Model 2520 User’s Manual SCPI Command Reference 14-25
CURRent2 — This element provides the detector #1 current reading. If
no current reading is available, the NAN (not a number) value of
+9.91e37 is used.
CURRent3 — This element provides the detector #2 current reading. If
no current reading is available, the NAN (not a number) value of
+9.91e37 is used.
TIME — This element returns the timestamp value. The first reading
taken during the pulse will be given a TIME value of 0. The TIME value
is then incremented by 100ns for each successive reading.
NOTE
In the pulse mode, the current source pulse will not necessarily start at the first
reading and may be delayed by up to five readings (500ns). To determine when
the pulse actually occurs, you must look at the measurement data.
SOURce4 <name>
:FORMat:SOURce4 <name> Set SOUR4:TTL response format
Parameters
<name> = ASCii ASCII format
HEXadecimal Hexadecimal format
OCTal Octal format
BINary Binary format
Query
:SOURce4? Query response format
Description
This command controls the response format for the SOUR4:TTL query
in a manner similar to formats set by the FORM:SREG command. See
“SOURce subsystem,” page 14-32 , for details.
Byte order
BORDer <name>
:FORMat:BORDer <name> Specify binary byte order
Parameters
<name> = NORMal Normal byte order for binary formats
SWAPped Reverse byte order for binary formats
Query
:BORDer? Query byte order
Description
This command is used to control the byte order for the IEEE-754 binary
formats. For normal byte order, the data format for each element is sent
as follows:
Byte 1 Byte 2 Byte 3 Byte 4 (Single precision)
For reverse byte order, the data format for each element is sent as fol-
lows:
Byte 4 Byte 3 Byte 2 Byte 1 (Single precision)
