B.60 [SOURce:]VOLTage:PROTection:UNDer:STATE[:LEVel] COMMAND
VOLT:PROT:UND:STAT 0
Syntax: Short Form: [SOUR:]VOLT:PROT:UND:STAT[:LEV] 0
Long Form: [SOURce:]VOLTage:PROTection:UNDer:STATe[:LEVel] 0
Description: Clears undervoltage protection error. This error occurs when input voltage is less than
VOLT:PROT:UND level.
B.61 [SOURce:]VOLTage:PROTection:UNDer:STATE[:LEVel]? QUERY
VOLT:PROT:UND:STAT?
Syntax: Short Form: [SOUR:]VOLT:PROT:UND:STAT[:LEV]?
Long Form: [SOURce:]VOLTage:PROTection:UNDer:STATe[:LEVel]?
where = 1 (undervoltage protection error occurred)
0 (undervoltage protection error has not occurred)
Description: Indicates whether an undervoltage protection error has occurred (1) or not (0).
B.62 [SOURce:]VOLTage:TRANsient COMMAND
VOLT:TRAN
Syntax: Short Form: [SOUR:]VOLT:TRAN
Long Form: [SOURce:]VOLTage:TRANsient ,,,
Where:
= = the maximum voltage value of the transient (Volts)
= = time (Seconds) from start to end of transient (0.0005 Second minimum)
= = number of times transient is to be repeated (default = 1, maximum = 65,000)
(optional) = = total time (Seconds) of repeating pulse train (must be at least 0.0005
greater than transient )
Description: Configures a transient voltage pulse that is initiated by SYST:MODE:TRAN (see PAR. B.100).
B.63 [SOURce:]VOLTage:TRANsient? QUERY
VOLT:TRAN?
Syntax: Short Form: [SOUR:]VOLT:TRAN?
Long Form: [SOURce:]VOLTage:TRANsient?
Returns: ,,, (optional) (See PAR. B.62) for definitions.)
Description: Returns the transient voltage pulse parameters established by VOLT:TRAN (PAR. B.62).
B.64 STATus:CHANnel[:EVENt]? QUERY
STAT:CHAN?
Syntax: Short Form: STAT:CHAN[:EVEN]? Long Form: STATus:CHANnel[:EVENt]?
Returns: <16 bits> = the value of the Channel event register.
Description: Returns value of Channel event register. Each PFM within a chassis has three Channel registers
associated with it. Bits in the Event register are set whenever the associated condition occurs, and are
cleared only upon an explicit command, thus latching any conditions that occur. See Table B-2 for bit
assignments.
B.65 STATus:CHANnel:CONDition COMMAND
STAT:CHAN:COND
Syntax: Short Form: STAT:CHAN:COND 0 Long Form: STATus:CHANnel:CONDition 0
Description: Resets the Channel Enable Register bits to zero.
