2.2 Wiring
For installation of the EB200 in a rack there is connector X13 available for connecting the antenna
(antenna connector can be internally selected).
The external speaker output is activated by setting an internal jumper which automatically sets the
internal speaker out of order.

4052.2000.02 2.3 E-7.1
2.3 Pin assignment of the connectors
For the pin assignment of the connectors refer to interface description 4052.2000.01 SB in the annex.
2.4 Operation with Battery Pack EB200BP
The battery pack incorporates two 12V nickel metal hydride accumulators Energizer NJ1020.
It can be charged via incorporated power sup ply input or via connector DCX1 at the rear pan el of the
EB200, while the unit is on or off. The accumulators are charged one after another.
Before starting operati on, the state of the accum ulators must be check ed by pres sing 2
. If required, the
accumulators must be charged.
If the accumulators are c harged, the LEDs 25, 50, 75 and 100 are o n after pressing 2
indicating the
existing capacity.
If the accumulators are discharged the LED at 25 is flashing after pressing 2
.
If the accumulators ar e over-discharged, all LEDs re main off after pressing 2
. This is indicated in the
menu SETUP POWER by NOT FIT.
Over-discharged accumulators can only be charged when the
EB200 is switche d off or directly via the connec tor at the battery
pack (1
).
If charging doesn’t take place (after a charging period of 1 hour
there is no capacit y change being indicated after pres sing 2
) the
accumulators must be taken out and put in again by exchanging
positions.
Note:
If the unit can’t be operated despite max. capacity being indicated
there can be an erroneous reaction of the accumulator controller.
Possible remedy: The accumulators must be taken out and put in
again by exchanging positions.
Operation with only one accumulator is also poss ible.
Charging can only take place at a temperature range of 0°C to +45°C.
Charge voltage range : +22V to +26V
Discharge temperature range :
−10°C to +55°C
Storage temperature range :
−20°C to +55°C
Self discharge increases heavily with higher storage temperatures.
The SETUP POW ER menu shows the dc power supply source of the EB200 with the status of the

Note:
When you press the keys MOD, BW, MGC, SQU, TONE, ATT, AFC and LEV on c e, the nex t selec ti on is
activated. The displaye d window shows the already changed sett ing. Thus the unit can be operated
blindfold.
3.4.1 MOD key (modulation modes)
Selection of modulation mode by the + or – function of the key: FM, AM, PULSE, CW, USB, LSB, IQ
When you press this key, the pulldown menu shown below with a number of items for selection is
displayed. When you press the key once, the next selection is activated. In a pulldown menu, the
currently selected modulation mode is shown in inverse video.
When you press the ke y once agai n the n ex t item is selected. There is no s top to t he tog gle f unc ti on, so
when the end of the menu is r eached in either directio n the next step leads to the opp osite end of the
menu.
The pulldown menu disappears after approx. 2 to 4 seconds or if any other key is pressed.
3.4.2 BW key (bandwidths)

