2.2 About Bandwidth Extension

Equipped with option R&S SMW-K555, the R&S SMW allows you to extend band-

widths of I/Q modulated signals.

Principle

A practical approach is to superimpose RF signals with center frequencies close to

each other. The bandwidths of the modulated baseband signal overlap. The figure Fig-

ure 2-1 illustrates the superposition of two adjacent baseband signals band A (band-

width fBW A, center frequency fc A) and band B (bandwidth fBW B, center frequency fc B).

fc A = Center frequency band A

fc B = Center frequency band B

fc= Center frequency of band A and band B

fOL = Bandwidth overlap between band A and band B

Ideally, the resulting baseband signal has an extended bandwidth fBW = fBW A + fBW B at

center frequency fc. In reality, destructive interference effects occur at the bandwidth

overlap fOL and result in a signal level drop at fc. To compensate the signal level drop,

phase corrections are added so that signal level of the resulting band A+B is constant

over the whole bandwidth range fBW.

About phase corrections

You can obtain phase correction data, for example, from a coupled alignment source

after combining the baseband signals. The alignment source can be a power sensor or

R&S SMW or multiple R&S SMW instruments for generation of extended bandwidth

signals. It covers the following topics:

3.1 Test setups

This chapter provides an overview on test setups for bandwidth extension. Test setups

can include one or more R&S SMW vector signal generators. In this description, all test

setups also include a power combiner and a directional coupler.

For alignment of the RF output signal of R&S SMW, you can either use a power sensor

or a vector signal analyzer.

Signal generator

One R&S SMW vector signal generator equipped with relevant options, see Chap-

ter 2.1, "Required options", on page 10.

Instruments equipped with frequency options below R&S SMW-B1020/B2020 have an

electronic reference circuit with limited alignment functionality. For full alignment func-

tionality, we recommend that you install options R&S SMW-B1020/B2020 or higher,

see Table 3-1.

Power combiner

To combine RF signals of your test setup, you have to install a power combiner. For

correct operation, use a power combiner that supports the frequency range of your RF

Test setups

R&S®SMW-K555

14User Manual 1179.5776.02 ─ 03

output signal. For example, use the combiner kit R&S SMW-ZKK, if your test setup

generates RF signals with a maximum frequency of 40 GHz.

Directional coupler

To automate alignment of your test setup, you can use a directional coupler. For cor-

rect operation, use a directional coupler with an output coupling factor that is not higher

than 10 dB. For higher coupling factors, the coupling loss is too large to align power

levels.

Power sensor

To align the power levels for synchronization of the RF output signal ("Align RF Ports"),

use a diode sensor. Using thermal sensors can cause erroneous alignment. For exam-

ple, use a diode sensor of the R&S NRP family. You find the diode sensors on the

product page at:

www.rohde-schwarz.com/product/nrp_s_sn

Signal analyzer

To align the local oscillator (LO) phase for synchronization of the RF output signal

("Align Setup"), use a vector signal analyzer. For correct operation, make sure that this

analyzer supports an analysis bandwidth that fits your RF output signal. For example,

use an R&S FSW equipped with option R&S FSW-B4001 for analysis of up to 4 GHz

bandwidth signals. The minimum required equipment is R&S FSW-B2001 for analysis

of up to 2 GHz bandwidth signals. You find the signal analyzer on the product page at:

www.rohde-schwarz.com/product/fsw

3.2 Connecting the R&S SMW

3.2.1 Connecting a single R&S SMW

This chapter provides step-by-step instructions for connecting the R&S SMW with com-

ponents and instruments of a bandwidth extension setup. Connecting procedures for

relevant connector types are summarized. Connecting to these connector types is

analogous for all instruments. The step-by-step instructions cover the following topics:

●"To connect a power combiner" on page 17

●"To connect a directional coupler" on page 19

●"To connect an R&S NRP power sensor" on page 19

●"To connect a signal analyzer" on page 20

To connect a power combiner

The following step-by-step instruction describes how to connect R&S SMW to a power

combiner. Also, it describes how to connect the power combiner and a directional cou-

pler. The R&S SMW is switched on and connected to power.

