H. 5 Channel Mode
1. From pilots mode, press F3 to select 5 Channel mode. The
5 CHAN label will appear in the upper right corner of the screen.
2. The instrument displays the signal levels for the five preset
frequencies in bar graphs and in numeric readouts. The preset
frequencies are displayed under the preset labels across the
bottom of the screen. The vertical screen resolution is displayed
in the upper right portion of the screen.
3. The REF LVL value in the upper left corner of the screen
represents the level at the top of the measurement screen, and is
set automatically by the instrument. The offset below it
represents the probe loss value.
You can change the probe loss value and the high and low pilot
frequencies through the Measure Setup Menu, which is accessed
with the following key sequence: UTIL – CONFIG – MEAS SET-
UP. After making changes, press ESC as necessary to return to
the pilots mode.
I. All Channel Mode
1. Press LEVEL, then press F4 to enter the ALL CHAN mode. The
ALL CHAN label will appear in the upper right corner of the
screen.
2. The instrument displays all channels in the active channel table,
in the form of a vertical line graph. The vertical screen resolution
is displayed in the upper right portion of the screen.
You can change the active channel table, as described in Step C
on page 1–6.
3. You can set the REF LVL (in the upper left corner of the screen)
by pressing F1, then turning the knob. Since the reference level
represents the value at the top of the measurement screen,
changing it will effectively move the graph vertically with
respect to the screen.
