Instrument Functions: A - L
A definite length block of data starts with an ASCII header that begins with # and
indicates how many additional data points are following in the block. Suppose the header
is #512320:
•The first digit in the header (5) tells you how many additional digits/bytes there are in
the header.
•The 12320 means that 12,320 data bytes follow the header.
•Divide this number of bytes by your selected data format bytes/point, either 8 (for real
64), or 4 (for real 32). In this example, if you are using real 64 then there are 1540 data
points in the block.
State Saved: Saved in Instrument State.
Factory Preset: Survives Preset but not power cycle. Powers up in ASCII format.