4052.2000.02 3.14 E-7
3.4.3 MGC-SQU-TONE keys and the VAR potentiometer
All three functions ca n be turned on or off . In the ON st ate, a settin g value can be assign ed. This v alue
can be adjusted with the VAR potentiometer (on the left next to the volume control).
The functions are indep endent and switching on one f unction need not necessarily have an ef fect on
another.
The following applies to all three functions:
When you press a ke y (MGC, SQU or TO NE), the function is turned on and, at the sam e time, the
digital pot for adjusting the associated setting value is activated.
The lettering (MGC, SQU or TONE) and the presentation of the value in inverse video indicate that
variation with the digital pot has been selected.
If the function has alread y been selected and the s ame ke y is pressed again, the f unction is turned off .
The following is then displayed in the appropriate field:
MGC OFF (= AGC)
SQU OFF
TONE OFF
When you press a key, one of the three functions goes from the OFF-state to the ON-state and is
simultaneously selected, the selection of one of the other two functions being cancelled.
The values are displayed in dBµV.
MGC key
Switching the MGC function on or off (switch over from MGC to AGC)
MGC is short for M
anual Gain Control (gain control by potentiometer).
AGC is sh ort for A
utomatic Gain Control
The MGC or AGC status (corresponds to MGC off) is presented below the MGC key on the display.
If MGC is selected, MGC is displayed with a value between -30 and 110.
The unit of the MGC value is dBµV.
SQU key
Turning the squelch function on or off
The SQU status is presented below the SQU key on the display.
If SQU is turned off, SQU OFF is displayed.
If SQU is turned on, SQU is displayed with a value between -30 and 110 (threshold value).
The unit of the SQU value is dBµV.
Page 29
EB200 Manual Operation
4052.2000.02 3.15 E-7
TONE key
Turning the tone function on or off
The TONE status is presented below the TONE key on the display.
If TONE is turned off, TONE OFF is displayed.
If TONE is turned on, TONE is displayed with a value between -14 and 94 (tone reference value).
The unit of the TONE value is dBµV.
-14 dBµV = minimum level -30 dBµV + 16 dB
94 dBµV = maximum level at ATT ON 110 dBµV - 16 dB
Starting from this value, the level sc ale is expa nded i n the ran ge -15 t o +15 dB an d the le vel m agnit ude
is represented by the pitch of a tone (0 dB corresponds to about 400 Hz). The TONE function is a
frequency tone, proportional to the input level.
3.4.4 ATT key (attenuator)
Multiple toggle ON, OFF, AUTO for the function that connects the 30 dB attenuation path.
The selected function is displayed.
In the AUTO position the attenuation path is switched on immediately before the tuning limit of the
IF unit is reached and with a hysteresis of 7 dB it is switched off again.
One can recognize the instantaneous condition by the scaling of the level bar indirectly. See also
"Level display" on page 8.
Page 30
EB200 Manual Operation
4052.2000.02 3.16 E-7
3.4.5 AFC key (automatic frequency control)
Turning the AFC function on or off
When the AFC is on, the lettering is in inverse video.
After pressing the AF C key (automatic f requency control) the fr equency of the receiv er is followed up
automatically to a changing signal frequency. The range of the AFC corresponds approx. to the
selected IF-bandwidth . At built up AFC the offset ind ication (TUNING) is centered. The AFC function
can be activated at AM, FM and PULSE.
Note:
The AFC is only effective above a particular bandwidth-dependent signal level. With the squelch being
switched on the signal level must be above the squelch response threshold.
3.4.6 LEV key (level indicator)
Multiple toggle PEAK, AVG, FAST
The selected function is displayed.
3.4.7 SAVE and RCL keys (memory functions)
Writing to and reading from memory locations
With SAVE, the receiver settin gs are tr a ns f er red to t he memory location. The c onf iguration of the SAVE
key determines on which memory location the settings are stored (see also "
ROLLKEY
configuration" on page 52).
With, RCL the contents of the memory location with the number shown in the MEM window are
transferred to the receiver.
If a number was entere d before SAVE or RCL were pres sed, then this num ber will be in terpreted as a
memory location number (see also "KEYS" on page 52).
Page 31
EB200 Manual Operation
4052.2000.02 3.17 E-7
3.5 Decimal keypad
Keys 0 to 9, decimal point and Enter key (ENT)
The effect of pressing the ENT key is to store the value in the editor as the currently selected
parameter.
As there is no CLR ke y and no +/- ke y, these functions are im plemented as softk eys in the temporar y
editor (see "POP-UP editor" on page 21).
3.6 Spinwheel (rotary pulse generator)
The spinwheel excites 24 bursts per spin and has a magnetic indexing mechanism.
In the configuration menus, the spinwheel is used for the change of selected parameters.
The spinwheel is genera ll y used t o set r ecei ve fr equenc ies in th e m enus. D iff erent progr essi ons can be
selected in the m enu SETUP: KEYS. For the tun in g of the f r equ ency in a channel s pac ing an inc rement
per spinwheel burst can be defined through INCR VALUE.
3.7 Keys for selecting the spinwheel functions
FRQ and MEM are selecti on keys with a fixed par ameter assignm ent. They also act as Enter k eys for
these parameters.
FRQ Key for entering receive frequencies
MEM Key for selecting the memory location (0 to 999)
LOCK Key for enabling and disabling the spinwheel functions
Example:
By entering the number 78 with the dec imal keypad and then pressing the MEM k ey, you can select
memory location 78. The frequency can also be selected independently at the same time with the
spinwheel, if the FRQ field is active.
Pressing the MEM and F RQ keys only causes a switc hover of the spinwheel function, if a numerical
entry has not been made previously.
If the FREQ key is pressed whenever a receive frequency has alre ady been selected then the rec eive
frequency is rounded off to the next channel spacing. The channel spacing can be set in the menu
SETUP: KEYS through parameter INCR VALUE (see also KEYS on page 52).
At the top right of the LCD, there is a field which displays the current status of the spinwheel function:
At this point, the designation of a configuration parameter can also be displayed (see "Select key (SEL)"
on page 18).
If LOCK is displa yed, the spinwheel has b een deactivated. If you now turn the spinwhee l, the display
will flash.
Page 32
EB200 Manual Operation
4052.2000.02 3.18 E-7
3.8 Memory functions
If you want to modif y the contents of a memor y location, the contents of the m emory location must be
transferred to the receiver with RCL (see "SAVE and RCL keys (memory functions)" on page 16),
modified with the hardk eys or softke ys in RX-CONF (see "RX- CONF (receiver conf iguration)" on page
36) and stored again with SAVE.
The SAVE and RCL (recall) keys are used to read and write receiver states from and to the 1000
memory locations.
The setting and resetting of memory locations is handled by softkeys in the M-CONF menu.
The display window f or the memory locations also cont ains a s ymb ol with f eatur es that indicate whether
the memory location is full, or empty, or set, or not set, for polling (see "Symbols" on page 11).
3.9 Menu-control keys
The SEL key is used to select parameters in the configuration menu.
Toggle and increment or decrement functions can be operated by means of the spinwheel.
3.9.1 Softkeys
The functions of the softkeys are determined by the current menu status. The softkey labelling is
provided by the LCD field above each key.
3.9.2 Escape (ESC)
When the ESC key is pressed once, one step is taken up the menu tree.
This key is used to abort the editor.
Temporary windows (eg error messages) are also closed.
3.9.3 Select key (SEL)
The SEL key is used to select parameters in the configuration menu.
When a configuration m enu is entered, the selector always jum ps to the parameter which was edited
last.
The short designation of the selected parameter (eg F-START, F-STOP, F-STEP, T_DWELL,
T_SIGNAL etc) is disp layed in the spinwheel selector window, provided that the spin wheel functions
have not been cancelled with LOCK.
If LOCK has been activated and the editor has been started by entering a number, the selector is
nevertheless displayed in the spinwheel window provided that the editor is open.
If the spinwheel is turned in that state, LOCK flashes.
Page 33
EB200 Manual Operation
4052.2000.02 3.19 E-7
3.9.4 Relationship between the FRQ, MEM, SEL and LOCK keys
FRQ and MEM are selection keys with permanently assigned parameters. Their function does not
depend on the menu status.
The SEL key is an alternative to the FRQ and MEM keys
Example:
If FRQ is pressed in a co nfiguration menu, the selec tion of the current param eter is overridden and it
becomes possible to tune the receive frequency with the spinwheel. When the SEL key is pressed,
selection is switched back to the previous configuration parameter.
In every case, the LOC K key disables t he spinwheel. The LOCK state do es not have an y influence on
the SEL function.
3.10 TEST key
The "short test" is run while the key is held down.
During the "short test" an amplitude modulated line spectrum (64-MHz grid) is fed-in behind the antenna
input and the receiver is tuned to the line frequency which is the closest to the current receive
frequency. Then the c omplete receive-pa th from the antenna i nput of the tuner is measured up to th e
AF-processing and weigh te d.
If all data are within the perm issible limits, the message "TEST OK SIGNAL PATH" is output. If th e
measured level is not in the expected range, the message "SENSITIVITY OUT OF RANGE" is output.
3.11 ON/OFF switch
The toggle switch turns the operating v oltage to the E B200, which is generated b y a DC/DC convert er,
on or off.
The backlit LCD indicates when the EB200 is ON.
The selected parameters are stored.
3.12 Contrast control
The contrast control is used to set the vertical reading angle for the LCD display, to adapt it to the
workplace and to compensate for the temperature dependence of the LCD. This function cannot be
altered from the menus.
3.13 VAR pot (MGC, SQU, TONE)
The digital potentiom eter which has 24 switch pos itions per turn is used to vary the MGC, the sque lch
threshold and the tone values. The value in inverse video is the one that can be varied with the pot.

