VXI VT1422A, VT1529A/B The Operation Status Group

VT1422A Command Reference 381Chapter 7
STATus
Weighted Bit
Values
Register queries are returned using decimal weighted bit values. Enable registers can
be set using decimal, hex, octal, or binary. The following table can be used to help
set Enable registers using decimal and decode register queries.
Status System Decimal Weighted Bit Values
The Operation Status Group
The Operation Status Group indicates the current operating state of the VT1422A.
The bit assignments are:
STATus:OPERation:CONDition?
STATus:OPERation:CONDition? returns the decimal weighted value of the bits set
in the Condition register.
Comments •The Condition register reflects the real-time state of the status signals.
The signals are not latched; therefore, past events are not retained in this register
(see STAT:OPER:EVENT?).

0 1 000116 Calibrating Set by CAL:TARE and CAL:SETup. Cleared by
CAL:TARE? and CAL:SETup?. Set while *CAL?
executes and reset when *CAL? completes. Set by
CAL:CONFIG:VOLT or CAL:CONFIG:RES, cleared by
CAL:VAL:VOLT or CAL:VAL:RES.
