Before putting the SMP 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.
1.1.1 Supply Voltage
The SMP can be operated at a.c. systems f rom 90 to 132 V and 180 to 265 V at system frequencies from 47 to 440 Hz. The power supply socket is s ituated at the rear of the instrument. The instrum ent 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.
1.1.2 Power Fuses
The SMP is protected against short c ircuits by means of two fus es acc ording to nam eplate of the power supply. The fuses are situated in the draw-out fuse holder which is inserted between power supply socket and power switch (see below).

Putting into Operation SMP
1.1.4 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.
STANDBY Mode
In the STANDBY mode the optional reference oscillator (option SM-B1) remains switched on, which increases frequency accuracy.
Frequency accuracy after switching on when the oven-controlled reference oscillator is fitted (option SM-B1)
When switching on from the STANDBY mode, the specified frequency accuracy is reached immediately. If the power switch was switched off, the ref erence oscillator needs som e 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 mess age "OVEN COLD" is displayed for this time.
1.1.5 Setting Contrast and Brightness of the Display
Brightness control Contra s t cont ro l
Contrast and brightness of the display can be set by means of the contrast and brightness controls situated below the display.
1.1.6 RAM With Battery Back-Up
The SMP has a static read-write memory (CMOS-RAM) with battery back-up, in which 50 different complete settings of the instrument can be stored (cf. Chapter 2, section "Storing and Calling of Instrument Settings"). In addition, all data and/or lists the user enters himself, such as for list mode, memory sequence, and user correction of the level, are stored in the RAM. Further, all data of the calibrations running within the instrument in the SMP are stored in the RAM (cf. Chapter 2, section "Calibration").
A lithium battery with a service life of approx. 5 years serves to s upply the RAM with power. When the battery is discharged, the data stored will be lost. Exchanging the battery is described in Chapter 4.

1.1.7 Preset Setting
A defined setting status is achieved by pressing the [PRESET] key.
Preset Status:
RF frequency 10 GHz RF level -30 dBm
(-20 dBm without option SMP-B15/B17, Attenuator) 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 PLL bandwidth auto 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 Beeper 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 repr esentations as of Section
2.4 which each indicate the Preset setting status.
1.2 Functional Test
On switching on the instrument and perm anently during operation, the SMP carries out a self test. T he ROM contents as well as the battery of the non-volatile RAM are checked on switching on the instrument and the RAM contents with every calling the memory. The most important instrument functions are automatically monitored during operation.
If an error is detected, the m essage "ERROR" is displayed in the status line. For further identification of the error, press the [ERROR] k ey. Thereupon a description of the err or/s is displayed (cf. Chapter 2, section "Error Messages"). Return to the menu exited by pressing the [RETURN] key.
If required, the self tests can be induced purposefully. See section "Functional Test". Further, internal test points can be polled by the user and the results be read out and displayed. See section "Voltage Indication of Test Points".

Fitting the Options SMP
1.3 Fitting the Options
Due to its variety of options, the SMP offers the possibility of providing the instrument with the equipment exactly corresponding to the application. Newly fitted options are automatically recognized and the relevant parameters added in the menu.
After every change of the instrument conf iguration, the CMOS RAM has to be cleared as the storage data shift:
À Switch off the instrument À Switch the instrument on again with the [RESET] key pressed
The internal calibration routines YFOM, ALC AMP and PULSE GEN now have to be called up again to restore the cleared calibration values. These routines are accessible via menu UTILITIES-CALIB (see Section "Calibration" and service manual). The calibration routines have to be carried out in the following order:
1. YFOM
2. ALC AMP
3. PULSE GEN (if installed)
1.3.1 Opening the Casing
Remove paneling À Remove four screws in the two tilt feet at the rear of the instrument.
À Remove the upper paneling towards the top and rear. À Turn the instrument. À Remove the lower paneling towards the top and rear.

