10. The specified tolerance for RSVA and RSVB is 0.5% with a temperature coefficient of resistance of 100 ppm. Stated performance is only validated and guaranteed for the 0.5%, 100 ppm resistor.
11. Additional notes with regards to stated accuracies. Accuracies are set at 95% of the estimated distribution including all BOM component tolerances as documented in the NGCC Hardware
12. Accuracy of VPTL_TID_INWRD_CUR is set by this test.
13. Accuracy of DC voltage level when using VPTL_TID_MONITOR_IV is set by VPTL_TID_OPEN_DC_VOLTAGE.
14. Accuracy of AC voltage level when using VPTL_TID_MONITOR_IV is set by VPTL_TID_OPEN_AC_VOLTAGE.
15. Accuracy of AC current level when using VPTL_TID_MONITOR_IV is set by VPTL_TID_FOREIGN_AC_CURRENT.
The total voltage range is ±1000 V for the sum of AC and DC signals and may be further limited by the protection devices.
Using the two-step method with offset cancellation
Absolute and relative tolerances are cumulative.
The achievable current will be limited by the driver output voltage as a function of the load under test.
Accuracies only apply to a real resistor or to a real capacitor of the exact value of the test load. Resistance and Capacitance measurement accuracies are given for a single element present.
The presence of an impedance in any of the other two branches may cause >50 times this impedance to appear in the branch under test and will degrade the observed accuracy. This is also
true for the branches that are open. Since when performing the 3 element measurement the test will measure all 3 branches, whether the branches are open or not.
Accuracies are given for FFT sizes of 1024 or more.
Accuracies are given for filter integration time of 100 ms or more.
Accuracies are given for testing in the absence of interference from a foreign AC or DC voltage.
The total current range is ±60 mA for the sum of the AC and DC signals.
If a looser tolerance resistor is used, DC voltage and AC voltage measurement accuracies need to be relaxed. For instance, if a resistor with a 1% tolerance and a 200 ppm temperature coefficient
of resistance is used, then widen the accuracies as follows. For No Calibration tests, widen the listed VPTL_TID_OPEN_DC_VOLTAGE and VPTL_TID_OPEN_AC_VOLTAGE accuracies by
0.2%. For Factory Calibration and In-Service Calibration tests, widen the listed VPTL_TID_OPEN_DC_VOLTAGE and VPTL_TID_OPEN_AC_VOLTAGE accuracies by 0.25%. If non-standard
configurations are used, customer must do due diligence with regards to validation.
Design Guide, Doc ID 126583. Calibration circuit has tolerances and temperature coefficients as specified in the Calibration Circuit Parts List. Temperature at Factory Calibration time is 20°C
±10°C. The temperature changes by no more than 20°C between executing the SLAC internal calibration function, executing In-Service Calibration (if applicable), applying the Factory or In-
Service calibration factors (if applicable), and running the test.
