User and Remote Interface Security Measures

Administrative Password

To reset an instrument's administrative password, follow the procedure in the AC6800A Operating
and Service Guide. This involves removing power and other connections to the instrument,
removing the instrument cover (requires tools), changing a switch position, and cycling power.
The password never expires.
This instrument does not track or report invalid password attempts, nor does it lock-out password
entry following a number of invalid password entries.

Remote Access Interfaces

The user is responsible for providing security for the I/O ports for remote access by controlling
physical access to the I/O ports. The I/O ports must be controlled because they provide access to
all user settings, user states and the display image. The I/O ports include USB, GPIB, and LAN.
1. The LAN port provides the following services, which can be selectively disabled:
a. VXI-11
b. Sockets
c. Telnet
d. Web instrument control
e. mDNS
f. HiSLIP
To disable LAN services:
On the front panel press [Menu] > System > LAN > Modify > Services.
To disable USB or GPIB:
On the front panel press [Menu] > System > Admin > IO.

Controlling the front panel display

The front panel display can be turned off from the remote interface by sending the command:
DISPlay OFF
The display is enabled when power is cycled.

Calibration regulation

The instrument requires a password to allow calibration. The instrument's calibration count will
increment each time calibration data is saved.
