Remote command:
[SENSe:]ESPectrum<sb>:RANGe<ri>:INPut:ATTenuation
on page 925
Preamp
Switches the preamplifier on or off.
For details on the preamplifier, see "Preamplifier" on page 455.
Remote command:
[SENSe:]ESPectrum<sb>:RANGe<ri>:INPut:GAIN:STATe
on page 926
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 12.3.1, "Basics on Transducer Factors" ,
on page 675.
Remote command:
[SENSe:]ESPectrum<sb>:RANGe<ri>:TRANsducer
on page 935
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 Chapter 7.6.4.2, "Limit Lines in SEM Measurements" ,
on page 242.
The limit state affects the availability of all limit settings.
Remote command:
[SENSe:]ESPectrum<sb>:RANGe<ri>:LIMit<li>:STATe
on page 932
CALCulate<n>:LIMit<li>:FAIL?
on page 1224
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 927
[SENSe:]ESPectrum<sb>:RANGe<ri>:LIMit<li>:ABSolute:STOP
on page 928
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.
