HP 181A 2.7 to 3.0 GHz Sensitivity for Option 030 only

		Chapter 1 Performance Tests
		Test 5: Option 030/050/124 Channel 3 Frequency Sensitivity (HP
		53131A/132A Only)
	3	Increase the power level in 5 dB steps until the Counter displays a
		stable reading of approximately 2.5 GHz.
1		The Counter should display 2.5 GHz at ≤ −27.0 dBm (10 mVrms).
	4	Sweep the frequencies from 2.5 GHz to 200 MHz.
		The Counter should read frequencies from 2.5 GHz to 200 MHz at
		≤ −27.0 dBm (10 mVrms).
5		Record the actual reading in the Performance Test Record
		(Test 5, Line 1).
		2.7 to 3.0 GHz Sensitivity for Option 030 only
1		Disconnect the HP 8663A Synthesized Signal Generator from the
		Counter (see Figure 1-9), and connect the HP 8340B Sweep
		Oscillator to Channel 3 of the Counter.
2		Change the settings of the Sweep Oscillator to 3.0 GHz, −40 dBm.
3		Increase the power level in 1 dB steps until the Counter displays a
		stable reading of approximately 3.0 GHz.
		The Counter should display 3.0 GHz at ≤ −21.0 dBm.
4		Sweep the frequencies from 3.0 GHz to 2.7 GHz.
		The Counter should read frequencies from 3.0 to 2.7 GHz at ≤ −21.0 dBm.
5		Record the actual reading in the Performance Test Record
		(Test 5, Line 2).
6		Disconnect the test setup.