For prerequisites of the power combiner, see "Power combiner" on page 13.

1. Use high-quality RF cables.

See "Cable selection and electromagnetic interference (EMI)" in the R&S SMW

Getting Started.

2. Use short RF cables of equal length for connection between R&S SMW and power

combiner.

3. For correct operation, use one of the following combiner kits:

● R&S SMW-ZKK for RF output signals of up to 44 GHz

● R&S SMW-ZKV for RF output signals of up to 67 GHz

4. Establish the RF connections.

Step (d) and following steps of this step-by-step instruction assume a connection to

an R&S SMW-ZKV combiner kit. Connecting other power combiners is analogous.

a) Ensure that the RF connector of the R&S SMW is compatible with the RF con-

nectors of the power combiner and the directional coupler.

b) Inspect the RF connectors carefully. Look for metal particles, contaminants and

defects.

If you notice damages at the RF connector, do not proceed, because the risk of

damaging the mating connector is too high.

c) Connect the RF cables.

See chapter "Connecting to RF" in the R&S SMW Getting Started.

d) First, start connecting the cable ends with the power combiner.

e) Connect both the cable ends with the RF output connectors of the R&S SMW.

The figure below shows a power combiner connected to both RF connectors of

a single R&S SMW.

f) Connect the power combiner with the directional coupler.

The tables Table 3-2 and Table 3-3 provide an overview of relevant connections.

To connect a directional coupler

Use a directional coupler to automate alignment.

For prerequisites of the directional coupler, see "Directional coupler" on page 14.

► Establish the RF connections to the directional coupler as described in the other

step-by-step instructions:

● Direction from the power combiner: "To connect a power combiner" on page 17

● Direction to the measurement device:

– Sensor: "To connect an R&S NRP power sensor" on page 19

– Analyzer: "To connect a signal analyzer" on page 22

The tables Table 3-4 and Table 3-5 provide an overview of relevant connections.

To connect an R&S NRP power sensor

The following step-by-step instruction describes how to connect R&S SMW to an

R&S NRP power sensor as alignment source. Also, it describes how to connect the

power sensor and a directional coupler. The R&S SMW is switched on and connected

to power.

For prerequisites of the power sensor, see "Power sensor" on page 14.

1. Use all cables delivered with the R&S NRP power sensor. Other connections can

require additional cables.

a) For the control connection, use the cable R&S NRP-ZK6 as delivered with the

R&S NRP power sensor.

b) For the RF connection, use a high-quality cable.

See "Cable selection and electromagnetic interference (EMI)" in the R&S SMW

getting started.

2. Insert the host connector of the power sensor into the "SENSOR" of the

R&S SMW.

3. Establish the RF connection between power sensor and directional coupler.

a) Ensure that the RF connector of the directional coupler is compatible with the

RF connector of the power sensor.

b) Inspect both RF connectors carefully. Look for metal particles, contaminants

and defects.

If you notice damages at either RF connector, do not proceed, because the risk

of damaging the mating connector is too high.

c) Insert the RF connector of the power sensor straight into the RF output of the

To connect a signal analyzer

The following step-by-step instruction describes how to connect R&S SMW and a

directional coupler to an Rohde & Schwarz signal analyzer as alignment source. The

R&S SMW and signal analyzer are switched on and connected to power.

For prerequisites of the signal analyzer, see "Signal analyzer" on page 14.

1. Connect "RF Input 50Ω" connector of the signal analyzer to the RF output of the

directional coupler.

2. Establish a LAN connection between R&S SMW and signal analyzer.

3.2.2 Connecting multiple R&S SMW instruments

This chapter provides step-by-step instructions for connecting the R&S SMW with com-

ponents and instruments of a bandwidth extension setup. Connecting procedures for

relevant connector types are summarized. Connecting to these connector types is

analogous for all instruments. The step-by-step instructions cover the following topics:
