Functional Syntax Elements (continued)
General rules:
1. <program mnemonic> shall have maximum length of 12 characters.
2. “:” is used to separate <program mnemonics>, and when preceding a
<PROGRAM MESSAGE UNIT>, it indicates that the following <program mnemonic> is
at the root level.
<PROGRAM MESSAGE UNIT>
1. <program mnemonic> can be either upper or lower case alpha.
2. <white space> is only allowed at the end of the header, or next to a “,” or a “;”.
(See note on <white space> below.)
<RESPONSE MESSAGE UNIT>
1. <program mnemonic> shall contain upper case alpha only.
2. No <white space> allowed in message header. To receive a response to a query command,
append “^D” (ASCII 4 or CTRL-D) to the <RESPONSE MESSAGE UNIT>. For example, after
sending *IDN?<RMT> followed by “^D”, the 2411B will respond with “TEGAM, Model
2411B, 0, <firmware_rev_levl>”.
Note: <white space> is defined as a length of 1 or more of <white space characters>. A <white space
character> is a single ASCII byte in the range of 00-09, OB-20 Hex.
<PROGRAM MESSAGE> - This is a series of<PROGRAM MESSAGE
UNITS> sent to the device in a single string. For example, to set the currently selected waveform to
1) a sinewave output with phase zero, 2) burst mode, 3)a burst of 5, and 4) an amplitude of 2.5Vp-p into
50
Ω
, you would send the following <PROGRAM MESSAGE>:
WVFM:SINE 0;:MODE BURST;:BURST 5;:AMPL 2.5
{ msg 1 } { msg 2 } { msg 3 } { msg 4 }
The semicolon (ASCII 3B) is required to separate <PROGRAM MESSAGE UNITS> within a
<PROGRAM MESSAGE>. For the 2411B a <PROGRAM MESSAGE> can be virtually any length.
The structure for a <RESPONSE MESSAGE> for query responses is similar.
