Anrtisu Cell Master MT8212B, User Manual, Page: 35 / 294

ues for Relative Propagation Velocity and Nominal Attenuation in dB/m or
dB/ft @ 1000 MHz, 2000 MHz and 2500 MHz.) The custom cable folder
can consist of up to 49 user-defined cable parameters uploaded via the
Handheld Software Tools program.
q
Window
— Opens a menu of FFT windowing types for the DTF calcula-
tion. Scroll the menu using the Up/Down arrow key and make a selection
with the ENTER key. Refer to Appendix B for more details on window-
ing.
q
Back
— Returns to the Distance Menu.
AMPLITUDE Choosing the AMPLITUDE key in cable and antenna analyzer measurement
modes causes the soft keys, below, to be displayed and the corresponding values
to be shown in the message area or scale menu depending on the measurement
mode.
q
Top
— Opens the top parameter for data entry and provides for setting the
top scale value. Press ENTER when data entry is complete.
q
Bottom
— Opens the bottom parameter for data entry and provides for setting
the bottom scale value. Press ENTER when data entry is complete.
MEAS/DISP Choosing MEAS/DISP in cable and antenna analyzer freq or DTF measurement
modes causes the soft keys below to be displayed.
q
Resolution
— Opens the status window to change the resolution. Choose 130,
259, or 517 data points. (In DTF mode, resolution can only be adjusted
through the DTF Aid table.)
q
Single Sweep
— Toggles the sweep between single sweep and continuous
sweep. In single sweep mode, each sweep must be activated by the
RUN/HOLD button.
q
Trace Math
— Opens up the Trace Math functions (trace-memory or
trace+memory) for comparison of the real time trace in the status window
with any of the traces from memory. (Not available in DTF mode.)
q
Trace Overlay
— Opens up the Trace Overlay functions menu to allow the
current trace to be displayed with a trace in memory overlaid on it. Choose
On
or
Off
and
Select Trace
to select the trace from memory to be overlaid.
q
Fixed CW
— Toggles the fixed CW function ON or OFF. When OFF, a nar-
row band of frequencies around the selected frequency is generated. This en-
hances the immunity of the Cell Master to an interfering signal. When CW is
ON, only a single frequency with a very narrow band width is generated by
the Cell Master. The sweep speed is somewhat faster in CW ON mode. If
CW is ON during normal RL or SWR measurements, it will be more suscep-
tible to interfering signals, so use this feature with caution. Interfering signals
can make the measurement look better or worse than it really is.
