Remote Operation
Model 1120 Remote Control Operation
Commands are sent to the Model 1120 as if the user were entering them at the front panel. For
example, the string of 4.581MUZ would return 4.581 mV in copper mode. If an error is made in
the command, the Model 1120 returns an Error Code. In the Model 1140A using Model 1120
Remote Emulation, when an incorrect command is sent the applicable Error Code is returned to
the front panel between the annunciator 1120 MODE and the large value in the middle.
Table 6-3 gives all the valid commands (keystrokes) of the Model 1120 that are emulated in the
Model 1140A. Although the STO (store) and RCL (recall) commands will not return an error,
they are not supported by the Model 1140A.
