6-57. Leveled Sine Wave Amplitude Verification

This procedure uses the following equipment:
•
•
•
•
Refer to Figure 6-17 for the proper setup connections.
Set the Calibrator Mainframe to SCOPE mode, with the Levsine menu on the display.
Press O on the Calibrator Mainframe to activate the output. Then follow these steps
to verify the leveled sine wave amplitude.
1. Connect the BNC cable to the Calibrator Mainframe's SCOPE connector. Connect
2. Set the 5790A to AUTORANGE, digital filter mode to FAST, restart fine, and Hi
3. Program the Calibrator Mainframe to output the voltage listed in Table 6-29.
4. Allow the 5790A reading to stabilize, then record the 5790A's rms reading for each
5. Multiply the rms reading by the conversion factor of 2.8284 to convert it to the peak-
6. Multiply the peak-to-peak value by (0.5 * (50 + Rload) / Rload), where Rload = the
