FREQ CNTR
CAUTION
This softkey provides a general purpose fre-
quency counter (figure 3-15) for Audio and IF
frequency measurements up to 500 kHz. For RF
frequency measurements, use the MON function.
Do not input frequencies above 400 kHz to the
period counter. Slow down of system
operations will result.
DPL Decode
The "Resolution:" field provides selection of auto
ranging or selectable gate times which provides
up to 0.1 Hz resolution (0.1 Hz resolution
requires 20 sec gate time). The symbol to the
right of the display is an indication of when
gating occurs.
This softkey provides decoding for valid
Motorola Digital Private-Line (DPL) codes.
Refer to Appendix B for applicable codes.
Selection of high and low pass filters may be
made from this screen as previously described.
NOTE
DTMF Decode
Selection of any of the General Sequence, 5/6
or Select V decoding functions produces an
overwrite display table. To exit this display
an alternate selection must be made from the
"Meter:" field of the Display zone.
This softkey provides a means of decoding
DTMF (Dual Tone Multi Freq) signaling for
testing telephone interfaced systems. A "reset"
softkey clears the display.
