displays the frequency and signal value for each
marker at the bottom of the screen. You can display each marker as a
triangle pointer or a vertical line through the trace. You can also display
the difference (delta) in frequency between two markers. Markers indi-
cate VSWR to 0.01, and Return Loss or Cable Loss to 0.1 dB.
When you display both a recalled trace and the current measurement
trace at the same time, there is an additional marker option, single
mode and dual mode. In single mode, the markers function normally
(indicating the frequency and value at the marker). In dual marker
mode, you select a marker using the Mark softkey and, at the bottom
of the screen, the site analyzer displays the marker number, the fre-
quency and value of the current trace at the marker, and the differ-
ence in frequency and value between the current trace and the
recalled trace. The difference in frequency is always 0.00 (zero). Only
the first three markers (M1, M2, M3) are available in dual mode.
