LOGGER function
By means of the LOGGER function in TV mode, a register of measurements
which are obtained as result of the exploration to find TV channels (analogues and
digitals) over the frequency band that corresponds to the active channel plan is carried
out:
-
Signal level measurement (LVL) for analogue channels or power (PWR)
for digital channels.
-
Audio-Video ratio(A/V) measurement in analogue channels.
-
Carrier-noise ratio (C/N) measurement in analogue channels or MER in
digital channels.
-
Digital channel BER measurement.
-
Symbol rate
These measurements are stored in memory for their later display, printout or
transfer to a PC.
The PROMAX-26 allows users to store up to 50 loggers (or acquisitions) in the
memory, with up to a maximum of 140 analysed channels in each of them.
A screen like the following figure appears when the LOGGER [F4] key is
pressed. On the left, the number of the logger (0 in the example) followed by the time
and date it was acquired (only if the execution of the STORE function) are indicated.
