Real-time control interface (R&S

SMW-K503/-K504 options)

The R&S

SMW-K503/-K504 option enhances the R&S

SMW-B9 wideband baseband generator option by adding a dedicated 1 Gbit/s

LAN interface for pulse descriptor word (PDW) streaming. PDWs are streamed via the external LAN interface to control a real-time

sequencer on the R&S

SMW-B9. Either a precalculated waveform can be played back or certain signals such as rectangular pulses,

Barker codes and chirps can be generated in real time.

In addition to these different signal types, the interface provides agile switching of frequency, phase and amplitude. These variations

are calculated in real time.

The real-time control interface is controlled by an external simulator that streams the PDWs in a proprietary Rohde & Schwarz format.

At least one R&S

SMW-B9 wideband baseband generator option and one R&S

SMW-K502 option must be installed. If two

R&S

SMW-B9 options and two R&S

SMW-K502 options are installed (signal paths A and B), the real-time control interface can be

used either on signal path A or B with R&S

SMW-K503 or -K504 option. For simultaneous usage on signal paths A and B, two

R&S

SMW-K503/-K504 options must be installed. The R&S

SMW-K504 option increases the maximum PDW rate from 1 MPDW to

2 MPDW. Each R&S

SMW-K504 option requires an R&S

SMW-K503 option to be installed.

Pulse-on-pulse simulation (R&S

SMW-K315 option)

This option enhances the R&S

SMW-K502 option to simulate up to 6 true parallel instances of the extended sequencer in a single

instrument. It allows the generation of time overlapping pulse-on-pulse signals. As a result, up to 6 emitters can be generated

simultaneously in one R&S

SMW200A. If the R&S

SMW-K306 option is installed, each extended sequencer can also be used to

generate a group of interleaved emitters. In case of interleaving emitters, drop-out rates can be reduced by distributing emitters onto

more hardware resources.

Two R&S

SMW-B9 options (wideband baseband generator), two R&S

SMW-K502 options and at least two R&S

SMW200A Vector Signal Generator

Agile sequencing (R&S

SMW-K506 option)

Agile sequencing allows external control and fast arbitrary switching of prestored ARB segments by streaming of ARB descriptor

words (ADW) including a waveform ID to the R&S

SMW200A. The R&S

SMW-K506 option enhances the R&S

SMW-B9 wideband

baseband generator option by adding ADW streaming via a dedicated, low latency 10 Gbit/s LAN interface over an existing QSFP+

interface.

In addition to ARB segment sequencing, the interface provides agile switching of frequency, phase and amplitude. These variations

are applied in real time.

At least one R&S

SMW-B9 wideband baseband generator option must be installed. If two R&S

SMW-B9 options are installed (signal

paths A and B), the agile sequencing can be used either on signal path A or B with one R&S

SMW-K506 option. For simultaneous

usage on signal paths A and B, two R&S

SMW-K506 options must be installed.
