2-4 Transmission Measurements
Option 20 includes normalized transmission measurements. This functionality is similar to a
previous option, Option 21 “2-Port Transmission Measurement”.
1. Connect a through cable between
GENERATOR/RF OUT
and
ANALYZER/RF In
connectors. From the
Generator
submenu, press the
Transmission Measurement
submenu key and then set
Normalize On.
2. Figure 2-6 shows a through cable measurement after normalization. Note the relative
scale numbers on the graticule lines (in increments of 10 dB) on the right side of the
sweep window now that Normalization is
ON
. If desired, the resolution bandwidth and
video bandwidth can be changed after normalization without needing to renormalize.
After the normalization sweep is completed, reconnect the DUT between the
GENERATOR/RF OUT
and
ANALYZER/RF In
connectors.
Figure 2-7 shows the filter measurement after normalization. Displaying the trace
required changing the
Relative Ref
(top of the graticule) and the
Relative Scale
(db range between grids).
Refer to
“Transmission Measurement Menu” on page 2-13 for additional information
including
Transmission Statistics
and
Transmission Offset
.

Note
Set the appropriate input attenuation needed before turning Normalization ON.
The Amplitude menus and the Frequency menus are disabled while
Normalization is ON.
