R&S®AFQ100A I/Q Modulation Generator
Meeting new challenges in baseband signal generation
Broad scope of applications
- Variable memory clock rate (1 kHz to 300 MHz) can be optimally adjusted to the useful signal
- Maximum I/Q bandwidth of up to 100 MHz for an RF bandwidth of 200 MHz
- Long signal duration – 256 Msample or 1 Gsample
- Analog I/Q outputs (balanced and unbalanced) and optional digital outputs
- Variable output level at the analog outputs
- Multisegment waveform reduces switching time between different signals; no reloading required
- Optimum memory use due to integrated clock rate converter and memory granularity of 1
- Shiftable markers without disrupting and recalculating the output signal
Outstanding signal quality
- Excellent spurious free dynamic range (SFDR) of typ. 83 dBc (1 MHz signal at 100 MHz bandwidth)
- Frequency response typ. 0.05 dB across 100 MHz I/Q bandwidth
- Versatile impairments
- Settable skew with 10 ps resolution to allow exact adjustment of different cable lengths
- Gain and offset for I and Q can be set independently
- Phase error
- Loadable equalization to compensate for external components such as I/Q modulators (minimum frequency response in realtime across all components involved)
Connectors and operation
- Adjustment of DC offsets by biasing the differential I/Q outputs
- Remote control via GPIB, USB and LAN
- User interface via external monitor or Windows XP Remote Desktop
- R&S® WinIQSIM2™ for controlling the R&S® AFQ100A and generating test signals in line with different standards
- Direct control via MATLAB®
- USB connectors for USB equipment (keyboard, mouse, memory stick)
