U1 Send error conditions. See Figure C-2.
U2 Send model number and firmware revision
SYSTem:VERsion?
U3 Send calibration value
CALibration:PROTected:SENSe:DATA?
U4 Send interval
ARM:TIMer?
U5 Send delay
TRIGger:DELay?
U6 Send relative value for current
CALCulate[1]:NULL:OFFSet?
U7 Send relative value for V/I ohms
CALCulate[1]:NULL:OFFSet?
U8 Send voltage source value
SOURce[1]:VOLtage?
U9 Send voltage source status word. See Figure C-3.
