To construct the test connector

To construct the test connector

The Agilent 54621D/22D Mixed-Signal Oscilloscope has digital channels that you will need to connect to test equipment during testing. To easily connect the digital channels, you will construct a test connector only if the 01660-63801 Test Fixture is not available.

Construct Test Connector only if Test Fixture is not available

The test connector is not required if 01660-63801 Test Fixture is available.

Table 3-1	Materials Required to Construct the Test Connectors

	Description	Recommended Part	Qty
	BNC (f) Connector	Agilent 1250-1032	1
	Berg Strip, 8-by-2		1
	Jumper wire

1Obtain a BNC connector and an 8-by-2 section of Berg strip.

2On one side of the Berg strip, solder a jumper wire to all of the pins.

3On the other side of the Berg strip, solder another jumper wire to all of the pins.

4Solder the center of the BNC connector to a center pin on one of the rows on the Berg strip.

5Solder the ground tab of the BNC connector to a center pin on the other row on the Berg strip.
