.

Basic safety instructions

1. The product may be operated only under
the operating conditions and in the
positions specified by the manufacturer. Its
ventilation must not be obstructed during
operation. Unless otherwise specified, the
following requirements apply to
Rohde & Schwarz products:
prescribed operating position is always with
the housing floor facing down, IP protection
2X, pollution severity 2, overvoltage
category 2, use only in enclosed spaces,
max. operation altitude 2000 m above sea
level, max. transport altitude 4500 m above
sea level.
Unless specified otherwise in the data
sheet, a tolerance of ±10% shall apply to
the nominal voltage and of ±5% to the
nominal frequency.

2. Applicable local or national safety
regulations and rules for the prevention of
accidents must be observed in all work
performed. The product may be opened
only by authorized, specially trained
personnel. Prior to performing any work on

the product or opening the product, the
product must be disconnected from the
supply network. Any adjustments,
replacements of parts, maintenance or
repair must be carried out only by technical
personnel authorized by Rohde & Schwarz.
Only original parts may be used for
replacing parts relevant to safety (e.g.
power switches, power transformers,
fuses). A safety test must always be
performed after parts relevant to safety
have been replaced (visual inspection, PE
conductor test, insulation resistance
measurement, leakage current
measurement, functional test).

3. As with all industrially manufactured goods,
the use of substances that induce an
allergic reaction (allergens, e.g. nickel)
such as aluminum cannot be generally
excluded. If you develop an allergic
reaction (such as a skin rash, frequent
sneezing, red eyes or respiratory
difficulties), consult a physician immediately
to determine the cause.

1171.0000.42-03.00 Sheet 2

Safety Instructions

4. If products/components are mechanically
and/or thermically processed in a manner
that goes beyond their intended use,
hazardous substances (heavy-metal dust
such as lead, beryllium, nickel) may be
released. For this reason, the product may
only be disassembled, e.g. for disposal
purposes, by specially trained personnel.
Improper disassembly may be hazardous to
your health. National waste disposal
regulations must be observed.

5. If handling the product yields hazardous
substances or fuels that must be disposed
of in a special way, e.g. coolants or engine
oils that must be replenished regularly, the
safety instructions of the manufacturer of
the hazardous substances or fuels and the
applicable regional waste disposal
regulations must be observed. Also
observe the relevant safety instructions in
the product documentation.

6. Depending on the function, certain products
such as RF radio equipment can produce
an elevated level of electromagnetic
radiation. Considering that unborn life
requires increased protection, pregnant
women should be protected by appropriate
measures. Persons with pacemakers may
also be endangered by electromagnetic
radiation. The employer/operator is
required to assess workplaces where there
is a special risk of exposure to radiation
and, if necessary, take measures to avert
the danger.

7. Operating the products requires special
training and intense concentration. Make
certain that persons who use the products
are physically, mentally and emotionally fit
enough to handle operating the products;
otherwise injuries or material damage may
occur. It is the responsibility of the
employer to select suitable personnel for
operating the products.

8. Prior to switching on the product, it must be
ensured that the nominal voltage setting on
the product matches the nominal voltage of
the AC supply network. If a different voltage
is to be set, the power fuse of the product
may have to be changed accordingly.

9. In the case of products of safety class I with
movable power cord and connector,
operation is permitted only on sockets with
earthing contact and protective earth
connection.

10. Intentionally breaking the protective earth
connection either in the feed line or in the

product itself is not permitted. Doing so can
result in the danger of an electric shock
from the product. If extension cords or
connector strips are implemented, they
must be checked on a regular basis to
ensure that they are safe to use.

11. If the product has no power switch for
disconnection from the AC supply, the plug
of the connecting cable is regarded as the
disconnecting device. In such cases, it
must be ensured that the power plug is
easily reachable and accessible at all times
(corresponding to the length of connecting
cable, approx. 2 m). Functional or
electronic switches are not suitable for
providing disconnection from the AC
supply. If products without power switches
are integrated in racks or systems, a
disconnecting device must be provided at
the system level.

