For example, there are many ways of setting the time base of the
instrument to 5 ~tsec/div:
TDIV 5E-6
TDIV 5 US
TDIV 5000 NS
TDIV 5000E-3 US
Exponential notation, without any
suffix.
Suffix multiplier "U" for 1E-6,
with the (optional) suffix "S" for
seconds.
This data type enables the transfer of a (long) string of characters
as a single parameter. String data are formed by simply enclosing
any sequence of ASCII characters between simple or double
quotes.
MESSAGE ’Connect probe to point J3’
The instrument displays this message in the Message field above
the grid.
These are binary data values coded in hexadecimal ASCII, i.e.
4-bit nibbles are translated into the digits 0,...9, A .... F and trans-
mitted as ASCII characters. They are only used for the transfer of
waveforms (command "WAVEFORM") and of the instrument
configuration (command "PANEL_SETUP")
The instrument sends a response message to the controller, as an
answer to a query. The format of such messages is the same as that
of program messages, i.e. individual responses in the format of
commands, separated by semicolons <;> and ended by a termina-
tor. They can be sent back to the instrument in the form in which
they are received, and will be accepted as valid commands. In
GPIB response messages, the <NL> <EOI> terminator is always
used.
For example, if the controller sends the program message:
TIME_DIV? ;TRIG_MODE NORM;C 1 :COUPLING? (terminator
not shown)
