Option 1E1 Output Attenuator Behavior and Use

When using the internal detector, the Option 1E1 output attenuator enables signal generator power
levels down to −130 dBm at the RF Output connector. It accomplishes this by adding attenuation to
the output signal after the ALC detection circuit. The output power value (shown in the Amplitude
area of the display) is the resultant of the Set Atten and Set ALC Level values (see page 110). With
the external detector selected, the output attenuator no longer attenuates the output signal since the
