Documented Performance - In a class by itself

An industry first: A high-performing precision video demodulator that is the equal of those costing three times as much. And we include performance documentation generated on a VM 700 with each msi 320 that leaves the factory.

One look at the performance data provides proof positive that the msi 320 equals any professional demodulator and is heads above any video demodulator in its price range.

Compare the Modulation Sciences msi 320 to video demodulators costing up to three times as much. Compare its features to precision demodulators on the market today. Then compare its price.

It's easy to see why the msi 320 creates a whole new category of professional demodulators. And why it stands alone in performance versus cost.

How do we do it?
We start with an original design by Modulation Sciences that maximizes the use of the most advanced components and takes advantage of their performance and economy. Definitely not a repackaged consumer or cable receiver, the msi 320 is the first precision demodulator to come along in two decades that tops the industry in performance. And it's the first video/aural demodulator ever to combine both high performance and an affordable price into one, easy-to-use package.

Maximizes modern components
Modulation Sciences uses state-of-the-art integrated circuits that deliver performance, which used to be available only with complicated circuit boards packed with discrete components. Not only do today's advanced ICs cost a fraction of what the old discrete circuits did, but they are streamlined for performance, without the time-consuming--and often unstable--tweaks and fine-tuning that used to drive up manufacturing and calibration costs.

The result is a trouble-free, precision demodulator maximized for performance with superb specifications and elegantly engineered professional features.

User-Friendly Menus - Easy to Read
The front panel of the msi 320 is free of clutter and complicated controls. It has a single, legible fluorescent display--not an LCD--so it can be set up and read even in low light conditions. One dual-function, concentric control, a single headphone jack, and a two-line menu display--that's everything needed to set up and perform a wide range of precision video measurements.

Full Text Menus
The two-line, 40-character display (20 characters per line) communicates in full text. Each of the selection items, such as the clamping of video to either sync or back porch, and zero carrier reference line selection are full text menu items on the display. The display itself employs a pleasing and highly legible fluorescent emissive technology, as opposed to harder-to-read LCD displays. Another plus is that the built in status alarms are also full text.

Multi Language
The NTSC version of the msi 320 is front panel selectable between English, French and Spanish.

Reliable and Versatile Operations
The msi 320 is fully RF shielded and designed for use in the studio and at the transmitter site. It's selectable menu offers the widest possible range of precise measurements. And, its RS-232 capability provides control and status monitoring from remote locations.

Single, Dual-Function Concentric Knob
A large, skirted dual-function, concentric knob is the only front panel control on the msi 320. The outer, skirted knob selects the function in the window, and the inner knob chooses the parameters of the function. For example, the outer knob would choose the Channel Select display and the inner knob would be used to set the actual Channel. It's quick and easy-to-use.

Professional Features--Plus!
Modulation Sciences designed the msi 320 to take full advantage of precision components while keeping the entire package in the affordable price range; there has been no compromising when it comes to professional features. Like all of Modulation Sciences products, the msi 320 has been engineered for top performance and includes many features only found on much costlier equipment--and then some.

Frequency Agile
The msi 320 provides tuning to over-the-air, U.S. television channels 2-69 plus cable channels.

Continuous Tuning
Continuous, all-channel tuning--with front-panel selection of any channel--is easily accessible, yet can be locked to a single channel to prevent unauthorized channel surfing. Locking avoid errors or accidents in channel selection.

Impressive Performance
The quality built into the msi 320 is evident. Just take one look at these examples of it's impressively good numbers: < 1.20 Differential phase; < 1.2% Differential gain. Correct chroma/luminance delay (170 ns) to 30 ns.

Zero Carrier Reference
The selectable line zero carrier reference feature sets two-thirds of one line of the video signal to zero modulation, enabling easy setup for waveform measurements.

Nyquist SAW Filter
Custom, ovenized SAW filter provides an accurate low frequency video response, correct chroma/luminance delay, and a nearly ideal sound trap.

Professional Features--Plus!

Sound Trap
Every msi 320 demodulator shipped includes a sound trap and full chroma/luminance delay compensation. This is the preferred mode for day-to-day monitoring and testing.

Additional Outputs for ICPM
In addition to its two video outputs, the msi 320 has separate, quadrature outputs which allow measuring of Incidental Carrier Phase Modulation (ICPM).

Synchronous Video Detector
Maximum linearity for accurate modulation depth measurement.

Sync Tip or Back Porch Clamping
Choose either from the menu and optimize the signal display for the type of measurements most suitable to your own applications.

Advanced Engineering---Including Precision AuralWe've integrated Modulation Sciences years of experience in fine audio, modulation and processing--including MTS--into the design and performance of the msi 320. The result is a video demodulator with impressive aural specs and flexible extras.

High Quality Wideband Aural
The msi 320 provides wideband composite baseband aural demodulation for MTS stereo decoding with the top of the line audio signal you expect from a leader in TV stereo.

Choice Of Aural Detectors
Split (Non-Intercarrier) Aural
Non-intercarrier detection ensures accurate aural measurements independent of ICPM--Incidental Carrier Phase Modulation. Not only is this method far more accurate for aural measurements, but it allows for measurements in the absence of a visual carrier.

Quasi Parallel Aural
To get a better overall idea of the aural signal, especially to determine more closely how it operates during reception, the Quasi Parallel mode provides additional flexibility.

Transformer Balanced Audio
Eliminates hum and RF noise and allows easy integration of the msi 320 into your current system.

RS 232 Remote Control
Control and monitor the msi 320 locally or from remote locations via modem.

Traceable Calibration
Through the use of the most modern video test equipment, traceable calibration documentation is available as an option.
