2-32 3700S-901-01 Rev. C / July 2008
Differences: Remote versus local state
The Series 3700 can be in either the local state or the remote state.
When it is in the local state (REM annunciator off), the instrument is
operated using the front panel controls.
When it is in the remote state (REM annunciator on), instrument operation is
controlled by the computer.
When the instrument is powered-on, it is in the local state.
Remote state
The following actions will place the instrument in the remote state:
Sending a command from the computer to the instrument
Running a script (a USER test) from the front panel; after the test is
completed, the instrument will return to the local mode
Opening communications between the instrument and Test Script Builder
Web-control (logging in to the Series 3700 web interface)
While the instrument is in the remote state, front panel controls are disabled.
However, the LOCAL key will be active unless it has not been explicitly locked
out by the user program. When an interactive script is running, use the activated
front panel controls to input parameter values.
Local state
The following actions will cancel the remote state and return the instrument to
the local state:
Cycling power for the instrument
Pressing front panel LOCAL key (if it is not locked out)
Sending the abort command from the PC
Clicking the Abort Execution icon on the toolbar of the Instrument Console
for Test Script Builder
After a front panel script (a USER test) is completed, the instrument will return to
the local state.
TSP-LinkTM system
A test system can be expanded to include up to 64 instruments that are enabled
using TSP-Link. The system can be stand-alone or PC-based.
