2 Product Description
The smartmeter T20 is a compact digital meter used to check signals and
locate errors on aerial systems to easily and quickly align outdoor DVB-T
aerials and to identify the optimum location for DVB-T room aerials.
The smartmeter T20 gives several measured values for the selected station, e.g. signal strength and signal quality as numerical values (in %) and
as bar graphs, signal-to-noise ratio (SNR), Modulation Error Ratio (MER)
and bit error rate (pre BER, post BER). Additionally, the user can check the
TV picture quality on the 8.9 cm-wide high-resolution LCD display.
