Figure 47 Measurement Hold
Markers
Up to six markers can be used and activated to visually indicate the trace value at
specific frequency points. All markers follow the current trace only. The site ana-
lyzer displays the frequency and signal value for each marker at the bottom of the
screen. Each marker is displayed as a triangle pointer or a vertical line through the
trace. The difference (delta) in frequency between two markers can also be dis-
played. Markers indicate VSWR to 0.01, and Return Loss or Cable Loss to 0.1 dB.
When both a recalled trace and the current measurement trace is both dis-
played at the same time, there is an additional marker option, single mode and
dual mode. In single mode, the markers function normally (indicating the fre-
quency and value at the marker). In dual marker mode, select a marker using
the Mark softkey. At the bottom of the screen, the site analyzer will display the
marker number, the frequency, and the value of the current trace at the
marker. The difference in frequency and value between the current trace and
the recalled trace is also displayed. The difference in frequency is always 0.00
(zero). Only the first three markers (M1, M2, M3) are available in dual mode.
