This page describes the device driver and the device window for the CPI VZU TWT amplifiers. The driver has been tested with the following model: VZU6995F (via CIM VJW2740092)
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)
--- 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). While communicating via CIM the first HPA's address is 65 (A) and the second HPA's address is 66 (B). |
| 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 . |
