16. AC amplitude accuracy:
17. AC amplitude accuracy:.
18. AC amplitude accuracy:
19. Level is limited by the selection of power supply rails.
20. Accuracy figures are given for a measurement of wideband noise applied to the Tip and Ring port and measured with any of the optional noise filters. The accuracy figure relates the rms noise
21. The accuracy figures provide the tolerances to be applied to the sum of the nominal transmit path and receive path frequency response computed by WinSLAC for the AC profile and the load
22. The accuracy figures provide the tolerances to be applied to the nominal transmit path frequency response computed by WinSLAC for the AC profile and the signal source impedance used
23. The accuracy figures provide the tolerances to be applied to the nominal receive path frequency response computed by WinSLAC for the AC profile and the load impedance used during the test.
24. The maximum peak-to-peak signal amplitude is reduced as the frequency increases because the maximum rate of change must be limited to 250 V/ms on the Tip and Ring port when using 220

The calibration circuit used for In-Service Calibration is shown in
The Test-In Bus leads are wired to the Calibration Bus leads of Configuration D shown in
The bill of materials for the calibration circuit is listed in
