6-59. Leveled Sine Wave Harmonics Verification
This procedure uses the following equipment:
• Hewlett-Packard 8590A Spectrum Analyzer
• BNC(f) to Type N(m) adapter
• BNC cable supplied with the SC600
Refer to Figure 6-9 for proper setup connections.

Figure 6-9. Leveled Sine Wave Harmonics Verification Setup
Set the Calibrator Mainframe to SCOPE mode, with the Levsine menu on the display.
Then follow these steps to verify the leveled sine wave harmonics.
1. Using the BNC cable and BNC(f) to Type N(m) adapter, connect the SCOPE
connector on the Calibrator Mainframe to the HP 8590A.
2. Program the Calibrator Mainframe to 5.5 V p-p at each frequency listed in Table 6-
31. Press O on the Calibrator Mainframe to activate the output.
3. Set HP 8590A start frequency to the Calibrator Mainframe output frequency. Set HP
8590A stop frequency to 10 times the Calibrator Mainframe output frequency. Set the
HP 8590A reference level at +19 dBm.
4. Record the harmonic level reading for each frequency and harmonic listed in Table 6-
31. For harmonics 3, 4, and 5, record the highest harmonic level of the three
measured. Harmonics should be below the levels listed in the tolerance column of
Table 6-31.
