Section 3
Vector Output Operation
INTRODUCTlON 3.1.
This section describes the general functions of the Vector Output
I/O Module. Each of these functions are covered more fully in
the Sections that follow.
CLOCK SELECTION 3.2.
The Vector Output I/O Module can be synchronized to a number
of different clock sources, both external and internal.
There are several methods of synchronizing the Vector Output
I/O Module to the UUT. To synchronize vector driving with a
UUT clock, the DR CLK input of the Vector Output I/O Module
can be connected to a UUT clock source. The
syncoutput
command would then be set to “drclk”. To synchronize re-
sponse gathering with a UUT clock, connect the Vector Output
I/O Module CLOCK input (yellow lead) to the UUT clock
source and set the
sync command to “ext”.
To synchronize the UUT to the Vector Output I/O Module, con-
nect the UUT clock input to INT CLK and set the
syncoutput
command to “intfreq”. Use the clockfreq command to select ei-
ther 1, 5, 10, or 20 MHz as the clock rate. If the delay between
INT CLK and the vector data output is too long, dedicate one
output line in the 40-pin connector of the Vector Output I/O
Module as the clock input to the UUT and program that line (in
the vector file) to perform as a clock.
