B.69 [SOURce:]VOLTage:[:LEVel]MODE?
QUERY
VOLT:MODE?
Syntax:
Short Form: [SOUR:]VOLT[:LEV]:MODE?
Long Form: [SOURce:]VOLTage[:LEVel]MODE]?
Return Value: FIXED or EXTERNAL
Description:
Returns FIXED or EXTERNAL depending on whether voltage control is from the keypad or
GPIB interface (FIXED or from an external analog reference voltage (EXTERNAL).
B.70 [SOURce:]VOLTage:PROTection[:LEVel] COMMAND
VOLT:PROT
Syntax:
Short Form: [SOUR:]VOLT:PROT[:LEV] <exp_value>
Long Form: [SOURce:]VOLTage:PROTection[:LEVel] <exp_value>
<exp_value> = digits with decimal point and Exponent, e.g., 2.71E+1 for 27.1
Description:
Sets overvoltage protection level for power supply.
If the value is out of the acceptable overvoltage
range for the power supply model, error message -222,”Data out of range” is posted in the output
queue. If the power supply output exceeds the voltage protection level programmed, then the power
supply output is disabled (programmed to 0) and the OV bit in the Questionable Condition status reg-
ister is set. An overvoltage condition can be cleared with the VOLT:PROT:CLE command. The voltage
protection level can be programmed independently of the output voltage level. Setting voltage protec-
tion to a value lower than the output voltage causes the voltage protection mechanism to trigger imme-
diately. (See example, Figure B-6.)

B.71 [SOURce:]VOLTage:PROTection[:LEVel]?
QUERY
VOLT:PROT?
Syntax:
Short Form: [SOUR:]VOLT:PROT[:LEV] MIN, MAX
Long Form: [SOURce:]VOLTage:PROTection[:LEVel] MIN, MAX
Return Value: <exp_value> = digits with decimal point and Exponent, e.g., 2.71E+1 for 27.1
Description:
Identifies overvoltage protection setting, maximum allowable overvoltage protection, or mini-
mum overvoltage protection.
VOLT:PROT? returns value set by VOLT:PROT. VOLT:PROT? MAX
NOTES: 1. Power supply assumed to be operating in constant voltage mode.
2. Examples below are intended only to illustrate command functions. Refer to PAR. 3.6.5 for
programming techniques to optimize performance.
VOLT 21; CURR 1.1
Power supply programmed to 21V, 1.1A.
VOLT 2.157E1
Power supply programmed to go to 21.57V.
VOLT?
Returns 2.157E1, indicating programmed voltage = 2.157V.
VOLT? MAX
For ATE 100-10DM, returns 100 (100V).
VOLT? MIN
Returns 0 (minimum allowable voltage).
VOLT:PROT 2.365E+1
Voltage protection set to 23.65V.
VOLT?
Returns 21.57, indicating programmed voltage value = 21.57V.
VOLT:PROT?
Returns 2.365+E1, (programmed overvoltage protection = 23.65V
VOLT:PROT? MAX
For ATE 100-10DMG, returns 110.
VOLT:PROT:TRIP?
0 indicating overvoltage protection not tripped.
--- OVERVOLTAGE CONDITION OCCURS.
VOLT:PROT:TRIP?
1 indicating overvoltage protection tripped.
VOLT:PROT:CLE
Overvoltage condition cleared.
VOLT:PROT:TRIP?
0 indicating overvoltage condition not tripped.
VOLT?
Returns 0, programmed voltage value = 0V.
VOLT 21; CURR 1.1
Power supply programmed to go to 21V, 1.1A.
VOLT?
Returns 21.
VOLT:LIM:HIGH 5
Voltage limit set to 5V.
VOLT:LIM:HIGH?
Returns 5
.
VOLT 33
Power supply programmed to 5V.
SYST:ERR?
Error message -301 “Value bigger than limit.”
VOLT?
Returns 5.
