Status Bit Descriptions
Questionable Data Group
Bit Bit Value Event Name Description
8 256 Lost Calibration At *RST or Power-on Control Processor has found a checksum error in
the Calibration Constants. Read error(s) with SYST:ERR? command
and re-calibrate areas that lost constants.
9 512 Trigger Too Fast Scan not complete when another trigger event received.
10 1024 FIFO Overflowed Attempt to store more than 65,024 values in FIFO.
11 2048 Overvoltage
(Detected on
Input)
If the input protection jumper has not been cut, the input relays have
been opened and *RST is required to reset the module. Overvoltage will
also generate an error.
12 4096 VME Memory
Overflow
The number of values taken exceeds VME memory space.
13 8192 Setup Changed Channel Calibration in doubt because SCP setup may have changed
since last *CAL? or CAL:SETup command. (*RST always sets this bit.)
Operation Status Group
Bit Bit Value Event Name Description
0 1 Calibrating Set by CAL:TARE and CAL:SETup. Cleared by CAL:TARE? and
CAL:SETup?. Set while *CAL? executing, then cleared.
4 16 Measuring Set when instrument INITiated. Cleared when instrument returns to
Trigger Idle State.
8 256 Scan Complete Set when each pass through a Scan List is completed
9 512 SCP Trigger Reserved for future SCPs
10 1024 FIFO Half Full FIFO contains at least 32,768 values
11 2048 Algorithm Interrupt The interrupt() function was called in an executing algorithm
Standard Event Group
Bit Bit Value Event Name Description
0 1 Operation Complete *OPC command executed and instrument has completed all pending
operations.
1 2 Request Control Not used by VT1419A
2 4 Query Error Attempting to read empty output queue or output data lost.
3 8 Device Dependent
Error
A device dependent error occurred. See Appendix B.
4 16 Execution Error Parameter out of range or instrument cannot execute a proper command
because it would conflict with another instrument setting.
5 32 Command Error Unrecognized command or improper parameter count or type.
6 64 User Request Not used by VT1419A
7 128 Power-On Power has been applied to the instrument
