ACTIONS WHILE RUNNING
• Breakdown and (optionally) arc detection are performed throughout the test. On any failure the pulse is
immediately aborted.
• A UNIPOLAR+ pulse is shown above, a UNIPOLAR- pulse has the same timing but has the opposite voltage
polarity, a BIPOLAR pulse is a pair of opposite polarity pulses (positive first) with no delay between them.
• A delay is enforced following the pulse(s) to allow any stored energy in the 95x or the DUT caused by
asymmetry in the waveform to dissipate.
o After a unipolar pulse of either polarity or after an abnormally terminated bipolar pulse, this delay is
500ms.
o After a normally terminated bipolar pulse, this delay is 40ms.
CONFIGURING
An example PULSE menu is as follows –
Seq 1 Step 1 PULSE
LEVEL: 200.0V
POLARITY: UNIPOLAR+
BREAKDOWN: 150.0mApk
RAMP: 1.0msec
HOLD: 1.5msec
ARC DETECT:4us 10mA
ON FAIL: ABORT SEQ
• LEVEL. Allows the test voltage level to be programmed. For a bipolar pulse, both polarities have
nominally the same voltage amplitude.
o The amplitude of the pulse is not accurately controlled by the 95x during this type. The actual
peak voltage amplitude is displayed for review after a test step has been run, enabling the user
to adjust the peak test voltage for a specific DUT. Alternatively, the 95x can do this semi-
automatically by using the Lead Compensation feature.
• POLARITY. Allows the polarity of the pulse to be selected.
o UNIPOLAR+. A single, positive polarity, pulse of voltage is produced.
o UNIPOLAR-. A single, negative polarity, pulse of voltage is produced.
