VII- Scan Profiles

Scan Profile
A is a collection of hardware settings which control the electrical signals applied to the IC under test during the
scan. These include voltage, frequency, waveform and source resistance. Each profile has a name which loosely describes the
type of components that could be tested with this profile.
However, the SENTRY software provides an automatic setting which uses an optimised
components to be tested. This setting is strongly recommended. The AUTOMATIC scan profile uses both the High Sensitivity
and High Speed profiles successively, therefore generating two PinPrints per pin for increased test coverage.

Some of the features provided in this section include :
 The Add button. Clicking this button allows you to add a profile to the library. See section 0 for more information.
Copy
 The button. This button allows you to add a copy of the selected profile to the library - see section 0 for more
information. Note this button is only enabled if a profile is selected in the profile list (Error! Reference source not
found.).
Delete
 The button. This button allows you to remove a profile from the library. Note this button is only enabled if a
profile is selected in the profile list.

conjunction with the peak voltages (see below) during the scan.
 The Low Peak Voltage
the selected base voltage range.
High Peak Voltage
 The
value of the selected base voltage range.
Waveform
 The : This is the waveform used during the scan. We recommend using only sine waves for this setting.
 The Source resistance
1k, 10k and 100k are available, but we recommend using 1k or 10k for best results particularly when performing
comparisons.
Frequency
 The : This is the frequency of the signal used for the scan, and can be set from 100Hz to 5kHz in a 1-2-5
sequence. For the most accurate results, use the lowest frequency, but you can increase scan times by using a higher
frequency on higher pin count devices at the expense of a loss of comparison accuracy.
