with long-term analysis. The

results can either be saved

right to the meter’s internal

memory or onto an external

storage medium in the CSV

file format. As an alternative,

you may opt to save the table

as a bitmap file.

When we tried to save a

table in bitmap format that

was larger than the screen

we were pleasantly surprised

to find that the Spaun Sparos

711 automatically scrolls the

table and then saves an im-

age that is made up of the en-

tire chart. So no matter which

way you save your table, you

can be sure never to miss a

thing – great stuff!

We are truly amazed by

such an open concept, since it

allows users to fully custom-

ise their measurement proto-

cols and to set up automatic

sequences for many small

steps in the process. MS Of-

fice templates, for example,

work just fine for creating

those pre-defined routines.

What’s more, measurement

results can easily be archived

permanently this way without

having to worry about unusu-

al file formats that might be

of no use a few years down

the road.

The Spaun Sparos 711 runs

through the measurement

protocols in almost perfect

fashion. All you need to do is

select the desired transpond-

er list in the main menu and

then call up MEASUREMENT


In an instant, the meter will

begin to measure all tran-

sponders on the list and will

enter all results into a table

– just like it should be. But

it wouldn’t be Spaun if there

weren’t more to it: For ex-

ample, the transponder list

can be a mixed bag with dif-

ferent modulations and still

work perfectly. This comes

in handy if, for instance, a

coax cable carries DVB-C

transponders in the 50 to

900 MHz range and DVB-S/

S2 transponders in the 950 to

2150 MHz range at the same

time. The Spaun Sparos 711

will happily work through one

signal after the other in such

a scenario.

Measured results cannot

only be shown in a table, but

also as a bar diagram, which

includes the frequently used

TILT function that allows you

to perfectly fine-tune a sig-

nal amplifier, among other

things. The Spaun Sparos

711 displays a bar for each

transponder, the colour of

which depends on the signal

level. Red bars indicate sig-

nals that fall below the mini-

mum threshold, orange bars

exceed the upper threshold

level and green bars stand for

transponders whose signal

level is between the two limit

values and therefore in the

optimum range. The thresh-

old levels are pre-set by the

manufacturer and cannot be

edited by users, but Spaun

has selected very meaning-

ful thresholds for individual

modulations that make a lot

of sense.

Working with the measure-

ment protocol function is ex-

tremely user-friendly and fol-

lows a self-explanatory logic

that allows users to achieve

perfect results even without

consulting the manual first.

And there’s another bonus

function that should not be

missed: Users can initiate

a search that only looks for

pre-defined modulations. All

found transponders are again

entered into a list and once

the search is completed they

are measured in a loop. Of

course a transponder list that

has been created this way can

be used for future test runs at

any time, and whenever it is

called up the corresponding
