Using an Internal Modulation Source

Using an Internal Modulation Source

1. Preset the signal generator.
2. Set the carrier (RF) frequency.
3. Set the RF amplitude.
4. Configure the modulation:
AM
a. Press AM
b. Set the AM type (Linear or Exponential):
to highlight desired type.
AM Type
c. Set the AM Mode (Normal or Deep).
Default is Deep. To select Normal enable
More to highlight desired type.
d. Set the AM Depth:
Default 0.01%
Range 0.01 to 100%
e. Set the rate:
More > Setup AM Source > AM Rate > value
> frequency unit
5. Turn on the modulation:
AM
AM Off On softkey to On
The appropriate modulation annunciator displays, indicating that you enabled modulation.
6. Turn on the RF output.
The RF output LED lights, indicating that the signal is transmitting from the RF output connector.
If the modulation does not seem to be working properly, refer to
on page 382.
