Overview
Contacting OptoTest
The OP740 High Speed Multichannel OPM offers a
state-of-the art solution for high speed optical power
measurement applications where multiple channels
are needed. Unlike many other systems, this
instrument is comprised of individual power meters
allowing for simultaneous data acquisition over all
channels with unparalleled speed.
The O P740 is available with 4 to 24 channels and can
be configured for a variety of detector and connector
interfaces. With the rack mount option, multiple units
can be combined for even higher channel counts.
This quick start guide will demonstrate the steps
necessary to begin monitoring optical power using
the O P74 0.

To begin, the 9V power supply and power cord should
be connected to each other, a wall outlet, and the
OP740 . Either the USB A-B cable or the USB-C
cable should be used to connect the OP740 to

the operating PC for communication and control
through software.
Note: The USB-C is required for high-speed
acquisition, while the USB-B port allows the OP740 to
be used as an OP710 in OPL-Suite Software such as
OPL-MAX and OPL-LOG.
To power on, turn the key clockwise 90 degrees from
horizontal to vertical position.
