Switch Control Terminals
The N1267A has the Switch Control (MCSMU Force and Sense) terminals for
controlling the N1267A ON/OFF status. Requirements for the terminals are listed
below.
• Control voltage to set the N1267A OFF status: 0 V
• Control voltage to set the N1267A ON status: 15 V
• Current compliance: 100 mA
• Input voltage: 0 V to +18 V
• Voltage limit (input protection): -0.6 V to +20 V
Duration and Sampling Settings
For current collapse measurement (tracer test):
• OFF state duration: 10 ms to 655.35 s, in 10 ms resolution
For current collapse measurement, oscilloscope view or signal monitor:
• OFF state duration: 10 ms to 655.35 s, in 10 ms resolution
• ON state duration for 20 A range: 50 s to 1 ms, in 2 s resolution
• ON state duration for 1 A range and below: 50 s to 2 s, in 2 s resolution
• Sampling duration: maximum 24 ms
• Sampling rate: 6 s for voltage, 2 s to 12 s for current
For current collapse measurement, IV-t sampling:
• OFF state duration: 10 ms to 655.35 s, in 10 ms resolution
• Minimum sampling interval, linear sampling: 200 s
• Maximum number of samples, linear sampling: 100,001/(number of
measurement parameters)
• Sampling mode: linear or log
Transient Response
The N1267A has the transient response as shown in Figure 3-23 due to the internal
circuit of HVSMU. After the N1267A switch status is changed from OFF to ON,
HVSMU current is limited by the internal circuit, and voltage goes down. Finally it
causes the current shift of Current limit change after Current limit period elapsed.
