SVAN 979 User Manual - Appendixes
logger file splitting mode:
0 – no splitting
-1 – split after each measurement cycle
15 – split after each full 15 minutes of real time clock
30 – split after each full 30 minutes of real time clock
60 – split after each full hour of the real time
1440 – split at defined times
Six timestamp values of logger file splitting (only if SplitMode is
1440):
-1 – value is inactive
0..1439 – time in minutes (for example, 100 means 1:40 AM)
time in seconds between start of measurement and last
synchronization of real time clock based on GPS signal:
- Value 0FFFFh means that within 30 seconds before the
start of measurement, real-time clock synchronization did
not occur
- The parameter says nothing about synchronizing the
real-time clock before 30 seconds prior to the
measurement start
measurement start time in milliseconds
number of split measurement files (zero means infinity) - the
parameter is important if the duration of the measurement cycle
(IntTimeSec) is set to infinity; for finite measuring cycle times this
parameter is irrelevant (see: RepCycle)
Table B.1.8. Measurement triggering parameters
2Bh = block identifier
0nnh = block length in words
trigger mode:
0 – measurement without triggering
1 – positive slope (Slope +)
2 – negative slope (Slope –)
3 – positive level trigger (Level +)
4 – negative level trigger (Level –)
6 – positive gradient (Grad +)
7 – external pulse
trigger source (parameter relevant only to modes in which triggering
is related to signal level):
0 – triggering RMS/Leq level from the first profile
- Other remaining values
trigger threshold value in 0.01 dB format (parameter relevant only to
modes in which triggering is related to signal level)
trigger gradient value in 0.01 dB/ms format (parameter relevant only
to „Grad+” mode)
trigger time check in 0.1ms format
