To abort a running pulse_exec pulse test, see dev_abort.
devint does the following:
1. Clears all sources by calling devclr.
2. Clears the matrix crosspoints by calling clrcon.
3. Clears the trigger tables by calling clrtrg.
4. Clears the sweep tables by calling clrscn.
5. Resets GPIB instruments by sending the string defined with kibdefint.
6. Resets the active instrument cards.
Instrument cards are reset in the following order:
1. SMU instrument cards
2. CVU instrument cards
3. Pulse instrument cards (4225-PMU or 4220-PGU)
devint is implicitly called by execut and tstdsl. devclr is implicitly called by clrcon.
The SMUs return to the following states:
• 100 µA and 10 V ranges
• Autorange on
• Voltage source
• 0 V DCV bias
The 4210-CVU returns to the following states:
• 30 mV
RMS
AC signal
• 0 V DCV bias
• 100 kHz frequency
• Autorange on
• Cable length compensation set to 0 m
• Open/Short/Load compensation disabled
The 4225-PMU or 4220-PGU returns to the following states:
• The pulse mode is maintained. For example, if the pulse card is in Segment Arb mode, it will still
be in Segment Arb mode after the devint process is complete.
• 5 V and 10 mA ranges
• If in pulse mode:
 Period of 1.0 µs
 Transition Times (Rise and Fall) of 100 ns
 Width of 500 ns
 Voltage high and low of 0 V
 Load of 50 Ω
• If in segmented arb mode, Start Voltage is 0 V
• If in arbitrary waveform mode, Table Length is 100
