TABLE 3-3 SCPI COMMANDS AND QUERIES
(Continued)
:DATA
-
Digital data identifier
[:VALue]?
-
Reads input ports selected by Configure
branch. Format set by FORMat:TALK
setting.
:PORT?
-
Sets bytes to inputs if not already inputs
and returns value of signals on the bytes
specified in the attached channel list.
Format set by FORMat:TALK setting.
i.e. SENS:DATA:PORT? (@ 1:4)
:PORTn?
-
Five queries that set the byte as an input if
not already an input and returns the value
of the signals on the associated byte. For-
mat set by FORMat:TALK setting. Value
of n is 1 to 4 i.e. SENS:DATA:PORT3?
:POLarity
255
Sets input byte polarity. Value is 0 to 255
in decimal. See note 12.
MEASure
Starts Measure branch
:VOLTage?
Lists A/D input channels to be measured.
Value can be a simple number (1-6) or a
SCPI list e.g. (@ 1:6) Channel numbers
are 0 for temperature subsystem, 1-6
for voltage inputs, 7 for D/A reference
voltage (2.5v). e.g. MEAS:VOLT? 2.
:RANGe
10
Selects A/D input range in volts for each
channel. Command format is Channel
number, value. Channel number=1 to 6.
Values are 5 and 10
:POLarity
2
Selects input polarity. Command format
is Channel number, value. Channel num-
ber=1 to 6. Values are 1 for unipolar 0 to
+V ranges and 2 for bipolar -V to + V
input ranges.
:AVERage
25
Sets averaging value for each input chan-
nel. Momentarily setting the AVERage
