command:
[:SOURce[n]][:CHANnel[m]]:AM[:INTernal]:FREQuency[l]?
syntax:
[:SOURce[n]][:CHANnel[m]]:AM[:INTernal]:FREQuency[l]? [MIN|DEF|MAX]
description:
Returns the frequency of the amplitude modulation as a float value in Hertz.
parameters:
MIN: minimum modulation frequency
MAX: maximum modulation frequency
DEF: This is not the preset (*RST) default value but is half the sum of, the minimum modulation frequency and the maximum
modulation frequency.
Use [l] to query the modulation frequency of the upper or lower wavelength laser source of a dual-wavelength laser source
or a return loss module with an internal dual-wavelength laser source. The default value of [l] is 1, the lower wavelength
source. The upper wavelength source is denoted by 2.
response:
modulation frequency relevant to the current value or specified parameter (if MIN, MAX, or DEF is chosen as a parameter).
example:
sour2:am:freq? min -> +2.00000000E+002<END>
affects:
All laser sources, DFB sources, and tunable laser modules except 81950A.
