A.2.4. Examples
The exemplary averaged results of the instrument’s response after sending to it the following sequence
of characters: #2,a,1; coming from the first profile are given below:
a) for the case of the SLM mode:
#2,a,1,v1,V0,T39,P125.4,M107.0,N20.6,S81.7,R102.1,U118.0,B(4)112.1,I(480)102.1,Y103.9,Z105.4,
L(01)107.9,L(10)107.6,L(20)107.2,L(30)102.8,L(40)99.0,L(50)96.7,L(60)82.5,L(70)54.5,L(80)20.9,
L(90)20.4,g90.8,h94.4,C1,F2017-11-24,G16:26:03,O?,K?;
b) and for the case of the VLM mode:
#2,a,1,v0,V0,T1,P93.9,Q99.7,M45.6,R45.6,H85.0,C1,F2017-11-24,G17:00:01;
Note: The presented above order of the measurement results sent out by the instrument does not
depend on the sequence of the characters sent to the unit.
Example: After sending to the instrument the string:
#2,i,1,T?,R?,V?,P?,L?;
the unit sends out the instantaneous results of measurement coming from the first profile in predefined,
described above, order:
#2,i,1,V0,T39,P125.4,R102.1,L(01)107.9,L(10)107.6,L(20)107.2,L(30)102.8,L(40)99.0,L(50)96.7,
L(60)82.5,L(70)54.5,L(80)20.9,L(90)20.4;
Note: All bytes of that transmission are ASCII characters.
17.9 A.3. FUNCTION #3 – READ OUT OF THE MEASUREMENT RESULTS IN 1/X OCTAVE OR FFT
MODE
#3 function enables one to read out the current measurement results in 1/x OCTAVE or FFT mode.
#3 function format is defined as follows:
#3,A; - averaged spectrum
#3,I; - instantaneous spectrum
#3,M; - max spectrum
#3,N; - min spectrum
The device responds, sending the last measured spectrum (when the instrument is in STOP state) or currently
measured spectrum (when the instrument is in RUN state) in the following format:
#3;
<Status Byte>
<LSB of the transmission counter> <MSB of the transmission counter>
<LSB data byte> <MSB data byte>
(...)
<LSB data byte> <MSB data byte>
Status Byte gives the information about the current state of the instrument.
