2.5.4 Internal Level Control - Bandwidth Selection
BANDWIDTH
Selection of the bandwidth of the level control.
AUTO The bandwidth is automatically adapted to the operating conditions.
IEC-bus command SOUR:POW:ALC:BAND:AUTO ON
100 kHz Bandwidth narrow. This setting improves AM noise with carrier offset
>100 kHz. However, the AM bandwidth is restricted..
IEC-bus command SOUR
:POW:ALC:BAND 100kHz;BAND:AUTO OFF
500 kHz Full bandwidth

2.5.5 User Correction (UCOR)
Function "User Correction" can be used to create and activate lists in which arbitrary RF frequencies are
assigned level correction values.
Up to 10 lists with a total of 160 correction values can be compiled. For frequencies which are not
included in the list the level correction is determined by means of interpolation of the nearest correction
values.
When user correction is switched on, the LEVEL indication is completed by the indication UCOR (User
Correction) in the header field of the display. The RF output level is the sum of both values.
LEVEL + UCOR = output level
If the offset setting is used at the same time, the LEVEL indication value is the difference of the input
values AMPLITUDE and OFFSET of the menu LEVEL.
AMPLITUDE
−
OFFSET = LEVEL
The user correction is effective in all operating modes if switched on.
