1.445 Newtec-AZ110

This page describes the device driver and the device window for the Newtec Azimuth AZ110 DVB Modulator. The driver accesses the device via SNMP.

Device window pages

The following table shows which device window pages are available with this individual device type. Tool-bar functions not mentioned here are described at the general description of device windows .

• --- The IF parameters (frequency, level, etc.) and some global settings.
• --- The modulator settings.
• --- The TX interface settings.
• --- The DVB-S2 specific parameters
• --- The faults page.
• --- The device info page.
• --- The maintenance page. The configuration parameters described below are set at this page.

Configuration parameters

At the maintenance page of the device window there are a couple of configuration parameters which must be set to make the software talk to the AZ110.

• parameter --- description

• address --- The SNMP address specification for the device. The full address specification consists of the following fields:aaa.bbb.ccc.ddd:pppp read-community write-community

  • aaa.bbb.ccc.ddd --- The IP address of the device in 'dotted quad' notation. This field is mandatory.
  • pppp --- The IP port number where the device accepts SNMP requests. The port number may be omitted, the driver uses the standard port 161 in this case.
  • read-community --- The SNMP read community name. This must match the read community expected by the device.
  • write-community --- The SNMP write community name. This must match the write community expected by the device. The write community name may be omitted, the driver uses the read community name for both, read and write in this case. If both community names are missing, the driver uses 'public' as a default for read and write community.

• amplitudeEQ --- You can set the modulator's amplitude slope equalizer with this parameter (-7 .. +7)

• gainControlMode --- Configures the Gain Control Mode to MGC or AGC

• outputLevelPlan --- Configures the Gain Control Strategy to CONSTANT PWR or CONSTANT RIM.

• levelOffset --- Permits to tweak the output level display by applying an offset. (dB)

• minOutputLevel --- Specifies the minimum value of the output level which can be set with the software. Please note, that this value must be adapted to each individual AZ110 unit to make the driver work properly.

• maxOutputLevel --- Specifies the maximum value of the output level which can be set with the software. Please note, that this value must be adapted to each individual AZ110 unit to make the driver work properly.

• monitorOutput --- Select if the monitor output should also on or follows the tx signal

• ratePriority --- Defines if the symbol rate sets the interface data rate or vice versa.

• extLoFreq --- Lets you apply a frequency offset to the tx frequency parameter.

• extLoPolarity --- Set this to NRM if the RF frequency is above the LO, set it to INV if the RF frequency is below the LO.

• readBackDelay --- Defines the delay the driver uses when it reads back parameters recently commanded. The delay is initialized at a proved preset value which should not be changed under normal circumstances.
