coupling ratio, and its wavelength dependence, for the Monitor Output yourself.

A.7 Optical Output

The attenuator is supplied with either a straight contact connector or an angled contact connector (Option 201). Make sure that you only use the correct cables with your chosen output. See “Connector Interfaces and Other Accessories” on page 158 for further details on connector interfaces and accessories.

Disabling the Optical Output

If the optical output is enabled (that is, the green LED is lit), you can disable it by pressing ENB/DIS.

Depending on the attenuation setting, it can take up to 3 seconds for the output to be disabled (typically delay, 1 second).

A.8 GPIB Interface

You can connect your GPIB interface into a star network, a linear network, or a combination star and linear network. The limitations imposed on this network are as follows:

The total cable length cannot exceed 20 meters

The maximum cable length per device is 2 meters

No more than 15 devices may be interconnected on one bus.
