Optional hardware
HE 310
Option 2: The step to a high-end return path monitoring system—combination with field device VAROS 107
The result: traditional AND quality measurements in the return channel
1 VAROS 107 measurement possibilities
Cluster selective:
Sum signal and cluster selective:
2 HE 310 with SW 024 (optional)
The SW 024 allows for an optional extension to up to 24 upstream clusters: switching of field devices on one cluster; creation of a sum signal out of all 24 clusters. Thus measurements can be performed cluster selective or with the sum signal.
Interaction with VAROS 107
HE 310: standalone mode usable as real-time spectrum analyzer with max-hold function (sum signal and cluster selective).
3 HFC
Hybrid Fiber Coax Network: Optical and coax cable distribution network for downstream and upstream from the headend to the subscriber.
4 Transfer of measurement data to …
the head-end equipment
In the headend these data streams can be multiplexed in existing DVB-C channels as a separate data service.
Real-time spectrum analyzer
The heart of the HE 310 is a real-time spectrum analyzer. Typical errors are reliably detected like e.g. an increased noise floor, short-term ingress interferers or a TILT in the upstream frequency range.
The Max-Hold function in real-time guarantees for a detection of even shortest ingress events.
Also in the return channel: Quality is what counts
In addition standard (and well know from the downstream) RF measurement parameters such as MER and BER or constellation diagram can be gathered and transmitted back to the field devices VAROS 107.
For this purpose test signals transmitted by the field devices are highly precisely measured by the HE 310.
Never bevor amplifier line-up has been so easy
No matter if attached to the house or a line amplifier—The line-up toolbox guides you through leveling and equalizing the return channel—safe and easy.
Still standard in the return channel: Wobbeling (frequency response measurement)
The frequency response measurement is done without affecting active modem connections. The zoom function helps when evaluating details.
The protocol function is only one push of a button away:
One push of a button is enough to execute all measurements possible with the system and to store the results as a protocol in XML format. Also for the protocol generation no previous knowledge is necessary.
Some user editable control elements allow for a fast assignment of a protocol to the measurement location, a customer, a field technician, a measurement situation and so on.
