Connecting to the 5700A Calibrator

2-6.

Proceed as follows to connect the 5725A to the 5700A:

1.Turn the power off for both instruments and disconnect their line power cords.

2.Connect either end of the interface cable to the 5725A connector labeled 5700A. Dress the cable only as Figure 2-2 shows. The figure shows how to dress the cable in installation arrangements with the 5725A on top or bottom.

3.Connect the other end to the 5700A connector labeled 5725A.

The 5700A/5725A interface cable provides all the digital and analog control signals for the amplifier, and it provides conductors to route amplified voltage to the 5700A OUTPUT binding posts.
