Select
one of the ten possible sequences. Enter the pro-
grammable tone frequency from 0 to 20,000 Hz and the
time duration from 0 to 10,000 milliseconds. Press a
code synthesizer key to select Tone Sequence Mode.
Place the MODULATION switch in burst or continu-
ous position to initiate the sequence. Each of the ten-
tone frequencies will be generated in sequence for its
duration before the generator proceeds to the next tone.

GENERAL SEQ DECODE
• MOBILE TELEPHONE SIGNALING
The Analyzer simulates base to mobile and mobile to
base sequences. It generates the appropriate signaling
sequence, verifies
mobile radiotelephone response, de-
codes
and displays tone frequencies and telephone num-
bers. An error message during a sequence indicates
radio failure. To reset the mobile telephone decoder and
initiate a new sequence, press" I" for "START" again.
FIGURE 3-30. GENERAL DECODE DISPLAY
• GENERAL DECODE
Figure 3-30 shows a display for the general ten-tone se-
quence decode table on page 6. Frequencies and time
durations are derived from the input signal. Frequency
is displayed up to a maximum value of 9999 Hz (I Hz
resolution). No display in a FREQ field with a time
duration in the TIME field indicates that a space oc-
curred between the preceding tone burst and the follow-
ing
tone burst. Time is displayed up to a maximum
value of 9999 milliseconds (I ms resolution).

FIGURE 3-28. SELECT V DECODE DISPLAY
• SELECT V DECODE
Figure 3-28 shows a decode display on page 3. Select one
of the five sequences to display the decoded access code
for Select V. If an invalid frequency is detected within
the sequence, a dash replaces that digit. The display
shows
decoded tone frequencies for each code digit, to a
maximum 10,000 Hz with 1 Hz resolution. The display
shows the time duration that the tone for each digit was
present, to a 1 second maximum with I millisecond
resolution.
