Hardkey and Softkey Reference
LF Out
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.
Softkey Location: Press
LF Out, LF Out Off On
Status after Normal Preset: Off
SCPI Commands:
[:SOURce]:LFOutput:STATe ON|OFF|1|0
[:SOURce]:LFOutput:STATe?
LF Out Period
Use this softkey to change 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
µs 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.
