23. As expected, the Spaun

Sparos 711 is capable of show-

ing a constellation diagram for

all modulations. We had previ-

ously fine-tuned our terrestrial

antenna with the help of this

meter, so the constellation dia-

gram shown here looks almost


24. One of the quadrants of the

constellation is enlarged in

this screenshot. This allows an

even closer look at the details,

even though this is not neces-

sary at all. Thanks to the large

and high-resolution screen of

the Spaun Sparos 711 it’s hard

to miss a thing in any display




12. In measurement mode the

Spaun Sparos 711 presents all

relevant information simultane-

ously. Seen here are the results

for a DVB-T transponder. To

access more detailed data you

only need to tap on measure-

ment, live spectrum, live video

or service information.

13. If you tap on the upper left

section of the display, which

shows the measurements, a

new screen is launched with all

measurement results as well

as corresponding reception


14. All those reception parame-

ters are presented with virtual

buttons. Simply tap on one of

the buttons to change any of

those details, including modu-

lation. The Spaun Sparos 711 is

wonderfully easy to use, since

all menu items always stay the

same, irrespective of the signal

that is being analysed. You can

switch from DVB-C to DVB-S

at any time without having to

leave measurement mode. This

may seem slightly weird at first,

but once you get used to this

process flow you don’t want to

change a thing about it.

15. The feature we liked best is

called Auto Lock. Using it lets

the meter identify all reception

parameters – fully automati-

cally and in record-breaking

time. It takes no more than 3

to 5 seconds until the signal

is correctly locked, even with

unconventional symbol rates.

This is an enormous help, par-

ticularly when it comes to ana-

lysing unknown transponders,

which is frequently required for

aligning satellite antennas to

more exotic orbital positions.

16. The spectrum display builds

up really quickly and offers

very high resolution. Seen here

is a yellow marker on a DVB-T

transponder with a frequency

of 754 Mhz. To the right you

can see an LTE signal, which

thankfully is spaced with

enough distance not to cause


17. If you tap on the quadrant

showing the live video this

screen section will be resized

to full-screen mode. Additional

options available in this mode

are volume adjustment, calling

up the service list or accessing

PID and NIT details. In addition,

this is where the ASI input can

be activated – this way the

stream to be analysed is no

longer the transport stream

provided by the built-in tuner,

but the transport stream that

is led into the ASI input. The

ASI output is active at any

time and gives out the active

transport stream. It should

be noted at this stage that the

currently selected channel can

be recorded onto an external

USB storage medium. A great

option if you want to have a

closer look at the MPEG stream

on your PC.

18. The volume can be adjus-

ted in full-screen mode. This

actually makes sense conside-

ring that it’s best to take care of

volume during playback rather

than hiding it in a separate

configuration menu.

19. A tap on the SERV button

calls up a list of all channels.

A lock symbol is inserted

next to encrypted channels.

What’s also convenient with the

Spaun Sparos 711: A dedicated

column indicates whether a

channel broadcasts in standard

definition or high definition.

20. The PID button opens a

table with all associated PIDs.

21. And a tap on the NIT button

lists all data from the network

information table. The amount

of data can be huge, which is

why a touchscreen device like

the Spaun Sparos 711 is par-

ticularly handy since it allows

easy scrolling.

22. It is possible to call up

the service list with channels

available on the transponder

directly from the main menu.

Simply tap on the quadrant in

the lower right corner of the


you’ll soon get used to gliding

your finger across the screen

until you reach the exact fre-

quency you’re looking for and

than tap to place your marker

right there. This works ab-

solutely perfectly and most

probably you’ll never look

back to older meters with

their rotary knobs.

As thorough testers we’re

always in for surprises, and

with the Spaun Sparos 711

it’s the spectrum mode that

has wowed us with an awe-

some feature: It can show

the live video of the ana-

lysed channel together with

the real-time spectrum. The

way this works is that the live

video is superimposed in a

slightly transparent way over

the spectrum display. With

all this information available

on a single screen usability

of this meter is taken to new

heights. Simply tap on a tran-

sponder and then use the NIT

TV button to call up all NIT

data while at the same time

watching the live video. No

need to enter any reception

parameters whatsoever. Inci-

dentally, if you would like an-

other channel superimposed

over the spectrum display all

you need to do is head back

to the main menu, select the

desired channel and call up

spectrum mode again. If you

then press the NIT TV but-

ton you will be able to see the

channel you have previously

selected in the main menu.

Certain tasks may be facili-

tated by such a procedure, so

it’s reassuring to know that

there’s an easy way to ac-

complish it.

It goes without saying that

the Spaun Sparos 711 sup-

ports constellation diagram

measurements in all operat-

ing modes. This is of particu-

lar importance in the realm of

DVB-C, as it can help enor-

mously in identifying causes

for inferior reception quality.

As expected, quadrants can

be enlarged and the constel-

lation diagram reacts swiftly

and comes with high reso-

lution. Its colour palette is

more than sufficient, a detail

that might appear minor but

which can eventually make or

break the user flow and effi-

ciency of a constellation dia-

gram. All digital modulations

are supported, including DVB-

T2 with shifted constellation.

Many countries have im-

plemented digital terrestrial

television using so-called

single-frequency technology

networks (SFN). This means
