Specifications

Hardware

For MCSMU

• Width: 10 s to 100 ms (1 A range), 10 s to 2 s (10 A to 100 mA ranges),

2 s resolution

Recommended pulse width:  50 s (time to reach within 1 % of the final

value at resistive load  50 , 10 V step voltage, and 1 A compliance,

supplemental characteristics)

• Period: 5 ms to 5 s, 100 s resolution

• Pulse duty:

For 1 A range:  5 %

For 10 A to 100 mA ranges:

Period  Width+Delay+2 ms (when Width+Delay  100 ms)

Period  Width+Delay+10 ms (when Width+Delay > 100 ms)

• Delay: 0 to (Period-Width) s, 2 s resolution

• About measurement accuracy

• RF electromagnetic field and SMU measurement accuracy

Voltage and current measurement accuracy may be affected by RF

electromagnetic field of strength over 3 V/m at frequencies 80 MHz to

GHz and 1.4 GHz to 2.0 GHz, and 1 V/m at frequencies 2.0 GHz to 2.7

GHz. The extent of this effect depends upon how the instrument is

positioned and shielded.

• Induced RF field noise and SMU measurement accuracy

Voltage and current measurement accuracy can be affected by induced RF

field noise strengths greater than 3Vrms in the frequency range of 150 kHz

to 80 MHz. The extent of this effect depends upon how the instrument is

positioned and shielded.
