When reading: an number corresponding to a channel number and data value as
shown above.
RN/WN Read/Write DAC Zero-Scale Value
Purpose Reads or writes the channel’s “DAC.ZERO-SCALE” menu item.
Usage
“#aaccRN
↵
” to read, “#aaccWNn
↵
” to write
# is the ‘pound’ or ‘hash’ character (ASCII decimal 35).
aa is the two-character instrument address.
cc is the two-character channel number.
n is the zero Analog Output value in engineering units.
↵
is the ’carriage return’ character (ASCII decimal 13).
Example
“#0004WN-8000
↵
” sets the zero-scale value of channel 04’s DAC to –8000.
Reply When writing: “OK” or “ERROR”
When reading: an ASCII-floating-point value.
RO/WO Read/Write DAC Full-Scale Value
Purpose Reads or writes the channel’s “DAC.FULL-SCALE” menu items.
Usage
“#aaccRO
↵
” to read, “#aaccWOn
↵
” to write.
# is the ‘pound’ or ‘hash’ character (ASCII decimal 35).
aa is the two-character instrument address.
cc is the two-character channel number.
n is the zero Analog Output value in engineering units.
↵
is the ’carriage return’ character (ASCII decimal 13).
Example
“#0001WO8000
↵
”
Reply When writing: “OK” or “ERROR”
When reading: an ASCII-floating point value.
Chapter 13 Split-Display Virtual Channel Commands
13.1 Introduction
These commands affect the operation of Split-Display Virtual channels
13.2 Descriptions
FO Transmit Track Data
Purpose To maintain compatibility with other types of channels.
Usage
“#aaccFO
↵
"
# is the 'pound' or 'hash' character (ASCII decimal 35).
aa is the two-character instrument address.
cc is the two-character channel number
↵
is the 'carriage return' character (ASCII decimal 13).
Example
“#0002FO
↵
"
Reply “ 00000."
Remarks Since this channel generates no track, peak or valley data values, this command always
returns 0.
F9 Transmit Peak Data
Purpose To maintain compatibility with other types of channels
Usage
“#aaccF9
↵
"
# is the 'pound' or 'hash' character (ASCII decimal 35).
aa is the two-character instrument address.
cc is the two-character channel number
↵
is the 'carriage return' character (ASCII decimal 13).
