Coupling (AC/DC)
Selects the coupling mode (AC or DC) for the external signal.
"AC"
Disconnects the DC voltage component and uses only the AC com-
ponent of the modulation signal.
"DC"
Uses the modulation signal with both components, AC and DC.
For active external exponential AM, sets the coupling of the corre-
sponding input automatically to DC.
Remote command:
[:SOURce<hw>]:INPut:MODext:COUPling<ch> on page 651
Impedance
Sets the impedance for the externally supplied signal.
Remote command:
[:SOURce<hw>]:INPut:MODext:IMPedance<ch> on page 651
Bandwidth
Displays the maximum bandwidth of the external LF signal.
Remote command:
[:SOURce]:LFOutput<ch>:BANDwidth? on page 654
Show Connector
Accesses a dialog that displays the physical location of the selected connector on the
front/rear panel of the instrument.
