Operation preparation UMS100/120/120 System Manual

1 Operation preparation

1.1 Foreword

This manual describes the interconnection of one or more UMS100/120 with a control PC to a high­capacity, extensively automatic radio monitoring network.

In addition, steps are described required for setting-up measurements which run automatically on the
UMS100/120.

The system operator is then only required if a UMS100/120 detects a deviation and has triggered an
alarm on the control PC in the main office. Manual tests must then be performed interactively to obtain
further information. This procedure is also outlined as an example.

UMS100/120/120 System Manual Operation preparation

1.2 Installation/preparation

The UMS100/120 components and control PC are also referred to as network elements in the following,
in accordance with ARGUS nomenclature. Before the actual configuration of these network elements
(UMS100/120 and control PC) can begin, the type of connection must be determined. Therefore it is
strongly recommended to enter the names, IP addresses, modem telephone numbers and other access
parameters such as user names and passwords, etc into a corresponding table. Only then can the
configuration of the network elements take place smoothly and enable communication.

Allocating IP addresses is essential for the network elements to be able to communicate clearly in the
network.

The definition of IP addresses in the private address range will not be discussed here in any detail.
There are explanations in the corresponding literature (e.g. using the Internet at Wikipedia:
http://de.wikipedia.org/wiki/Hauptseite or according to RFC 1918, go directly to
http://www.ietf.org/rfc/rfc1918.txt).

If more than one UMS100/120 is operating in the network, the configuration must take place before it is
connected to the network (LAN/WAN), as all UMS100/120 are set with a factory default address
(192.168.0.31).

One such configuration table is attached in appendix A which is filled in with several stations and the
accompanying parameters as an example.

This or the UMS100/120 to be connected is/are to be installed and connected to the power supply in
accordance with the "Mechanical Installation Manual". In the case of a LAN/WAN connection, the
UMS100/120 must be configured before with regards to the address.

The main office must be accessible at all times and supplied with the appropriate equipment for set-up
and operating a standard PC with keyboard, mouse and a printer.

Depending on the type of UMS100/120 connection, suitable telecommunication lines must be available.
This includes LAN/WAN access and/or analogue telephone lines for at least one, but usually two
modems. GSM module as modem can also be used alternatively. In this way the main office also has a
"wireless" connection.

A standard PC is suitable as a control PC equipped with a Pentium IV processor, 512 MB memory, at
least 40 GB hard drive, CD or DVD-RW drive and an adequate number of RS232 ports (for external
modems) or PCI card slots (for internal modems). At least one free USB connector must be available
for the USB hardlock.

Operation preparation UMS100/120/120 System Manual

Figure 1-2: UMS100/120 connection to the main office (via LAN/WAN (red) or mobile network (blue))

When using a LAN/WAN connection via e.g. SHDSL connections, that are available in many countries
now as point-to-point connections should be completely end-to-end tested by the telephone network
operator, including modems.

1.3 Web-based Service Tool in UMS100/120

To carry out the minimal service work when up and running and for the initial configuration, a user
interface can be used which is web-based and can be started on each UMS100/120. A web browser
such as MS Internet Explorer from version 5.0 (better 6.0) can be used or e.g. Mozilla Firefox 1.4 on
any control or service PC. The control or service PC is connected to the system that has to to be
configured via a LAN/WAN or mobile network connection. Once the IP address has been entered the
configuration tool starts up. The user interface of the configuration tool is only available in English.

Furthermore, a service PC does not require any other special programs.

UMS100/120/120 System Manual Operation preparation

1.4 UMS100/120 configuration for LAN/WAN
connections

CAUTION

The configuration must take place before installing the device within the LAN as they all
have the same IP address (192.168.0.31) from the factory by default. Without previous
configuration, the devices would not be able to communicate individually in the network and
there would be an IP address conflict.

The configuration is either done in a central delivery store before they are distributed to the site or it is
done by a technician on site after the mechanical installation using a service notebook.

A standard PC with a LAN interface and a web browser (e.g. MS Internet Explorer, see chapter 1.3) is
required for the configuration.