When one of the decim al keys (0 to 9 and the d ecimal point) is pres sed for the first tim e, a temporar y
EDIT window is displayed above the softkey bar; all numerical entries are shown in this window.
The EDIT window does not have preferr ed values. An except ion is the MHZ and th e KHZ key. These
two keys will only be displayed if the spinwheel function is connected to a frequency.
If a time parameter was selected, the time units SEC and MSEC are presented as ENTER keys.
While the editor window is open, you can continue to use the spinwheel to adjust the selected
parameter (e.g. FRQ or F-START).
Value transfer with the ENT key
When the Enter key is pressed, the value becomes the value of the parameter displayed in the
spinwheel select or window. Either FRQ or MEM is displayed in the spinwheel s elector window or the
name of a selected parameter from the configuration menu.

3.16.1 Softkeys in the editor window
MHZ softkey
The basic unit of all fr equencies is alwa ys MHz. From that th is sof tkey has the s ame im portance as the
ENT key does.
KHZ softkey
The principal units i n all menus are alwa ys MHz. To make kHz entries easier, a KHZ s oftkey has also
been provided. Press ing the KHZ key multiplies the entered value by a factor of 10
-3
and transfers it
(Enter function). If the selected parameter is not a frequency, the KHZ softkey is disabled and not
displayed.
SEC softkey
The basic unit of all tim es is always seconds. From that this softkey has the sa me importance as the
ENT key does.
MSEC softkey
The basic unit of all tim es is always seconds . In order to f acilitate the input of millisecon ds, there is th e
MSEC softkey in additio n. This caus es that the entered v alue is m ultiplied by the fac tor 10

and taken
over (enter function). If the selected parameter is not a time, no MSEC softkey appears then.
<- softkey
The arrow key is used to clear falsely entered characters.
ESC softkey
The ESC softkey as well as the ESC key closes the editor window without any value being transferred.

3.17 Changing configuration parameter s
A selected parameter can be cha nged in the F- SCAN, M-SC AN and D-SC AN co nfigurati on menus and
in the SETUP submenus. Parameters can be selected by the SEL softkey.
Numerical and non-numerical parameters can be changed by the spinwheel and the decimal keypad.
In the case of non-num erical parameters, the digits ref erred to below are interpreted in the fol lowing
way:
‘0’ corresponds to OFF
‘1’ corresponds to ON
‘.’ corresponds to the infinity sign (for example with the parameter CYCLES)
As the EB200 does not have any CURSOR keys, toggle and increm ent or decrement functions are
implemented by means of the spinwheel.
In order to be able to also enter non-num erical par ameters when the s pinwheel is lock ed, the numbers
0, 1, 2, etc. refer to these param eters corres pondingly. T hus by pressing a num ber and the EN T button

