number, then no further action is necessary. Otherwise, press
the fourth key. Rotate the knob until line 4 indicates the
desired address. In this example, 15 is the desired address:
-----SETTINGS-----
Type: GPIB
Option: Address
<Update?: 15
Then press the fourth key to confirm the update. Pressing
any other button cancels the change.
Menu preferences are not normally retained after the power is
removed from the instrument. To make (a) menu preference(s)
permanent, make the desired change(s) to settings first and
then proceed to the section Storing the Menu Preferences to
make the changes permanent. Following this procedure will
put the settings into non-volatile memory and allow them to
be restored during instrument power-up.
The 1256 may generate a service request (SRQ) in response to a
variety of events. These events include detecting a programming
error or confidence mode failure, generating a response to a query,
and many others.
Consult the IEEE-488.2 Status Description section in Chapter 5,
SCPI Command BASICS for a description of how to program the
1256 to generate a service request.
The RS-232 interface provides a simple way to control the 1256
from virtually any computer. Nearly every computer has a serial
(Com) port. The only extra hardware required is a serial cable.
This section gives information about connecting the 1256 to the
computer via serial cable, setting up the 1256 for serial port
operation, and communicating with the 1256 by using a terminal
emulation program.
