OUT OF MEASUREMENT RESULTS IN

CTAVE AND
1/3 O
CTAVE
MODE
#3 function enables one to read out the current measurement results in 1/1 OCTAVE or 1/3 OCTAVE
modes.
#3 function format is defined as follows:
#3; - displayed spectrum
#3,A; - averaged spectrum
#3,I; - instantaneous spectrum
#3,M; - max spectrum
#3,N; - min spectrum
#3,P; - peak 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>
<data byte> (...) <data byte>
Status Byte gives the information about the current state of the instrument.
D7 D6 D5 D4 D3 D2 D1 D0
where:
D7 = 0 means that "overload does not happen",
= 1
means that “overload appeared”,
D5 = 0 means that "spectrum is not averaged ",
= 1 means that "spectrum is averaged ",
D4 = 0 the instantaneous current result (RUN State),
= 1 the final result (STOP State),
D3 = 1 results in 1/3 OCTAVE mode,
D2 = 1 results in 1/1 OCTAVE mode,
D6, D1, D0 reserved bits.
Note:
The measurement result is coded in binary form as dB•100 (e.g. 34.5 dB is sent as
binary number 3450).

#4 function enables the user to read-out the data file from the internal Flash-Disk or RAM memory.
The data file formats are given in Appendix B.
#4 function formats are defined as follows:
#4,0,\; file containing the catalogue,
#4,0,?; count of the files,
#4,0,index,count; part of the file containing the catalogue,