The hold time T_NOSIG can well be used to skip non-speaking times in radio co mm unications . In order
to control the dwell time by a signal of an occupied channel, the parameter T_NOSIG is required
additionally. If a hold tim e is defined for the parameter T_NOSIG, the signal bit is queried during t he
normal dwell time T_DWELL in a periodical way. The signal bit corr es ponds to the s ignal on p in 6 of the
audio connector X8 at the rear pan el of the EB200 and indica tes whet her the insta ntaneous s ignal level
is above the squelc h value. If the signal b it disappears, the hold t ime is activated. After the hold time
has elapsed the scanning will continue with the next frequency. If, however, the signal bit emerges
during the hold tim e again, the hold time is stopped and the disappear ance of the signal is waited for
again. Thus the hold time behaves lik e a monoflop th at can be retriggered and abort the nor mal dwell

space with MTIME.
D-SCAN SPEED Scan speed: MTIME PER CHANNEL /LOW / NORMAL / HIGH
In the position MTIME PER CHANNEL the hard war e suppor t ed s wee p mechanism of the DSCAN is not
used, but a step-b y-step increm enting of the frequency as in the F-SCAN. That way it is possible to
carry out the level m easurem ent with a def ined meas uring tim e for each chan nel. T his operation m ode
is suitable for the m easurement of impulsive noises with s imultaneous representation of the spectrum
on the display of the EB200.
The digital scan ca n not be stopped in h is procedure. Therefor e the generated data can dis appear, if
they are not picked up f ast enough at the r emote control i nterface. The m aximum data quantit y at the
remote control interface can be determined indirectly by setting the DSCan speed.
The position NORM AL corresponds to an average speed with which under good preconditions all
resulting data can be passed on through the Ethernet interfac e by means of TCP to a n a ppl ication. This
is the default setting after the switch-on of the EB200 and corresponds to the DSCan speed
corresponding to the firmware versions up to V01.07.
The position LOW corres ponds to a speed, that is for instance ar ound the factor 10 sm aller than in the
position NORMAL. T he maxim um data quantit y limit is arou nd 6 Kb yte/s. W ith this setting it is possible
to transfer all data via the RS232 PPP interface by means of UDP.
The position HIGH corresponds to the maximum speed. The data quantity can amount up to 320
Kbyte/s. The resulting data can be transmitted then only through the Ethernet interface and by means of
UDP to an application.

CYCLES Number of sweeps 1 to 1000 / infinite
REF LEVEL The reference level determines t he largest level va lue to be represented. It ca n
be set in the range of 0 to 110 dBµ V in steps of 10 dB. Also intermediat e values
can be set via remote control or by means of direct number input.
DISPLAY LIMITS Display range of the spectrum: eg –20 dBµV to 60 dBµV
Initially the upper value of the DISPLAY limits is firmly linked to the reference level.
If, however, the SW option EB200FS (Field Strength Measurement) is fitted, the upper value of the
DISPLAY LIMITS can b e configur ed indepen dent of the r eference le vel. In t his case it can be var ied in
the range from 0 to 250 dB in 10-dB inc rements. Shifting the disp lay range to values near 250 dB is
only necessary if very high antenna k-factors are to be taken into account.
The lower value is calculated from the upper value of the DISPLAY limits minus the current RNG.
Note:
In D-SCAN the measuring time is only important when it comes to setting the D-SCAN SPEED to
MTIME PER CHANNEL. In this case frequency scanning will in fact be performed, the r esults being
shown in a spectrum. A meas uring time other than the DEFAULT can only be adjus ted with IF sec tions
that are fitted with the DDC2 (see also "SYSTEM menu" on page 40).
3.18.3.2 D-SCAN cycle
When D-SCAN (digita l scanning) is running ( RUN is shown in inver se video), the synthesizer is being
tuned to the exact f requency of the channels. C hannel spacing always equ als half the IF bandwidth.
The level of each c hannel is being m easured. The displa yed spectrum is der ived from the sum of the
measured levels
The number of channels is derived from the span frequency divided by half the IF bandwidth. The
higher the number of channels is, the longer takes the D-SCAN cycle.
3.18.3.3 Spectrum display NORM (normal)
The display alwa ys shows a s pectrum of 190 level lines according to its pix el res olutio n and it do es not
depend on the number of channels. If the number of channel exceeds 190, the measured values of
several channels will be combined in a way that the respective highest level will be displayed. The
frequency of the channel with the highest level will be stored in the background so that the correct
frequency can be set for the marker-to-peak process.
However, through the rem ote control interface, all m easured channels are always outp ut. In this case
the representation reduced to 190 lines is not available.
If the number of channels is sm aller than 190, sever al level li nes will get th e same length f rom which a
spectrum of rough steps is derived.
The level is ind icated by 35 pixels in the y-axis. The r esolution can be set in four s teps by the RNG
softkey. In order to avo id overdriving of the rec eiver, the reference l evel is set to the highes t expected
positive signal level. Every desired reference level can be set via remote control by command
VOLTage:AC:RANGe in the range of 0 to 110 dBµV.

