Connect the instruments

z Before connecting the system bus, you must ensure that each instrument is

in single mode (Single).

z Fiber optic cables cannot be flexed or folded. When the cable is too long

and needs to be arranged, gently wrap the cable in a circle and gently tie it.

z Before connecting the cables, ensure that the instrument power switch is off

and the main switch of the AC power input (distribution box) is off.

z Before connecting 3 single instruments to the AC distribution box, ensure

that the distribution box capacity is sufficient. Refer to the corresponding

specifications for the AC input parameters of a single instrument.

For 3U models, the same model can be connected in parallel. Taking three 3U

single instruments (with operation panel) as an example, the steps for parallel

operation are as follows.

1. Ensure that the power switches of the three units and the main switch of the

AC power distribution box are off.

2. Refer wiring connection diagram to connect three units.

3. Connect the AC input terminals of the three units separately, and connect

them to the AC distribution box.

4. Connect the output terminals of the three units in parallel and connect them

to the DUT.
