The example waveform file contains 436 (0x1b4) bytes before
the
#
sign in the
EMPTYTAG
; the hex address of the
#
sign is
0x1b5
. The
{WAVEFORM}
starts at
0x4000
. The
EMPTYTAG
con-
tains
15946
blanks and has a length of (15946+1) bytes.
Usage:
Setting only
{LEVEL OFFS: RMSOffset_dB,PeakOffset_dB}
(recommended for waveforms)
The tag determines the level of the ARB signal in the waveform file. The offset levels
define the offset of RMS and peak value relative to the 16-bit full scale modulation
(-32767 to + 32767) = 0 dB.
Setting parameters:
RMSOffset_dB
Defines the RMS level offset of the signal relative to full scale
ARB signal in the
WAVEFORM
tag. The offset is defined in ASCII
float format. The value is always positive.
A 3 dB value indicates that the RMS level of the signal is 3 dBs
below the full scale.
full scale = max. amplitude of vector of I/Q samples = |S
IQ
|max =
sqrt(I
2
+Q
2
)max = 0 dB
