Explanation
When "Int" modulation source is selected, the AM modulation depth (
a
m
) and
amplitude difference (
sb
ΔP
) between the carrier and sidebands satisfy the
following relation:
asb
mΔP lg206 =
.
<value> can also be expressed as percentage. For example, 80%.
After the modulation depth is set, you can rotate the knob to modify the
modulation depth at the current step. You can set and query the current step
using the [:SOURce]:AM[:DEPTh]:STEP[:INCRement] command.
Return Format The query returns the modulation depth. For example, 80.00.
Example
:AM:DEPT 80
:AM:DEPT?

Explanation <value> can also be expressed as percentage. For example, 0.2%.
After the modulation depth step is set, you can rotate the knob to modify the
modulation depth at the current step. At this point, you can query or set the
modulation depth using the [:SOURce]:AM[:DEPTh] command.
Return Format The query returns the modulation depth step. For example, 0.20.
Example
AM:DEPT:STEP:INCR 0.2
