For example, to jump directly to ac volts calibration, send the command:
To go directly to Resistance calibration, send the command:
These calibration commands can be used with either the IEEE-488 or serial interface. To
use the serial interface, and without having to write a calibration program, do the
following:
1. Connect the appropriate COM port from a PC to the 5520A Serial 1 connector, using
2. Call up the Terminal program from within Microsoft Windows. Set the
3. Press
The following is an alphabetical list of the IEEE-488/RS-232 remote calibration
commands for the 5520A Calibrator (for remote commands pertaining to normal
operation of the 5520A, please see the 5520A Operators Manual ). For sorting purposes,
this list ignores the * character that precedes the common commands. The remote
commands duplicate activities that can be initiated from the front panel in local operation.
IEEE-488 (GPIB) and RS-232 Applicability Each command title listed in this section
shares the same remote interface applicability, IEEE-488 (general purpose interface bus,
or GPIB) and RS-232 remote operations, and command group: Sequential, Overlapped,
and Coupled.
x IEEE-488
Sequential Commands Commands executed immediately as they are encountered in the
data stream are called sequential commands. Anything not overlapped or coupled is
sequential.
Overlapped Commands Commands that require additional time to execute are called
overlapped commands because they can overlap the next command before completing
execution.
Coupled Commands Some commands are coupled commands because they "couple" in
a compound command sequence. Care must be taken to be sure the action of one
command does not disable the action of a second command and thereby cause a fault.
