Measuring Insertion Phase Response
7. To view both the magnitude and phase response of the device, as shown in Figure 2-31,
press:
The channel 2 portion of Figure 2-31 shows the insertion phase response of the device under
test. The analyzer measures and displays phase over the range of
-
MO0
to +
1800.
As phase
changes beyond these values, a sharp
360°
transition occurs in the displayed data.
