Maximize Operator
Eficiency
Time in the ield is extremely valuable and
always limited. The N6829BS Snapshot
Radio software enables an operator or
ield technician to focus on survey and
data collection while on station knowing
they can easily replay recordings after the
fact. The N6829BS can demodulate IQ
recordings made by either the N6820ES
Signal Surveyor 4D or 89601B Vector
Signal Analyzer software. It is also able
to play a variety of audio format iles
produced by other receiver assets.
Once the signal data is recorded to a ile,
reviewers can work at their own pace
without risk of losing valuable time or
data. Recordings can be edited, iltered
and reined for sharing or reporting
purposes.
Recordings can be demodulated by the
N6829BS software and evaluated for
voice or data content. For data recordings,
demodulated audio can be input to
commercial decoding software for
identiication purposes as outlined in
ITU-R recommendation SM.1600,
“Technical Identiication of Digital Signals.”
Full-featured Playback
The N6829BS software shows the signal
ile playback in the time domain, a tuner
function showing the full bandwidth of
the ile, and a processing function for
enhancing the conversion to voice.
Besides the typical playback functions,
the N6829BS software lets the user select
regions of time and repeat or loop on
those regions. You can tune the frequency
of SSB signals with the mouse in real-time
while listening. The bandwidth of the
processing function is user-selectable.
The N6829BS processing functions can
display either the modulated or demodu-
lated signal, in the frequency or time
domain. Modulation of AM, FM, USB,
LSB, and CW detections is automatically
chosen but it is also user-selectable. You
can choose a low-pass ilter function to
remove CTCSS tones or choose the voice
enhance ilter to remove noise.
Multiple reviewers using the N6829BS ile player can
be organized in a hierarchy for maximum eficiency.
To simplify sharing the ile with others
who do not have N6829BS software, the
selected portion of the returned signal
can be saved as a .wav or .16t ile, with all
demodulation and iltering already applied.
Dramatically Compress
Playback Review
The N6829BS software has a squelch
function that skips over portions of the
recorded data that does not contain voice.
By removing the noise and “dead time” in
a recording, reviewers can quickly listen
to two-sided voice transmissions, thereby
dramatically compressing the playback
time. Reviewers might only need to hear a
few seconds of this compressed two-sided
voice transmission to determine if the
recording should be saved or deleted.
Squelch function skips over the noise in playback to signiicantly compress listening time and reduce fatigue.
