DC Gain Accuracy
This test checks the DC gain accuracy of the probe. If the measurements are out of the speci
fi
ed limits in the test record, refer to
the
Adjustments
section. (See page 57.)
1.
Connect a BNC-to-Dual Banana adapter to
the digital multimeter (DMM) input.
2.
Connect the SMA M-to-BNC-F adapter
to the SMA output of the TekVPI
Calibration/Veri
fi
cation adapter.
3.
Connect the BNC cable between
the BNC adapter on the TekVPI
Calibration/Veri
fi
cation adapter and the
BNC adapter attached to the DMM.
4.
Connect the TekVPI Calibration/Veri
fi
cation
adapter to any channel (1–4) of the
oscilloscope.
5.
Connect the TPA-BNC adapter to the
TekVPI Calibration/Veri
fi
cation adapter.
NOTE.
The adapters are only used to supply
power to the probe; measurements are taken
on the DMM.
