Best practice is always:
For power up:
1.
Start by powering up the analyzer and wait for it to start sweeping.
2.
If using an MS2090A with the MA25101A PCIe card, set the following:
•
IQ Capture Mode: Streaming
•
Output Port: Data Out
•
Data Out Format: PCIe
3.
Turn on the PC and launch the IQ Acquisition Tool.
For power down:
Turn off the PC, then turn off the analyzer.
Resource Management
When doing large bandwidth captures, you must make all resources available on the PC. The system bus is
fully utilized during the PCIe data transfer. If you play a game, browse the Internet, or edit a document, the
data stream will be interrupted and the transfer will stop.
Besides user programs, it is also necessary to limit system services and background programs running on the
PC. These can also periodically use system resources and interfere with data transfer. IQ Acquisition Tool
must write data at near the limit of the hard drive write speed. For example, if virus protection software is
checking this file for viruses during file writing, the process will be interrupted. IQ Acquisition Tool provides
means to disable many system services that are not necessary to the PC when using this software. It is highly
recommended that you use these tools to limit other background applications. Refer to
