Test 2-1: Closed Channel Resistance Test

This test verifies that all relay contacts meet the closed-channel resistance
specification for the multiplexer. If the closed-channel resistance of any
relay contact is greater than 2

Ω

, the relay should be replaced. This test uses

the test fixture (see Figure 2-1).

Measuring Protection

Resistors

Since there are 100

Ω

protection resistors (R20 through R31) in the relay

paths, measure the protection resistor values to begin this test. The values of
the protection resistors are then subtracted from the measured path
resistance to determine the relay contact resistance. To measure the
protection resistor values, set the 3458A DMM to 4-wire ohms, autorange
and measure each resistor value with the DMM (see Figure 2-2). Record the
measured values in Table 2-1.

NOTE

On the E1343A and E1344A, Resistors R22, R25, R28, and R31 are 1.0k

Ω

resistors.
