r&s®afq100a i/q modulation generator | features & benefits -55体育
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)
