SAS Monitor and Control Software
Monitor status display
Custom applications suite of software included
with Z2094B
The monitor and software control application consists of three (3)
major components:
–– SAS Self Test
–– SAS Monitor and Event Log
–– System Level SCPI Remote Interface
SAS self test
System self test performs internal diagnostic tests for all main-
frames, modules, and additional instruments. OVP, OCP, isolation
relay, digital port connections, fault/inhibit response, and more
are retested with self test loads installed. All results are reported
and logged for archival reference.
Figure 2. The Status Display is provided as part of the system. Custom displays can
also be created using the SCPI library.
System level SCPI remote interface
(Standard commands for programmable instruments)
The system level SCPI allows all of the SAS modules and
subsystems to be programmed and controlled as a single system
interface using a LAN connection. In addition, it provides a
remote web interface to the system identical to the monitor and
event logging application. The SCPI command set is in confor-
mance with the SCPI Consortium 1999 standard. Details of this
command interface can be found in the “Keysight Z2094B-103
Solar Array Simulator System Programmer’s Reference.” It utilizes
TCP-IP and static addressing for remote communication.
The system supports the interface from NI-VISA, Keysight VISA,
LabVIEW, C++ and C# programming.
Figure 1. Self Test is an independent application that can run with the satellite
connected or disconnected. Coverage is limited when connected to the satellite.
SAS monitor and event log
The SAS Monitor Application is a software suite that provides a
complete configure, control, observe, and troubleshoot software
package for use with the SAS system. The Monitor itself provides
a graphical user interface that allows for easily observing the
status of each of the Keysight E4360A mainframes in a system.
It displays important details about each of the SAS modules,
including its output state, output voltage, and current mode of
operation.
Application specific simulations can be created using the tool
available with the SAS SCPI interface. The interface allows
multiple channels to be configured as groups and controlled
by SAS lists. A series of list elements can emulate an eclipse,
satellite rotation, partial occlusion by an approaching space craft,
string failures, and other operational events.
Details of software applications are available in the following
documents: SAS Monitor User’s Guide Generic; Self Test User’s
Guide; and Keysight SAS Programmer’s Reference.
