Selecting the measurement mode
The 9102 provides different measurement modes:
– The spectrum analysis mode is most versatile. It provides most of
the options included in all other modes. For more information on
this mode, refer to page 55.
– The channel power mode allows you to measure the radiated
power within a certain frequency band. Read more about the
channel power mode on page 81.
– The transmission mode, which is available in the (VSWR/)Tracking
... submenu accessible from the Mode menu, allows you to deter-
mine the frequency characteristics of active and passive devices.
Read more about this mode on page 115.
– The signal generator mode, which is also available in the (VSWR/
)Tracking ... submenu, can be used to generate a signal for stimu-
lating an electronic circuit. Read more about this mode on
page 109.
If the 9130 VSWR/DTF Reflection Measurement Option is installed and
activated on your 9102, three additional modes are available in the
VSWR/Tracking ... submenu. If the option is not installed, this submenu
has the menu name Tracking ... and the additional modes are not avail-
able. For details on the 9130 VSWR/DTF Reflection Measurement
Option please refer to Chapter 8: “The 9130 VSWR/DTF Reflection
Measurement Option”. For details on checking installed options and
installing new ones refer to “Checking installed options” on page 43
and “Installing a new option” on page 44.
All three modes can be selected in the VSWR/Tracking ... submenu
accessible from the Mode menu:
– The reflection mode provides high-precision measurements of the
reflection of antenna systems via vector measurements on the
reflected wave. Read more about this mode on page 143.
– The distance to fault mode offers a detailed analysis of antenna
feeder cables in order to identify causes for faults like weak
connectors, cable kinks etc. Read more about this mode on
page 163.
– The cable loss mode allows you to determine the average cable
loss. Read more about this mode on page 173.
