Scan
This function can be called also using the dedicated DOWN&SEL buttons
pushed together. It allows making a scan over a desired frequency group.
MPR30-IEM manages up to 2400 custom frequencies organized in 40 groups
of 60 channels each. This extreme flexibility makes the scan function very
flexible.
Once started a scan operation the receiver asks for group
to be used*.
Then it prompts to turn off all
transmitters.
Then finally
start the scan!
After few seconds,
scan results are
displayed on a chart.
Pushing simultaneously
UP and DOWN button,
the results can be also displayed sorted by level, making easier to pick up the best one.
(*)As per Wisycom standard, group 00 and group 01 or 09 are special; respectively the “center
frequency” (474,482/… MHz) and the intergap frequency (i.e. 470/478/486/… MHz). A scan on
group 00 will reveal in few seconds the overall DVB-T occupation on the area, while a scan on
group 01 will give possible working frequency, usable also in presence of strong DVB-T signal
(sort to speak working in the band-guard of 2 digital television channels).
