AF Generator DC Level Accuracy

Performance Test 9

The purpose of this test is to verify that the Test Set meets the

specification limits in PTR (Performance Test Record) Table 9-9, “AF

Generator DC Level Accuracy Test 9 Record,” on page 258. There are

two DC generators. DC level accuracy is measured directly with a

digital multi meter.

Figure 8-14 Setup

Procedure

1. Set the multimeter to measure DC volts.

2. On the Test Set:

a. Press

Preset.

b. Select the RF GENERATOR screen.

c. Set the AFGen1 To and AFGen2 To fields to Audio Out.

d. Set the AFGen1 Freq and AFGen2 Freq fields to 0.0 Hz.

e. Set the Audio Out field to DC.

3. On the Test Set for Audio Frequency Generator 1 do the following:

a. Set the AFGen2 To level field to Off.

b. Set the audio frequency and level as shown in the Performance

Test Record (PTR) and measure the DC level. Compare the

measured voltage to the limits.

4. On the Test Set for Audio Frequency Generator 2 do the following:

a. Set the AFGen1 To level field to Off and AFGen2 To level field to

on.

b. Set the audio frequency and level as shown in the PTR and

measure the DC level. Compare the measured voltage to the

limits.
