Supplemental
characteristics data for
the 42841A
Impedance measurement
accuracy and applicable
measurement range:
The figure to the right shows the inductance
measurement accuracy of the 42841A
measurement system configured for 40 A.
The inductance measurement accuracy
represents the tolerance of additional errors
to the 4284A’s measurement accuracy
and is applicable at the 42842A/B’s
measurement terminals when all of the
following conditions are satisfied:
(1) 4284A integration mode: long
(2) Test signal voltage level: 1 Vrms
(3) Test cable: 16048A
(4) Short compensation has been performed
(5) Surrounding temperature: 5 °C to 45 °C
(6) DUT’s dissipation factor D < 1
The entire system’s measurement error
is given as 4284A accuracy + 42841A
accuracy (see figure) + additional error
due to temperature (see table).
For more information see the operational
manual of 42841A.
Bias current settling time:
The typical time required for the bias
current to reach 99% of setting from 0 A
is given as:
Bias current
≤ 1 A: 1 s + I bias + 0.6 s
Bias current
≤ 5 A: 0.2 s + I bias + 0.6 s
Bias current > 5 A: 0.1 s + I bias + 0.6 s
where I bias is bias current setting in
amperes.
