Test4: Arb_Select_Wave_By_Name: ‘waveform_name’ = square
Testplan ‘arbdown_name.tpa’ illustrates how to download a 1 kHz sine
wave, 2 kHz square wave, and 4 kHz triangle wave. A review of the testplan
is below.
Test Group/Test/Action Name Description
testgroup Arb download waveforms Downloads standard waveforms.
Switching Connect Arb channel 1 output to ABus1 and UUT Common.
test setup Arb Setup arb output circuitry.
arbConfOutControls Configures Arb’s output circuitry.
arbSet Sends setup data to Arb.
test download sine wave Downloads the standard sine wave to the Arb.
Arb_Dl_Std_Waveform Downloads a sine wave into the Arb. The ‘function’ parameter is set to “0” to
download a sine wave.
The ‘waveform_name’ parameter is set to “sine” to give the downloaded
waveform that name.
The ‘frequency’ parameter is set for a 1 kHz waveform.
The ‘Vpeak’ parameter is set for a 5 V peak waveform.
The ‘waveform_name’ parameter is set to
test download square wave Downloads the standard pulse wave to the Arb.
Arb_Dl_Std_Waveform Downloads a square wave into the Arb. The ‘function’ parameter is set to
“1” to download a pulse.
The ‘waveform_name’ parameter is set to “square” to give the
downloaded waveform that name.
The ‘duty_cycle’ parameter is set to “0.5” so the pulse function
downloads a square wave.
The ‘frequency’ parameter is set for a 2 kHz waveform.
The ‘Vpeak’ parameter is set for a 5 V peak waveform.
test download triangle wave Downloads the standard triangle wave to the Arb.
Arb_Dl_Std_Waveform Downloads a triangle wave into the Arb. The ‘function’ parameter is set to
“2” to download a triangle wave.
The ‘waveform_name’ parameter is set to “triangle” to give the
downloaded waveform that name.
The ‘frequency’ parameter is set for a 4 kHz waveform.
The ‘Vpeak’ parameter is set for a 5 V peak waveform.
test output waveforms This test executes the downloaded waveforms.
arbInitiate Initialize the Arb to output the waveform. Start outputting the waveform. The
Arb at this time outputs the last downloaded waveform (i.e., “triangle”).
DialogOkay This optional action is used here to view the current waveform (i.e., triangle
wave).
Arb_Select_Wave_By_Name Selects and outputs the waveform using the name entered in the
‘waveform_name’ parameter (i.e., “sine”). Since this is the name of the
‘waveform_name’ parameter of the “Arb_Dl_Std_Waveform” action in “test
download sine wave”, a sine wave is output by the Arb.
DialogOkay This optional action is used here to view the current waveform (i.e., sine
wave).
