4.1 GPIB Remote Programming
4.1.11 Data Output Format (talker)
In order to output internal data such as measured data and set conditions, it is necessary to specify the data
using the "xx?" command. This data is then output when the device is in the talker mode. Available output
formats are as listed in the table below. The delimiter positioned at the end of data can be specified from
5 types (refer to "Others" in the GPIB code list). Once set, "xx?" command continues to be valid until it
is changed.
<Supplement>
1= Sign (a space for plus sign; "-" for minus sign)
2= Mantissa of data
3= Exponent of data
4 = Delimiter (CR/LF in initial setting can be changed with "DLn" code.)
