Questionable Data Status Register Group
The Questionable Data Status Register Group monitors SCPI-defined
conditions.
NOTE For this register group, the transition filter is fixed as PTR with all bits
set to ones. This cannot be changed or queried.
Table lists the Questionable Data Status Register bits and briefly
describes each bit.
A detailed description of each bit in the Questionable Data Status
Register Group follows:
• Bits 0-2 are not used.
• Bit 3 (Power). Power Cal is turned off or the Power Cal tables in
EEPROM are defective or missing.
• Bit 5 (Frequency) is a condition bit which indicates that frequency
measurements may be affected by component failures.
