Buffer Data Bn
The Buffer Data command, Bn, allows the user to write data to the data buffer.
The data buffer consists of 4096 locations. Each location can store one character (a
binary number from 0 to 255). Data sent to the buffer is stored as it is received. When
the Analyzer488 is commanded to output data from the data buffer, all data currently in
the buffer is output in the order that it was received. The Execute command (X) is not
required when using the Buffer Data command.
The data sent with this command may be a delimited string or a number in the
range 0 to 255. Once the buffer is full, any excess data sent to the buffer will be
ignored. The entire buffer may be cleared by executing the Clear Buffer (C0)
command.
A string is a list of alphanumeric characters delimited at the beginning and end
by single character. The delimiter can be a Slash (/), Backslash (\), Single Quote ('),
or Double Quote ("). The delimiter is taken as the first of these characters after the B
and the Analyzer488 will accept all input up to the next occurrence of that character as
the string to be displayed. It is up to the user to insure that the opening and closing
delimiters match.
SYNTAX: B/string/ Send a string to the data buffer. A string may be
one or more characters.
Bn,m,z
Send a binary value to the data buffer (n,m,z can
be 0 to 255)
B?
Always returns B0
Note: Any number of data values may be sent when specifying data
as binary values.
EXAMPLES: PRINT#1,"CLEAR10" reset the Analyzer488
PRINT#1,"OUTPUT10;C0X" clear the Analyzer488 data buffer
PRINT#1,"OUTPUT10;B/NDCV+0.0000E+0/" send the
string NDCV+0.0000E+0 to the data
buffer
PRINT#1,"OUTPUT10;B13,10" send ASCII codes for a
Carriage Return and Line Feed
PRINT#1,"OUTPUT10;W21X" select Waveform 21 (the user
waveform)
