localnode.PASSWORD_WEB. Passwords are only required for the web interface.
localnode.PASSWORD_LAN. Enables passwords on all Ethernet and web interfaces.
localnode.PASSWORD_ALL. Protects the LAN and all command and web interfaces.
localnode.PASSWORD_NONE. Disables all passwords.
The password lock feature on Model 2657A is similar to the lock feature on your computer.
You must enable passwords to use this feature.
To lock the instrument when you are away from the testing area, send the following command:
password
The remote interface is locked. The Model 2657A does not respond to commands issued from the
command interface until you unlock the interface. This reserves the instrument and protects the test
script running on the instrument.
