CALibration
• Failure Information for +1 return: The FIFO buffer will contain pairs of values.
The first value will be the failing channel and the second value is the Failure
Code for that channel. Failure Codes found in the FIFO buffer are:
a. Offset exceeds limit. Failure code is 1000.0 + (the offset measured)
b. Gain error exceeds limit. Failure code is 2000.0 + (ideal gain - actual gain)
• Immediately after CAL:REM?, the new calibration constants are used for
subsequent measurements but are in volatile memory. Where these calibration
values need to be retained for long periods, they can be stored into non-volatile
memory using the CAL:REM:STORE command.
• Send with VXIplug&play Function: hpe1422_cmdInt16_Q(...)
CALibration:REMote:DATA
CALibration:REMote:DATA <cal_data_block> restores the remote calibration
constants acquired using the CAL:REM:DATA? query after a remote calibration
operation. These calibration constants go into effect immediately.
Parameters
Comments • CAL:REM:DATA sends to the VT1422A a definite length block of 1024 float64
values that represent an offset and gain pair (in that order) for each of 512
possible remote channels. The block must always be 1024, float64 values
(8192 bytes) regardless how many RSCUs are actually connected to the
VT1422A. Values for channel positions that are not installed are "place holders."
• *RST Condition: Stored calibration constants are unchanged
• Send with VXIplug&play Function: hpe1422_sendBlockReal64(...)
