Operation and Programming
3-177.
SYSTEM CONTROLLER MODE (AUTO LOCK)
3-178.
In the Auto Lock mode, there is no calculator or computer controlling the HP-IB. Instead, the
5344A is placed in the System Controller mode by setting the rear panel ADDRESS switch to the SYS
CONT position. The 5344A HP-IB connector is connected directly to the HP-IB connector of the
8350A or 8620C Option Oil Sweep Oscillator. No other powered-up controllers may be connected to
the bus.
3-179.
The 5344A now has the ability to program the sweep parameters based on data entered on
the 5344A keyboard. For instance, 2 GHz is entered into the 5344A keyboard in the CW Mode. When
the AUTO LOCK key is pressed, the 5344A wiil program the sweeper to 2 GHz. Provided the sweeper
is properly aligned, the actual output frequency should be within the 5344S lock range. If the actual
frequency is not within the lock range, the 5344A will alter the bus code in an attempt to bring the
sweeper within lock range. If the 5344A is unsuccessful, Err 11 will be displayed on the 5344A.
3-180.
The address of the 5344A and the sweeper must be set to the same value.
3-181.
The 5344S cannot be operated in Auto Lock/Roll with an 8620 series sweeper.

The 5344S acts as a system controller for an HP 8620C or HP 8350A sweeper. No other system
controller may be on the bus. The 5344S HP-IB address switch must be set to the address of the
sweeper, and the system controller switch must be in the SYS CONT. position.
