SENSe:ATV:CSO Subsystem (CATV, K20)
The SENSe:ATV:CSO subsystem contains commands for the Carrier–to–Second Order Beat Ratio
(CSO) measurement setup.
Commands of the SENSe:ATV:CSO Subsystem
– [SENSe<1|2>:]ATV:CSO:CFRelative:NEXT
– [SENSe<1|2>:]ATV:CSO:MEASurement:MODE
– [SENSe<1|2>:]ATV:CSO:POWer:NCORrection
– [SENSe<1|2>:]ATV:CSO:POWer:REFerence:CHANnel:MANual
– [SENSe<1|2>:]ATV:CSO:POWer:REFerence:MANual
– [SENSe<1|2>:]ATV:CSO:POWer:REFerence:MODE
– [SENSe<1|2>:]ATV:CSO:TABle<1...10>:MFRequencies
[SENSe<1|2>:]ATV:CSO:CFRelative:NEXT
This command switches from one frequency range to the next according to the measurement
frequencies defined by the [SENSe<1|2>:]ATV:CSO:TABle<1...10>:MFRequencies
command.
The numeric suffixes <1|2> are irrelevant.
This command is an event and therefore has no *RST value and no query.
Example
ATV:CSO:TABL1:MFR 1,–1000,1000
Activates the entries of the first table row for the measurement and sets the center frequency to
–1 kHz and the span to 1 kHz.
ATV:CSO:TABL2:MFR 1,–2000,2000
Activates the second row entries for the measurement and sets the center frequency to –2 kHz
and the span to 2 kHz.
ATV:CSO:CFR:NEXT
Switches from the frequency range defined in table row 1 to 2.
Characteristics
RST value: –
SCPI: device–specific
Mode
CATV
[SENSe<1|2>:]ATV:CSO:MEASurement:MODE
This command defines the measurement method for the Carrier–to–Second Order Beat Ratio
measurement.
The numeric suffixes <1|2> are irrelevant.
Parameter
OSERvice
(Off–Service)
The current measurement channel is switched off by the provider. In this
channel, a noise marker is placed, and the noise power is determined.
QLINe
(Quiet Line)
While an analog TV signal is present, the carrier–to–noise ratio is
measured using the so–called "Quiet Line''. The measurement is fully
automated.