12. Never use the product if the power cable is
damaged. Check the power cable on a
regular basis to ensure that it is in proper
operating condition. By taking appropriate
safety measures and carefully laying the
power cable, ensure that the cable cannot
be damaged and that no one can be hurt by
e.g. tripping over the cable or suffering an
electric shock.

13. The product may be operated only from
TN/TT supply networks fused with max.
16 A (higher fuse only after consulting with
the Rohde & Schwarz group of companies).

14. Do not insert the plug into sockets that are
dusty or dirty. Insert the plug firmly and all
the way into the socket. Otherwise, this can
result in sparks, fire and/or injuries.

15. Do not overload any sockets, extension
cords or connector strips; doing so can
cause fire or electric shocks.

16. For measurements in circuits with voltages
V

> 30 V, suitable measures (e.g.

rms

appropriate measuring equipment, fusing,
current limiting, electrical separation,
insulation) should be taken to avoid any
hazards.

17. Ensure that the connections with
information technology equipment comply
with IEC 950/EN 60950.

18. Unless expressly permitted, never remove
the cover or any part of the housing while
the product is in operation. Doing so will
expose circuits and components and can
lead to injuries, fire or damage to the
product.

R&S SMR Putting into Operation

1 Putting into Operation

This chapter contains all information about putting into operation (unpacking, connection to AC supply,
switching on and off), functional testing and installation of the instrument, preset settings and views of
the front and rear panel showing the controls and connectors needed for operation.

General Instructions

Before putting the R&S SMR into operation, please make sure that

• the covers of the casing are put on and screwed,

• the ventilation openings are free,

• no signal voltage levels exceeding the permissible limits are applied at the inputs,

• the outputs of the instrument are not overloaded or connected incorrectly.

If these points are not observed, the instrument might be damaged.

Unpacking the Instrument

 Take the instrument out of the shipping box and check whether the

items listed in the packing list and in the lists of accessories are all
included.

 Remove the two protective caps from the front and rear of the

remove protective cabs

Should the instrument be damaged, immediately notify the forwarder who shipped the instrument to you
and keep the box and packing material.

For further transport or shipment of the R&S SMR the original packing should also be used. It is
recommended to keep at least the two protective caps for front and rear side in order to prevent
damage to the controls and connectors.

R&S SMR and carefully check the instrument for damage.

Setting up the Instrument

For applications in the laboratory or on a work bench, it is recommended that the support feet on the
bottom of the instrument be extended. For the LCD display, this provides the optimum viewing angle
which typically ranges from perpendicular to the display front to approximately 30° below.

WARNING

1134.9108.12 E-1 1.1

The feet must be fully folded in or out. Only in this way can the stability of SML be
guaranteed and reliable operation be ensured. With the feet out, the weight of other
units put onto SML must not exceed 30 kg. The units must be secured against
slipping (eg by locking the feet of the unit at the top side of the enclosure).

When shifting the unit with the feet out, the feet might collapse and fold in. To avoid
injuries, the unit must therefore not be shifted with the feet out.

Putting into Operation R&S SMR

Supply Voltage

The R&S SMR can be operated at a.c. systems from 100 to 120 V and 200 to 240 V at system
frequencies from 50 to 60 Hz. The power supply socket is situated at the rear of the instrument. The
instrument automatically sets itself to the voltage applied within the permissible voltage ranges. It is not
necessary to set the instrument to a certain supply voltage.

How to Ensure EMC

In order to avoid electromagnetic interference, the instrument may only be operated when it is closed
and with all shielding covers fitted. Only appropriate shielded signal and control cables may be used.

Power Fuses

The R&S SMR is protected against short circuits by means of two fuses according to nameplate of the
power supply. The fuses are situated in the draw-out fuse holder which is inserted close to the power
supply socket (see below).

Power supply socket

I

On/Off switch at the front of the instrument

Initial Status

Upon switching on, the instrument automatically assumes the status which was set when it was
switched off.
If the instrument need not to be operated from the initial status any further, a defined default status
should be established by pressing the [PRESET] key prior to further settings.

