Overview

Product Overview

The MU181040A is a plug-in module that can be built into the host computer of the signal quality analyzer series. It can measure a variety of samples within the operating frequency range, including PRBS samples, data, zero shift, mixed and sequential samples. This module is therefore useful for research, development and production of various types of digital communication equipment, modules and devices.

Support a variety of applications such as research, development and device manufacturing by installing options.

Panel Layout and Connectors

Panel Layout
Inter-Module Connection

Make sure you are using the 3-pin power cord that came with the host computer and the 3-pin power outlet. Connect the MU181020A data output connector and the MU181040A data input connector with a coaxial cable. Also connect the XData MU181020A output connector and the XData MU181040A input connector with a coaxial cable.

Connect the output connector of the MU181020A clock and the input connector of the MU181040A clock with a coaxial cable. Please note that after initialization, all settings are returned to the initial factory settings. In order to protect the device from failure due to electrostatic discharge, a conductive plate should be installed on the work table, and the operator should wear an electrostatic discharge wrist strap.

Connect the ground end of the wrist strap to the circuit board or to the main computer's ground terminal. When removing the cable from the connector on the front panel of the device, be careful not to put too much stress on the connector.

The setting items change according to the item selected in the drop-down list (“1” in the figure above) in the item setting area. The display items change according to the item selected in the drop-down list ("2" in the image above) in the results display area. This section describes the setting items when Gating is selected from the drop-down list in the item setting area ("1" in Figure 5.1-1).

1] Select the measurement period unit from the Unit list box and set the measurement period in the upper right text field. Select “Progressive” or “Immediate” from the Calculation list for the method of displaying measurement results in the middle. This section describes the setting items when Auto Sync is selected from the list box in the item setting area (“1” in Figure 5.1-1).

If the error rate exceeds the synchronization threshold in the synchronization gain condition, it is evaluated as a synchronization loss. On the other hand, if the error rate falls to the synchronization threshold or below the synchronization loss condition, it is evaluated as synchronization gain. This section describes the setting items when Sync Control is selected from the list box in the item setting area (“1” in Figure 5.1-1).

The test pattern synchronization methods that you can select from the Control list box vary depending on the test pattern selected on the Pattern tab. The frame detection pattern length varies depending on the test pattern selected in the Pattern tab window. This section describes the setting items when Condition ("1" in Figure 5.1-1) is selected from the list box in the item setting area.

This section describes the setting items when Input is selected from the list box in the subject setting area (“1” in Figure 5.1-1). The setting range of the setting points is limited by the input conditions specified in the Input tab window. This item is enabled when "Differential 50 Ohm" or "Differential 100 Ohm" is selected and "Alternative" is selected in the Input tab.

This section describes the setting items when Logging is selected from the list box in the results display area ("2" in Figure 5.1-1). The functions of the controls in the Bit Window Setup dialog box are as follows. The number of blocks in the pattern data edited in the Pattern Editor dialog box is displayed.

The length of 1 row of the pattern data edited in the Pattern Editor dialog box is displayed. The length of the data pattern edited in the Pattern Editor dialog box is displayed. The number of rows per block of the pattern data edited in the Pattern Editor dialog box is displayed.

3] Sets the test pattern for the block selected in the sequence pattern setting display area. 5] Set the pattern to be used for pattern matching in the pattern matching settings area. The Pattern Editor dialog box appears when [Edit] or [Pattern Edit]. in the case of a sequence pattern) you click.

The highlighted part in the Pattern View area can be edited in this dialog box. How to create and edit a test pattern in the Pattern Editor dialog box is described below. 1] Select the display format from the Format list box in the Pattern Editor dialog box.

1 Replaces the cursor position bit or bits in the selection area to "1". Reverse Reverses the cursor position bit or bits in the selection area. In the Model tab window, input test model data can be captured on the MU181040A.

This section describes how to capture and analyze a test pattern in the Sample tab window. A manual trigger can be executed when "Manual" is selected in the Trigger list box in the Status Setup dialog box. 4] Clicking [Set All] selects all check boxes of valid slots in the slot range.

The status of the automatic adjustment is displayed in the lower part of the results tab window.
