Performance Verification

Functional Test

To functionally test the GB1400, connect the Generator to the Analyzer and confirm their correct operation as described below.

Note

In these procedures, the Generator and Analyzer are returned to their default settings. The word memories will be reset. If you have entered word patterns that you do not want to lose, use a GPIB or RS-232C controller to save them before beginning these procedures.

qStep 1: Make connections appropriate to the options installed as follows:

Connections for Functional Test

Option	From	To	Comment
Standard Instrument	TX Clock	RX Clock	50 Ohm, SMA coax
	TX Not Clock	RX Not Clock	50 Ohm, SMA coax
	TX Data	RX Data	50 Ohm, SMA coax
	TX Not Data	RX Not Data	50 Ohm, SMA coax
75 Ohm Option	TX Clock	RX Clock	50 Ohm, SMA coax.
	TX Not Clock	RX Not Clock	Use SMA to BNC
	TX Data	RX Data	adapters and 75 Ohm
			BNC coaxial cables
	TX Not Data	RX Not Data

See Figure 1 for Setup of Functional Test.

qStep 2: Reset both the Generator and Analyzer to their factory default settings. Press the ‘CLEAR’ key in the PATTERN section, the ‘MSB(1)’ key and the ‘VIEW ANGLE’ key, and hold down all three keys while cycling the power.

The message DEFAULT SETTINGS should appear briefly on the display of each unit, followed by the GB1400 logo, before the functional display appears.

qStep 3: At the Generator, verify that error injection is off (you should see ERR OFF on the display). If error injection is on, press the ‘SINGLE’ key in the ERROR INJECT section to turn it off.
