SML 007 — Leakage Current Test
•
V, Measure I.
•
Limit 2 test – Min/max limits for current reading.
•
Summary – This test is the same as the test at memory location 004, except the
source voltage is reversed to properly bias the diode that was installed backwards.
Test results — The test results for the 4-point source memory sweep are stored in the
buffer. Stored readings are accessed by pressing the RECALL key. Each of the four read-
ing numbers are preceded by a “P” or an “F” to indicate the “Pass” or “Fail” result of the
corresponding test. See
Section 9
for details on the data store.
Configuring and running a sweep
Front panel sweep operation
Sweep configuration menu
The sweep configuration menu is structured as follows and is shown in
Figure 10-7
. Note
that bullets indicate the primary items of the sweep menu and dashes indicate the options
of each menu item. Using
Section 1
, “
Rules to navigate menus
,” go through the following
menu to select and configure the desired sweep.
CONFIGURE SWEEPS menu:
Press CONFIG then SWEEP to display the sweep configuration menu.
•
TYPE — Use this menu item to select the type of sweep:
–
STAIR — When the linear staircase sweep is selected, you will be prompted to
enter the START, STOP, and STEP levels.
–
LOG — When the logarithmic staircase sweep is selected, you will be
prompted to enter the START and STOP levels and specify the number of
measurement points.
–
CUSTOM — With the custom sweep selected, you specify the number of
measurement points (# POINTS) in the sweep and the source level at each
point (ADJUST POINTS). With the INIT option, you can set a consecutive
range of measurement points in the sweep to a specific level. For example,
assume that for a 20-point custom voltage sweep (# POINTS = 20), you want
points 10 through 15 to be set for 1V. After selecting the INIT option, set the
VALUE to +1.000000V, set the START PT to 10, and set the STOP PT to 15.
–
SRC MEMORY — With the Source Memory Sweep selected, you specify the
memory location START point to start the sweep (1 is the default) and the
number of memory location points (# POINTS) in the sweep. When config-
ured to sweep past point 100, the sweep automatically wraps around to point 1.
