--- Contains the controllable parameters of the device.

--- The maintenance page. The configuration parameters described below are set at this page.This page describes the device driver and the device window for the HP-Synthesizer-SCPI device. This device permits to control the frequency, power level and output on/off settings of a HP signal synthesizer. It leaves all other parameters (e.g. modulation) untouched. These may be set at the device's font panel as required.
The driver has been tested with a HP 8648C synthesizer, however it should be usable with all HP/Agilent/Keysight synthesizers which can be controlled over the GPIB using the SCPI language.
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 .

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.

| address | Enter the GPIB address of the powermeter here (0..31) |
Uncalibrated fault
The device driver shows all faults reported by the synthesizer in one common fault flag called "Uncalibrated". This includes beside the calibration fault reported by the device also output power over/underload faults, the power up temperature warning and a pending power up selftest fault condition.
GPIB Interface setup
This device is operated through a GPIB (HPIB) interface. The sat-nms software actually supports two types of GPIB interfaces: The ENET100 by National Instruments and the Prologix Ethernet to GPIB interface. As the first one is no longer available, new installations should use the Prologix interface.
When configuring the sat-nms software for GPIB devices, type and parameters of the GPIB interface are set as the interface name, "GPIB" is selected as communication protocol. With a Prologix interface, the interface name is something like "PRLX:10.0.0.1", where PRLX selects the Prologix and 10.0.0.1 is an example for the IP address of the interface. With a ENET100 interface (supported for compatibility reasons), the interface name is "ENET:0" for the first interface, "ENET:1" for the second one.
Multiple devices can be operated a the same GPIB, these devices have to be configured all at the same interface. Configuring two or more GPIB interfaces with the same index ot IP address will cause communication faults and misconfigured devices.
