Ampl
Supported All
This softkey enables you to set the signal generator to sweep amplitude data only. The
frequency is set at a constant value determined by the
Frequency hardkey.
Preset N/A
Range N/A
Location Page 245
Remarks You can define a sweep containing both amplitude and frequency
information and still choose to sweep only amplitude.
Ampl Offset
Supported All
This softkey enables you to change the value for amplitude offset. An amplitude offset
changes the value shown in the amplitude area of the display but does not affect the
output power. For example, if the current output power is 0.0 dBm and you enter an
amplitude offset of
−
3.0 dBm, the output power will remain at 0.0 dBm but the display
will show an amplitude of
−
3.0 dBm. This feature lets you simulate the power level at a
test point beyond the RF OUTPUT connector.
An amplitude offset can be entered at any time during normal operation and also when
you are operating in amplitude reference mode.
Preset 0.00 dB
Range
−
200 dB to 200 dB
Location Page 232
Remarks Changes to this value affect the displayed amplitude value only, the
actual RF output power amplitude is not changed.
