Modulation Monitor
Full-featured Modulation Monitoring
The DaySequerra M2.0 HD RadioTM modulation monitor has been designed to meet the
demands of the professional broadcast market and deliver the highest quality, accurate
monitoring of HD Radio
built-in preselector and double-balanced mixer provides benchmark sensitivity of 5.0dBf for FM
broadcasts. The M2’s over-sampling DAC and Class-A biased audio outputs provide the
highest fidelity demodulation of HD Radio
>90dB), including display of program specific data (PSD) for MPS and SPS Multicast signals.

The M2.0 is the first “Tomorrow Radio Ready” modulation monitor available with built-in
Multicast demodulation capability, and its robust, modular architecture ensures that the M2.0 will
never become obsolete. The rugged M2.0 chassis houses dedicated RF, audio, CPU and power
supply modules that along with firmware updates via flash programmable memory, completely
anticipate future HD Radio
product update program ensures that a broadcaster’s investment in a DaySequerra product will
continue to pay off well into the future.

High Resolution Displays
The high-resolution 58-segment multi-color LED carrier modulation meter can display positive
peaks only, negative peaks only, or both simultaneously from 46% to 125% with a 5% resolution
full range and a 1% resolution between 80% and 105%. Measurement integration time is user
programmable at 0.1mSec, 0.2 mSec, 0.5 mSec or 1.0 mSec.
The demodulated audio multi-color LED meter displays Left and Right or L+R and L–R
demodulated program audio. The display is peak responding between +10dB and – 30dB, and
average responding between –30dB and –64dB.

Upgrade Path
The M2.0’s unique architecture, modular design and on-board flash based microprocessors
permit a clear upgrade path without losing any value of a broadcast station’s original hardware
investment.
Option M2.1 adds FM analog signal monitoring capabilities to the M2.0 including peak-type
measurements of the injection level for 19kHz pilot, 38kHz, 57kHz, 67kHz and 92 kHz subcarriers, and front panel indications for synchronous AM noise. A rear panel MPX Output for
external sub-carrier decoding is also included.
Option M2.2 includes M2.2 Remote Dashboard
application, and a network interface that permits remote control and monitoring of the M2.0 for
both AM and FM HD Radio