3.18.3.4 Spectrum display NORM with squelch on
When the squelch is set on, the sque lch line is displayed at a y-position corresponding to the s quelch
value. Furthermor e the f unction of the marker-to-peak softk e y is extended s o tha t every time the softkey
is pressed, the mark jumps to the next signal maximum above the squelch line, one after another.
3.18.3.5 Spectrum display in STOP mode
If a spectrum was ge nerated and displayed in th e RUN mode and STOP is pres sed then the current
spectrum will be frozen. The receiver sets the mark frequency. By pressing marker-to-peak softkey
there will be a jump to the next signal maximum which can be listened to.
3.18.3.6 Spectrum display DIFF (differential mode)
Every time being in th e RUN mode when there will be a c hange-over from NORM to DIFF, the last
spectrum will be intern all y stored as a refer ence spec tr um and the diff erentia l dis pla y will be set o n. For
this spectrum the last stored reference spectrum will be subtracted from the current one and the
resulting level lines will be displayed with cor rect signs. Thus new signals will be displ ayed as positive
and missing signals as negati ve level l ines. T he y-sca ling is s et to -/+ ½ of the RNG valu e regard less of
the RNG softkey setting . W ith squ elc h of f , the marker-to-peak sof tk e y lets the m arker frequency jump to
the absolute level maximum. With squelch on, the marker frequency will jump to the next level
maximum with a positive deflection above 5 dB.

LONGTEST Starts a complete unit testing procedure
At the LONGTEST all test spectrum lines are scanned. At first two runs with attenuator and the
bandwidth 150 kHz and/or 15 kHz are carried out. With that the preselection is bypassed first and
feeding-in takes place d irectl y at the Fronten d. If both of the runs suppl y an error-f ree result, a thir d run
with disconnected atten uator is carried out. If also this run does not supply any errors, a short test is
carried out with the current receive frequency.
As a result the OK message "TEST OK , RF RANG E AND SIGNAL PATHES" or an error report is
output. The error reports are determined as follows:
1. or. 2. test run reports errors:
If all measuring fr equencies report errors the message "SENSIT IVITY OUT OF RANGE" is ge nerated.
Otherwise it is check ed whether all measurem ent points produce err ors at a specific band width. In this
case the message "IF PR EFILTER WIDE DEFECT IVE" or "IF PREFI LTER NARROW DEFECT IVE" is
generated.
If the error fits into neither category a list with up to 4 faulty frequencies and an error message lik e eg
"LEVEL TOO HIGH AT 128 MHZ" is output.
1st and 2nd test runs do not report any error, 3rd test run reports error:
If all measuring fr equencies report errors the message "SENSIT IVITY OUT OF RANGE" is ge nerated.
Otherwise error m essages for those pres electi on rang es ar e gener ated in the f requency range of which
faulty measuring points are located.

4.1 Introduction
The device is equipp ed as standard wit h an RS232 int erface. The 9- pin connector X9 is located at the
rear of the device. The TCP/I P protocol with PPP is applied to this interface. From firmware version
2.31 onwards, this interface can also be configured for the RS232 standard (see menu
SETUP:REMOTE and Appendix A).
The device can be equippe d optionall y with a LAN interfac e EB200 R4. The 8-pin RJ45 connector X91
is located at the rear of the device. The TCP/IP protocol is run on this 10 MBIT Ethernet interface.
The device supports the SCPI command syntax of version 1993.0 (S
tandard Commands for
P
rogrammable Devices). The SCPI standard is based on IEEE 488.2 and is aimed at standardizing
device-specific commands, error handling and status registers (see "Notation" on page 13).
This section assum es basic knowle dge of program m ing and opera tion of the c ontr oller. A des cripti on of
the interface commands is to be obtained from the relevant manuals.
The requirements of the SCPI standard for command syntax, error hand ling and configuration of the
status registers are ex pla ined i n the rel evant s ectio ns. T ables pr ovid e a fas t over vie w of the c om m ands
implemented in the de vice and the b it assignm ent in the status reg isters. The ta bles are supp lemented
by a comprehensive description of every command and the status registers. Detailed programming
examples of the main f unc tions are to be found in Annex D. Annex C cont ains a r eference list for all unit
functions in manual and remote control with all the relevant references to the manual.
4.2 Brief instructions
4.2.1 Remote control via RS232 interface
The default values of the interface parameters of the EB200 are configured by host name and IPaddress, respectively.
192.0.0.2 and port: 5555
For more information see annex A, interfaces.
1. Connect the EB200 and the controller by using the modem bypass cable RS232 stipulated for
WindowsNT.
2. The RAS service has to be installed on the controller.
3. The PPP-connection to the controller is set up by starting the EB200.PBK file.
4. The ping command is a s imple wa y to check whether the controller is ab le to make connection to the
EB200. Just enter the command “ping <IP-Address>“ (eg “ping 192.0.0.2“) in the DOS box.
5. Comm ands can be sent to and m essages can be received from the EB200 by means of a T elnet
application which is started and configured with the interface parameters of EB200.
6. To tes t the connection, *idn? can be entered, for example, to quer y the EB200 identification. The
response string should then be displayed.
Page 76
EB200 Manual Remote control
4052.2000.02 4.2 E-7
4.2.2 Remote control via LAN interface (option)
The default values of the interface parameters of the EB200 are configured by host name and IPaddress, respectively.
89.10.11.23 and port: 5555
For more information see Annex A, interfaces.
1. Connect the EB200 and the controller by using an Ethernet cable with RJ45 connectors. For
direction connection to a net work adapter card use a cross-cable. If the EB200 is connected to a
network either via a hub or directly, a 1-to-1 cable is required.
2. On the controller TCP/IP must be installed. The network adapter card must be set to half-duplex.
3. When the EB200 is opera ted within a network , is must be set to a network -compatible IP address .
The network administrator will be able to provide further information on this. Also see Annex D.
4. The ping command c an be us ed t o eas i l y chec k whether the control ler is ab le to make connection to
EB200. Just enter the command “ping <IP-Address>“ (eg “ping 89.10.11.23“) in the DOS box.
5. By using a Telnet application conf igured with the inter face parameters of EB200 comm ands can be
sent to and responses be received from EB200.
6. To test the connection, *idn? can be entered, for example, to query the EB200 identification.
Note:
If previously a connection had been made to another unit with the same IP address, it may be
necessary to delete the corresponding entry in the ARP table by entering t he command “ARP -d <IP
address>“ in the DOS box.
4.3 Configuring the remote control
The device can at the sam e time be operat ed via the f ront panel and the rem ote-control i nterface. T his
operation is called "c ompeting c ontrol" and is characte rized by the f act that both t he local opera tor and
a detached operator have full access to all device functions. Moreover, any operator setting can be
monitored by the remote-control interface.
"Competing control" can b e switched over in favour o f remote control via the re mote control comm and
System:Klock ON (see Annex A). In this cas e, m anual c ontrol is full y disab led a nd has to be enab led
by the remote-control System:Klock OFF.
4.3.1 Setting the IP-A and port number
If EB200 is equ ipped with the remote-control inter face EB200R2 (RS232 interf ace) parameters baud
rate, IP address and port number can be set in submenu SETUP REMOTE.
The setting of the IP ad dress and the port num ber becomes immediatel y effective. After changi ng the
baud rate, the device must be switched on/off.

