Learn Mode #2
Learn Mode #2 is used to return the 8650B configuration information to the controller in the form of a series of
binary values. Learn Mode #2 is valid only over the GPIB interface.
3.14.3.1
Requesting the String
The simple command which requests the Learn Mode #2 string has the following format:
Syntax:
LP2
Example:
LP2
! REQUESTS LEARN MODE #2 STRING
Response:
@2(string of 28 8-bit binary bytes)<CR><LF>
After receiving the LP2 command, the 8650B will return the Learn Mode #2 string the next time it is addressed
to talk. The string starts with two ASCII characters, @ and 2, followed by a string of 28 (58 for the 437 emulation
mode) 8-bit binary bytes. The last byte is sent with EOI true. Learn Mode #2 requires a controller that can
receive and send information in binary form.
The Learn Mode #2 string contains the following information:
•
Measurement mode
•
REL mode status (ON | OFF)
•
Reference oscillator status (ON | OFF)
•
Current reference value if in REL mode
•
Measurement units (Log or Lin)
•
Cal Factor for each sensor
•
Offset for each sensor
•
Range for each sensor
•
Filter for each sensor
3.14.3.2
Sending the String
The command that sends the Learn Mode #2 data to the 8650B is based on the GPIB @2 function. The command
format is:
binary bytes
The 8650B will change its configuration to match the configuration defined by the Learn Mode #2 string.