Set tuning voltage and calibrate OCXO
The crystal oscillator was factory-tuned to nominal frequency and the appropriate tuning voltage indicated on the cover of the m odule. The calibration value now has to be calculated from this value and transferred to the memory of the signal generator.
1035.5005.02 1.5 E-8
Fitting the Options SMP
Calculate calibration value The tuning voltage is generated by a 12b-bit-D/A converter which is
scaled such that a tuning voltage of 12 volts is generated with calibration value (CALIBRATION DATA) 4000. The calibration value is thus calc ulated from the tuning voltage (V as follows
CALIBRATION DATA = V
For checking purposes, the voltage at pin 16 of plug X710 on the motherboard can be rem easured and corrected if necessary. A check by means of frequency measurement may only be made after a warm-up of 2 hours and against a calibrated reference.

SMP Basic Operating Steps
2.2.2 Basic Operating Steps
The operating principle is explained in this section. For better understanding, please read sections "Display" and "Sample Setting for First Users" in addition.
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 oper ation using keys [RF ON /OFF] and/or [MOD ON/OFF].
2.2.2.1 Calling the Menus
Accessing the menus is effected using rotary knob [VARIATION], [SELECT] key and [RETURN] key.
Rotary knob
Rotary knob [VARIATION] moves the menu cursor over the positions of a menu level to be selected.
If a scrollbar is visible at the left-hand mar gin of a m enu, the menu is larger than the screen window. If the menu cursor is moved to the m argin of the scr een window, the covered lines become visible.
[SELECT] key [RETURN] key
The [SELECT acknowledges the selection marked by means of the menu cursor. The [RETURN] 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.
Settings are accessed in the setting menus ending with the right-hand display margin.

2.2.4 List Editor
The SMP offers the possibility to generate lists. Lists are used for setting sequences (LIST mode or memory sequence), or f or level correction which can be defined by the user (UCOR) . They consist of elements which are defined by an index and at least one parameter per index. Each list is m ark ed by a separate name and can be selected via this name. The lists are acc essed in the menus assigned in each case, e.g. to the settings sequences of frequency and level value pairs in the LIST menu. However, the lists are always generated and processed in the same way and the procedures are hence explained in detail by the example of the mem ory sequence mode (menu MEM SEQ ) in this section. A pattern setting at the end of this section allows the user to become fam iliar with the operation of the list editor.
Setting menus providing list processing are structured in two pages: The first page, called OPERAT ION page in the following contains the gener al configuration parameters
for processing a list. Further , the general list functions s uch as selecting and deleting the list as well as calling an editing mode are provided. The second page, the EDIT page, is autom atically displayed when calling an edit function and serves to enter and modify the parameters of the list.
The OPERATION page has a similar arrangement with all list editors. As an ex ample, the O PERATION page of the MEM SEQ menu is shown:

2.4.1 Frequency Offset and Multiplier
The SMP offers the possibility of entering an offset and multiplier of possibly series-connected instruments in the FREQUENCY menu. T he indication/input value under FREQUENCY considers this entries and represents the frequency value of the RF signal at the output of these instruments (cf . Fig. 2-17). If frequency offset as well as multiplier have been entered, it is taken for gr anted in c alculating the values that the RF signal is multiplied first and then the offset is added.
Hence the frequency of the new RF output signal is calculated from the entries FREQUENCY, OFFSET and MULTILIER according to the formula:
RF-output frequency = (FREQUENCY – OFFSET) / MULTIPLIER
Offset and multiplier entries do not have an inf luenc e on the RF output signal of the SMP. I. e., an entry does not change the RF-output frequency but only the FREQUENCY value indicated in the FREQUENCY menu.
The RF output frequency of the SMP is indicated in the header field of the display. It can be entered directly using the [FREQ] key, i.e. without considering the offset and multiplier.
The offset setting also remains effective with the frequency sweep.

The RF output level can be set directly using the [LEVEL] key or by accessing the LEVEL menu. In the header field of the display, the set RF output level is indicated under LEVEL. The input value of level settings opened using the [LEVEL] key directly cor responds to the RF output
level. The input value of the level settings effected in the LEVEL-LEVEL menu mathematically consider s the

This offers the possibility of entering the desired level at the output of series-connected instruments, the SMP then alters the RF output level correspondingly. The offset can als o be entered in the LEVEL-LEVEL menu.
dBm, dBµV, mV and µV can be used as level units. The 4 unit keys are directly labeled with these units.
In order to change to another level unit, simply press the desired unit key.

