found, the scan stops and a
measurement is initiated. In
addition, the meter gives out
the following parameters for
each active frequency, de-
pending on the actual signal
type: RF, signal level, MER
and BER for digital signals,
and RF video signal level,
RF audio signal level as well
as SNR for analog channels.
What’s more, you don’t only
get a precise figure, but also
an info bar!
During our test the display
did not only impress us with
its clearly structured display
layout, but also with abso-
lutely flawless readability
under all circumstances. So
it’s easy to see why we could
hardly wait to have a close
look at the signal of our local
DVB-C provider. As it turns

It didn’t take long until the
first measurement results
popped up on our meter’s
display, and we were amazed
by the ease of use and smart
simplicity of the HD-CM+.
As always with signal me-
ters that we test, we need
to find out if the indicated
values can be categorised
as rough estimates (read:
unreliable) or correct results

nected a second meter from
another manufacturer and
discovered that both devic-
es showed almost identical
results. The conclusion that
can be drawn is that Horizon
has made a point of equip-

meter with an excellent tun-
