Setting The Electrical Delay; Setting The Cw Frequency - Agilent Technologies 8719D User Manual

Setting the Electrical
This feature adds phase delay to a variation in phase versus frequency, therefore it is only
applicable for ratioed inputs.
2. Press (MarkerFctn) and turn the front panel knob, or enter a value from the front panel
keypad to position the marker at a point of interest.
input to compensate for the phase slope at the active marker position. This effectively
flattens the phase trace around the active marker. You can use this to measure the electrical
length or deviation from linear phase.
Additional electrical delay adjustments are required on devices without constant group delay
over the measured frequency span.
