Command Syntax
2–4
TDS Family Oscilloscope Programmer Manual
H You can precede any command with white space characters. White space
characters include any combination of the ASCII control characters 00
through 09 and 0B through 20 hexadecimal (0 through 9 and 11 through 32
decimal).
H The digitizing oscilloscope ignores commands consisting of any combina-
tion of white space characters and line feeds.
You can abbreviate many digitizing oscilloscope commands. Each command
listing in the Commands section shows the minimum acceptable abbreviations in
capitals. For example, you can enter the command $"% simply as
or !$.
NOTE. Keep in mind that abbreviation rules change over time as new TDS
models get introduced. Thus, for the most robust code, use the full spelling.
Avoid using the command abbreviations.
If you use the " command to have command headers included as part of
query responses, you can further control whether the returned headers are
abbreviated or are full-length. The # command lets you control this.
You can concatenate any combination of set commands and queries using a
semicolon (;). The digitizing oscilloscope executes concatenated commands in
the order received.
When concatenating commands and queries, you must follow these rules:
1. Separate completely different headers by a semicolon and by the beginning
colon on all commands but the first. For example, the commands &
" and $" would be concatenated into a
single command:
" $"
2. If concatenated commands have headers that differ by only the last mnemon-
ic, you can abbreviate the second command and eliminate the beginning
colon. For example, you can concatenate the commands $"
and $" into a single command:
$"
The longer version works equally well:
$" $"
3. Never precede a star (*) command with a colon:
$"
