Trapezoid Rise / Fall ← LF Generator
Sets the time required for the trapezoid signal to change from low level to high level,
and vice versa.
See Modulation Signal Waveforms.
Remote command:
[:SOURce<hw>]:LFOutput<ch>:SHAPe:TRAPeze:RISE on page 1069
[:SOURce<hw>]:LFOutput<ch>:SHAPe:TRAPeze:FALL on page 1068
Trapezoid High ← LF Generator
Sets how long the trapezoid signal is at high level.
Remote command:
[:SOURce<hw>]:LFOutput<ch>:SHAPe:TRAPeze:HIGH on page 1069
External
The "External" settings section contains all parameters required to configure the signal
of an externally supplied LF signal.
Coupling (AC/DC) ← External
Selects the coupling mode (AC or DC) for the external signal.
Note: You can set the coupling of the external modulation signal for AM, FM and ΦM
separately.
Remote command:
[:SOURce<hw>]:INPut:MODext:COUPling<ch> on page 1047
Impedance ← External
Sets the impedance for the externally supplied signal.
Remote command:
[:SOURce<hw>]:INPut:MODext:IMPedance<ch> on page 1048
Bandwidth ← External
Displays the bandwidth of the external LF signal.
Remote command:
[:SOURce]:LFOutput<ch>:BANDwidth? on page 1063
Show Connector ← External
Accesses a dialog that displays the physical location of the selected connector on the
front/rear panel of the instrument.
A blinking LED on the front/rear panel indicates the selected connector, too (see "Con-
nector status indication" on page 663).
Noise Generator
The "Noise Generator" settings contain all parameters to configure the signal of the
internal noise generator.
Distribution ← Noise Generator
Selects the distribution of the noise power density.
"Gaussian"
Generates the noise power according to a Gaussian distribution.
