To test the logic analyzer probe cables

To test the logic analyzer probe cables

This test allows you to functionally verify the probe cable and probe tip assembly of any of the logic analyzer pods. Only one probe cable can be tested at a time. Repeat this test for each probe cable to be tested.

Equipment Required

Equipment	Critical Specification	Recommended
		Model/Part
Pulse Generator	100 MHz, 3.5 ns pulse width,	Agilent 8131A Option 020
	< 600 ps rise time
Adapter (Qty 4)	SMA (m) - BNC (f)	Agilent 1250-1200
Coupler (Qty 4)	BNC (m)(m)	Agilent 1250-0216
6x2 Test Connectors (Qty 4)

1Turn on the equipment required. Insert the operating system disk and turn on the logic analyzer.

2Set up the pulse generator.

a Set up the pulse generator according to the following table.

Pulse Generator Setup

Channel 1	Channel 2	Period
Delay: 0 ps	Delay: 0 ps	100 ns
Dty: 50%	Dty: 50%
High: 3.00 V	High: 3.00 V
Low: 0.00 V	Low: 0.00 V

bEnable the pulse generator channel 1 and channel 2 outputs (with the LEDs off).

3 Set up the logic analyzer Configuration menu.

aPress the Config key.

bIn the Analyzer 1 box, select the field to the right of Type, then select State.
