Preface
This document helps customers with data security concerns to sanitize or remove memory devices from the Tektronix
OM5000, OM4000, and OM2000 Series Optical Modulation instruments.
These products have data storage (memory) devices. These instructions tell how to clear or sanitize the memory devices
and disable the data output devices. The instructions also tell how to declassify an instrument that is not functioning.

purpose of clearing data, putting the instrument in Standby mode does not qualify as powering off. For these products,
you need to either press a rear-panel OFF switch or remove the power source from the instrument.
Remove.
Sanitize.
This is a physical means to clear the data by removing the memory device from the instrument.
This eradicates the data from media/memory so that the data cannot be recovered by other means or
technology. This is typically used when the device is moved (temporarily or permanently) from a secured area to
a nonsecured area.
Scrub.
User Accessible.
User-modifiable.
This is equivalent to sanitize.
User is able to directly retrieve the memory device contents.
The user can write to the memory device during normal instrument operation, using the instrument
interface or remote control.

Data is lost when the instrument is powered off.

representing signals connected to the instrument by users.
User settings – Describes the type of information stored in the device. Refers to instrument settings that can be
changed by the user.
Both – Describes the type o f information stored in the device. It means that both user data and user settings are
stored in the device.
None – Describes the type of information stored in the device. It means that neither user data nor user settings
are stored in the device.
Directly – Describes how data is modified. It means that the user can modify the data.
Indirectly – Describes how data is modified. It means that the instrument system resources modify the data and that
the user cannot modify the data.

RF Amplifier Bias board
(OM5110 only)
The RF Amplifier Bias Board uses 16 digital potentiometers which retain their values using 15 bytes of data. These
cannot be cleared or sanitized by the end user. You can replace the data stored in the RF Amplifier Bias Board with a
generic configuration following this procedure:
1.
Connect to the OM5110 using the LRCP software.
2.
Record the settings in the Driver Amp area if it is desired to restore these settings later.
3.
In the Driver Amp area of the LRCP control panel, select Voltage Settings/ Restore to Factory Defaults.
4.
In the Driver Amp area of the LRCP control panel, select Voltage Settings/ Save current settings as power on defaults.

Clear and sanitize procedures
The RF Amplifier Bias Board also stores the prior use-state of the instrument. This can’t be cleared or sanitized, but you
can make the prior-use state generic by following this procedure:
1.
Connect to the OM5110 using the LRCP software.
2.
In the Modulator control area, check the box called Auto Set.
3.
Set up the Modulator control values as shown in the following image.

Troubleshooting
How to clear or sanitize a nonfunctional instrument
If your instrument is not functioning, perform the following actions and return the instrument for Tektronix for repair.
Describe the initial problem with the product. Tektronix will install replacement parts and then repair and return the
instrument.
Board removal guidelines:
Removal and installation should only be performed by trained personnel.
Perform this procedure in a static controlled work area with proper operator grounding.
Disconnect the AC line cord. Board removal procedures expose the technician to AC wiring.
Microcontroller board
Tektronix OM5000, OM4000, OM2000 Declassification and Security Instructions 9
Remove the microcontroller board and return the product to Tektronix. A new microcontroller board will be installed, and
the instrument will be repaired and adjusted as necessary.
To remove the microcontroller board:
1.
Disconnect the AC line cord and observe all warnings in the product user documentation.
2.
Remove the instrument cover. The cover should only be removed by trained personnel.
3.
Locate the microcontroller board. The microcontroller board is the board with the Ethernet connector.
4.
Remove the two screws located near the Ethernet connector.
Troubleshooting
5.
Firmly hold the microcontroller board on the left and right sides at the indicated holding points and pull straight up.
Avoid contacting the connector directly above the board (if present).
6.
After removal of the microcontroller board, refer to your company’s internal policies regarding storage or disposal
of the board.

The instrument should be returned with a new microcontroller board programmed at the factory.
1.
Connect to the OM5110 using the LRCP software.
2.
Use the values recorded previously to return the sliders in the Driver Amp control area to their prior values.
3.
If desired to save these values, click Voltages/ Save current voltages as power on defaults.
1.
Connect to the OM5110 using the LRCP software.
2.
Wait for the LRCP to complete downloading settings from the OM5110. To use the new factory settings, the procedure
is complete. To use the old settings recorded before sanitization, continue this procedure.
3.
To restore the prior settings, close the LRCP and move the InitialState.xml file found in C:\Program
Files\TekApplications\LRCPinstallation to a backup location. This file contains the new OM5110 settings as found on
initial connection. Move the file backed up before sanitization to this directory to replace the new one just removed. It
should have the identical filenameandlocationsothatitisfoundbytheLRCP.
4.
Connect to the OM5110 using the LRCP software.
5.
Click Set Params in the Modulator control area.
6.
Click Restore Initial Values on the pop-up dialog box. The values shown should match those previously recorded to
within 0.1 V.
