Setting the Scale
Auto Scale
The Site Master can automatically set the scales to the minimum and maximum values of
the measurement on the y-axis of the display. This function is particularly useful for mea-
surements in SWR mode. To automatically set the scales:
Step 1.
Press the AUTO SCALE key.
The Site Master will automatically set the top and bottom scales to the minimum
and maximum values of the measurement on the y-axis of the display.
Amplitude Scale
The following procedure sets the top and bottom scale display.
Step 2.
Press the AMPLITUDE key to call up the Scale Menu.
Step 3. Press the
TOP soft key and use the keypad or Up/Down arrow key to edit the top
scale value.
Step 4. Press the BOTTOM soft key and use the keypad or Up/Down arrow key to edit
the bottom scale value.
NOTE: Typically the y-axis scale of the display is 0-54 dB (return loss) but for
some measurements (for example, insertion loss) the scale should be changed
to 0-10 dB. If the scale is not changed, some measurement results may not be
easily displayed on the screen.
Set the Distance and Cable Type
In Distance-To-Fault (DTF) mode, the length of the transmission line (distance) and cable
type are selected. The cable type determines the velocity propagation and cable attenuation
factor. The following procedure can be used to set the distance and select the appropriate
cable type.
NOTE: Selecting the correct cable is very important for accurate measurements
and for identifying faults in the transmission line. Selecting the incorrect cable
type will shift the DTF trace vertically and horizontally making it difficult to accu-
rately locate faults.
Step 1.
Press the MODE key.
Step 2. Select
DTF RETURN LOSS or DTF SWR mode. The Site Master automatically
sets D1 to zero.
Step 3. Press the
D2 soft key.
Step 4. Enter the appropriate D2 value for the maximum length of the transmission line
and press the ENTER key to set the D2 value.
Step 5. Press the
DTF AID soft key.
