SENSe Subsystem (CATV, K20) R&S FSL
1300.2519.12 6.486 E-11
[
SENSe<1|2>:]ATV:CN:CFRelative:NEXT
This command switches from one frequency range to the next according to the measurement
frequencies defined by the [SENSe<1|2>:]ATV:CN:TABle<1...10>:MFRequencies
command.
T
he numeric suffixes <1|2> are irrelevant.
This command is an event and therefore has no *RST value and no query.
Parameter
(RF–10 MHz) to (RF+10 MHz)
Example
ATV:CN:TABL1:MFR 1,1000,1000
Activates the first row entries for the measurement and sets the center frequency to 1 kHz and
the span to 1 kHz.
ATV:CN: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:CN: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:CN:MEASurement:MODE
This command defines the measurement method for the Carrier–to–Noise Ratio measurement.
The numeric suffixes <1|2> are irrelevant.
Parameter
ISERvice
(In–Service)
While an analog TV signal is present, a gap between two consecutive
channels, where only noise exists, is used to determine the noise power. A
noise marker is placed there, and the noise power is determined.
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.
Example
ATV:CN:MEAS:MODE OSER
Sets the Off–Service measurement method.
Characteristics
RST value: ISER
SCPI: device–specific
Mode
