TXT
One file contains waveform samples for one M8190A channel as normalized values (-
1.0 .. +1.0) and optionally marker values separated by ‘,’ or ‘;’ or ‘\t’. Not given
marker values are just set to 0. Space ‘ ‘ and ‘\t’ are ignored. Line end can be \r or
\r\n. The waveform samples can be imported to any of the two M8190A channels.
Example (US locale)
0.7,0,1
0.9,1
Example (German locale):
0,7;0;1
0,9;1
In German locale it is recommended (but not required) to use ‘;’ or ‘\t’ as separator.
But it must then be ensured that the double really has a decimal point (‘,’) or there is
some space inserted to ensure correct parsing:
0,7,0,1
0 ,0,1
TXT14
One file contains waveform samples and marker bits for one channel. Each line
consists of a 14 digit DAC value + 2 Marker values.

BIN
One file contains waveform samples and marker bits for one channel. Thevalues are
binary int16 values (in little endian byte order) directly in M8190A 14 bit precision
mode format:

In 12 bit mode DB1 and DB0 are simply ignored.
IQBIN
One file contains I/Q sample pairs and two markers (in little endian byte order)
directly in M8190A x12, x24 and x48 interpolated mode format, see description in
Waveform Data Format in Interpolated Mode. In x3 interpolated mode I0 and Q0 are
simply ignored.
