6-7. Power Supply Checks

voltages listed in Table 6-2 and verifying that

each voltage is within the specified tolerance.

Proper operation of the power supply is as-

Refer to figure 6-1 for the location of voltage

sured by measuring the various power supply

test points.

Table 6-2. Power SUpply Voltage Measurements*

* These measurements are referenced to digital ground (

). All other

voltages are referenced to analog ground (

NOTE

When making measurements with a

voltmeter or oscilloscope, keep in

mind that there are two separate

ground references; analog and dig-

ital ground. The A1 assemblies

referenced to analog ground

and the A2 assembly is referenced

to chassis and digital ground (
