Option
Description
Resolution
The ammeter resolution value in Ampere units.
Samples
The number of samples that the ammeter will read and average. 1 to 1000 is
supported.
SCPI cmd
A SCPI command to be passed to the ammeter just before the measurement is
taken. Supports multiple commands separated with a column. Up to 256 characters
are supported.
Upper limit
The upper limit value of the peripheral current measurement test procedure, for a
single DUT.
Next to this input field the total upper limit current consumption for all the enabled
DUTs is shown, which is the value to be used during testing.
Note:
During testing, some DUTs may fail until the current measurement test takes
place. In that case, the PLT will automatically re-calculate the total upper limit by
using the value given for a single DUT multiplied with the number of the active DUTs
at the time that the test will run.
Low limit
The low limit value of the peripheral current measurement test, for a single DUT.
Next to this input field the total upper limit current consumption for all the enabled
DUTs is shown, which is the value to be used during testing.
Note:
During testing, some DUTs may fail until the current measurement test takes
place. In that case, the PLT will automatically re-calculate the total low limit by using
the value given for a single DUT multiplied with the number of the active DUTs at the
time that the test will run.
Test Options
Select between a PWM GPIO test and custom test.
Note:
For the custom tests to work, a modified production test firmware must be
created with tests that set the DUTs to specific states before the current
measurement test. Each test must be assigned to a specific opcode. The custom
tests are the exact same as in Section
Test Options - GPIO
Pin
Sets the GPIO to toggle with the PWM pulse.
GPIO state
Sets the active state of the GPIO.
GPIO power level
Sets the power level of the GPIOs.
PWM frequency
Sets the PWM frequency.
PWM duty
Sets the PWM duty cycle.
Test Options
–
Custom Test
Start Command ID
The opcode of the custom test that sets the state of the DUT.
Stop Command ID
The opcode of the custom test that restores the DUT to its
original state.
Table 48: Current Measurement Test - Sleep Current Measurement
Option
Description
Enable
This option enables the sleep current measurement using the ammeter provided in
the
Instrument
section.
Single Device
If this option is enabled, PLT will measure the current consumption, one device at the
time. Initially, it will power off all DUTs. It will then power on one by one, download
firmware and measure the current individually. This procedure takes a lot of time. It
should only be used for production setup purposes, to identify the correct limits by
measuring multiple DUTs and taking the average.
Sleep mode
User can select either the Extended or the Deep sleep mode.
Shunt resistor
The value of the shunt resistor used for sleep current measurement. Applicable only
if a voltmeter or a NI-DAQ is used to measure current instead of a DMM. Values from
0 to 9999 are supported.