Frequency accuracy after switching on when the oven-controlled reference oscillator is fitted
(option R&S SMR-B1)

Switch on:  Press switch.
The instrument is ready for operation.

Switch off:  Release switch.

The reference oscillator needs some minutes of warm-up time to reach its nominal frequency. During
this period of time, the output frequency does not yet reach its final value either. In the status line in the
header field of the display the message "OVEN COLD" is displayed for this time.

1134.9108.12 E-1 1.2

R&S SMR Putting into Operation

RAM With Battery Back-Up

The R&S SMR has a static read-write mem ory (CMOS-RAM) with battery back-up, in which 50 different complete
settings of the instrument can be stored (cf. Chapter 3, section "Storing and Calling of Instrument Settings"). In
addition, all data and/or lists the user enters him self, such as for list mode, mem ory sequence, and user correction
of the level, are stored in the RAM. Further, all data of the calibrations running within the instrument in the
R&S SMR are stored in the RAM (cf. Chapter 4, section "Calibration" and Service Manual Instrument). A
lithium battery with a service life of approx. 5 years serves to supply the RAM with power. When the battery is
discharged, the data stored will be lost. Exchanging the battery is described in the Service Manual Instrument.

Preset Setting

A defined setting status is achieved by pressing the [PRESET] key.

Preset Status:

RF frequency 10 GHz
RF level -20 dBm
Reference frequency internal, adjustment off
Offsets 0
Modulations switched off
Transient-free level setting switched off, level attenuator mode: Auto
Internal level control level Alc: On
User correction level Ucor: Off
LF output switched off
Sweep switched off
List mode switched off
Memory sequence switched off
Suppression of indications system security: unaltered
Protection of calibration data protection lock: unaltered
Settings stored unaltered
Data, lists etc. stored unaltered
IEC-bus address unaltered

All parameters and circuit states, even those of operating modes which are not activated, are preset by
means of Preset. The presettings going beyond the above list can be seen from the menu
representations as of Chapter 4 which each indicate the Preset setting status.

Functional Test

On switching on the instrument and permanently during operation, the R&S SMR carries out a self test. The ROM
contents as well as the battery of the non-volatile RAM are checked. The most important instrument functions are
automatically monitored during operation. If an error is detected, the message "Err" is displayed in the status line.
For further identification of the error, press the [ERROR] key. Thereupon a description of the error is displayed (cf.
Chapter 9, section "Error Messages"). Return to the menu exited by pressing the [BACK] key. If required, internal
test points can be polled by the user and the results be read out and displayed. Cf. Service Manual Instrument.

Mounting into a 19" Rack

CAUTION

The R&S SMR can be mounted into a 19" rack by means of rack adapter ZZA-94 (stock no. 396.4905.00).
The mounting instructions are attached to the adapter.

1134.9108.12 E-1 1.3

Ensure free air inlet at the perforation of the side walls and air outlet at the rear of the
instrument in rack mounting.

R&S SMR Design of the Display

3 Manual Operation

This chapter shows the design of the display and describes the manual control of the microwave signal
generator, for example calling up of menus, selection and editing of parameters, use of the list editor
and the SAVE/RECALL function. This chapter also contains an overview of menus showing the
functions available for the instruments and its options.

It is useful to read the sample settings for first users in Chapter 2, "Short Tutorial".

Fig. 3-1 Design of the display

(1) Header field

(2) Status line

(3) Menu fields

The header field of the display indicates frequency and level of the RF output
signal. In the RF-sweep operating mode, the start and stop frequencies are
displayed in two lines one above the other. The start and stop levels are indicated in
the LEVEL-sweep operating mode correspondingly. With User Correction On, the
current frequency and the corresponding correction value are indicated in two lines.

The status line indicates at the left the menu path of the current menu and at the

right the operating mode and operating state of the instrument. Error messages and
notes for caution are also displayed in the status line.

The indication fields below the status line are reserved for the menu

representations. The image contents of these fields change as a function of the
menu selected.

