OPERATING PRECAUTIONS

This product has been designed and tested in accordance with IEC Publication 348 - 'Safety

Requirements for Electronic Measuring Apparatus'. To keep it in a safe condition and avoid risk of

injury, the precautions detailed in the WARNINGS below should be observed. To avoid damage to the

equipment the precautions detailed in the CAUTIONS should also be observed.

WARNING - ELECTRICAL HAZARDS

AC supply voltage. This equipment conforms with IEC Safety Class

meaning that it is provided

with aprotective earthing lead. To maintain this protection the mains supply lead must always be con-

nected to the source of supply via a socket with an earthing contact. Make sure that the earth protection

is not interrupted if the supply is connected through an extension lead or an autotransformer.

Before fitting a non-soldered plug to the mains lead cut off the tinned end of the wires, otherwise

cold flowing of the solder could cause intermittent contact.

Do not use the equipment if it is likely that its protection has been impaired as a result of damage.

Fuses. Note that there is a supply fuse in both the live and neutral wires of the supply lead.

only

one of these fuses should rupture, certain parts of the equipment could remain at supply potential.

Make sure that only fuses of the correct rating and type are used for replacement. Do not use

mended fuses or short-circuited fuse holders.

To provide protection against breakdown of the supply lead, its connectors (and filter if fitted), an

external supply fuse with a continuous rating not exceeding

6 A

should be used in the live conductor (e.g.

fitted in the supply plug).

Removal of covers. Disconnect the supply before removing the covers so as to avoid the risk of

exposing high voltage parts.

any internal adjustment or servicing has to be carried out with the supply

on. it must only be performed by a skilled person who is aware of the hazard involved.

Remember that capacitors inside the equipment. including any supply filter capacitors, may still be

charged after disconnection of the supply. Those connected to high voltage points should be discharged

before carrying out work inside the equipment.

WARNING - OTHER HAZARDS

Parts of this equipment are made from metal pressings, therefore it should be handled with due

care to avoid the risk of cuts or scratches.

Some of the components used in this equipment may include resins and other materials which give

off toxic fumes if incinerated. Take appropriate precautions, therefore, in the disposal of these items.

This equipment has a lithium battery which if incorrectly handled could cause

danger to health or

safety - refer to the Service Manual for safe handling precautions.

CAUTION - LCD HANDLING

When using this equipment take care not to depress the front or rear faces of the display module as

this may damage the liquid crystal display elements.

CAUTION - STATIC SENSITIVE COMPONENTS

This equipment contains static sensitive components which may be damaged by handling - refer to

the Service Manual for handling precautions.

GENERAL INFORMATION

FEATURES

Performance

The 6313 is a programmable sweep generator with a range of 10 NIHz to 26.5 GHz.

It provides a combination of frequency and power sweeps with a typical accuracy

of 20 MHz and ±0.4 dB. When used with Marconi Instruments' 6500 Automatic

Amplitude Analyzer it forms a scalar measurement system with a private GPIB to

enhance the performance of the 6500, as well as a system GPIB to allow operation as part

of a complete automatic test system.

Control and display

Logically arranged keypads. with step keys and a rotary control allow rapid manual

operation. A large, backlit LCD display shows operating status, current values of

controlled parameters, and the current functions of four 'soft' keys. The 6313 can also be

fully controlled via the GPIB.

GENERAL INFO~MAT10N

Soft keys and configuration keys

In normal operation, some or all of the four soft keys have one operating parameter

assigned to each of them. Selection of a soft key allows the value or state of the

parameter associated with it to be changed.

Parameters are assigned to the soft keys according to which 'configuration' (group

of parameters) has been selected.

There are fifteen pre-programmed configurations currently available on the 6313,

for example:

Configuration Associated parameters

[FI - F2] Start frequency eFI), stop frequency (F2)

power level (PI), sweep time (TIME).

Internal/external sweep (sweep), sweep trigger

(swp_tr), single sweep initiation (s_swp),

counter trigger (cntr_tr).

The pre-programmed configurations are accessed by labelled 'configuration keys'.

Additionally, there are six 'user-programmable' keys, which allow you to store and access

your own configurations to match a particular application (see 'User programming').

[SWPfTRG]

Operating mode/sweep configurations

There are four basic operating modes:

1) Frequency sweep at constant power.

2) Frequency sweep with power slope.

