Command Syntax
2–8
TDS Family Oscilloscope Programmer Manual
This is also the preferred format when sending the command to the digitizing
oscilloscope though any of the formats will be accepted. This manual represents
these arguments as follows:
Symbol Meaning
<NR1> Signed integer value
<NR2> Floating point value without an exponent
<NR3> Floating point value with an exponent
Most numeric arguments will be automatically forced to a valid setting, either by
rounding or truncating, when an invalid number is input unless otherwise noted
in the command description.
Some commands accept or return data in the form of a quoted string, which is
simply a group of ASCII characters enclosed by a single quote (') or double
quote ("). For example:
"this is a quoted string"
Symbol Meaning
<QString> Quoted string of ASCII text
Follow these rules when you use quoted strings:
1. A quoted string can include any character defined in the 7-bit ASCII
character set. (See Appendix A: Character Charts on page A–2).
2. Use the same type of quote character to open and close the string:
"this is a valid string"
3. You can mix quotation marks within a string as long as you follow the
previous rule:
"this is an 'acceptable' string"
4. You can include a quote character within a string simply by repeating the
quote. For example,
"here is a "" mark"
5. Strings can have upper or lower case characters.
6. If you use a GPIB network, you cannot terminate a quoted string with the
END message before the closing delimiter.
