Amptd Step
Key access: [MODE] > {Tracking Generator} > {Amptd
Step}
Allows you to set the step size of the power level
range of the tracking generator. The default setting
is one vertical scale division when in a logarithmic
amplitude scale.
Amptd Offset
Key access: [MODE] > {Tracking Generator} >
{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.
Normalize
Key access: [MODE] > {Tracking Generator} > {Normalize}
• Store Ref (1-> 4)
Copies trace 1 into trace 4. Store Ref(1-> 4) must
bepressed before pressing Normalize(On). If
Normalize(On) is pressed before Store Ref(1-> 4), the
error message:
CAU-CAUTION
Power-level sensitive devices connected to the tracking
generator output may be accidentally damaged. This is
because the actual source amplitude will be greater than
the amplitude indicated on the analyzer, when the power
sweep function is being used. The source amplitude value
is used as the starting amplitude for a power sweep. The
ending amplitude for a power sweep is higher than the
source amplitude value and it may actually be set to val-
ues beyond the specified output levels. Therefore, exercise
caution when connecting a power-level sensitive device to
the tracking generator output.
