Checking the Environment Requirements

Read this section before attempting any installation procedures. This section describes site considerations and power requirements for your data timing generator.

Site Considerations

The data timing generator is designed to operate on a bench in the normal position (on the bottom feet). For proper cooling, at least three inches (7.62 cm) of clearance is required on both sides of the data timing generator, and the bottom requires the clearance provided by the mainframe feet.

If you operate the data timing generator in the Master-Slave mode, you can stack up to two mainframes.

CAUTION. To avoid damage to the mainframe, always close the bottom stands when you stack the mainframes.

Using a cart is not recommended when you stack the mainframes. Doing so could result in serious damage to the cart or mainframes.

Do not operate the mainframe while it rests on its left side feet. Always place the mainframe in the normal position (on the bottom feet) while the mainframe powered-on.

Data Structure

Logical Channel

Physical Channel

The data timing generator has two types of channels: logical and physical. Logical channels represent one-bit pattern data. The number of logical channels is 32 (= 4 channels x 8 slots) for the DTG5078, or 8 (= 2 channels x 4 slots) for the DTG5274.

Logical channels themselves do not have the concept of length. The length of the pattern data on a logical channel is the block size defined in the Blocks window. Each piece of the pattern data has a value of 0 or 1. To create the pattern data, you can use the Data-Listing or Data-Waveform window.

One of the key features of the data timing generator is that each logical channel has its attribute value of the output setting parameters such as the output level, pulse width or delay time. You can set these parameters using the Level and/or Timing windows.

Physical channels are defined as the hardware channels of an output module installed in the data timing generator mainframe. Each of the DTGM10 or DTGM20 output module installed in the DTG5078 mainframe has four physical channels. Each of the DTGM10 or DTGM20 module installed in the DTG5274 mainframe or each of the DTGM30 module installed in the DTG5078 or DTG5274 mainframe has two physical channels.

The number of physical channels available for the system is determined by the mainframe type and the types and number of output modules installed.

The DTG5000 software has the output setup parameters, such as the output level or clock frequency, in its logical channels. To perform the actual data pattern outputs, do the following:

H First, specify the physical channels to output the data within the logical

channels.

H Next, send the output setup parameter to the physical channels to operate the

hardware properly.

To associate the logical channel with the physical channel (this is also called channel assignment), use the Channel Group window. Refer to Window Operation 4: Channel Group Window on page 2--42.

DTG5078 & DTG5274 Data Timing Generator User Manual

Data Structure

Groups

Blocks

A group is defined as a set of logical channels. Grouping function is especially useful depending on the DUT. Several channels are sometimes used with the same output level and data format. In such case, handling the multiple channels as one group is a useful method.

The number of logical channels that the system can accept is determined by the mainframe (32 for the DTG5078 or 8 for the DTG5274). In the Master-Slave operation mode, the number increases with the number of mainframes. The number of groups depends on how many groups the user divides the logical channels. The total number of logical channels of each group cannot exceed the number of logical channels that the system can accept. By default, every logical channel is divided into an eight-channel group. To add a new group, you have to delete some groups or decrease the number of logical channels in a group to secure the logical channels required for the new group.

To create, delete, rename or resize a group, use t he Channel Group window.

A block is defined as a set of groups that consist of logical channels. The block is an elementary data of signal output. To specify the block length, use the block size located in the Blocks window. The block size represents the pattern data length, or vector length. The block width is the sum of bit width in the group to which it belongs, that is, the total number of logical channels.

Sequence

By default, one block whose size is 1000 named Block1 is created.

Creating multiple blocks enables you to perform the repetitive signal outputs by the blocks or sequential outputs with jumps. Even if two or more blocks exist in the system, only one method can be used for either grouping or channel assignment.

To create, rename or resize a block, use the Blocks window.

Use the Data-Listing or Data-Waveform window to edit values (0 and 1) in the individual pattern data. Editing is possible by the block unit. To specify the block to be edited, you can use Select Block... from the Edit menu of the Data-Listing or Data-Waveform window, or use View Data-Listing or View Data-Waveform from the Edit menu of the Blocks window.

To set the voltage output setting parameter, use the Level window. To set the timing output setting parameter, use the Timing window. Both parameters can be set by the channel unit (except for clock frequency), not by the block unit.

A sequence consists of blocks and subsequences. As the subsequence elements, one or more block names and the repetition of the blocks are defined. Using a sequence, you can output the complex signals by defining blocks, number of repetition of subsequence, and jump conditions.

Grouping and Channel Assignment

Grouping is to collect channels in a single group to enable setup, edit or display by group. To define a group or perform a channel assignment, use the Channel Group window. You can use the grouping function only in the Data Generator mode.

Data Structure

Defining a Group

Assigning a Channel

A group is defined by the name and the channels included in the group. The defined group and channels are used for display by the channel or by the group in the Data-Listing, Data-Waveform, Timing, or Level window.

The channels to be defined are logical channels but not physical channels, which are actually installed to the hardware. The pattern data you created by pattern edit and the setting parameters such as the voltage and/or delay are attributes with logical channels.

To output a signal, you must assign the previously defined logical channels to physical channels. See Figure 3--3.

H Assign only one physical channel to one logical channel.

H Channel assignment can be performed, regardless of the bit sequence in the

group; any physical channels can be assigned to logical channels as desired.

H You can define the logical channels without being assigned to physical

channels.

H The physical channels that are not assigned to the logical channels do not

output any signals.
