Scr Carrier Mode; Histogram Display - Kathrein MSK 115/S2 Betriebsanleitung

SCR CARRIER MODE

In order to use the MSK 115/S2 SCR carrier functions, the device must be set to DVB-S1 mode.
For measuring on SCR systems, the carriers can be switched to 1400 MHz.
To switch on the SCR system carrier, fi rst call up the DiSEqC
until the single-cable system can be selected (e.g. ASTRA SCR 4SU, i.e. ASTRA single-cable matrix system
for 4 subscribers). Afterwards, press the > button to send the DiSEqC
carrier on 1400 MHz.
A transponder list will then appear, Press the < or > button until the item „SCR 60 dB" appears. A histogra-
phic diagram will be displayed.

HISTOGRAM DISPLAY

The MSK 115/S2 only activates the carrier at 1400 MHz; if other SCR carriers are switched on through other
devices, the MSK 115/S2 will display these, as seen in the example above.
The plotted line corresponds to a level of 60 dBμV.
OPERATING MENU
The MSK 115/S2 has a histogram display. This can be used
60 dB
in SCR single cable systems to measure up to 8 different
frequencies at the same time.
These frequencies are typically:
SCR1 = 1,284 MHz
SCR2 = 1,400 MHz
SCR3 = 1,516 MHz
SCR4 = 1,632 MHz
SCR5 = 1,748 MHz
SCR6 = 1,864 MHz
SCR7 = 1,980 MHz
SCR8 = 2,096 MHz
Press
60 dB
If the level of some SCR channels is too low to guarantee safe
operation of the system, this logical display will simply show a
"PASS" or "FAIL" for each channel, as in the examples shown
here.