4.4 Structure and syntax of the device messages
4.4.1 SCPI introduction
SCPI (Standard Commands for Programmable Devices) describes a standard command set for
programming devices, irrespective of the type of device or manufacturer. The goal of the SCPI
consortium is to standardi ze the dev ice-specif ic comm ands to a large exte nt. For this purpos e, a model
was developed which defines the same functions inside a de vice or for different devices. Comm and
systems were gener ated whic h are as s igned to these functions. Thus it is possibl e to ad dres s the s ame
functions with identical commands. The command systems are of a hierarchical structure. Fig. 4-1
illustrates this tre e structure using a section of com mand system SENSe which operates t he sensor
functions of the devices. The other examples regarding syntax and structure of the commands are
derived from this command system.
SCPI is based on stan dard IEEE 488.2, ie it uses the sam e syntactic basic elements as well as the
common commands defined in this standard. P art of the s yntax of the de vice res ponses is def ined with
greater restrictions than in standard IEEE 488.2 (see "Responses to queries" on page 8).
4.4.2 Structure of a command
The commands cons ist of a so-called h eader and, in m ost cases , one or m ore par am eters. Header and
parameter are separated by a "white space" (ASCII code 0 to 9, 11 to 32 decimal, eg blank). The
headers may consist of sever al k eywords. Q ueries are f ormed by directl y appen ding a questi on m ark to
the header.
Note:
The commands used in the following examples are not in every case implemented in the device.
Common commands Common comm ands consist of a header preceded by an asterisk "
*"
and one or several parameters, if any.
Examples:
*RST RESET, resets the device
*ESE 253 EVENT STATUS ENABLE, sets the bits of
the event status enable register
*ESR? EVENT STATUS QUERY, queries the
contents of the event status register.
Page 78
EB200 Manual Remote control
4052.2000.02 4.4 E-7
Device-specific commands
Hierarchy: Device-specific co mmands are of hierarchical str ucture (see Fig. 4-1).
The different levels are rep resented by combined headers . Headers of
the highest level (root level) have only one keyword. This keyword
denotes a complete command system.
Example: SENSe
This keyword denotes the command system
SENSe.
For commands of lower levels, the com plete path has to be s pecified,
starting on the left with th e highest leve l, the individua l keywords being
separated by a colon ":".
Example:
SENSe:FREQuency:STARt 118 MHz
This command lies in the t hird level of the SENSe system. It sets the
starting frequency of a scan to 118 MHz.

Some keywords occur at severa l leve ls with in one c omm and s ystem. Their
effect depends on the str ucture of the command, that is to sa y, at which
position in the header of a command the y are inserted.
Example: OUTPut:OUTPut:SQUelch:STATe ON
This command contains the keyword STATe at the third
command level. It defines the state of the SQUelch function.
OUTPut:FILTer:LPAS:STATe OFF
This command contains the keyword STATe at the fourth
command level. It defines the state of the AF filter.
Optional keywords: Some c ommand s ystems perm it certain ke ywords to be optiona lly inser ted
into the header or omitted. These keywords are marked by square
brackets in the descript ion. The full command lengt h must be recognized
by the device for reas ons of compatibility with the SCPI s tandard. Some
commands are considerably shortened by these optional keywords.
Example: [SENSe]:FREQuency[:CW]: STEP [:INCRement]
25 kHz
This command sets the stepwidth for frequency UP-DOW N to
25 kHz. The following command has the same effect:
FREQuency:STEP 25 kHz
Note: An opt ion al k ey w or d m us t not b e o m itted if its effect is s pec ifi ed
in detail by a numeric suffix.
Long and shor t form: The keywords c an be of a long f orm or a short form . Either the short f orm
or the long form can be entered, other abbreviations are not permissible.
Example: Long form: STATus:QUEStionable: ENABle 1
Short form: STAT:QUES:ENAB 1

