4-12. TUNING ACCURACY (Cont'd)

NOTE

The 10 dB attenuator should be connected directly to the INPUT 50Qof the spectrum analyzer and the 11667Apower splitter (no cable assembly should be used between attenuator and analyzer or power splitter).

8.Adjust sweep oscillator for CW output at 3.000 GHz, as measured by frequency counter. Vary POWER LEVEL control as required for accurate measurement. Adjust spectrum analyzer TUNING control to center signal on display. FREQUENCY GHz readout should indicate:

Min. Actual Max.

9.Using procedure of step 8, check spectrum analyzer tuning accuracy at remaining frequencies listed in Table 4-3.Indication on FREQUENCY GHz readout must fall within corresponding test limits at each frequency.

NOTE

Use SIG IDENT to verify that spectrum analyzer is tuned to desired in-band signal response whenever tuning error appears excessive.
