Couplings If you reduce the attenuation, the instrument may have to lower the reference level to keep it below
its allowed maximum. This allowed maximum level is specified in the “Max” row, below, along with
other variables that affect it.
When you increase attenuation, the reference level does not change.
Preset 106.99 dBuV
State Saved Saved in instrument state.
Min RefLevelMin = –63.01dBuV + RefLevelOffset - ExtGain.
Max RefLevelMax = 206.99 dBuV + RefLevelOffset – External Gain
Default Unit Depends on the current selected Y axis unit
Initial S/W Revision A.07.00
Attenuation
Enables you to set the value of the Attenuation parameter. This key only affects the Mechanical Attenuator
in the EMI Receiver mode and has no Auto setting.
For the Frequency Scan measurement, this key only affects the attenuation used for meters.
The following amplitude parameters are not settableby the user and therefore do not appear in any
menus:
Elec Attenuator Disabled
Elec Attenuation 0dB
Meas Atten Step 2dB
Max Mixer Level –10dBm
EMI Receiver Mode Reference 381
