Receiving Information
from the instrument
introduction to Programming an Instrument
1-12
This program demonstrates the basic command structure used to program
the HP 1650B/51B.
10 CLEAR XXX
20 OUTPUT XXX;":SYSTEM:HEADER
30 OUTPUT XXX;" :SYSTEM:LDNGFORM
40 OUTPUT XXX;" :MMEM:LOAD:CONFIG
50 OUTPUT FDRMAT.l"
60 OUTPUT
70 OUTPUT XXX;":START"
Line 10 initializes the instrument interface to a known state
Line 40 loads the configuration file "TEST-E" from the disc drive.
Line 50 displays the Format menu for machme 1.
Lines 60 and 70 tell the analyzer to run the measurement configured by
the file "TEST-E" one time.
After receiving a query (command header followed by a question mark),
the instrument interrogates the requested function and places the answer
in its output queue. The answer remains in the output queue until it is
read or another command is issued. When read, the message is
transmitted across the bus to the designated listener (typically a
controller). The input statement for receiving a response message from
an instrument's output queue typically has two parameters; the device
address and a format specification for handling the response message.
For example, to read the result of the query command
:SYSTEM:LONGFORM? you could execute the BASIC statement:
ENTER HOQ Setting
where XXX represents the address of your device. This would enter the
current setting for the longform command in the numeric variable Setting.
