L(nn) value L of the nn statistics (ccc
– the value in dB);
C PTC result (ccc

c PTP result (ccc
– the value in %);
l ULT result (ccc
– value in seconds);
W TWA result (ccc
– the value in dB);
w PrTWA result (ccc

The exemplary results of the instrument’s response after sending to it the following sequence of characters:
#2,1; coming from the first profile are given below:
a) for the case of the SLM mode:
#2,1,x17/03/2014,t13:44:28,v0,V0,T10,P79.97,M52.92,N38.50,S46.35,R43.91,U53.91,B(1)43.91,I(480)43.

0.00,L(80)39.50,L(90)39.00,g?,G?,k?,s?;
b) and for the case of the SEM mode:
#2,1,x17/03/2014,t13:48:36,v0,V0,T7,P124.39,M99.26,N41.54,S42.05,D0,d389,p389,A85.86,R85.86,U94.

Note: The presented above order of the measurement results sent out by the instrument does not
depend about the characters sent to the unit.
Example: After sending to the instrument the string:
#2,1,T?,R?,V?,P?,L?;
the unit sends out the results of measurement coming from the first profile in predefined, described above,
order:
#2,1,V0,T1,P65.80,R43.99,L(01)52.00,L(10)51.10,L(20)46.10,L(30)44.10,L(40)38.60,L(50)38.10,L(60)37.6
0,L(70)37.10,L(80)36.60,L(90)36.10;
Read-out the RT60 results
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
