FIGURE B-1. PROGRAMMING THE OUTPUT
B.5 MEASure[:SCALar]:CURRent[:DC]? QUERY
MEAS:CURR?
Syntax: Short Form: MEAS[:SCAL]:CURR[:DC]? Long Form: MEASure[:SCALar]:CURRent[:DC]?
Return Value: (digits with decimal point and Exponent)
Description: Measures actual current. This query returns the actual value of output current (measured at the out-
put terminals) as determined by the programmed value of voltage and current and load conditions.
(See example, Figure B-1.)
B.6 MEASure:VOLTage[:SCALar][:DC]? QUERY
MEAS:VOLT?
Syntax: Short Form: MEAS[:SCAL]:VOLT[:DC]? Long Form: MEASure[:SCALar]:VOLTage[:DC]?
Description: Measures actual voltage. This query returns the actual value of output voltage (measured at the out-
put terminals) as determined by the programmed value of voltage and current and load conditions.
(See example, Figure B-1.)
B.7 [SOURce:]CURRent[:LEVel][:IMMediate][:AMPlitude] COMMAND
CURR
Syntax: Short Form: [SOUR:]CURR[:LEV][:IMM][:AMP]
Long Form: [SOURce:]CURRent[:LEVel][:IMMediate][:AMPlitude]
= digits with decimal point and Exponent, e.g., 2.71E+1 for 27.1
NOTE: Power supply assumed to be operating in constant voltage mode.
