This page describes the device driver and the device window for the CPI TWT amplifiers.
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 operational parameters (BEAM-ON/STANDBY, RF ON/OFF)
--- Displays meter readings like output power and TWT 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 Amplifier.
| parameter | description |
|---|---|
| address | The device address (decimal). The factory default is 48 |
| checkLimits | Turns the amplifier's built in power limit check off or on. When turned on, the amplifier generates a fault if the output power is outside the limits set below. |
| lowLimit | The low output power limit. |
| highLimit | The high output power limit. |
| Serial | Remember to set the line parameters for the serial interface connected to the TWTA. The factory default of the HPA is 9600,E,7,1 . |
| helixAdvWarning | Sets the advanced helix current warning level. Not monitored if 0 |
| logGainChanges | Defines if gain changes should be written in the event log database. Can automatically be adjusted by logLevelEnabledId within Uplink Power Control |
| deviceComment | An optional text entered here appears as an addition to the tooltip which is shown while the mouse is placed over a device icon in the GUI. The "\n" character sequence is translated into a newline character, splitting the text into multiple lines. |