3) Constant frequency and power.

4) Constant frequency with power sweep.

The frequency sweep can be defined either between lower and upper limits

(Fl -

F2) or as a frequency span about a centre frequency (CF - ~F). These two alternatives

for the definition of the frequency sweep give a total of six 'sweep configurations', each

accessed by a labelled configuration key.

Markers

Up to five frequency markers may be set within a sweep. These enable you, for

example, to stop the sweep at some nominal frequency and accurately measure that

frequency using a counter. Another application is the setting of secondary limits within

the total sweep, to allow both in-band and out-of-band testing.

Memories

Twenty non-volatile memories can each store complete sweeper settings.

The contents of the memories can be reviewed one after the other using the step

keys or rotary control. While reviewing the memories, the RF output is switched off to

avoid any risk of damage to sensitive test pieces.

GENERAL

INFO~MATION .

Any memory setting can be chosen as the power-up condition, so that repetitive

testing can begin immediately after switch-on.

User programming

The PROG key enables you to create and store (in non-volatile memory) up to six of

your own configurations. These can then be accessed via the six 'user-programmable'

configuration keys.

Applications of this facility include the ability to further simplify operation by

masking non-critical parameters and adding relevant parameters which could otherwise

only be accessed by selecting another configuration key. A real-time clock can also be

added to the display to allow the timing of a test procedure.

If required, all frequency information may be removed from the screen for security.

User calibration

The output power and frequency of 6313 may be simply re-calibrated to match

special measurement conditions. A complete user calibration might be necessary, for

example, where a long cable intervenes between the 6313 and the test piece, or where

there is a high ambient temperature. A limited calibration can also be performed over a

specified part of the sweeper's frequency range.

Using Marconi Instruments RF Power Meter 6960 or

6960A

(with Sensor 6913) and

the 26.5 GHz Microwave Counter 2442 connected to 6313's Private GPIB, full re-

calibration takes approximately 20 minutes.

Two sets of complete user calibration data and two sets of limited calibration data

can be held in non-volatile store while the primary calibration is also retained.

User calibration is only allowed after entry of special authorization codes which are

contained in a document which accompanies each sweeper. The primary calibration is

doubly protected in this way. All re-calibration may be disabled by the setting of an

internal switch.

The display indicates whether primary, user or limited calibration is in use.

Scalar analysis

The 63J 3 with Marconi Instruments' 6500 Automatic Amplitude Analyzer form a

complete scalar network analysis system.

Measurements which can be made include:

Return loss

Voltage Standing Wave Ratio (VSWR)

Gain

Insertion loss

Gain compression

Absolute power

Connection between the 6313 and the 6500 via the Private GPffi allows intelligent

interaction between the instruments which greatly enhances the performance of the 6500.

Details of the operation of the 6313 with the 6500 are given in Chap. 3-4.

GENERAL INFORJVlATION

System GPIB operation

Over 170 commands allow full control via the system GPIB. In addition to those

commands which are equivalent to front panel key operations, others allow fast data

transfer, text display and other facilities.

RF generation

The 6313 uses fundamental YIG tuned oscillators operating in the bands 2-8 GHz,

8-12.4 GHz and 12.4-20 GHz and 20-26.5 GHz. These provide the sweeper with a very

pure output having low harmonic and sub-harmonic components. Coverage to 10 MHz

is achieved by employing a frequency down-converter in conjunction with the 2-8 GHz

oscillator. All four YIG oscillators are kept running while the sweeper is switched on to

increase stability and reduce band switching times. Switching between oscillators is by

means of a PIN switch which gives a typical band switch delay of 0.5 IJ.S. The levelling

circuit uses a wide band coupler and detector diode for the 2 GHz to 26.5 GHz band and

an additional coupler/diode for the 10 MHz to 2 GHz band.

Digital correction data for all significant frequency values and power levels are

stored in memory, and applied to the sweep.

The FM input allows direct access to the YIG oscillators so that external frequency

locking devices may be used.

The RF on/off key has an integral LED to indicate whether or not the output is

enabled. The LCD gives an UNLV (unlevelled) display

the output power is no longer

levelled; for instance if the output power is greater than the set power level at low power

levels, or less than the set power level at high power levels. UNLV is also displayed when

the output is switched off. Levelled power is guaranteed over the range -5 to +10 dBm

(+7 dBm above 18 GHz).
