R&S EU4200C Configuring with the R&S ZS 4200
6174.8456.02-01 3.20
DHCP Enabled
This parameter is used to enable dynamic host configuration (DHCP). If
enabled, the radio uses DHCP and can learn an IP address from a DHCP
server installed in the network.
Note:
DHCP is supported in IPv4 network only. It is not possible to enable
DHCP while IPv6 is being used.
RX Hostname
RX Hostname is assigned to the RX module. Characters and other naming
conventions must comply with the RFC 952 rules. The parameter is
included in the initial DHCP message sent from the radio to the DHCP
server. If the DHCP server is configured accordingly, this information can
be used to inform a DNS server about a potential change in the mapping of
the IP address to hostname.
NTP Server
If this parameter is set to a valid IP address or a fully qualified domain
name (FQDN) of an NTP server, the radio starts to periodically synchronize
time with the NTP server.
Note that dynamic delay compensation in multi-carrier offset operation (see
ED137B-1) may require the use of the NTP. For such applications, it may
take some time until NTP time synchronization is sufficiently accurate.
STD Enabled
This parameter enables or disables the simultaneous transmission
detection (STD) functionality of the radio (see chapter 3.15 Simultaneous
Transmission Detection (STD)). A valid option key "Simultaneous
Transmission Detection" is required.
STD User Out Enabled
This parameter enables signalling of detected simultaneous transmission
events via the User Out port (pin X11.6). If enabled, the signalling is active
as long as the simultaneous transmission lasts.
STD Outer Band
Check
This parameter is disabled by default and should be only enabled if the
device operates in a multi-carrier offset operation environment (CLIMAX). If
enabled, the implemented simultaneous transmission detection algorithm
will raise an alarm if it detects both a signal at a Climax offset and a signal
at the nominal channel frequency. If disabled, the algorithm will only raise
an alarm if it detects two signals around the nominal channel frequency.
STD CCIR Threshold
This parameter is used to configure the carrier-to-carrier interference range
(CCIR) Threshold. The radio signals double transmissions to the user if the
CCIR value which is internally measured by the algorithm is below the
configured CCIR threshold.
STD Event Counter
This parameter is a 32bit counter which is incremented by 1 whenever a
double transmission occurs. The counter can be configured for a specific
(initial) value. If the maximum counter value is reached, the value is reset
to 0. The counter is set to 0 upon restart of the radio.
STD Overlap Time
Threshold
This parameter defines the minimum overlap time of a simultaneous
transmission necessary to generate an STD event.
The overlap time threshold can be set to 800 ms, 1200 ms, 1600 ms and
2000 ms. The default value is 800 ms.
The user has the possibility to increase the overlap time threshold, to adapt
the function to every operational condition.
