background image

Mon Freq

Display of the actual monitored frequency.

Dev

Display of the frequency deviation in kHz.

Freq Err

The acquisition frequency error range is +1500
Hz as described for the RF Display.

Input Lvl

(Recall that Input Lvl is a short term average
not affected by the value selected for Slots.)

Errs

Display of the bit error count detected during
the test.

Bits

Display of the bit count during the test.

BER

Display of the ratio of bit errors to total bits
counted during the test. BER is displayed as a
percentage. The BER for one error in one
thousand bits is

00.1000%.

NOTE

BER Meter measurement is accurate up to

20 percent bit errors.

Enabling the BER Test

The BER test begins when BER meter is selected
in the Display Zone "Meter:" field.

Resetting the BER Test

To reset the BER test, move cursor to the
"Meter:" field in the Display Zone and press
more until reset is displayed. Press reset and the
BER count is started over from zero.

13-10.2 CLEAR SCOPE Display

The CLEAR SCOPE display shows either the
received audio signal after it has been converted
to analog or the analog transmit signal before it is
digitized. To activate the CLEAR SCOPE, place
the analyzer in SECURENET mode. The
selection of either Monitor or Generate in the RF
Zone determines which signal will be displayed
on the screen. Press the DISP hardkey, place the
cursor in "Display:" field, and select the CLEAR
SCOPE softkey. The Display area of the screen
will indicate CLEAR SCOPE with the input sig-
nal displayed in a time-versus-amplitude graph.
figure 13-16 shows the display, cursor and
associated softkey used for the CLEAR SCOPE.

The operator can adjust the horizontal scale by
placing the cursor in "Horiz:" field and selecting
the appropriate value from the softkey selections.

To change the vertical scale, go to the "Vert:"
field and select the appropriate value from the
softkey selections.

13-10.2.1 Monitor Mode

In Monitor mode, the CLEAR SCOPE display
shows the recovered analog audio signal. The
CLEAR SCOPE operational controls are similar
to the Standard version MOD SCOPE except the
vertical scope is mv/div instead of kHz/div.

To change horizontal position, horizontal range,
vertical position, or vertical range, use the cursor
control keys to highlight the appropriate cursor
fields as follows:

Horiz

Press the desired softkey to select the Horizon-
tal Sweep rate (20



s to 1 sec/div).

Since all ranges cannot be shown on one
screen, press the

more

softkey for additional

selections.
