Example:
rs_exam.ftf
in the directory
D:\UPV\User
In addition to this file format, an equalization file (example:
rs_exam.veq
in the direc-
tory
D:\UPV\User
) can be loaded as a shape file. The amplitudes of individual fre-
quency lines are set regarding to the equalization frequency response. The noise sig-
nal band is limited to the frequency range defined in the equalization file.
Remote command:
MMEMory:LOAD:...
Muting
"Muting" gives the option of switching off the generator when the measurement is com-
pleted and the generator signal is no longer needed.
"Off" The generator signal always remains switched on, independently of
the measurement. This setting is necessary if the generator is in
operation without the analyzer, or if the DUT requires a long settling
time.
"After Meas" The generator signal is switched off when the (single) measurement
is completed. When a continuous measurement is in progress, the
generator signal also remains on continuously.
This setting is necessary if the measurement function or the DUT
requires a low level before the start of measurement, e.g. with the
R&S
UPP measurement function "Delay".
When the measurement is started, the generator signal is automati-
cally switched on. Since no signal is present before the measurement
is started, a potential delay of the DUT must be considered as "Start
Cond Delay".

Spacing
Used to set the frequency grid. The frequency of each sine-wave line is an integer mul-
tiple of this frequency grid.
"Def" The frequency grid can be freely defined.
Minimum value: Sampling rate/16384
If frequency grid has been defined in the file, the parameter field
where a value would be entered for this setting is grayed out and the
value is displayed instead.
