Q: Variable voltage 1553 bus output linearity
A: The variable voltage output of the PCI-1553 and all of our other variable voltage boards is not a calibrated, absolute level. The variable voltage function allows the user to attenuate, in terms of a percentage, the maximum output. Furthermore, the voltage output is slightly non-linear at low output levels.
The non-linear output is a function of the commercial 1553 transceiver hybrid and the external load. The output is not calibrated because the output level depends greatly on the external load. The external load is a function of the actual bus setup; the number of stubs and cable length, for example, greatly affect bus loading.

Q: How to view the 1553 Bus with an Oscilloscope.
A: In many cases, a 1553 bus analyzer or bus monitor is perfectly adequate for troubleshooting a 1553 network. However, there are times when you may need to use an oscilloscope to know exactly what is happening on your bus.
The purpose of this Application Note is to provide the basic information to connect an oscilloscope to the 1553 network and to describe the results of using the oscilloscope. This information is not specific to Condor Engineering products, but applies in general to 1553 networks.
This Application Note assumes a basic knowledge of 1553 and usage of oscilloscopes. For information on the MIL-STD-1553 protocol refer to the "MIL-STD-1553 Tutorial" document available from Condor Engineering Inc

Q:Using the BusTools/1553-API with Microsoft Visual Studio .NET 2003
A:The BusTools/1553-API can be used with many platforms and environments. This document describes how to use Microsoft Visual Studio .NET 2003 (C++) to set up a very simple Win32 console application project using the Condor BusTools/1553-API. This enables you to use the Visual Studio .NET 2003 IDE to develop C/C++ programs with the Condor 1553 API. More information on using Microsoft Visual Studio .NET can be found at: http://msdn.microsoft.com/vstudio/using
Note: The Microsoft .NET framework is not supported by Condor APIs. More information on the Microsoft .NET framework can be found at:
