F2R3Z1N4 [ALPHA
ALPHA] OUTA
Comments
OUTA (OUTput Alpha register) causes the contents of the Alpha register to be
output to the selected device. In the example shown above, the Alpha register is
loaded with the command string: F2R3Z1N4.
When OUTA is executed (3468A is selected), the multimeter will be set to the ac
volts function (F2), 30 volt range (R3), autozero on (Z1), and 4 1/2 digit display
mode (N4).
Normally, the OUTA command is terminated with a Carriage Return (CR), Line
Feed (LF). The 3468A, however, ignores these characters.

Comments
The IND (INput Decimal} command retrieves an ASClIl-coded numeric value from
the “SELECTED” device and places it into the X-register of the calculator. When
this command is executed and the 3468A is the selected device, the 3468A
becomes a talker and outputs one measurement value of 13 bytes in the form:
+/-d.dddddE+/-d CR LF
where “d” represents a single digit, CR is Carriage Return, and LF is Line Feed. If
the 3468A is in the 4 1/2 digit display mode, the last digit returned before the E
will be a 0. In the 3 1/2 digit mode, the last two digits will be O’s. CR LF is a
standard end-of-line indicator and does not show in the display.
Overload conditions are sent through the loop as:
+9.99999E+9 CR LF
