SV 977D User Manual - Appendixes
In the case of RT60 function there are additional codes:
#2,EDT; this function allows you to read the current EDT results.
#2,T20; this function allows you to read the current RT20 results.
#2,T30; this function allows you to read the current RT30 results.
The function’s answer is in the one of the following format:
#2,<type>,0,<status>; when results are not available
#2,<type>,1,<results>; when results are available.
<type> accepts the following values: EDT/T20/T30
<status> is the status of device (0 – no results, 1 – waiting for trigger, 2 – measurement in progress, 3 –
calculations)
<results> is the full list of frequencies with corresponding results in the format:
freq1:value1,freq2:value2,…,freqN:valueN
The exemplary answer:
#2,T30,1,50.0Hz:---,63.0Hz:---,80.0Hz:---,100Hz:0.48s,125Hz:---

A.2.3. Read-out the STIPA results
#2,STI,CP; this command creates new project and returns new project name.
#2,STI,CA; this command creates new area and returns new area name.
#2,STI,CS; this command creates new source and returns new source name. e.g. #2,STI,CS,"S2";
#2,STI,PL; this command returns the project list. e.g. #2,STI,PL,2,”PROJ0001”,”PROJ0002”;
#2,STI,AL; this command returns the area list. e.g. #2,STI,AL,2,”AREA1”,”AREA2”;
#2,STI,SL; this command returns the source list. e.g. #2,STI,SL,2,”S1”,”S2”;
The following list of commands require prior setting of the project, area and source.
#2,STI,NP; this command adds the new point and returns the new point ID.
#2,STI,PC; this command returns the count of the measurement points and list of point IDs, e.g.
#2,STI,PC,n,1,2,3;
#2,STI,MC,p; this command returns the count of measurements at the point p.
#2,STI,AP,p; this command allows you to read and set average flag at the point p.
#2,STI,AM,p,m; this command allows you to read and set average flag for the m measurement at the point p.
#2,STI,DP,p; this command deletes the point p.
#2,STI,DM,p,m; this command deleted the measurement m at the point p.
#2,STI,MR,p,m,mrn; this command allows you to read the results of the m measurement at the point p.
#2,STI,FR,p,m,frn; this command allows you to read the modulation results of the m measurement at the
point p.
#2,STI,SN; this command allows you to read and write Ambient Noise parameters. e.g.
#2,STI,SN,enabled,90.0,91.0,...,95.0;
p: 0..PointCount-1
m: 0..MeasurementCount-1
mrn: STI,LAQ,LCQ,LAS,STM,FLG
