The MSD200C and PT0200C, Master
Stereo Meter, from DK-Technologies
offer PPM/VU level meter, audio vector
oscilloscope and phase meter as the
primary tools.
Phase Meter
The phase meter is of the “center-zero”
type and immediately advises out-ofphase errors by pointing towards the [-1]
area and changing to red colour.
The Level Meter has direct selection of 7
PPM/VU scales. All the standard scales
are available including Nordic, EBU,
BBC, ABC, NBC, DIN, VU, Digital and
others. Each scale can be configured
individually concerning overload level
and reference level. Furthermore the
colour and width of each PPM bar can be
set by the user.
The DK-SCALETM software program for
Windows contains a large library of
scales, which can easily be downloaded
to the meter. Modification of existing
scales or designing of new scales according to your own specifications are
also possible with the software. For easy
identification each channel can be
named individually with up to 4 characters.
Signal Generator
Another strong point of the instruments is
the built-in signal generator. It has a tone
generator variable in frequency from 31
Hz to 20000 Hz, and the level in steps of
0,1 dB.
In addition it can generate the EBU test
signal, pulse signals, and white and pink
noise signals for use with the spectrum
analysers. Use the generator to turn the
instruments into a powerful measurement
tool for analysis of linearity and distortion.
Stereo Sound
The oscilloscope shows the stereo image
in the Lissajous-format, where a perfect
stereo signal would be represented by a
circular figure, or a ‘ball’, and mono
would be a vertical line.
• Bright, VGA colour display with
The FFT spectrum of the input signal is calculated at 1024 discrete frequencies.

• VGA output connects directly to

larger screen.

the right has selectable scales.

Spectrum Analyser
The spectrum analyser section has both
an FFT-analyser and a 1/3 octave analyser.
The FFT is primarily used for accurate
measurements and exact identification of
problem frequencies. To this end a cursor is available and level and frequency
will be shown for each cursor position
across the frequency range on the display.

What is a Goniometer
The goniometer or „audio vector oscilloscope“ is an instrument that can give a
detailed picture of the relationships in a
stereo signal - or between two arbitrary
signals. The idea behind the instrument
was developed by Holger Lauridsen, the
Chief Engineer at Denmarks Radio in the
1940s and early 1950s.
It involves an oscilloscope with one input
being used for the X-deflection and the
other input for the Y-deflection. In relation
to a normal oscilloscope, the image is
rotated by 45°.
This means that, when the same signal is
applied in the left and right channels (X
and Y) respectively it leads to a vertical
deflection (a vertical line). If the signals

phase,
thenof athe

will occur in the
horizontal plane (horizontal line).
When the signals are different, the display changes from straight lines to spatial
figures. What is ingenious about the
instrument is that it can show many different parameters in the stereo signal
simultaneously.
A/D & D/A Converters
The analogue inputs have high quality A/
D converters, and the digital inputs have
sample rate converters to ensure the
ability to handle asynchronous signals.
The analogue outputs are equipped with
D/A converters. The instruments can be
used as separate A/D and D/A converters even while you are using the metering functions on the same or other signals.
Other functions
In the digital mode the instruments will
show a Bitstream Status Display.
Other features are the timecode input
which will synchronize to SMPTE, and a
Statistical Session Report showing highest true peak, number of “overs”, and
“unders” over time.
Audio Matrix
The instruments contain a complete 4 x 4
audio matrix. It can route, in broadcast
program quality, any input to any output.
The x-points of the source and destination channels can be easily selected from
Compact Construction
The instruments are very compact units.
Everything has been fitted into a box not
much bigger than the size of a pocketbook. The MSD200C will fit nicely onto
your console or work desk, and the
PT0200C may be conveniently installed
next to a video waveform monitor. The
PT0200C-BNC is a special version of the
PT0200C equipped with BNC connectors
for easy connection to 75 Ohm digital
audio lines.
On the rear of the instrument a single DSub connector provides access to the
inputs and outputs.
The utility input connector holds the
power connection, the RS232 communication port, and a sync input. A separate
connector provides the output to an external VGA-monitor.
Rack Mounting
The 1/3-octave analyser has 30 bars,
grouped in full octaves from 20 Hz to
16000 Hz. This standard tool is primarily
used during recording to check the energy distribution of the signal.
The 1/3-Octave spectrum shows the energy
distribution of the input signal
the menu. The DK-MATRIXTM software
makes the selection of x-points and several other parameters even easier. Specific instrument set-ups may be stored in
any of the 11 presets for later recall.
The PT0200C fits into the standard rack
mount cabinet next to a video waveform
monitor such as the PT5664 Digital and
Analogue Waveform Monitor. The combi-
nation offers simultaneous monitoring
and test of the audio and video signals in
television environments.