The lowest menu level shows the setting menu with the current settings of the
selected menu. Settings are made in select or input windows which open when the
current setting is activated.

Basic Operating Steps R&S SMR

Basic Operating Steps

To operate the instrument, menus are called in the display. All setting possibilities and the current
setting status are evident from the menus. All settings can be made by accessing the menus.
RF frequency and RF level can also be set without menu operation using keys [FREQ] and [LEVEL].
RF signal and modulation can also be switched on/off without menu operation using keys [RF ON/OFF]
and/or [MOD ON/OFF].

Calling the menus

Accessing the menus is effected using rotary knob [VARIATION], [SELECT] key and [BACK] key.

Rotary knob

[SELECT] key

[BACK] key

Settings are accessed in the setting menus ending with the right-hand display margin.

Rotary knob [VARIATION] moves the menu cursor over the positions of a menu level
to be selected.
If a scrollbar is visible at the right-hand margin of a menu, the menu is larger than
the screen window. If the menu cursor is moved to the margin of the screen window,
the covered lines become visible.

If the rotary knob is pressed after a position has been selected, the lower menu level
or the respective settings are called. The rotary knob hence has the same function
as the [SELECT] key.

If the rotary knob is pressed while [BACK] is selected, the menu cursor wraps back
to the menu last called.

The [SELECT] key acknowledges the selection marked by means of the menu
cursor. Depending on the position, the next lower menu level or the the respective
setting is called.

The [BACK] key

- returns the menu cursor to the next higher menu level; the menu cursor is shifted
to the left into the preceding column of the menu structure,

- resets the menu cursor from frequency or level value indication in the header field
into the menu field to the menu called last,

- closes the display pages called using keys [STATUS], [HELP] and [ERROR]
again.

R&S SMR List Editor

List Editor

The R&S SMR offers the facility of generating lists for automatic sequences (list mode, memory sequence)
or for user-defined level correction (Ucor). The lists consist of elements (pairs of values) which are defined
by an index and at least one parameter per index. Each list is assigned a separate name and selected by
means of this name. Access to the lists is made in the associated menus. For example, sequences of
frequency and level value pairs can be accessed in the List menu. How to generate and edit lists is
explained in detail in this section by the example of the List mode (List menu, see Fig. 3-3).

4 Instrument Functions

This chapter describes the functions of the instrument and its options which can be activated manually
via menus or by remote control (frequency and level settings, analog and digital modulations, sweep, list
mode, memory sequence and general functions not directly related to signal generation).

RF Frequency

The RF frequency can be set directly using the [FREQ] key or via the Frequency menu.

In the Frequency menu, the frequency of the RF output signal is entered and indicated under
Frequency.

In frequency settings made with the [FREQ] key, an arithmetic offset is taken into account. Such
settings are indicated in the header line of the display. This makes it possible to enter the desired output
frequency of subsequent units, if any (eg mixers). The offset and the multiplier can also be entered in
the Frequency menu (see next section: "Frequency Offset and Multiplier").

IEC/IEEE-bus command SOUR:FREQ:RCL EXCL

Frequency Offset and Multiplier

On the R&S SMR it is possible to enter an offset and a multiplier for subsequent units, if any, in the
Frequency menu. Such entries are taken into account in the frequency displayed in the header line,
which indicates the frequency of the RF signal at the output of the units in question (see Fig. 4-2). If both
a frequency offset and a multiplier have been entered, it is assumed for the calculation that the RF
signal is first multiplied and then the offset is added.

The frequency of the RF output signal in the Frequency menu is calculated from the frequency (display),
offset and multiplier values entered as follows:

The entry of an offset and multiplier causes a change of the frequency value displayed in the header line
(the value taking into account the offset is displayed). The value of the RF output frequency is displayed
under Frequency in the Frequency menu.

The entered offset remains active also for frequency sweeps.

R&S SMR RF Level

RF Level

The RF level can be set directly using the [LEVEL] key or via the Level - Level menu.

In the Level - Level menu, the set RF output level is entered and indicated under Amplitude.

