This page describes the device driver and the device window for the CPI Klystron amplifiers Generation 3.
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 Klystron 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 |
| lowLimitAlarm | The low output power alarm trip point. |
| highLimitAlarm | The high output power alarm trip point. |
| lowLimitFault | The low output power fault trip point. |
| highLimitFault | The high output power fault trip point. |
| Serial | Remember to set the line parameters for the serial interface. of the HPA is 9600,E,7,1 . |
| logGainChanges | Defines if gain changes should be written in the event log database. Can automatically be adjusted by logLevelEnabledId within Uplink Power Control |
Serial Interface
The standard configuration is RS-422. To configure RS-232 use the jumpers described in the user manual of the Klystron Chapter 3.
You can configure the line setting on the front panel.
Channel Changer
If the Klystron is equipped with an channel changer you have to configure the number of channels on the front panel of the HPA. Then the M&C system is able to detect this via the ID/Version Query and the driver will enable the channel field. If the Klystron is not equipped with an channel changer, set the number of channels on the front panel to 0 and the driver will not allow to select a channel.
