Hint2:
Using this function, you can also
convert
units. Simply “freeze” the rea-
ding with HOLD, and then choose a different unit. The conversion is being
shown immediately!
Hint3:
You can force display of the selected unit in the large Info field by pres-
sing the menu key twice. The text in the large Info field will then be “overwritten”
by display of the unit.
7.14 MrkCnt
(Set number of markers)
MrkCnt
is used to set the number of markers. Possible values are 1,2 or 3.
If you only need to measure one frequency you should reduce the number of
markers to “1”. You then get a very stable display with no “jumping“ markers after
every sweep.
7.15 MrkLvl
(set starting level of markers)
With
MrkLvl
, you can configure the reference level from which
markers
or
exposure limit calculations
and
readings in W/m²
will be displayed. Three
settings ranging from -30dBm to -90dBm are available.
At the -30dBm setting,
markers
are only shown starting from a very high signal
strength of -30dBm. At -90dBm, even the weakest signals, but also other inter-
ference and noise are being shown as
markers
. The -70dBm setting mostly
offers the best results (default setting).
7.16 MrkDis
(change marker display)
The
Marker Display Mode
configures how
markers
are displayed. As the indi-
vidual display fields for
markers
are very different regarding size and readabili-
ty, two configurations are available:
Freq.
(frequency) displays the frequency of the markers in the bigger display,
and the amplitude (signal strength in dBm) is displayed in smaller versions.
Ampl.
(amplitude) displays the amplitude (signal strength in dBm) of the mar-
kers in the bigger display. The respective frequencies are displayed in smaller
versions.
Usually, you will use the
Freq.
mode, as the frequencies are often the most
