Hardkey and Softkey Reference ESG Family Signal Generators
LF Out
4-52 User’s Guide
Dual-Sine
Pressing this softkey reveals a menu of choices for setting the dual-sine
low frequency output parameters. In this menu you can set the
frequencies for two separate tones. In addition you can set a ratio of the
tone 2 LF amplitude to the tone 1 LF amplitude.
Softkey Location:
LF Out > LF Out Source > Function Generator >
LF Out Waveform > Dual-Sine
Ext
This softkey is one of the choices in the LF Output Sweep Trigger
menu. Choosing
Ext allows you to trigger swept-sine low frequency
output using the signal applied to the TRIGGER IN rear panel
connector. Set the polarity of the trigger signal using the
Trigger In Polarity Neg Pos softkey.

Function Generator
This softkey lets you set the LF Out Source to be a function generator. You
can select a frequency and shape in addition to selecting the amplitude
for a signal that is output at the LF OUTPUT front panel connector.
When you use the internal source in this capacity, any modulation with
the internal source selected is turned off.
Softkey Location:
LF Out > LF Out Source > Function Generator
Immediate
This softkey is one of the choices in the LF Output Sweep Trigger
menu. Choosing
Immediate immediately triggers swept-sine low
frequency output in a continuous mode. To stop the sw eep, choose a
different trigger such as
Ext, or set th e waveform to some thin g othe r
than
Swept-Sine.
