Preamp
Switches the preamplifier on or off.
For details on the preamplifier, see "Preamplifier" on page 313.
Remote command:
[SENSe:]ESPectrum<sb>:RANGe<ri>:INPut:GAIN:STATe on page 668
Transducer Factor
Sets a transducer for the specified range. You can only choose a transducer that fulfills
the following conditions:
●
The transducer overlaps or equals the span of the range.
●
The x-axis is linear.
●
The unit is dB.
For details on transducers, see Chapter 9.7.1, "Basics on Transducer Factors",
on page 523.
Remote command:
[SENSe:]ESPectrum<sb>:RANGe<ri>:TRANsducer on page 676
Limit Check <n>
Sets the type of limit check for the n-th power class in the range. Up to four limits are
possible.
For details on limit checks, see "Limit Lines in SEM Measurements" on page 166.
The limit state affects the availability of all limit settings.
Remote command:
[SENSe:]ESPectrum<sb>:RANGe<ri>:LIMit<li>:STATe on page 673
CALCulate<n>:LIMit<li>:FAIL? on page 914
Abs Limit Start / Stop <n>
Sets an absolute limit value for the n-th power class at the start or stop frequency of
the range [dBm].
Remote command:
[SENSe:]ESPectrum<sb>:RANGe<ri>:LIMit<li>:ABSolute:STARt
on page 668
[SENSe:]ESPectrum<sb>:RANGe<ri>:LIMit<li>:ABSolute:STOP
on page 669
Rel Limit Start / Stop <n>
Sets a relative limit value for the n-th power class at the start or stop frequency of the
range [dBc].
By default, this value is a fixed relative limit, i.e. no function is defined. To define a
function for the relative limit, select the input field for "Rel Limit Start" or "Rel Limit
Stop" and then the "f(x)" icon that appears.
