B-14 BHK-MG (OPR) 022014
B.59 [SOURce:]VOLTage[:LEVel]:TRIGgered[:AMPlitude]? QUERY VOLT:TRIG?
Syntax: Short Form: [SOUR:]VOLT[:LEV]:TRIG[:AMP]?
Long Form: [SOURce:]VOLTage[:LEVel]:TRIGgered[:AMPlitude]?
Return Value: <exp_value> = digits with decimal point and Exponent, e.g., 2.71E+1 for 27.1
Description: Returns value representing voltage value to be programmed by *TRG command established by
VOLT:TRIG command). (See example, Figure B-1.)
B.60 [SOURce:]FUNCTion:MODE? QUERY FUNC:MODE?
Syntax: Short Form: FUNC:MODE? Long Form: [SOURce:]FUNCtion:MODE?
Return Value: VOLT or CURR
Description: Identifies the operating mode of the power supply. VOLT = Constant Voltage mode (CV).
CURR = Constant Current mode (CC). (See example, Figure B-1.)

B.61 STATus:OPERation:CONDition? QUERY STAT:OPER:COND?
Syntax: Short Form: STAT:OPER:COND? Long Form: STATus:OPERation:CONDition?
Return Value: <int_value> 0 to 1313 (1 + 32 + 256 + 1024).
Description: Returns the value of the Operation Condition Register (see Table B-2). The Operation Condition
Register contains unlatched real-time information about the operating conditions of the power supply.
Bit set to 1 = function enabled (active, true); bit reset to 0 = function disabled (inactive, false). (See
example, Figure B-6.)
NOTES: 1. The power supply is assumed to be operating in constant voltage (CV) mode.
2 Examples below are intended only to illustrate command functions. Refer to PAR. 3.3.6 for
programming techniques to optimize performance.
OUTP ON Output enabled.
VOLT 218;CURR 1.1E-1 Power supply programmed to 218V, 0.11A.
VOLT 2.157E2 Power supply programmed to go to 215.7V.
VOLT? Returns 2.157E2, indicating programmed voltage = 215.7V.
VOLT? MAX For BHK 500-0.4MG, returns 500 (500V).
VOLT? MIN Returns 0 (minimum allowable voltage).
VOLT:PROT 2.365E+2 Voltage protection set to 236.5V.
VOLT? Returns 2.157E+2, indicating programmed voltage value = 215.7V.
VOLT:PROT? Returns 2.365E+2, (programmed overvoltage protection = 236.5V
VOLT:PROT? MAX For BHK 500-0.4MG, returns 5.5e+2 (550V).
VOLT 221;CURR 1.1E-1 Power supply programmed to go to 221V, 0.11A.
VOLT? Returns 221.
VOLT:LIM[:HIGH] 300 Voltage limit set to 300V.
VOLT:LIM[:HIGH]? Returns 300.
VOLT 333 Power supply not programmed to 333V., error message -301 posted.
VOLT? Returns 2.21E2.
