following sections describe how to set the OM instrument IP addresses for use
on DHCP and non-DHCP networks.
The OM instrument is set with automatic IP assignment (DHCP) enabled by
default. Therefore you do not need to specifically set the instrument IP address, as
the DHCP server automatically assigns an IP address during instrument power-on.
The following procedure describes how to use LRCP software to verify
connectivity of the OM instrument to a DHCP-enabled network.
Prerequisite: OM instrument, and a controller PC (with LRCP installed), both
connected to the same DHCP-enabled network.
1. Connect the OM instrument to the DHCP-enabled network.
2. Power on the OM instrument with the rear power switch (set to 1). The
instrument queries the DHCP server to obtain an IP address. Wait until the

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
address of 172.17.200.XXX, where XXX is any number between 0 and 255. Use
the operating systems of the oscilloscope and computer to set their IP addresses.
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 series instrument:

Use LRCP on a PC set to the same IP address as the OM instrument to change
the OM instrument IP address
Use DHCP network to change IP address. To use a DHCP network to change
the IP address of an OM instrument:
1. Do steps 1 through 6 of the Set network access (DHCP network) procedure.
2. Click the Set IP button in the instrument list.
3. Use the dialog box to enter the new IP address and related parameters for the
OM instrument.
4. Click OK to close the dialog box and set the IP address.
5. Exit the LRCP program.
6. Power off the OM instrument and connect it to the non-DHCP network.
7. Run LRCP and use the Auto Config button in the Device Setup dialog box to
verify that the instrument is listed.
Use direct PC connection to change IP address. To use a direct PC connection to
change the default IP address of an OM series instrument, you need to:
onnected to a DHCP-enabled network (easiest)
Install LRPC on the PC
Use the Windows Network tools to get the IP address of the PC to match that
of the current subnet setting of the OM series instrument whose IP address
you need to change

The Laser Rece
iver Control Panel (LRCP) user interface
The Laser-Receiver Control Panel application (LRCP) is used to control a variety
of Integratable Tunable Laser Assembly (ITLA) lasers. The LRCP interface
simplifies th
commands. The interface automates locating and configuring all OM devices that
are present on the local network. It also provides a Windows Communication
Foundation (WCF) service interface, allowing Automated Test Equipment (ATE)
to interact directly with the controllers and lasers while LRCP is running.

The main components of the LRCP user interface are:

from an instrument. This readout is only functional on devices like the
OM4000 instruments that have the appropriate hardware installed.
Click the Device Setup button to open the Device Setup dialog box. Use this
dialog box on initial setup of the controllers and anytime network configuration
changes and devices are moved to a new IP address. Click the Auto Configure
button to have LRCP search for and list detected OM devices.

the Friendly Name. Setting this value for each device will aid in the identification
of the physical location of the controllers as Friendly Names are retained and are
tied to the corresponding MAC Address. Make sure to exit the form by clicking
the OK button to save changes.
The Set button is used to modify the addressing as described in the next section. It
is not necessary to use the Set button to change the Friendly Name.
Each device must be assigned an IP address in order to communicate with the
device. How you manage IP addresses in your network, namely with or without
DHCP, will determine the method in which you connect to the devices on your
network.
Once configured and detected, devices are listed as tabs on the main LRCP
screen. They are listed with the friendly name and IP address to allow for easy
identifi
and once the controller is brought online the laser panels will populate with the
laser manufacturer and model number.
Once the user presses the button that reads Offline the button will change colors
as the control panel attaches to the OM instrument. First, the button will turn
yellow and read “Connecting…” indicating that a physical network connection
is being established over a socket. Second, the button will turn teal and read
“Connected…”. This indicates that a session is established between the device

NOTE. The button color scheme of bright green meaning running or active,
grey meaning off line or inactive and red indicating a warning or error state is
consistent throughout the application.
Once the controller tab is active and the laser panels have populated with the
corresponding laser information the user is free to put change the laser settings
and/or turn the lasers on. When the controller is first turned on the current state of
the hardware is read to pre-populate the laser panel. Any time you exit application,
the current state of the lasers is preserved, including the emission state.
If the lasers are used in conjunction with the OM instrument and OUI, the laser
usage type needs to be set using the dialog on the lower right corner of each
laser panel. The OUI uses the setting to determine from which laser frequency
information is retrieved. A usage type can only be selected once between all of
the controllers but you can have one usage type on one controller and another
usage type on a second controller.

The receiver gauge (shown at the bottom of the LRCP window) is only active
for equipment that have the appropriate hardware present (such as the OM
instruments). The receiver gauge, when active, displays the total photocurrent.
NOTE. For all text field entries it is necessary to click away from the field, or press
the Tab key, for the value entered to be accepted by the application.
CAUTION. The LRCP saves all laser parameter settings, including the emission
output value, when you exit the application, including the emission state. Make
sure to verify laser emission parameters before running tests on a new test setup.

Cavity Lock: The Intel/Emcore ITLA laser that is included in the
OM4000 instruments has the ability to toggle its channel lock function.
Ordinarily, Cavity Lock should be checked so that the laser is able to tune and

laser has stabilized, this box can be unc hecked to turn off the frequency dither

Fine Tune: The Intel/Emcore lasers can be tuned off grid up to 12 GHz. This
can be done by typing a number in the text box or by dragging the slider. The
sum of the text box and slider values will be sent to the laser. Once the laser
has accepted the new value it will be displayed after the ‘=’ sign.

Using this grid plus Fine Tune, any frequency in the laser band is accessible.
Laser Electrical Power: This should normally be checked. Clearing this box
turns off electrical power to the laser module. This should only be needed to
reset the laser to its power-on state, or to save electrical power if a particular
laser is never used.
Channel setting within the ITLA grid gives the corresponding frequency (in THz)
and wavelength (in nm). Power is set within the range allowed by the laser. It is

The first specifies the URL or path to a WSDL application programming interface
(API) that defines the web service methods, arguments, transactions.
The second creates the new class based upon that API and builds a series of
