It can be seen that the first 10 bytes translate into ASCII and look
like the simple beginning of a query response. This is followed by
the string "#9000000430". This is the beginning of a binary block
where 9 ASCII integers are used to give the length of the block
(430 bytes). The waveform itself starts immediately after this
byte number 21 (the first byte is byte 0).
Deciphering the waveform descriptor can be done with the aid of
the template (see Appendix B). It states that the first object is
DESCRIPTOR NAME which is a string of 16 characters with the
value WAVED-ESC and this is what we see. At byte 16 relative to
the beginning of the descriptor (or byte 37 above) we find the next
string, the TEMPLATE_NAME with the value LECROY_I_I.
Several other parameters follow. We can easily recognize the IN-