2.5.1 Level Offset
The SMP offers the possibility of entering the offset (OFFSET) of a possibly series-connected attenuator/amplification element in the LEVEL-LEVEL menu. The indication/input value under AMPLITUDE considers this input (s ee below) and represents the level value of the signal at the output of the series-connected instrument (cf. Fig. 2-19).
The level of the RF-output signal is thus calculated fr om the input values AMPLITUDE and O FFSET in the LEVEL-LEVEL menu according to the formula:
RF-output level = AMPLITUDE – OFFSET
Entering an offset value does not aff ec t the RF-output s ignal of the SMP. I.e., an entry does not c hange the RF-output level but only the displayed AMPLITUDE value in the LEVEL-LEVEL menu.
The RF output level of the SMP is indicated in the header field of the dis play. It can be entered directly, i.e. without considering an offset, using the [LEVEL] key.

In the ATTENUATOR MODE FIX ED operating mode, level settings ar e carried out without interruption. An attenuation is set electronically instead of using the interrupting attenuator.
The 20-dB range of the level which can be set interr upt-free extends from the level s et on switching on the ATTENUATOR FIXED MODE to 20 dB below. Within this 20-dB range, the level can be set by means of the keyboard, the rotary knob or via IEC/IEEE-bus.
Outside the 20-dB range, levels are set via the interrupting mechanical attenuator. Relative to this new level, a new level in the range of 0 to –20 dB is set interrupt-free again.

2.5.3 Level Control (ALC)
Menu LEVEL-ALC offers access to settings for level control. Level control can be deactivated and various bandwidths of the level control can be switched on. Switching off level control (ALC STATE OFF) switches over the internal level control into a
sample-and-hold operation. In this operating m ode, level control is autom atically switched on for a short period of time after every level and frequency setting, and then the level control is held at the value achieved. Switching off the level control is used with multi-transmitter m easurem ents to achieve a larger intermodulation ratio.

2.5.4 User Correction (UCOR)
Function "User Correction" can be used to create and activate lists in which ar bitrar y RF frequencies ar e assigned level correction values.
Up to 10 lists with a total of 160 correction values can be compiled. For frequencies which are not included in the list the level correction is determ ined by means of interpolation of the neares t correction values.
When user c orrection is switched on, the LEVEL indication is c ompleted by the indication UCOR (User Correction) in the header field of the display. The RF output level is the sum of both values.
Output Level = LEVEL + UCOR
If the offset setting is used at the same time, the LEVEL indication value is the difference of the input values AMPLITUDE and OFFSET of the menu LEVEL.

2.6 Modulation
The SMP offers the following modulations:
Amplitude modulation (AM)
Logarithmic amplitude modulation (AM)
Frequency modulation (FM)
Phase modulation (PM) *
Pulse modulation (PULSE) *
Digital modulations (ASK and FSK) *only with options fitted
Internal or external modulation sources can be used for the analog modulations. Digital modulations require an external modulation source.
2.6.1 Modulation Sources
Internal Modulation Sources
Internal modulation generators LF GEN1 and LF GEN2 are available for AM, FM and PM depending on the equipment. For a more detailed description, cf. Section "LF Generator".
For internal pulse modulation, the instrument can be equipped with a pulse generator (option SMP-B14). For a more detailed description, cf. Section "Pulse Generator".
External Modulation Sources
The input sockets appr opriate for the various modulations in the cas e of external supply can be taken from table 2-1. External AM, FM and PM can be AC or DC-coupled.

p
= 0.707 V) in order to maintain
rms
the modulation depth or frequency deviation indicated. Deviations of m ore than ±3 % from the rated voltage are signaled in the status line by means of the following messages (cf. table 2-2).
Table 2-2 Status messages in the case of a deviation from the rated value at the external
modulation input
Message Deviation

