Rohde & Schwarz R&S

SMW200A Vector Signal Generator 69

Bandwidth extension (R&S

SMW-K555 option)

The R&S

SMW-K555 option requires two R&S

SMW-B9 wideband baseband generator options and two R&S

SMW-K527 baseband

extension to 2 GHz RF bandwidth options. Single and dual unit operation is supported.

Bandwidth extension enhances the usable clock rate of the arbitrary waveform generator up to 4.8 GHz and can be used with any

waveform loaded int the arbitrary waveform generator. To run this option, an external power combiner and a measurement device is

needed. The measurement device can be either an analyzer or a power meter.

Linearize RF (R&S

SMW-K575 option)

The R&S

SMW-K575 option requires at least one R&S

SMW-B10 standard baseband generator or R&S

SMW-B9 wideband

baseband generator.

Linearize RF improves the EVM and ACLR performance for high output powers over the whole RF frequency range of the device.

Notched signals (R&S

SMW-K811 option)

At least one R&S

SMW-B10 standard baseband generator option or R&S

SMW-B9 wideband baseband generator option must be

installed. If two baseband generators are installed, notched signals can be generated either on path A or B with one R&S

SMW-K811

option. For notched signals to be generated on paths A and B simultaneously, two R&S

SMW-K811 must be installed.

Up to 25 band-stop filters can be applied to the baseband signal.

Center frequency and bandwidth can be set independently for each band-stop filter.

Customized digital input (R&S

SMW-K556 option)

With the R&S

SMW-K556 option, I/Q data from an existing hardware can be fed into the BBIN HS DIG I/Q inputs. This option can be

installed once or twice. Each R&S

SMW-K556 option to be installed requires a R&S

SMW-B9 wideband baseband generator option.

The existing hardware requires a Xilinx Virtex FPGA and the corresponding Rohde & Schwarz IP core.
