Figure 1: IP address setup (LRCP)

Before using LRCP, you must make sure that IP addresses of the OM series instruments are set correctly to communicate with LRCP on your network. The following sections describe how to set the OM instrument IP addresses for use on DHCP and non-DHCP networks.

The OM instruments are 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 when the rear-panel power switch is turned on.

The following procedure describes how to use LRCP software to verify connectivity of an OM instrument to a DHCP-enabled network.

Prerequisite: OM instrument, and the 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

Work with your network a dministrator to obtain a unique IP address for each device. Your network administrator may need the MAC addresses of the computer, oscilloscope, and OM instrument. The MAC address is located on the OM instrument rear panel label.

NOTE. Make sure to record the IP addresses used for each OM instrument, or

OM5110 User Manual 9

Getting started

If you are setti 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 instrument:

Use LRCP on a PC connected to a DHCP-enabled network (easiest)

Use LRCP on a PC set to the same IP address subnet as the OM instrument to change the OM instrument IP address

Use DHCP network to change instrument IP address. To use a DHCP network to change the IP address of an OM series instrument:

1. Do steps 1 through 6 of the Set network access (DHCP network) procedure.

The OM5110 contains a dual-polarization IQ optical modulator capable of produci 34 Gbaud for small-signal modulation. The optical modulator translates the RF input signals to the frequency of the Optical Input using dual nested Mach-Zehnder modulators to provide RF IQ modulation on two orthogonal polarizations at the Optical Output.

The linear two-stage ampliﬁers increase the RF input signals by 20 dB before going to the modulator. The ampliﬁer gain reduces the input-referred Vpi voltages of the modulators to approximately 350 mV. Full-amplitude bina 700 mVpp but no more than 1 Vpp is required for complete saturation.

The optical bias controller makes sure that each of the data modulators and IQ-phase control modulators are biased at the proper points for IQ modulation. Each IQ RF-input pair should have minimum correlation to

ain the best result with automatic optical bias control. For example, putting

obt exactly the same signal on I and Q will not necessarily result in the expected IQ modulation unless manual optical bias control is used.

There are two primary modes of operation for the OM5110: large-signal and small-signal. Large-signal modulation occurs from around 500 mVpp to where the ampliﬁer is completely saturated at 1 Vpp. In this range both the ampliﬁer and modulator have a nonlinear characteristic that provide higher quality modulation for binary signals. As the ampliﬁer becomes saturated, use the LRCP software to adjust the amplitude and duty-cycle distortion (crossing-point) provided by the ampliﬁer’s second stage of gain. Factory settings provide 2Vpi modulation amplitude and 50% crossing point, but you can adjust these to accommodate different signal sources.

The OM5110 is controlled by the LRCP software. The LRCP automates locating and conﬁguring all OM devices on the network. It also provides a Windows Comm local or remote process to operate the connected devices for ATE (automated test equipment) applications. The LRCP program can control any number of OM-series devices including the OM4000 and OM2000 series and the OM5110.

Each device that the LRCP controls is assigned a tab that is labeled with the device name and IP address. Clicking on the tab brings the control pane for that device to the front. The contents of the control pane depend on that tabs device. The following ﬁgure shows the pane for the OM5110.

The very ﬁrst time the LRCP connects to an OM5110, there is a delay while the LRCP calculates the initial modulator parameters so that they may be stored away in the LRCP Program Files directory. The modulator parameters, including null voltages and Vpi voltages for the various modulator sections, are needed to obtain

roper optical bias for the modulator. The LRCP saves the current state of each

p OM5110 on ﬁrst connection so that you c an restore the parameters if needed. More information on setting the modulator parameters using the “Set Params” button may be found below.

Once the controller tab is active and the panels have populated with information received from the devices, you can change settings and turn on the laser if required. When the controller establishes the connection with the OM4000 series or OM5110 devices, it reads and displays the current state of the device in the panel. Any time you exit the application, the current state of the device is preserved by the device, including the emission state. If the device is powered down, it will return to its default power-on state when it is switched back on.

The service (basic and advanced) interface was developed for incorporation into an ATE client application that you can develop in your choice of .NET language, typically C# or VB.NET. Both services expose most of the functionality that is available through the LRCP’s user interface.

The basic service, implemented using a wsBasicHTTPBinding, exposes the same subset of commands as the advanced service. It was implemented using asimp page 37, ATE functionality in MATLAB.) or Labview that only support the wsBasicHTTPBinding. The basic service is referenced at the following URL: http://localhost:9000/LaserReceiverControlPanel/Laser_ReceiverServiceBasic/

The advanced service, implemented using a wsHTTPBinding, (and which is not available in MATLAB) was developed for use with an ATE client application and uses events to provide a time-efﬁcient interface.

interfaces and show their functionality using the MATLAB syntax.

int Available

Lasers(classname);

Description: Returns the count of available lasers on the active controller. Controller T Example:

ypes: All

AvailableLasers(Obj);

Returns: ans = 2

bool Calibrate();

Descripti

on: Performs an automatic modulator calibration to determine the optimal modulator parameters. These are the same parameters that are manually set using the user interface Set Params button, or the SetManualCalibration() function.

Calibrate() is an automatic calibration that requires the modulator control mode (see GetActualModulatorMode()) be set to 2-pol QPSK and that >500 mVpp binary signals are applied to all four inputs. Longer patterns are better (2 PRBS is optimal). Each of the four input patterns should be different in some way: a

different pattern, the same pattern delayed, or a different seed.

The modulator must receive adequate input power levels to produce a signal power

that is high enough to avoid a power level warning. If these conditions are not met the resulting calibration can result in unstable optical bias. See the section on Set Paramaters to restore these values to initial (factory) values. Controller Types: OM5110 Example:

Calibrate(Obj);

Returns: ans = true/false
