USER'S MANUAL. PROLINK-4
When you select the NTUN (continuous tuning using a narrow detection filter)
and BTUN (continuous tuning using a broad detection filter) options the screen displays
a window showing the frequency deviation of the sound carrier, this is variable
between 4.00 MHz and 9.00 MHz. To define it turn the rotary selector [4] to the desired
frequency deviation and press to validate.
When the LV function is selected, the speaker of the PROLINK-4 permits a
tone whose frequency depends on the level of the signal received. This is very useful
when installing antennas, since the user can locate the peak signal without having to
look continually at the monitor of the level meter.
When the NICAM option is selected, it is possible to measure the Bit Error Rate
of the modulation. To obtain this measurement, from the TV operating mode, level
measurement, press key
measurement information displayed on the screen (name assigned to memory, power
supply to external
frequency/channel). In the position relative to the type of Sound will appear the
information about the type of NICAM according to:
Type = NICAM type:
"--": no NICAM is detected
"du": dual NICAM
"st": stereo NICAM
"mo" mono NICAM
Error = indication of the bit error rate:
"E ↓":
error rate < 1e-5
"E5": 1e-5 < error rate < 1e-4
"E4": 1e-4 < error rate < 1e-3
"E3": 1e-3 < error rate < 2.7 e-3
"E ↑":
error rate > 2.7 e-3
Therefore, for example, the indication Sound: duE↓ has to be interpreted as
NICAM sound is selected, the detected NICAM is dual and the error rate is below
1 e-5.
4.12 Measurement Configuration Memories
To facilitate measurement, the PROLINK-4 is able to store up to 99
configurations in an internal memory. In this way, it is possible to select the most
common transmissions in a work area with their corresponding configurations quickly
and easily.