In level settings made with the [LEVEL] key, the offset of a subsequent attenuator/amplifier is taken into
account (see section "Level Offset"). This makes it possible to enter the desired level at the output of
subsequent units. The offset can also be entered in the Level - Level menu under Offset.

dBm, dBBV, mV and BV can be used as level units. The four unit keys are labelled with the respective
units. To change to another level unit, simply press the corresponding unit key.

Note: - The note "Unleveled" appears in the status line if the displayed level is not attained. The

maximum possible RF output level varies depending on the model and the options fitted

R&S SMR RF Level

Level Offset

On the R&S SMR, it is possible to enter an offset for a subsequent attenuator/amplifier, if any, in the Level
menu. The offset is taken into account in the display in the header line (see below), which represents
the level value of the signal at the output of the subsequent unit (see Fig. 4-4).

The level of the RF output signal is therefore calculated from the amplitude (display) and offset entered
in the Level - Level menu as follows:

RF output level = amplitude (display) - offset

The entered offset has no influence on the RF output signal of the R&S SMR; the offset is only taken
into account in the displayed level value. The value with the offset can be directly entered with the
[LEVEL] key.

The RF output level of the R&S SMR is indicated in the Level - Level menu.

attenuator (R&S SMR30, R&S SMR40).

With Attenuator Mode Fixed, non-interrupting level setting is performed. Electronic attenuator switching
is used instead of interrupting, mechanical attenuator switching.

If the level falls below the permissible variation range, the warning "Level underrange" is output in the
status line of the display; if it attains or goes beyond the upper limit value, the warning "Unleveled" is
output. With underrange or overrange, level accuracy and spectral purity are no longer guaranteed.

Switching On/Off Automatic Level Control (Alc)

Settings for automatic level control (ALC) can be made in the Level – Alc menu.

When level control is switched off (ALC State Off), switchover is made to a sample-and-hold mode. In
this mode, level control is switched on automatically for a short time after each level or frequency setting
and the level control is held at the value attained. Level control OFF is used in multisource
measurements to improve intermodulation suppression.

The basic functions of level control are shown in Fig. 4-5.

User Correction (Ucor)

The "User correction" function can be used to create and activate lists in which level correction values
are assigned to arbitrary RF frequencies.

Up to 10 lists with a total of 160 correction values can be compiled. For frequencies not included in the
list, level correction values are determined by interpolation based on the nearest correction values.

When user correction is switched on, Ucor (user correction) is displayed in the header field in addition to
the level. The RF output level is the sum of both values.

Level + Ucor = output level

If an offset is selected at the same time, the displayed level value is the difference between the
amplitude and the offset entered in the Level menu.

Amplitude  offset = level

With automatic level correction, the Ucor lists can be automatically filled with measured values.

Modulation - General R&S SMR

Modulation - General

In addition to pulse modulation (PULSE), the R&S SMR offers the following modulation types if it is fitted
with the option R&S SMR-B5:

• linear and logarithmic amplitude modulation (AM),

• frequency modulation (FM),

• digital modulation types (ASK and FSK).

For the analog modulation types, internal or external modulation sources can be used. For the digital
modulation types, only external modulation sources can be used.

Modulation Sources

Internal modulation source

For AM and FM, an internal modulation generator (Lfgen) is available. For more information see section
"LF Generator".

For internal pulse modulation, the instrument can be equipped with a pulse generator (option R&S
SMR-B14). For more information see section "Pulse Generator".

External modulation source

The input connectors to be used for feeding the various types of external modulation are listed in Table 4-1.
External AM and FM can be AC- or DC-coupled.

R&S SMR Modulation - General

External modulation signals should have a voltage of Vp= 1 V (V

= 0.707 V) to maintain the

rms

displayed modulation depth or deviation. Voltage deviations exceeding ±3% are displayed in the status
line as shown in Table 4-2.

