HDR-108/HDR-104/HDR-102 Diversity Receivers
MANUAL V9.8 122
In this field, the Signal of Noise Ratio value of the received signal,
where w is the number of the demodulator (from 1 to 8 for diversity
mode), is displayed in dB. (reading parameter)
 [Tw] MER:
In this field, the Modulation Error value of the received signal, where
w is the number of the demodulator (from 1 to 8 for diversity mode),
is displayed in dB. (reading parameter)
 [Tw] State:
This option allows enabling or disabling each of the IF inputs of the
device. When the Enable option is selected in an IF input, this input
supplies power to the down converter connected to it. (eligible
parameter)
The available options are:

Enable

Disable
 [Tw] IF Cable Type:
In this field, if a cable is used from the Receiver device to the down
converter device (8 available) the type of the cable must be specified.
The possible types of cables are RG-142, RG-58, RG-214, LMR-400,
CEFLEX 1/2, LDF450A 1/2, BELDEN H125, BELDEN PRG11, LMR200
and Andrew FSJ2. (eligible parameter)
 [Tw] IF Cable Length:
In this field, if a cable is used from the Receiver device to the down
converter device, the length of the cable must be specified. The
maximum length available is 150 meters (editable parameter)
 Diversity:
The available options are:
-
Mobile (MRC[1] technique)
- Fixed (Switching technique)
[1] MRC limitations to take into account:
-
MRC doesn’t work when LO is superior to the RF
- MRC doesn’t work if the IF is lower than 400 MHz
In both cases, the unit changes automatically to “Fixed” mode and a
flicker “f” appears on DVB-T main screen of Receiver unit.
ISDB-T modulation always works in fixed mode.
When editable parameters are being set in the Web Server and new
values are being introduced, the text remains in RED until the enter
button is pressed. When the enter button is pressed, the new values
are saved and the text will appear in BLACK. It is necessary to press
the enter button to keep and save the new values on the screen.
