The Cell ID preset displays the Primary Synchronization Signal (PSS) and
the Secondary Synchronization Signal (SSS) in a Constellation diagram. It
also provides Frequency Error.
The ACLR preset measures the E-UTRA and the UTRA adjacent channels,
with different chip rates for UTRA. ACLR also supports Noise Correction
based on the noise measured when there is no input. Both ACLR and SEM
will operate in swept mode (default) or in faster single acquisition (real-time)
when the measurement bandwidth required is less than 40 MHz.
Playback of recorded signals can reduce hours of watching and waiting for
a spectral violation to minutes at your desk reviewing recorded data.
Recording length is limited only by storage media size and recording is a
basic feature included in SignalVu-PC. SignalVu-PC application SV56
Playback allows for complete analysis by all SignalVu-PC measurements,
including DPX Spectrogram. Minimum signal duration specifications are
maintained during playback. AM/FM audio demodulation can be performed.
Variable span, resolution bandwidth, analysis length, and bandwidth are all
available. Frequency mask testing can be performed on recorded signals
up to 40 MHz in span, with actions on mask violation including beep, stop,
save trace, save picture, and save data. Portions of the playback can be
selected and looped for repeat examination of signals of interest. Playback
can be skip-free, or time gaps can be inserted to reduce review time. A Live
Rate playback ensures fidelity of AM/FM demodulation and provides a
1:1 playback vs. actual time. Clock time of the recording is displayed in the
spectrogram markers for correlation to real world events. In the illustration
below, the FM band is being replayed, with a mask applied to detect
spectral violations, simultaneous with listening to the FM signal at the
center frequency of 92.3 MHz.
The signal classification application (SV54) enables expert systems
guidance to aid the user in classifying signals. It provides graphical tools
that allow you to quickly create a spectral region of interest, enabling you to
classify and sort signals efficiently. The spectral profile mask, when overlaid
on top of a trace, provides signal shape guidance, while frequency,
bandwidth, channel number, and location are displayed allowing for quick
checks. WLAN, GSM, W-CDMA, CDMA, Bluetooth standard and enhanced
data rate, LTE FDD and TDD, and ATSC signals can be quickly and simply
classified. Databases can be imported from your H500/RSA2500 signal
database library for easy transition to the new software base.
Above is a typical signal survey. This survey is of a portion of the TV broadcast band,
and 7 regions have been declared as either Permitted, Unknown, or Unauthorized, as
indicated by the color bars for each region.
In this illustration, a single region has been selected. Since we have declared this to be
an ATSC video signal, the spectrum mask for the ATSC signal is shown overlaid in the
region. The signal is a close match to the spectrum mask, including the vestigial carrier
at the lower side of the signal, characteristic of ATSC broadcasts.
SignalVu-PC with mapping can be used to manually indicate the azimuth of
a measurement made in the field, greatly aiding in triangulation efforts. The
addition of a smart antenna able to report its direction to SignalVu-PC
automates this process. Automatically plotting the azimuth/bearing of a
measurement during interference hunting can greatly speed the time spent
searching for the source of interference. Tektronix offers the Alaris DF-
A0047 handheld direction finding antenna with frequency coverage from
20 MHz -8.5 GHz (optional 9 kHz-20 MHz) as part of a complete
interference hunting solution. Azimuth information and the selected
measurement is automatically recorded on the SignalVu-PC Map just by
releasing the control button on the antenna. Full specifications for the DF-
A0047 antenna are available in a separate antenna datasheet available on
