ADC Mode Description
High Speed
ADC
AUTO Number of averaging samples = N × referenc
e
where reference is the number of
averaging samples
automatically set by Agilent B1500; this cannot be
changed.
Specify the N value shown ab
ove. Available values are
1 to 1023. Initial value is 1.
MANUAL Specify the number of averaging samples (N).
Available values are 1 to 1023. Initial value is 1.
PLC Number of averaging samples = N × 128
Specify the N value shown ab
ove. Available values are
1 to 100. Initial value is 1.
Agilent B1500 gets 128 samples in a power line cycle.
Hence, the N valu
e is equal to the number of power line
cycles.

AUTO Integration time = N × reference
where reference is the integr
ation time automatically
set by Agilent B1500A; it cannot be changed.
Specify the N value shown ab
ove. Available values are
1 to 127. Initial value is 6.
MANUAL Integration time = N × 80 μsec
Specify the N value shown ab
ove. Available values are
1 to 127. Initial value is 3.
PLC Integration time = N / power line fr
equency
Specify the N value shown ab
ove. Available values are
1 to 100. Initial value is 1.
The N value means the number of power line cycles.
