Other functions Relative value display Carrier frequency and output level

Offset display Carrier frequency and output level

Memory 1000 panel setting conditions can be stored and recalled.

Recall mode: All panel settings, Frequency only, Frequency and Level.

Trigger function An external trigger signal (input from the BNC connector on the rear

panel, TTL level) can be used to execute a pre-programmed operation

sequence (except for operation of the power switch, Preset key, Local

key, and rotary knob).

Max. number of sequence steps of trigger program: 20 steps

Backup When switched on, the generator restores the same setting conditions

that existed immediately before it was last powered off.

However, the following are not restored:

• Data which was in the middle of entry

• Remote status

• Data which was in the middle of GPIB transfer

• Operating status of RPP

GPIB Can control all functions, except for pre-programmed operations

controlled by the trigger function, and operation of the power switch,

Local key, rotary knob, and knob resolution set keys.

Interface: SH1, AH1, T5, L3, TE0, SR1, RL1, PP0, DC1, DT1, C0,

E2
