2.4.3. Test Procedure
The following paragraphs describe the general operational test procedures
PeakTech
®
1100.
Please
verify with test equipments that have proper specification.
2.4.3.1. Frequency
1)
Set Modulation=OFF, Power Level = -13 dBm, Frequency = 50 MHz.
2)
Then measure the output frequency
3)
and change the frequency to 150 MHz and repeat.
4)
Use the rotary knob to change the frequency to 70 MHz and repeat the measurement.
5)
Use the key pad to enter 50 MHz and change the frequency to 40 MHz using the rotary knob,
while verifying for the correct frequencies.
2.4.3.2. Output Level
1)
Set Modulation = OFF, Frequency = 400 kHz, and Level = 100 dB
µ
.
2)
Measure the output level using a power meter.
3)
Then change the frequency to 50 MHz and the level to 96 dB
µ
4)
Verify the level. Set the frequency to 150 MHz and the level to 92 dB
µ
and check the level.
5)
Change the level to 84 dB
µ
and do the same.
2.4.3.3. AM
1)
Set Frequency = 50 MHz and Level = -3 dBm. Select INT AM, 1kHz
2)
Using modulation analyzer, verify AM at AM = 60%.
3)
Change the output frequency to 100 MHz and repeat.
4)
Change the internal source frequency to 400 Hz(INT 400 Hz) and verify the same.
2.4.3.4. FM
1)
Set Level = 100 dB
µ
, Frequency = 50 MHz, INT FM (1 kHz).
2)
Set FM deviation to 100 kHz and verify the deviation value with modulation analyzer.
3)
Change the output frequency to 150 MHz and select internal 400 Hz(INT 400 Hz) source.
4)
Verify the deviation value.
2.4.3.5. EXTERNAL AM/FM
1)
Using the front panel External Modulation connector,
2)
Apply the external modulation source to test EXT AM and EXT FM.
3)
Repeat (2.4.3.3) and (2.4.3.4).
