Comprehensive Modulation Support...

MODULAR incorporates a wide range of modulation schemes support including:

BPSK, QPSK, O-QPSK, pi/4-DQPSK
8PSK, O-8PSK (EDGE)
QAM-16/32/64/128/256/512/1024
8-VSB, 16-VSB
2-FSK, 4-FSK, 8-FSK, 16-FSK, 32-FSK, (G)MSK
Sinusoidal Analog: AM, FM, PM

Channel coding and channelization are important features for 2G, 2.5G and 3G mobile telephony, wireless LAN and digital TV testing. MODULAR offers channel-coded signals for the following environments:

DVB-C: QAM-64, QAM-256. Scrambling, interleaving, Reed-Solomon and differential coding supported.
CDMA IS95 (CDMAOne) Downlink: Spreading, channelization, complex scrambling supported.
WCDMA IMT2000 (UMTS) Downlink: Spreading factor, complex scrambling, channelization (OVSF codes), CCPCH-SCH multiplexing, HSDPA support.
IEEE-802.11b: DSS spreading, Barker sequences, CCK modulation.

As each carrier is arbitrarily defined, emulation of multiple signal environments, interfering signals, and transients are easily accommodated.

Modulation Scheme Support

General Purpose Modulation

BPSK, QPSK, OQPSK, pi/4-DQPSK, 8PSK, QAM16/32/ 64/128/256/512/1024, N-FSK, GMSK can be directly selected.

2G/3G/3.5G Support

CDMAOne (IS95) and UMTS (3GPP) downlink signals can be fully defined by the user. Compressed mode and HSDPA are supported.

Advanced Modulation Schemes

Bluetooth, 8/16VSB, Zigbee, EDGE, DVB-C, IEEE 802.11b. Sample IQ files to generate WiMedia or DVB-T signals are available.

Multi-Carrier Generation

Users can define up to 512 carriers with its own modulation parameters, both at the IF/RF or baseband (IQ) levels.

Flexible Modulation Parameters

Multiple choices of base-band filters and roll-off factors are available to the users. Analog modulations can be generated as well.