Table 4-2 Status messages for deviation from nominal at external modulation inputs

Message Deviation

EXT1-HIGH “Input voltage at EXT1 too high“

EXT1-LOW “Input voltage at EXT1 too low“

EXT2-HIGH “Input voltage at EXT2 too high“

EXT2-LOW “Input voltage at EXT2 too low“

EXT-HI/HI “Input voltage at EXT1 and EXT2 too high“

EXT-LO/LO “Input voltage at EXT1 and EXT2 too low“

EXT-HI/LO “Input voltage at EXT1 too high and at EXT2 too low“

EXT-LO/HI “Input voltage at EXT1 too low and at EXT2 too high “

Simultaneous Modulation

Basically, any combination of AM, FM and pulse modulation is possible. There are restrictions only for
modulations of equal type (see Table 4-3).

Two-tone AM is possible by switching on both the external and the internal source.

Two-tone FM is possible by switching on both FM1 and FM2. For FM1 and FM2, separate deviations
can be set and separate sources switched on.

Note: For two-tone modulation it should be noted that the selected deviation or modulation depth

applies to only one signal in each case, and the sum deviation or sum modulation depth
results from the addition of the two signals. If the maximum value of deviation or modulation
depth is exceeded, overmodulation occurs.

Mutual Switch-Off of Modulation Types

Due to the multiple use of function modules in the instrument, some modulation types cannot be
activated simultaneously (see Table 4-3). With manual control, incompatible modulation types
deactivate one another, and a short-time warning message is output in the status line.

Note: IEC/IEEE-bus control according to SCPI does not allow the selection of incompatible

modulation types. With remote control, an error message is output when an attempt is
made to activate incompatible types of modulation (see Chapter 9).

[MOD ON/OFF] Key

The various types of modulation can be switched on and off directly using the [MOD ON/OFF] key or via
the Modulation menu. If switch-on is made using the [MOD ON/OFF] key, the modulation sources which
are set in the modulation menus are used.

The [MOD ON/OFF] key can be effective either for all types of modulation or only for a selected
modulation. The selection of modulation types for which the [MOD ON/OFF] key is to be effective is
made in the Utilities – Mod Key menu.

If only one type of modulation is selected, it is switched on or off each time the [MOD ON/OFF] key is
pressed.

If all modulation types are selected, the [MOD ON/OFF] key has the following effect:

• If at least one modulation type is active:

Pressing the [MOD ON/OFF] key switches off all active modulation types. The modulation types
which were active are stored.

• If no modulation type is active:

Pressing the [MOD ON/OFF] key switches on the modulation types that were last switched off with
this key.

R&S SMR Analog Modulation

Pulse Modulation

The pulse modulator can be controlled from an external source or by an internal pulse generator (option
R&S SMR-B14). With external control, the external source feeds the pulse modulator directly. The
envelope of the RF is identical to the control signal. With control by the internal pulse generator, the
pulse shape of the pulse generator determines the envelope of the RF. The pulse delay, pulse width and
pulse period can be set.

The polarity of pulse modulation is selectable. With Pulse Polarity = Normal, the RF level is switched on
if HIGH level is present at the PULSE modulation input. If option R&S SMR-B14 is fitted, the input
impedance can be switched between 50  and 10 k; if the option is not fitted, the input impedance is
permanently at 50 .

Settings for the pulse modulation and the pulse generator can be made in the Modulation - Pulse menu.

Pulse Generator

As an internal modulation source, the pulse generator (option R&S SMR-B14) offers the possibility of
setting single and double pulses with variable pulse delay, pulse width and pulse period. The pulse
generator can be triggered internally or by an external signal at the PULSE input. The following Pulse
modi can be selected: Auto Trig, Ext Trig, and Ext Gated (see Fig. 4-13 to Fig. 4-15). The internal trigger
signal is derived from the reference frequency and hence very stable. In the trigger mode Ext Trig, the
positive or the negative edge can be used for triggering the pulse generator. In the trigger mode Ext
Gated, the pulse generator is triggered as long as an active Gate signal arrives at the PULSE input.

The pulse generator can also be used as an independent unit, ie without the pulse modulator being
controlled if the pulse modulation source (Pulse Source) is switched to OFF or EXT. The pulse can be
tapped at the VIDEO output.

