1.584 RuS-PKU-SSPA

This page describes the Rohde&Schwarz PKU Series SSPA device driver and its device window.

The drivers was tested with the following equipment:

• Model: PKU-100
• SW version: 2.2.0

To allow proper operation the correct band und model has to be selected in the device setup

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 transmit parameters.
• --- Displays meter readings like output power and BUC specific measurements.
• --- 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 device.

• 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.

• band --- Selects the units band:

  • KU (13,75-14,5GHz),
  • DBS (17.2-18,1GHz) or
  • Lower KU Band (12.75-13.25).

• model --- Selects units power class: 400W or 750W.

• startup --- Selects startup behaviour of the SSPA after a power cycle.

• reference --- Selects reference source of the SSPA

• freqCorrection --- Defines the frequency correction factor in %.

• tempWarn --- Defines the temperature warning threshold level.

• tempFlt --- Defines the temperature fault threshold level.

• linearizer --- En- or Disables the units linearizer.

• linearizerMode --- Selects the linearizer band mode.

• predistortion --- En- or Disables the units predistortion.

• powerLimit --- Defines the units power limit (ALC mode).

• powerWarn --- Defines the units power warning limit in W.

• powerFault --- Defines the units power fault limit in W.

• gainLimit --- Defines the units gain limit (Manual Mode)

• gainWarn --- Defines the units gain warning limit in dB.

• gainFault --- Defines the units gain fault limit in dB.

• powerDisplayMode --- Defines the display of gain or attenuation in the parameter section.
