Sequoia / Tahoe Series User Manual California Instruments
M447352-01 REV-A 85
9. Enable the output of the Sequoia and measure the output voltage and current of each phase and
calculate the resistance for each phase (make sure that UUT current limit is greater than 50%
rated value of the Sequoia).
10. Query the following command for getting the reference current.
CURR?
11. Verify the reference current is the same as the measured output current or within the current
program accuracy limit of each phase.
12. Make the resistance value 0, the capacitance value “NC” and Set the Inductance value through
the front panel dashboard screen and apply the button refer above image:
Z
L
= V/I
L = V/(I*2𝜋𝑓)
L = 150V / (50% of Rated current * 2𝜋𝑓)
Inductance value in millihenry unit = L * 1000
13. Enable the output of the Sequoia unit and measure the output voltage and current of each phase
(make sure that UUT current limit is greater than 50% rated value of Sequoia).
14. Query the following command for getting the reference current.
CURR?
15. Verify the reference current is the same as the measured output current or within the current
program accuracy limit of each phase.
16. Make the resistance value 0, the Inductance value “NC” and set the capacitance value through
the front panel dashboard screen and apply the button refer above image:
Z
C
= V/I
C = I/(Vω)
C = 50% of Rated current / (150V * 2𝜋𝑓)
Capacitance value in microfarad unit = C * 10^6
17. Query the following command for getting the reference current.
CURR?
18. Enable the output of the Sequoia and measure the output voltage and current of each phase (make
sure that UUT current limit is greater than 50% rated value of Sequoia).
19. Verify the reference current is the same as the measured output current or within the current
program accuracy limit.
