SVAN 977C User Manual - Appendixes
VLM mode:
<result1> - Peak result, depending on the value of BufferP[3] (cf. Table B.1.13)
<result2> - P-P result, depending on the value of BufferP[3] (cf. Table B.1.13)
<result3> - Max result, depending on the value of BufferP[3] (cf. Table B.1.13)
<result4> - RMS result, depending on the value of BufferP[3] (cf. Table B.1.13)
(5) RPM result if the corresponding LOGGER position was active (RPM_On in Table B.1.6) written as two
words:
<wordL><wordH>
WYK_OKR_OBR = 64
m = ((wordH > & 0x007f)<<16) | ((wordL & 0x7fff)<<1)
w = ((wordH >> 8) & 0x007f)-23-WYK_OKR_OBR
d = m*2
w
RPS = 1/d
RPM = 60/d
(6) results of 1/x OCTAVE analysis if 1/x OCTAVE analysis was selected as the measurement function and
the LOGGER was active (SpectrumBuff in Table B.1.6); the sequence of words is written:
<Octave[1]> <Octave[2]> ... <Octave[Noct+NTot]>
where:
Octave[i] - the result of 1/x OCTAVE analysis (*100 dB);
i = 1..NOct+NTot (cf. Table B.1.17)
(7) results of FFT analysis if FFT analysis was selected as the measurement function and the LOGGER
was active (SpectrumBuff in Table B.1.6); the sequence of words is written:
<FFT[0]> <FFT[2]> ... <FFT[N+T]>
where:
FFT[i] - the result of FFT analysis (*100 dB);
i = 0..(N+T)
(cf. Table B.1.19)
B.2.1.2. Record with the state of the markers
The record with the state of the markers consists of one word:
<0x8nnn>
in which 12 bits nnn denote the state of the markers:
b11 = state of #12 marker
b10 = state of #11 marker
...
b1 = state of #2 marker
b0 = state of #1 marker
