stream-speed-test

Commandline utility for testing streaming performance

Building

• Install libtiepie, see https://www.tiepie.com/libtiepie-sdk
• Compile the application using the GCC compiler by running make (or mingw32-make on Windows)

Command line options

• -b <resolution in bits> - Resolution for measurement. (default: highest possible)
• -c <number of channels> - Number of active channels for measurement. (default: all)
• -f <sample frequency - Sample frequency in Hz. (default: 10kHz)
• -l <record length> - Record length in Samples. (default: 5000)
• -d <duration> - Duration of the measurement in seconds. (default: 60)
• -s <serial number> - Open instrument with specified serial number. (default: auto detect)
• -r - When specified the raw data to floating point data conversion is disabled.

Example

• ./streamspeedtest -b 14 -c 1 -f 10000000 -l 5000000 -d 30 -r - Performs a streaming measurement for 30 seconds sampling at 10 MHz @ 14 bit, raw data is passed in 5 MS blocks to this test application.
• ./streamspeedtest -b 8 -c 4 -f 100e6 -l 16777216 -d 300 -r - Performs a streaming measurement for 5 minutes sampling at 100 MHz @ 8 bit on 4 channels, raw data is passed in 16 MiS blocks to this test application.