Sweep R&S SMR

Sweep

The R&S SMR features digital, step-by-step sweep for the following parameters:

• RF frequency

• LF frequency

• RF level

In addition to digital step-by-step sweep, analog ramp sweep for the RF frequency and RF level is
possible.

A sweep is set in five basic steps, which are demonstrated by the following example, ie the setting of a
frequency sweep:

 Set sweep range (Start Freq and Stop Freq or Center Freq and Span).

 Select linear or logarithmic sweep (Spacing).

Only with LIN/LOG:

 Select step size (Step Lin) and dwell time (Dwell).

Only with Ramp:

 Select sweep time (Sweep Time).

 Activate marker if desired (Marker).

 Switch on sweep (Mode set to Auto, Single or Step).

Setting the Sweep Range (Start Freq, Stop Freq, Center Freq, Span)

The sweep range for RF sweeps can be entered in two ways. Either the Start Freq and Stop Freq are
entered or Center Freq and Span. Please note that the two parameter sets mutually affect each other as
follows:

Start Freq altered: Stop Freq = unaltered

Center Freq = (Start Freq + Stop Freq)/2
Span = (Stop Freq – Start Freq)

Stop Freq altered: Start Freq = unaltered

Center Freq = (Start Freq + Stop Freq)/2
Span = (Stop Freq – Start Freq)

Center Freq altered: Span = unaltered

Start Freq = (Center Freq – Span/2)
Stop Freq = (Center Freq + Span/2)

Span altered: Center Freq = unaltered

Start Freq = (Center Freq – Span/2)
Stop Freq = (Center Freq + Span/2)

1134.9108.12 E-2 4.24

R&S SMR Sweep

Selecting Linear/Logarithmic Sweep (Lin, Log, Ramp Spacing)

Linear, logarithmic or ramp sweep can be selected with Spacing. For RF and LF sweeps, both the linear
and logarithmic modes are selectable. For level sweeps, only the logarithmic mode is possible.

With logarithmic sweeps, the step size (Step) is equal to a constant fraction of the current setting. The
logarithmic step size for RF and LF sweeps is entered in % and for level sweeps in dB.

With ramp sweep, the sweep time is set instead of the dwell time.

Operating Modes (Mode)

The following sweep modes are available:

Auto

Step

Ext Single

Sweep from start point to stop point with automatic restart at start point. If another
sweep mode was active prior to selection of the auto mode, the sweep is continued
from the setting active at that time.

modes or stops the sweep in all modes.

Sweep Outputs

The outputs X-AXIS, V/GHz, BLANK, MARKER and Z-AXIS at the rear of the instrument are available
for controlling and triggering oscilloscopes or XY recorders.

X-AXIS

V/GHz

BLANK

MARKER

Z-AXIS

With the sweep switched on, this output supplies a voltage ramp of 0 to 10 V for the
X deflection of an oscilloscope or an XY recorder.

This output supplies a voltage which is proportional to the frequency. The slope,
either 0.5 V/GHz or 1 V/GHz, corresponds to a range of 5 mV to 10 V or 10 mV to
20 V for 10 MHz to 20 GHz. A slope of 5 V/GHz is available above 20 GHz (R&S
SMR27/R&S SMR40). The slope can be set under Utilities - AuxIO - V/GHz. The
voltage is always available, even with the sweep switched off.

This output supplies a signal (0 V/5 V) for triggering and blanking an oscilloscope or
for PEN LIFT control of an XY recorder. The signal duration can be set under Utilities

- AuxIO - Blank Time.

This output becomes active when the sweep run has reached the marker. The
MARKER signal can be used for brightness control of an oscilloscope. Up to
10 markers can be set to mark positions in the sweep run. The duration of the active
signal is equal to the dwell time (DWELL) of a step.

This output generates a pulse of –5 V if the MARKER output is active and +5 V if the
BLANK output is active. The Z-AXIS signal can be used for the combined blanking
and marker generation for network analyzers.
