6 Trying Out the Instrument

This chapter introduces the most important functions and settings of the R&S SMBV100B step by step. The complete description of the functionality and its usage is given in the R&S SMBV100B user manual. Basic instrument operation is described in Chapter 8, "Instrument Control", on page 73.

Prerequisites

●

The instrument is set up, connected to the power supply, and started up as described in Chapter 4, "Preparing for Use", on page 17.

For the first signal generation tasks, you use the internal baseband and reference signal, so you do not need any additional signal source. More complex signal generation tasks, however, require an instrument equipped with additional options and/or external signals. Each task description lists its prerequisites.

The screenshots in this description show a fully equipped instrument. Consider that, the block diagram displayed on your particular instrument can differ from the one used in the example.

The instrument is manually operated via the touchscreen. Try out the following:

● Generating an Unmodulated Carrier...............................................................43

● Generating a Digitally Modulated Signal.........................................................46

● Triggering the Instrument with an External Signal...........................................48

● Enabling and Configuring a Marker Signal......................................................54

● Saving and Recalling Settings........................................................................ 58

● Generating an EUTRA/LTE Signal.................................................................. 61

6.1 Generating an Unmodulated Carrier

We start out by generating a simple unmodulated signal. The R&S SMBV100B in this example can be a base unit in its minimal configuration (i.e. with installed R&S SMBVB-B103).

6.2 Generating a Digitally Modulated Signal

This example shows you how to generate a simple WCDMA-3GPP (QPSK 45° offset) signal with the help of the "Custom Digital Modulation" functionality.

The minimum requirement for R&S SMBV100B in this example is a base unit equipped with:

●

Option custom digital modulation R&S SMBVB-K520

●

Option frequency R&S SMBVB-B103.

The initial situation is not the instrument's preset state but rather the configuration described in Chapter 6.1, "Generating an Unmodulated Carrier", on page 43.

1. In the block diagram, select "Baseband" and navigate to the section "Misc > Custom Digital Mod...".

The "Custom Digital Modulation" dialog opens.

2. In the "Custom Digital Modulation" dialog, select "General > Set according to Standard > WCDMA-3GPP".

3. Select "General > State > On" to enable signal generation.

Figure 6-4: Block diagram: Generating a digitally modulated signal

6.3 Triggering the Instrument with an External Sig-

nal

The example configurations are rather theoretical cases, because you rarely use the R&S SMBV100B as a standalone instrument. Usually, the instrument would be connected to a device under test (DUT) and/or other measurement equipment. As a rule, whenever a test setup requires two or more devices, provide them with a common reference frequency. Some test setups require control of the signal generation start and an exact generation start time, determined by a defined trigger event. For example, by triggering the instrument internally or externally from the DUT.

This example illustrates the general principle of external triggering and extends the configuration performed in Chapter 6.2, "Generating a Digitally Modulated

Signal", on page 46 by the configuration of the required trigger signal and con-

nector settings.

Triggering the Instrument with an External Signal

To start the signal generation synchronous to an external global trigger signal

The configuration requires three main steps with the following goals:

1. Observe the current connector configuration. Define an input connector for the external global trigger signal. See "To verify the current connector configuration" on page 49

2. Configure the baseband to use this external global trigger signal as trigger source. See "To reconfigure the trigger settings" on page 51

3. Connect the instrument and the external trigger source. See "To connect the instrument and the external trigger source" on page 53

To verify the current connector configuration

Trying Out the Instrument

The R&S SMBV100B is equipped with multipurpose bi-directional User connectors. Because the signal direction, input or output, and the signal mapping are configurable, we recommend that you check the current configuration before cabling or further instrument's configurations.

1. To display an overview of the current mapping of the logical signals to the connectors, perform one of the following:

● In the block diagram, select the Trigger/Marker/Clock status LEDs on the

left side of the "Baseband" block.

● Select "Baseband > Trigger Marker Clock".

Trying Out the Instrument

The "Global Connectors" dialog displays the current connectors configuration. The settings are configurable, but in this example we use the default mapping.

3. Alternatively, select "Block Diagram > Baseband > Misc > Custom Digital Mod", select the "Trigger In" tab and select "Global Connector Settings".

In the current mapping, the two global connectors User x on the front panel are configured as follows:

● "Marker 1/2" are output at the User 1/2 connectors

● The User 3 connector is an input for the "Global Trigger" signal.

Find the physical location of each connector

Use the built-in "Trigger Marker Clock > Show" function to display the location of the selected connector. A blinking marker on the front/rear panel view also indicates the selected connector.

To reconfigure the trigger settings

We assume that the instrument is configured as described in Chapter 6.2, "Gen-

erating a Digitally Modulated Signal", on page 46 and the default connector map-

ping is maintained (see Figure 6-5).

1. In the block diagram, select "Baseband > Misc > Custom Digital Mod > Trigger In".

2. Select the following settings:

Triggering the Instrument with an External Signal

To connect the instrument and the external trigger source

1. Use a suitable cable to connect the external trigger source to the User 2 connector of the R&S SMBV100B. See Figure 6-6.

Figure 6-6: Simplified representation of a test setup**

** = The figure depicts the cabling as a general principle; particular test setups do not require

all connections at the same time

The Figure 6-6 depicts the location of the connectors and explains the connection as principle. In practice, you would rather "substitute" the analyzer by a DUT, like a base station (BS). Other than in the example, the DUT can be the source for the reference signal. Instead of using an external trigger source, the DUT can also send, for example, a frame trigger signal to the R&S SMBV100B. The R&S SMBV100B acts still as the signal source.

6.4 Enabling and Configuring a Marker Signal

Test setups often require that an external device is synchronized to the generated data stream. For this purpose, the R&S SMBV100B can output marker signals (or markers) also to the generated signal. The R&S SMBV100B provides several regular marker signals and marker signals specific to the firmware option. With suitable marker settings for instance, you can mark slot or frame boundaries or mark the start of a particular modulation symbol.

This example extends further the configurations performed in Chapter 6.2, "Gen-

erating a Digitally Modulated Signal", on page 46. We assume a default connector

mapping (see Figure 6-5).

This test setup requires one oscilloscope, like the R&S®RTO, as additional equipment.

1. In the block diagram, select "Block Diagram > Baseband > Misc > Custom Digital Mod > Marker" tab.

2. Select "Marker Mode > Marker 1 > Pulse" and "Divider = 32".

Generated is a periodic marker with marker frequency of 120 KHz. The signal is output at the User 1 connector of the R&S SMBV100B (see Figure 6-5).

3. Use a suitable cable to connect the User 1 connector of the R&S SMBV100B to the monitoring instrument, for example oscilloscope like R&S®RTO. See

Figure 6-7.

ics Display

It is often useful to check the spectra of the configured signals, before you enable the RF output of the instrument.

The R&S SMBV100B provides a build-in function to represent the generated signal on a graphical signal display. We demonstrate this feature by showing the characteristics at one particular point of the signal processing chain. You can, however, display the signal characteristics at other different stages.

This example shows you how to use this graphical display to verify the generated signal. Use the signal generated in Chapter 6.4, "Enabling and Configuring a

Marker Signal", on page 54.
