states are not held in the instrument but reside on the local PC.

a state. This function is also accessible from the Save/Recall drop down menu.
Manage Named States This menu item is found in the Save/Recall drop down menu. It calls a Manage
Named states window from which you can delete and view named states.
Frequency Select the frequency units (MHz or GHz). The center frequency must be updated
when the incoming signal frequency changes as this frequency setting is used
to determine calibration factors. The best measurement accuracy requires the
frequency to be set and not doing so can be a signi
fi cant source of error.
You can also fi nd this item in the Measurement drop down menu.
Meas Units
Select the power units (dBm, dBW, dBkW, dBuV, dBmV, dBV, W, V, dB Relative).
Limits (On/Off)
Set measurement limit speci fi cations with pass or fail (High/Low) indicators
shown on the digital display panel.
From the Display drop down menu, you can establish a single test limit or upper
and lower test limits. Limits are
fi xed values against which a measured value
is compared. An evaluation is done during a measurement and is expressed as
pass or fail.
For the single limit, the value can be below, equal to, or above this limit and you
may specify any of these conditions as pass or fail.
