HP-IB Help
The following CDMA Status Register Group bits monitor the status of FER
testing:
•
Test Passed (BCD 1024)
•
Test Failed (BCD 512)
•
Max Frames (BCD 256)
These bits are "event" bits only, which means that no condition registers are imple-
mented. Refer to
"CDMA Status Register Group"
in the Status Reporting chapter of
the HP 8924C User’s Guide for information about using status bits.
