3-8SPURIOUS SIGNALS TEST: RF OUTPUT SIGNALS ￿2 GHz (￿2.2 GHz for 68XX5B

MODELS)

The following test can be used to verify that the signal generator meets its spurious signals specifications for RF output signals from

0.01to 2 GHz (0.5 to 2.2 GHz for 682X5B/683X5B Models). This test is applicable only to instruments which cover the frequency range 10 MHz to 2 GHz (500 MHz to 2.2 GHz for 682X5B/683X5B models). The

0.01to 2 GHz test procedure begins on this page; the 0.5 to 2.2 GHz test procedure begins on page 3-17.

Test Setup Connect the equipment, shown in Figure 3-3, as fol- lows:

1. Connect the 682XXB/683XXB rear panel 10 MHz REF OUT to the Spectrum Analyzer External Ref- erence Input.

2. Connect the 682XXB/683XXB RF OUTPUT to the Spectrum Analyzer RF Input.

Procedure	of the 0.01 to 2 GHz RF output to verify that they
	meet specifications.
	1. Set up the Spectrum Analyzer as follows:
	a. Span: 10 MHz/div
	b. CF: 50 MHz
	c. RBW: 1 MHz
	d. Sweep Time/Div: Auto (to resolve signal peaks
	clearly)
