Parameters

Unit (default)

[SOURce]:AM:DEPTh

<value>

0.8 (80 PCT)

[SOURce]:AM:STATe

ON|OFF|1|0

[SOURce]:AM:INTernal:FREQuency

<value>

400 Hz

[SOURce]:AM:SOURce

:AM:DEPTh

[SOURce]:AM[:DEPTh]: <value>

[SOURce]:AM[:DEPTh]:?

This command sets the amplitude modulation depth 0...1.

*RST 0.8

Range 0-0.99

:AM:INT:FREQuency

[SOURce]:AM:INTernal:FREQuency <value><unit>|UP|DOWN

[SOURce]:AM:INTernal:FREQuency?

This command sets the internal amplitude modulation rate.

*RST 400 Hz

Range 10 Hz to 50’000 Hz

The RF carrier is modulated when you have set the signal generator’s AM modulation state to ON.

Whenever amplitude modulation is enabled, the AM on is in the display.
