Removing Quad-adapter Interfaces from the Keysight
N7744/5A Multiport Power Meter
There are release levers on both sides of the quad-adapter for removing it from the
optical inputs.
Figure 10 Removing Quad-adapter Interfaces
1 Press the release levers on both sides of the quad-adapter to release
it from the front panel of the power meter.
2 You can now remove the optical connectors from the quad-adapter.
Always place the dust cap on unused connector interfaces.
You can use the quad-adapter dust caps to protect the four power meter inputs and
the rear of the quad-adapter, for example, when fibers are attached.
There are two BNC connectors on the rear panel of your instrument.
These are the Trigger Out and the Trigger In connectors.
The N7747A and N7748A have a front panel BNC connector for each
channel. These are for analog output signals and provide a voltage
proportional to the input signal power in mW. The voltage is in the range
0-2 V and 1 V corresponds to the value of the currently selected power
range. For example, when using the -10 dBm range, a 100 µW optical
power will give 1 V analog output.