4052.2000.02 4.6 E-7
Note: T he short form is marked by upper -case letters, the long form
corresponds to the complete wor d. Upper-case and lower -case
notation only serve the above purpose, the device itself does
not make any difference between upper- and lower-case
letters.
Parameter: The param eter must be separated f rom the header by a "whit e space". If
several param eters are specified in a comm and, they are separated b y a
comma ",". A few queries perm it the param eters MINim um, MAXim um and
DEFault to be entered. For a des cript ion of the t ypes o f par ameter, r efer to
"Parameters" on page 9.
Example:
SENSe:FREQuency? MAXimum Response: 3000000000
This query requests the maximal value for the input frequency.
Numeric suffix: If a device f eatures several functions or characteristics of the sam e kind,
the desired function c an be selected by a suffix added to the command.
Entries without suffix are interpreted like entries with the suffix 1.

4052.2000.02 4.7 E-7
4.4.3 Structure of a command line
Several commands in a line are separated by a semicolon ";". If the next command belongs to a
different command system, the semicolon is followed by a colon.
Example:
SENSe:FREQuency:STARt MINimum;:OUTPut:FILTer:LPAS:STATe ON
This command line contains two commands. The first command is part of the SENSe
system and is used to specif y the start frequenc y of a scan. The second comm and is part
of the OUTPut system and sets the AF filter.
If the successive com mands belong to the sam e system, having one or sever al levels in comm on, the
command line can be abbreviated. To this end, the se c ond c om mand after the semicolon s tarts with th e
level that lies below th e common levels (see also Fig. 4-1). T he colon following t he semicolon m ust be
omitted in this case.
Example:
SENSe:FREQuency:MODE CW;:SENSe:FREQuency:FIXed:AFC ON
This command line is repr esented in its full len gth and contains t wo commands separ ated
from each other by the semicolon. Both commands are part of the SOURce command
system, subsystem FREQuency, ie they have two common levels.
When abbreviating the command line, the second c ommand begins with the leve l below
SENSe:FREQuency. The colon after the semicolon is omitted.
The abbreviated form of the command line reads as follows:
SENSe:FREQuency
:MODE CW;FIXed:AFC ON
However, a new command line always begins with the complete path.
Example: SENSe:FREQuency:MODE CW
SENSe:FREQuency:FIXed:AFC ON

4052.2000.02 4.8 E-7
4.4.4 Responses to queries
A query is defined for each setting command unless explicitly specified otherwise. It is formed by adding
a question mark to the associated set ting command. According to SCPI, t he responses to q ueries are
partly subject to stricter rules than in standard IEEE 488.2.
1 The requested parameter is transmitted without header.
Example: SENSe:FREQuency:MODe Response: SWE
2. Maximum valu es, minimum va lues and all f urther quantities, which are reques ted via a specia l text
parameter are returned as numerical values.
Example: FREQuency? MAX Response: 3000000000
3. Numerical values are output without a unit. Physical quantities are referred to the basic units.
Example: FREQuency? Response: 100000000 for 100 MHz
4. Truth values <Boolean values> are returned as 0 (for OFF) and 1 (for ON).
Example: OUTPut:FILTer:STATe? Response: 1
5. Text (character data) is returned in a short form (see also "Parameters" on page 9).
Example: SENSe:FREQuency:MODe?
Response: SWE

