LF Out Off On
This softkey toggles on and off the output of the selected source at the
LF OUTPUT front panel connector. You can choose either the
modulation signal generated by the internal source or you can use the
low frequency source as a function generator and select that signal to
output at the LF OUTPUT connector. Refer to the description of the
LF Out Source softkey in this section for more information on choosing the
source.
Once you have toggled this state on, the signal is immediately available
at the LF OUTPUT connector. The
Mod On/Off and RF On/Off keys do not
apply to this state.
Default Value: Off
Softkey Location:
LF Out > LF Out Off On
LF Out Period
Changes the pulse period for the pulsed low frequency waveform. To
change the period, press the softkey once. The current value for pulse
period is displayed in the active entry area. To enter a new value, rotate
the front panel knob until the desired value is displayed, use the up and
down arrow keys, or enter the value using the numeric keypad and
press the
µsec or msec terminator softkey. The range of values allowed is
from 16
µ
s to 30 s. If you set the pulse period to a smaller value than the
pulse width, an error message will be generated and the pulse width
will be reduced to the value of the pulse period.
This softkey is only active when you have selected the internal source to
operate as a function generator and when the LF Out waveform is
specified as pulse.
