[:SOURce]:AM[1]|2:EXTernal[1]|2:IMPedance?
Sets the impedance for the external input.
Example
:AM1:EXT1:IMP 600
The example sets the AM path 1, external 1 source impedance to 600 ohms.
*RST +5.00000000E+001
:AM[1]|2:INTernal[1]|2:FREQuency
Supported Option UNT
[:SOURce]:AM[1]|2:INTernal[1]|2:FREQuency <val><units>|UP|DOWN
[:SOURce]:AM[1]|2:INTernal[1]|2:FREQuency?
Sets the internal AM rate using the variable <val><units>. The command, used with the
UP|DOWN parameters, will change the frequency rate by a user-defined step value. Refer
to the “:PULM:INTernal[1]:FREQuency:STEP" on page 309 for setting the value associated
with the UP and DOWN choices.
The command changes:
• the frequency rate of the first tone of a dual–sine waveform
• the start frequency for a swept–sine waveform
• the AM frequency rate for all other waveforms
Refer to “:AM[1]|2:INTernal[1]|2:FUNCtion:SHAPe" on page 277 for the waveform
selection.
Example
:AM1:INT2:FREQ UP
The example increases the modulation rate for AM path 1, AM internal source 2 by the step
value set with the “:AM:INTernal:FREQuency:STEP[:INCRement]" on page 272.
*RST +4.00000000E+002
Range
• Dual-Sine & Sine: 0.5 Hz - 1 MHz
