of the LEDs show the status
of the rechargeable battery
(external power source, in-
ternal power source and
battery is charging) while
the fourth LED illuminates
when the R&S EFL210 is
turned on.
On the right side is a
„touch-knob“ that simu-
lates a mechanical rotating
knob; instead of turning a
knob, you merely pass your
finger (the thumb would be
best) over the touch knob.
The touch sensor works per-
fectly making it easy to use,
for example, for extreme
fine frequency adjustments.
The sensitivity of the sensor
can be adjusted to your per-
sonal tastes in the analyzer
settings but the default set-
tings worked just fine for our
Surrounding this touch-
knob are another 15 buttons
that provide direct access to
all of the R&S EFL210‘s func-
tions. After a short break-in
period you‘ll hardly need to
access the menu since less-
used menu pages can be ac-
cessed through an additional
function of these buttons,
namely pressing and holding
the button for 2-3 seconds.
To further increase the tech-
nician‘s productivity, two ad-
ditional buttons are reserved
as function buttons that can
be programmed by the user
to any desired function.
In the middle there‘s a
high-resolution color monitor
that is exceptionally bright. It
has a resolution of 640x480
pixels and parameters such
as brightness, contrast and
color can, of course, be ad-
justed as needed. There‘s
also a special mode that pro-
vides for exceptional monitor
On the top side of the ana-
lyzer you‘ll find the HF input.
As you might expect with a
the input jack is designed
to be used with a variety of
swappable connectors („F“
connector, BNC connector,
etc.) that are naturally in-
cluded with the analyzer.
There‘s also a slot for an SD
memory card available (un-
fortunately, only SD cards
up to 2GB are recognized;
SDHC cards are not com-
patible), a USB interface
that allows you to connect
the R&S EFL210 to a PC, an
HDMI output and the power
1. The menu structure of the R&S EFL210 at
one glance. One can see that great care has
been taken to provide a user friendly and
logical menu structure that allows to quickly
access all functions of this instrument.

the test I was using the latest firmware
4. Let’s start configuring the R&S EFL210.
The built-in pre-amp can be turned on
or off and you can select the preferred
units for the measurements. This device
can be set to an automatic mode, which
will then output the common units for
different measurements. This is a highly
appreciated new feature.
5. Support for many different languages.
6. Using external amplifiers or other active
elements like switches or a LNB the output
voltage can be set. The included R&S EFL-
Z100 antenna needs to be powered with 13V
for the LTE band.
7. In the Antenna menu select between two
pre-configured R&S antennas, the EFL-
Z100 (included) and the R&S HE-300. Two
further antenna settings can be configured
by the user, who can then also set the
correct antenna factor (K). The K value
expresses the antenna gain for a given
frequency in MHz.
8. A unique feature with the R&S EFL210:
it can be pre-configured for up to four
different applications.
9. The R&S EFL210 can be configured for
low power consumption, which will allow
for a longer autonomy when running on
batteries. The drawback will be a less
bright screen, but it might get you around
for a particularly work intensive day. The
auto mode will try to give the best relation
of brightness and speed against battery
10. Being a handheld measuring instrument
for field use the R&S EFL210 features a
memory logger that allows to store the
measurements made.
11. There are different options within the
Memory/Logger menu. It is possible to
store the measurements and graphs and
to access SD type memory cards. This
is particularly important as technicians
are often on the field for days, generating
a lot of information. Using SD cards,
the data can be copied to them and
read on a PC without connecting the
R&S EFL210, allowing to write reports,
while the instrument is still available for
The MACROS option allows to define a set
of measurements exactly tailored to the
individual need. Once setup, you just run
the macro and the instrument will do all
measurements automatically.
12. Doing a regular scan. The R&S EFL210
will tune all frequencies of the selected plan
and provide a quick PASS/FAIL information
view, recording all relevant measurements.
These are stored and can be recalled at any
13. The R&S EFL210 supports SD cards
with sizes up to 2GB; SDHC cards are not
