Description Similar SCPI
Command
TEST? This command causes the dc source to run selftest and report
any detected failures.
Data Representation: ZZZZD
*TST?
UNMASK
xxx
These commands determine the conditions that will set bits in
the fault register, allowing the operator to define the conditions
that will be reported as fault Fault conditions can be enabled by
sending the decimal equivalent of the total bit weight of all
conditions to be enabled.
STAT:OPER:ENAB
STAT:QUES:ENAB
*ESE
VOUT? This command measures and returns the actual output voltage.
Data Representation: SZZD.DD; (SZD.DDD for 6634B only)
MEAS:VOLT?
VSET <n> This command programs the output voltage. See Table 8-3 for
the programming range of this command.
Initial condition: 0 V
VOLT
A = Alpha
D = Digit
S = Sign (blank for positive and – for negative)
Z = Digit with leading zeros output as spaces
