Using SRTM

SRTM (System Response Time Measurement) is an RTAPI timer latency measurement tool that measures timer latency observed by an application. There are two supplied versions: one for the Windows environment (srtm.exe), the other for an RTSS environment (srtm.rtss).

Usage

srtm [/?] [/h] [/s] [/1] [/f] [/m sharedmemoryname] seconds_to_sample

Parameters

/h

Display histogram (in addition to summary)

NOTE: The histogram in the Windows version (srtm.exe) may not match the maximum latency value. This is due to Windows being non-deterministic.

/s

Turn on sound (square wave driven by timer)

/1

Use a 10 MS timer period (default is 1 MS)

/f

Use fastest available timer (1MS or better)

/m sharedmemoryname

Use shared memory (MUST be 4024 bytes)

/n num

Multiple SRTM instances aware, where num is the total number of instances

/?
