Agilent Technologies 6683A Primary Interface SA Test, Valid A2U106 ROM Firmware Revision A.01.06

Table 3-5. Primary Interface SA Test

Description: These signatures check some primary interface circuits on the Systems Supply A2 GPIB Board.

Valid A2U106 ROM Firmware Revision: A.01.06

Test Setup: See Figure 3-17.

1.Turn off the power supply and remove the top cover.

2.Connect SA jumper of connector J106 on A2 GPIB Board (see Figure 3-15).

3.Connect signature analyzer CLOCK, START, STOP, and GROUND inputs as show in Figure 3-16 .

4.Turn on the power supply and use the signature analyzer probe to take the following signatures:

Power:	5V = 9FFP
Serial Link:	A2U109-3 = 0104
Microprocessor: A2U114-24 = 9FFP
	A2U114-25 = UF39
Digital Control Interface: A2U118-1 = 9AF1
	A2U118-9 = 40A5
	A2U118-10 = 1029
	A2U118-15	= 0010
	A2U118-16 = 040A
Gated Array Logic: A2U119-2 = 0A55
	A2U119-5	= 0040
	A2U119-15	= 0040

5.After completing the tests, be sure to return the J106 jumper to its original position.
