Series 2400 SourceMeter® Quick Start Guide
Section 1: Introduction
NOTE Limit testing using a component handler to perform binning
operations is summarized in the “More testing techniques” section of
this guide. For complete details on all aspects of limit testing, see the
2400 Series SourceMeter User’s Manual, Section 12.
Limit 1 (compliance)
This hardware (H/W) test uses the programmed compliance as the test limit. At or above the test
limit, the source is in compliance. Below the limit, the source is not in compliance.
The test can be set to fail if the source is in compliance or fail if it is out of compliance. If Limit 1
fails, the FAIL message is displayed and the testing process for that DUT is terminated. A pass
condition allows the testing process to the next enabled software test.
For example, assume the SourceMeter is set to output 1mA with 1V compliance. If the DUT is
above 1k
Ω
, the source will be in compliance. If the DUT is below 1k
Ω
, the source will be out of
compliance.
Use the following menu sequence to configure Limit 1:
Press CONFIG > press LIMIT > select H/W LIMITS
After selecting H/W LIMITS, these menu items will be displayed:
CONTROL - Use to ENABLE or DISABLE the test.
FAIL MODE - If you want the test to fail if the source is in compliance, select IN. If you want the test
to fail if it is not in compliance, select OUT.
Limit 2, 3, and 5 through 12 tests
These software (S/W) tests are used to determine if a DUT is within specified high and low
measurement limits. Typically, Limit 2 is set for the widest limits, while additional limit tests are set
for progressively narrower limits.
Use the following menu sequence to configure the software limit tests:
Press CONFIG > press LIMIT > select S/W LIMITS > select the desired limit test
After selecting the desired limit test (i.e., LIM2), these menu options will be displayed:
CONTROL - Use to ENABLE or DISABLE the test.
LOLIM - Use to enter the low limit value. You will then be prompted to enter the bit pattern for
binning operations. Since binning operations are being done at this time, simply press ENTER or
EXIT.
HILIM - Use to enter the high limit value. You will then be prompted to enter the bit pattern for
binning operations. Since binning operations are being done at this time, simply press ENTER or
EXIT.
Limit testing operation
1.
Connect the DUT to the SourceMeter.
2.
Configure the source-measure functions of the SourceMeter.
3.
Select and configure a limit test as previously explained.
4.
Turn the output on.
5.
Press the LIMIT key to enable the test. The pass/fail status of the test will be displayed.
The test can be disabled by again pressing the LIMIT key.
