Variable Sweep; Mhz Step Measurement - Berkeley Varitronics Systems Fox Manual

When in the text screen, the strongest 7 frequencies are displayed with the strongest on the top of the display, weakest on the
bottom.
HIGHEST dBm LATCH
The highest dBm reading for each frequency is held or "latched". If the unit is left on for a period of time in one location, this
feature will show all of the highest readings for this time period. Use this feature when trying to determine frequency traffic
at the location of the measurement. To turn "latching" on and off, press the
the SURVEY measurements, pressing the
being displayed.

1 MHZ STEP MEASUREMENT

This measurement sweeps the entire band from
start to end frequency at a fixed 1 MHz step.
All frequencies are displayed along the X axis,
with the start frequency at the origin (left side
of graph), and increasing by the step frequency
towards the right side of the graph. The frequency
marked by the dotted line cursor is displayed digi-
tally below the X axis. Use the
LEFT ARROW keys to move the cursor position and change the frequency displayed numerically.
BEST/SCAN key will move the dotted line cursor to the strongest frequency currently

VARIABLE SWEEP

Use this measurement to display a selected portion
of the frequency band. Enter the start frequency
of the sweep, the end is automatically calculated
based on the frequency step. The frequency step
can be adjusted during the measurement using the
UP and DOWN ARROW keys. The current sweep
start, end and frequency steps are displayed on the
right side of the screen.
Note: The last step selected in the VAR SWEEP menu
is used in determining the ADJ CHAN measurement.
(see ADJACENT CHANNEL in this manual.)
