Rohde & Schwarz AMIQ04 for Rent, I/Q Modulation Generator

Rohde & Schwarz AMIQ04 I/Q Highlights

The AMIQ04 is a dual channel modulation generator engineered for use as an I/Q source for use with complex communication systems. It is programmed and set with WinIQSIM or can be operated from an SMIQ series signal generator. Each channel of the AMIQ04 can store up to 16,000,000 samples. Sequences of sufficient length can therefore be generated at very high symbol rates. The R&S AMIQ04 also features clock frequencies of up to 100 Msamples/s and and a high amplitude resolution of 14 bit at the analog signal output and up to 16 bit at the digital signal output. Unlike typical dual channel ARB generators, the AMIQ04 has automatic amplitude/offset alignment as well as fine adjustment of the skew, which provides excellent symmetry of the two channels, minimizing the error vector.

• 14-bit resolution
• Excellent ACP
• 100 MHz sample rate
• Fine adjustment of I/Q skew
• 78 dB ACP dynamic range (typical of 3GPP FDD)
• Integrated hard disk and floppy drive
• BER Measurement (w/ option B1)
• 4,000,000/16,000,000 sample memory depth
• Generation of broadband digital communication signals (WCDMA, HiperLAN2, IEEE 802.11a)
• Downloading of calculated waveforms and signals also from integrated floppy disk drive
• Auto-alignment and additional user correction of amplitude and offset
• Wide dynamic range through the use of 14-bit D/A converter, ideal for multicarrier applications
• WinIQSIM software is a Windows program for calculating I and Q baseband signals allows simple generation of complex modulation signals
• Functionality ranges from single-carrier modulation, generation of multicarrier, CDMA and WCDMA signals through to TDMA frame configuration with the help of convenient data editor
• All modulation parameters and impairments can be simulated for single-carrier, multicarrier as well as for CDMA signals
• Complex modulation signals can be generated, such as WCDMA 3GPP, which is similar to QPSK, or 8PSK EDGE modulation with 3?/8 shifting for the EDGE enhancement in the GSM standard
• OFDM for HIPERLAN/2, where a data stream is transferred via a large number of carriers is a special modulation format that can also be generated
