14.16.5 SOURce:INPut subsystem
The SOURce:INPut subsystem contains the commands for configuring the inputs for
external modulation signals. The instrument trigger setting influences all sweeps and is
effective in the List mode (Instrument Trigger).

[:SOURce<hw>]:INPut:MODext:COUPling<ch> <Coupling>
Selects the coupling mode for an externally applied modulation signal.
Parameters:
<Coupling> AC | DC
AC
Passes the AC signal component of the modulation signal.
DC
Passes the modulation signal with both components, AC and
DC.
For active external exponential AM, automatically sets [:
SOURce<hw>]:INPut:MODext:COUPling<ch>DC.
*RST: AC
Example:
INP:MOD:COUP AC
Selects the coupling mode AC for an externally applied modula-
tion signal.
Manual operation: See "Coupling (AC/DC)" on page 118
[:SOURce<hw>]:INPut:MODext:IMPedance<ch> <Impedance>
Sets the impedance for the externally supplied modulation signal.
Parameters:
<Impedance> G50 | G600 | HIGH
G50 = 50 Ohm to ground
G600 = 600 Ohm to ground
HIGH = 100 kOhm to ground
*RST: HIGH
