6 • Introduction
1. Use one of the supplied power cables to connect
the photoreceiver to a ±15-volt power source that
can supply 200 mA. (Page 11.)
For the Newport Model 0901 power supply, use
the 0923 power cable. For other power supplies,
use the 0924 banana plug power cable.
When using the 0924 cable, take care to hook up
the banana plugs as follows to avoid damaging the
photoreceiver: Red = +15 V, Black = -15 V, Green =
Ground.
2. Mount the photoreceiver to your optical table. A
pair of 8-32 and a pair of M4-threaded holes are
located on the bottom of the unit. (Page 12.)
3. Connect the optical source to one or both optical
inputs. (Page 12.)
For the free space model, take care not to overfill
the photodiode. The 1607-AC has a 0.4-mm
diameter photodiode; the 1617-AC has a 0.1-mm
diameter photodiode.
To prevent saturation of the RF amplifier, keep the
input power below the saturation power shown on
page 16.
The optical power must remain below the absolute
maximum power listed in the specifications on page 16.
Exceeding the maximum power can damage the
photodiode and the amplifier.
4. Use the low-frequency I1and I2outputs to check
and adjust the optical inputs so that the output
powers are in the desired 0–10 V range. (Page 13.)
You can use the I2 - I1output to fine tune the
optical power balance between the two diodes.
5. Finally, connect the RF Out SMA connector to the
desired load or instrument via a 50-Wcoaxial
cable. (Page 13.)
