The data stored in the data block and extra data sent vary by memory type:
RTA, RTA LOW
data block stores 120 1/12 octave integer RTA magnitude value data points in 10 * dB.
No data stored in extra data.
FREQRESP
data block stores 120 magnitude value data points in 10 * dB.
No data stored in extra data.
IMP
data block stores 120 impedance value data points in 10 * Ohms.
No data stored in extra data.
ETC
data block stores 120 magnitude value data points in 10 * dB.
First extra field stores the window index number, corresponding to the time window
selected. 0 ==
15 ms, etc.
Second extra field stores the octave band filter in effect:
no filter 0
static char pm ec14[] = {" 31"}; 1
static char pm ec15[] = {" 63"}; 2
static char pm ec16[] = {" 125"}; 3
static char pm ec17[] = {" 250"}; 4
static char pm ec18[] = {" 500"}; 5
static char pm ec19[] = {"1000"}; 6
static char pm ec20[] = {"2000"}; 7
static char pm ec21[] = {"4000"}; 8
static char pm ec22[] = {"8000"}; 9
NOISE
data block stores 120 magnitude value data points in 10 * dB.
First extra field holds time index, 0 = min time.
Second extra field holds input source, 0 = MicL
Third extra field holds filter,
None 0
A 1
B 2
C 3
