Attenuation
Auto Man
Allows you to select between automatic and manual adjustment of the
tracking generator’s output attenuator. The Agilent E4401B and
Agilent E4411B can be manually adjusted from 0 to 60 dB in 10 dB
steps. All other Agilent ESA analyzers can be manually adjusted from 0
to 56 dB in 8 dB steps. When auto-coupled, the attenuation function
automatically adjusts the attenuator to yield the source amplitude level
specified by the
Amplitude On Off softkey function. For the Agilent
E4401B and E4411B, press
Attenuation (Man) for power sweeps greater
than 10 dB.
Amptd Step
Auto Man
Allows the user to set the step size of the power level range of the
tracking generator. The default setting is one vertical scale division.
Amptd Offset Offsets the displayed power of the tracking generator. Using the
amplitude offset capability of the tracking generator allows you to take
system losses or gains into account, thereby displaying the actual
power delivered to the device under test.
Tracking Peak Agilent E4402B, E4403B, E4404B, E4405B, E4407B, and E4408B only.
Activates a routine that automatically adjusts fine tracking
adjustments to obtain the peak response of the tracking generator on
the spectrum analyzer display. Tracking Peak is performed in the active
resolution bandwidth.
Man Track Adj Agilent E4402B, E4403B, E4404B, E4405B, E4407B, and E4408B only.
Allows you to adjust the frequency of the tracking generator oscillator
manually using the step keys, knob, or numeric keypad. The tracking
adjust is tuned to maximize the amplitude of the trace.
NOTE When Source is On, resolution bandwidths less than 1 kHz are not
available.
NOTE When the resolution bandwidth is less than 1 kHz, Source may not be
turned on.
