Sweep Operation 9-11
SML 007 — Leakage Current Test
• Source +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 reading numbers
are preceded by a “P” or an “F” to indicate the “Pass” or “Fail” result of the corresponding test.
See Section 8 for details on the data store.

Configuring a sweep
The sweep configuration menu is structured as follows and shown in Figure 9-7. 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 measure-
ment 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 cus-
tom 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 mem-
ory location START point to start the sweep (1 is the default) and the number of
memory location points (# POINTS) in the sweep. When configured to sweep past
point 100, the sweep automatically wraps around to point 1.
