1. If youopen the “LEAKAGE”menu, youwill
find a new option “AUTO CONFIG”. Select it
to automatically set the scale for the signal
level.Notice thecoloredbar in theupper right
corner?This indicateswhat color the respec-
tive signal level will have in thewaterfall dia-
gram. In this picture you see the setup prior
to activating this function. Take a look at pic-
ture 7 toseean ideal scale.
2. Another new option is “FRAME BEEP”.
You will find it in “LEAKAGE – WATERFALL
OPTIONS”.
3. If you turn “Frame beep on”, every time a
full waterfall diagram is rendered, i.e. 190
lines are scrolled upwards, the R&S EFL210
will soundabeep.
4. In“LEAKAGE–WATERFALLOPTIONS”you
will find thebrandnew function “SEARCHING
LEAKS”.
5. After activating this function, the R&S
EFL210 will search for CATV leaks in the LTE
band.
6. Notice the “Searching” in the lower right
corner. TheR&SEFL210 is actively searching
the LTE band for typical CATV patters which
result fromLeckage.
7. To try this function, I hooked up the R&S
EFL-Z100 antenna provided with the R&S
EFL210andstarted to look for leaks.Naturally
wedonot have leaks inour test center…
8. …so I produced a leak! Immediately the
R&S EFL210 issued a warning sound and
displayed “Cable leak detected!” on the
screen. While Rohde & Schwarz do explain
in the included “What’s new” document that
this function is not guaranteed to detect all
Leckages automatically, I must say that I am
quite impressedwithhowefficiently itworked
duringmy tests.
9. Another improvement in thisnewfirmware:
the noise level is always displayed in the
spectrum analyzer mode, making it easier to
detect very faint signals.
10. If you open the “EQUIPMENT CONFIG”
menu, you can setup the two functions keys
F1 andF2. Thiswas already possiblewith the
previousfirmware.
11. Just select “DIRECT KEYS” and then
either oneF1or F2.
12. The menu now shows two new entries.
I have set the F1 key with “Auto Config.”,
because I will use this function a lot - never
againwill I have tofiddlewith the color range
of thewaterfall diagram!
13. For the F2 key, I selected the new “Ext.
Amp.” entry. This allows me to turn the cur-
rent for the external amplifier on and off.
When using the R&S EFL-Z100 antenna, the
AIR band requires the amplifier to be turned
off,while theLTEband requires it tobe turned
on.
