Install software
The OM1106 Optical Modulation Analyzer software (referred to as OMA in this
document) provides an ideal platform for research and testing of coherent optical
systems. It o
ffers a complete software package for acquiring, demodulating,
analyzing, and visualizing complex modulated systems with an easy-to-useuser
interface. The software performs all calibration and processing functions to enable
real-time burst-mode constellation diagram display, eye diagram display, Poincaré
sphere display, and BER evaluation.
This section describes how to install and configure the OMA software and OM
series instruments to correctly communicate with each other.
PC hardwa
re and software requirements
The following are the PC requirements needed to install and run the OMA
software to control the OM4000 and OM2000 series instruments. The term PC
s to a supported oscilloscope, PC, or laptop on which the OMA and other
applie
required software is installed, and that is connected to OM instruments over
a local network.

To install the power meter software:
1. Insert the product software media USB drive into a USB port on the controller
PC (where the OMA software will be installed).
2. Navigate to the following file (from the USB root drive):
ThorLabsSoftware\PM100x_Instrument_Driver_64bit_V3.1.0.zip
3. Double-click the file to display the compressed file contents.
NOTE. Windows 7 comes with a .zip-file-compatible compression-decompression
program. If you cannot access the contents of the .zip file, check that the .zip file
type is associated with the decompression program.

that IP addresses of the connected OM series instruments are set correctly for
your network, to enable communications between the instruments and the OMA
software. The following sections describe how to connect OM instruments to
DHCP and non-DHCP networks.
All OM instruments must be set to the same network subnet (DHCP-enabled
networks do this automatically) to communicate with each other.
OM series instruments are set by default to use DHCP to automatically assignIP
addresses. If you are connecting the OM instruments and PC controller over a
DHCP net
as the DHCP server automatically assigns an IP address during each instrument’s
power-on process.
The following procedure describes how to verify that the OMA software can
detect and connect to OM instruments that are set to use DHCP-generated IP
addresses on a DHCP-enabled network:
n use the OMA software to take measurements, you must make sure

Prerequisites:
Required software is installed on the controller PC (OMA, MATLAB, and so
on).
OM instrument(s) and the controller PC are connected to the same
DHCP-enabled local network.
OM instruments are set to use DHCP (default configuration).

To connect the OM series instrument to a non-DHCP network, you must set the
IP address and related settings on the OM instrument to match those of your
non-DHCP net
PCs running OM software, and other remotely accessed instruments such as
oscilloscopes) need the same subnet values (first three number groups of theIP
address) to communicate, and a unique instrument identifier (the fourth number
group of the IP address) to identify each instrument.
Work with your network administrator to obtain a unique IP address for each
device. If your network administrator needs the MAC address of the OM
instrument, the MAC address is located on the instrument rear panel label.
NOTE. Ma

If you are setting up a new isolated network just for controlling OM and associated
instruments, Tektronix recommends using the OM instrument default IP subnet

NOTE. If you need to change the default IP address of more than one OM
instrument, you must connect each instrument separately to change the IP address.
There are two ways to change the IP address of an OM instrument:
Connect the OM instrument(s) to a DHCP-enabled network and use the LRCP
tab in OMA to change the IP address (easiest way).
Connect the OM instrument directly to a PC (with OMA installed) that is
already set to the same IP address subnet as the OM instrument, and use the
LRCP tab controls in OMA to change the IP address.
To use a DHCP network to change the IP address of an OM instrument:
1. Connect the OM instrument(s) to the DHCP-enabled network.
2. Power on the OM instrument. The instrument queries the DHCP server
to obtain an IP address. Wait until the front panel Enable/Standby button
light turns off, indicating it has obtained an address. Push the front panel
