Introduction
Specifications
High Capacitance Mode
The high capacitance mode permits the measurement of devices with capacitances
greater than the normal mode maximum load value of 0.01 F. In high capacitance
mode, the maximum allowed value of the load capacitance is 50 F.
• Voltage output settling time:
Time required to reach within 0.1 % of final value with 4.7 F capacitive load
on a fixed range at specified current limit value.
200 mV and 2 V Ranges: 600 s, at 1 A limit
20 V Range: 1.5 ms, at 1 A limit
200 V Range: 20 ms, at 100 mA limit
• Current measurement settling time:
Time required to reach within 0.1 % of final value after voltage source is
stabilized on fixed range. Vout is 5 V unless noted.
1 A range: 230 ms
10 A and 100 A ranges: 23 ms
1 mA and 10 mA ranges: 0.23 ms
100 mA to 3 A ranges: 100 s
• Mode change delay:
• Delay into High Capacitance mode:
1 A range: 230 ms
10 A and 100 A ranges: 23 ms
1 mA to 3 A ranges: 1 ms
• Delay out of High Capacitance mode:
All ranges: 10 ms
• Noise 10 Hz to 20 MHz (20 V range): 4.5 mVrms
• Voltage source range change overshoot (20 V range or below):
< 250 mV, 20 MHz bandwidth
