AM Sweep Trigger
Supported PSG-A Series
Use this softkey to access a menu of choices that enables you to select the triggering
mode for the swept-sine amplitude modulation.
AM Tone 1 Rate
Supported PSG-A Series
This softkey enables you to set the internal modulation frequency for the AM tone 1 of
the dual-sine AM waveform.
Preset 400.0 Hz
Range 0.5 Hz
−
1.0 MHz (minimum increment allowed is 0.5 Hz)
Location Page 231
Remarks This softkey is coupled to the
AM Rate softkey in the AM menu and the
AM Start Rate softkey in the AM Dual-Sine menu. Any value set for
AM Tone 1 Rate is reflected in the AM Rate and AM Start Rate softkeys.
AM Tone 2 Ampl Percent Of Peak
Supported PSG-A Series
This softkey enables you to adjust the amplitude of the alternate frequency as a
percentage of the total amplitude. For example, if the tone 2 amplitude is set to 30% of
the total amplitude, then the primary frequency is 70% of the total amplitude.
Preset 50.0%
Range 0.1%−99.9%

Remarks You can also configure the polarity of the TTL signal output at the
TRIGGER OUT connector using the
Trigger Out Polarity Neg Pos softkey
on this menu. Refer to “Trigger Out Polarity Neg Pos” on page 222.