4052.2000.02 4.9 E-7
4.4.5 Parameters
Most commands require a parameter to be specified. The parameters must be separated from the
header by a "white space". Permissible parameters are numerical values, Boolean parameters, text,
character strings, block data and expressions. The type of parameter required for the respective
command and the permissible range of values are specified in the command description (see
"Description of commands" on page 13).
Numerical values Numerical values can be entered in any for m, i.e. with sign, decim al point and
exponent. Values exceeding the resolution of the device are rounded up or
down. The mantissa m ay comprise up to 41 charac ters, the exponent m ust lie
inside the value r ange -999 to 999. The expon ent is introduced by an "E" or
"e". Entry of the exponent alone is not permissible. In the case of physical
quantities, the unit can be entered. Permissible units are as follows:
for frequencies GHz, MHz or MAHz, kHz and Hz, default unit is Hz
for times s, ms,
µs, ns; default unit is s
for levels dBuV; default unit is dBuV
for percentage PCT, default unit PCT
If the unit is missing, the default unit is used.
Example:
SENSe:FREQuency 123 MHz = SENSe:FREQuency 123E6
Special numerical The texts MINimum, MAXimum, UP, DOWN and INFinity are interpreted as
special numerical values.
In the case of a query, the numerical value is provided.
Example: Setting command: SENSe:GCONtrol MAXimum
Query: SENSe:GCONtrol Response: 100
MIN/MAX MINimum and MAXimum denote the minimum and maximum value.
UP/DOWN UP, DOWN incr eases or reduces the numerical value by one step. The s tep
width can be specified f or some parameter which can be set via UP, DOW N
via an allocated step co mmand (see Annex C) . Some parameters can only be
changed in fixed steps ( eg SENSe:BWIDth UP).
Page 84
EB200 Manual Remote control
4052.2000.02 4.10 E-7
INF INFinity stands for +
∞. For queries the num erical value 9,9E37 is outp ut.
With MSCAN, FSCAN or D SCA N, th e INF v alu e 9, 9E 3 7 is e ntere d i n t he r es u lt
buffers
MTRACE and ITRACE to mark the end of range.
NINF Negative INFinity (NINF) stands for - ∞. For queries the num erical value
-9,9E37 is output. In a m easured v alue quer y, this value wil l be output if owin g
to the device setting the measurement cannot be carried out.
NAN Not A Number (NAN) stands for the value 9,91E37. NAN is only sent as a
device response. This va lue is not define d. Possible c auses are the div ision of
zero by zero, the subtraction of infinity from infinit y and the display of missing
values (eg with TRACe[:DATA]?).
Boolean parameters Boolean parameters represent two states. The ON state (logically true) is
represented by ON or a nu meric al value unequa l to 0. T he OFF state (lo gically
untrue) is represented by OFF or the numerical v alue 0. 0 or 1 is provide d in a
query.
Example: Setting command:
OUTPut:FILTer:STATe ON
Query: OUTput:FILTER:STATe?
Response: 1
Text Text parameters (character dat a) observe the s yntactic rules for k eywords, i.e.
they can be entered usin g t he s hor t or lon g form. Like any param eter , they have
to be separated from the header by a "whit e space ". In the cas e of a qu ery, the
short form of the text is provided.
Example: Setting command: SENSe:FREQuency:MODE FIXed
Query: SENSe:FREQuency:MODE?
Response FIX
Strings Strings must always be entered in quotation marks (’ or ").
Example: SYSTem:SECurity: OPTion "123ABC"
or
SYSTem:LANGuage ’English’

EB200 Manual Remote control
4052.2000.02 4.11 E-7
Block data Block data (Definite Length Bloc k) are a transmission format which is s uitable
for the transmission of large amounts of data. A command using a block data
parameter has the following structure:
Example: HEADer:HEADer #45168xxxxxxxx
ASCII character # introduces the data block. The next number indicates how
many of the following digits describe the length of the data block. In the
example the 4 following digits indicate the length to be 5168 bytes. The data
bytes follow. During the tr a nsmission of these data bytes all E nd or other control
signs are ignored until al l b ytes are tr a ns mitted. Data elements compr ising more
than one byte are transmitted with th e byte being the first which was specif ied
by SCPI command "FORMat:BORDer".
Expressions Expressions must al ways be in brackets. The devic e requires this data for mat
for the indication of channel lists. A channel list always starts with @ followed by
a path name or channel numbers or ranges of channel numbers.
Example: ROUTe:CLOSe (@23)

4.5 Description of commands
Note: For overview of commands see tables in Annex C.
4.5.1 Notation
In the following secti ons, al l comm ands implem ented in the device are describ ed in de tail. The n otation
corresponds to a lar ge extent to that of the SC PI standards. The SC PI conformity inform ation can be
taken from the list of commands in Annex C.
Indentations The different levels of the SCPI c omm and hier arch y are repres ented i n the
description by means of indentations to the right. The lower the level is, the
further is the indentation to the right. Please observe that the complete
notation of the command always includes the higher levels as well.
Example: SENSe:FREQuency:MODE is indicated in the description as follows:
SENSe firs t level
. :FREQuency second level
. . :MODE third level
Upper-/lower-case notation
Upper/lower-case let ters serve to mark the long or short f orm of the key
words of a command in the desc r ipti on (s ee nex t sec t i on) . T he dev ic e itse lf
does not distinguish between upper- and lower-case letters.

Special characters | A selection of keywords with an identic a l ef f ec t ex is ts for s om e c ommands.
These keywords are given in the s am e line and are separ ated b y a vertica l
stroke. Only one of these k eywords has to be indicated in the header of
the command. The effect of the command is indepe ndent of the ke ywords
being indicated.
Example: SENSe
:FREQuency
:CW|:FIXed
The two following comm ands of identic al meaning can be formed. T he y set
the frequency of the device to 123 MHz:
SENSe:FREQuency:CW 123E6 = SENSe:FREQuency:FIXed 123E6
A vertical strok e in ind icati ng the param eters m arks alter native pos si bilit ies
in the sense of "or". The effect of the command is different, depending o n
which parameter is entered.
Example: Selection of parameter for command
SENSe:GCONTrol:MODE FIXed
MGC AUTO AGC
If the parameter FIXed is selected, the gai n is determ ined by
the MGC voltage. In case of AUTO the gain depends on the
signal.
The two parameters MGC and AGC are synon ymous f or FIXed
and AUTO.
[ ] Keywords in square brackets c an be omitted in the he ader (see "Comm on
commands" on page 15). The device has to accept the full command
length due to reason of compatibility to SCPI standard.
Parameters in square brackets can also be optionally inserted into the
command or can be omitted.
{ } Parameters in braces can be inserted in the command either with the
options not at all, once or several times.
