Using the Agilent Technologies 16552A
This chapter provides instructions for using the Agilent Technologies
16522A to generate vectors and patterns for design and test
environments. Two sections comprise this chapter:
•Setting up the proper configurations
•Building vectors and macros
Because the Agilent 16522A operates in much the same way other
modules in the Agilent 16500B/C mainframe, discussions of general
operation have been eliminated from these procedures. If you have
questions of a general nature, refer to the User’s Reference for the
Agilent 16500.
See chapter 5 for installation instructions.
1–2

Setting Up the Proper Configurations
This section discusses setting up the configuration attributes and
parameters of the pattern generator.
If you are reloading existing configurations or downloading ASCII
vector files, refer to the Load operation in the disk drive menus of the
System.
To set up the configuration
1From the Format menu, set the Vector Output Mode to either full or
half channel.
Make this selection first because clock frequencies and available channels are
affected.
In half channel mode, only pods 1, 3, and 5 are used. Only four channels are
available in pod 5.
2Set the Clock Source to either internal or external.
An external clock is used when you need a clock frequency that is not
available internally, or if you need to drive the pattern generator timing with
an external reference.
1–3

3Set the Clock Period for an internal clock or the Clock Frequency for
an external clock.
The external clock frequency information is required to select the
appropriate operating mode. Operating the pattern generator at an external
clock frequency higher than selected will result in erroneous operation.
4Set the Clock Out Delay if a delay is needed.
Setting a delay is useful when using the clock out edge as a read strobe. If
you do not set the Clock Out Delay, the value is uncalibrated.

To build a label
When you build a label, you are grouping channels under a label name and
mapping the selected channels to the probes on the associated pods. A label
may contain up to 32 channels, however, a single channel cannot be used
under more than one label.
For more information on using labels, refer to "Label Assignment" in the
Common Module Operations section of the mainframe manual.
1Select the label’s channel assignment field.
2Select the desired channels.
* (asterisk) = on
.(period) = off
Only the selected channels can output pattern generator signals.
3Select Done.

Building Test Vectors
Once the pattern generator is configured, you will want to build
programs to use in your test system. You build programs in the
Sequence menu. If you have small program segments that are built
from frequently used vectors, they can be built in the User Macros
menu. Once built, they are inserted into the program in the
Sequence menu.
Another way to build programs is to generate them on another
system, then load them as ASCII files. For more information, refer to
"Loading ASCII files" in chapter 6.
1–6

To build a main vector sequence
During a single run, the program vectors in the MAIN SEQUENCE are output
to the system under test in an order of first vector to last vector. The data of
the last vector is then held until run is selected again. During a repetitive
run, the MAIN SEQUENCE loops until stop is selected.
1From the Sequence menu, use the knob to highlight the first data row.
2Select the Insert field once for each line of vectors you want inserted
into the main sequence.
These new lines of vectors provide fields to place data into for each label.
3Select the data field, then type in a data value.
If you will be adding data in many fields, use the Autoroll feature. Refer to
"To use Autoroll" found later in this chapter.

To build an initialization sequence
Use the INIT SEQUENCE to place the system under test into a known
initialization state. Default start and end program vectors are marked INIT
SEQUENCE START and INIT SEQUENCE END. During a repetitive run, the
initialization sequence is only executed the first time the program is run. The
main sequence then loops repetitively.
1From the Sequence menu, use the knob to highlight INIT SEQUENCE
START.
2Select the Insert field once for each new line of vectors you want
inserted into the initialization sequence.
These new lines of vectors provide fields to place data into for each label.
3Select the data field, then type in a data value.
If you are adding data in many fields, use the Autoroll feature. Refer to "To
use Autoroll" found later in this chapter.
To edit a main or initialization sequence
1Using the knob, highlight the vector you want to edit.
2Select the data field you want to edit.
3Select the new instruction or change the data value.

The following hardware instructions types are available:
•Break
•Signal IMB
•Wait Event
•If Event
1Highlight the vector that you want output as a hardware instruction.
2Select the INST field of the highlighted vector.
3Select the desired hardware instruction type.
4If required, select any qualifying actions for the hardware instruction.

To include software instructions in a sequence
The following software instructions are available:
•User Macro
•Repeat Loop
If you are inserting a User Macro and have not yet built the macro, go to "To
build a user macro" later in this chapter. Macros must be built before they
can be inserted. To include these instructions in a sequence, use the
following procedure.
1Highlight the vector that will be output at the time of the instruction.
2Select the INST field.
3Select the desired software instruction to insert.
4If required, select any qualifying actions for the instruction.