EXT1-LOW Voltage at EXT1 too low

EXT-LO/LO Voltage at EXT1 and EXT2 too low
EXT-HI/LO Volt age at EXT1 too high and EXT2 too low
EXT-LO/HI Voltage at E XT1 too low and EXT2 too high
2.6.1.1 Simultaneous Modulation
Basically, every combination of AM, FM and pulse modulation is possible. Instead of FM, phase modulation (PM) can be switched on as well. There are only restrictions for m odulations of the same kind and for the multiple use of the 2nd LF generator (cf. table 2-3).
Two-tone AM is possible by simultaneously switching on the external and internal source. Two-tone FM or two-tone PM is possible by simultaneously switching on FM1 and FM2 or PM1 and
PM2. For FM1 and FM2 (PM1 and PM2) separate deviations can be set and separate sources switched on.
Note: W ith two-tone modulation please observe that the set deviation or modulation depth is valid for
one signal and the sum deviation or sum modulation depth is determined by adding both signals. This results in overmodulation if the maximum value for deviation or modulation depth is exceeded.
2.6.1.2 Alternate Switching Off of Modulations
Due to the multiple use of som e functional modules in the instrument s ome m odulations cannot be s et at the same time (cf. table 2-3). In the case of manual c ontrol, incom patible modulations deactivate one another, a short-time warning is displayed in the status line.
Note: The IEC-bus control according to SCPI forbids the mutual influence of types of modulation on
one another. In the case of remote control, an error message is output when an attempt is made to switch on incompatible types of modulation (cf. annex B).

2.6.1.3 [MOD ON/OFF] Key
The modulations can directly be switched on/ off using the key or by accessing the MODULATION menu. W hen switching on using the [MOD ON/OFF] key, the modulation sources which are s et in the modulation menus are used.
The [MOD ON/OFF] key can either be eff ective for all modulations or for a selected m odulation. The selection for which modulation the [MOD ON/OFF] k ey is effective is m ade in the UT ILITIES-MOD KEY menu.
Once a certain type of modulation has been selected, it is switched on or off each time that the [MOD ON/OFF] key is pressed.
If "all modulations" are selected, the [MOD ON/OFF] key has the following effect:
At least one modulation is active:
Pressing the [MOD ON/OFF] key switches off all active modulations. Which modulations were active is stored.
No modulation is active:
Pressing the [MOD ON/OFF] key switches on the modulations which were last switched off using the [MOD ON/OFF] key.

2.6.2.5 Pulse Modulation
The pulse modulator can be c ontrolled by an external source as well as by the internal pulse generator. In the case of external control, the exter nal source directly feeds the pulse m odulator. The envelope of the RF is identical to the control signal. In the case of control by the internal pulse generator, the pulse form of the pulse generator determ ines the envelope of the RF. Puls e delay, pulse width and period can be set.
The polarity of the pulse modulation is selectable. W ith POLARITY = NORM, the RF level is on with HIGH level at modulation input PULSE. W ith option SMP-B14, the input impedance can be s witched between 50 Ω and 10 k Ω. If no option is fitted, it is fixed to 50 Ω.
Note: Option SMP-B12, pulse modulator, improves the measured data in the frequency domain
beyond 2 GHz. Option SMP-B13, pulse modulator 0,01 to 2 GHz, allows pulse modulation in the frequency range between 0,01 and 2 GHz.
2.6.2.5.1 Pulse Generator
As an internal modulation source, the pulse generator (option SMP-B14) offers the possibility to set single and double pulses with variable pulse delay, pulse width and period. The pulse generator can be triggered internally or by means of an external signal at the PULSE input. The internal triggering is derived from the ref erence frequency and hence very stable. In trigger mode EXT, the positive or the negative edge can be used to trigger the pulse generator.
The pulse generator can also be operated as an independent function without the pulse modulator being controlled if the pulse modulation source SOURCE is switched to OFF or EXT. T he puls e c an be tapped at the VIDEO output.
