Calibration/Compensation Data Measurement Point

OPEN/SHORT/LOAD
Calibration
Connect OPEN, SHORT, and LOAD standards to the
desired reference plane and measure each kind of
calibration data. The reference plane is called the calibration
reference plane.
Low-Loss Capacitor Calibration Connect the dedicated standard (Low-Loss Capacitor) to the
calibration reference plane and measure the calibration data.
Port Extension Compensation
(Fixture Selection)
When a device is connected to a terminal that is extended
from the calibration reference plane, set the electrical length
between the calibration plane and the device contact. Select
the model number of the registered test fixtures in the
4287A's softkey menu or enter the electrical length for the
user's test fixture.
OPEN/SHORT Compensation When a device is connected to a terminal that is extended
from the calibration reference plane, make OPEN and
SHORT states at the device contact and measure each kind
of compensation data.
Data Measurement Points Same as measurement points set in the measurement point
setup display. (Changing the frequency or oscillator level
settings after calibration or compensation makes the
calibration and compensation data invalid.)
Measurement range 0.1 Ω to 100 Ω
Measurement resolution 1 mΩ
Test signal level 1 mA (maximum)
Error correction OPEN/SHORT/LOAD Calibration, OPEN/SHORT
Compensation. (Changing the frequency or oscillator level
settings after the calibration or compensation makes the
calibration and compensation data invalid.)
Measurement uncertainty
[%]
Rdut: DC resistance measurement value [Ω]
Within ±5°C from the calibration temperature.
Measurement accuracy applies when the calibration is
performed at 23°C ±5°C. When the calibration is performed
beyond 23°C ±5°C, the measurement accuracy decreases to
half that described.