Connect the PC to the UMS100/120 in one of the two following ways:

Connect the RJ45 socket on the PC to the corresponding socket on the bottom of the UMS100/120

•

to be configured directly using a cross wired LAN cable.

Connect the RJ45 socket on the PC to the corresponding socket on the bottom of the UMS100/120

•

to be configured using an uncrossed cable by interconnecting a simple LAN switch or hub.

Then start the UMS100/120 by connecting it to the power supply.

Now start up the PC and set the network card to an IP address within the address range 192.168.0.xxx,
Subnet. 255.255.255.0, e.g. 192.168.0.11. The 192.168.0.31 IP address may not be used as this is the
UMS100/120 address ( IP address conflict).

Then start up the web browser.

To open the service tool in UMS100/120, enter the following address in the browser window.

CAUTION

As this is a matter of a secure connection it is essential to enter "https:…..".

https://192.168.0.31

The following security message appears:

3030.3059.72-02.00 10

Operation preparation UMS100/120/120 System Manual

Figure 1-3: Service Tool, security certificate

As the communication between the control PC and UMS100/120 is processed in SSL (encrypted /
secure sockets layer), the UMS100/120 provides a certificate. A warning always appears to inform that
the name does not match the name of the site (see Figure 1-3). Acknowledge this certificate by clicking
on <Yes>.

UMS120 incorporates the modular version of the UMS100 complete system. Users therefore can
connect to the UMS120 a large range of monitoring antennas from Rohde & Schwarz (transducers are
interpreted) as well as from other suppliers (transducers are not interpreted) and configure these within
the service tool.
The displayed pages of the service tool are slightly different to UMS100 having an additional menu
entry for antenna configuration with UMS120 (refer to Figure 1-7).

Operation preparation UMS100/120/120 System Manual

Figure 1-12: Options for UMS120

CAUTION

Options installed in UMS120 only control the settable frequency range.

Antenna Configuration (only UMS120)

Two different antennas can be connected to the UMS120 out of the portfolio of R&S monitoring
antennas (or from other suppliers) having corresponding or also slightly overlapping frequency ranges.
After selection in the service tool the corresponding transducer tables and connection cable types and
lengths are considered in the ARGUS control SW. Through this correct field strength levels can be
displayed.

In case of overlapping frequency ranges of the antennas the Transition Frequency can be calculated
from the tool (mid of overlapping range) or can be set manually by entering the value manually into the
appropriate input field if this is preferred.
Further the used cable types and lengths and – by use of active antennas – the necessary DC-feeds
can be selected. Clicking the <Update> button shows the antenna parameters.

After clicking on <Submit> the selected settings are activated on the UMS120.

CAUTION

In case that a combination between “no antenna” and “unknown antenna dBm” or
“unknown antenna dBMV” is selected, the ARGUS control SW only displays voltage levels
in dBm or dBMV.
A combination of “unknown antenna” and known (R&S) antenna nevertheless only displays

voltage levels. (Transducer tables from other antenna suppliers can not be entered.)

Now the UMS100/120 has been set so that it can be installed on the network and connected to the
ARGUS-UMS (or ARGUS) control program.
Finally open the page Logout and click on <Logout>. Wait until the login window appears and close the

Operation preparation UMS100/120/120 System Manual

1.5 UMS100/120 configuration for dial-up
connections using a mobile network

CAUTION

Before the UMS100/120s can be connected via a mobile phone network to, for example,
GSM technology, "SIM cards" must be obtained from that network operator which provides
sufficient coverage at the planned UMS100/120 locations. In addition, UMS100/120
operator must apply for a special number for the Data Call function with the "SIM card".
Before insertion of the “SIM card” into the UMS100/120 the “PIN entry” must be disabled.

This can be done by placing the card into a standard mobile phone.

Insert the SIM card prior to starting the UMS100/120. The UMS100/120 must be disconnected from the
power supply. For further information please refer to the UMS100/120 User Manual.

It is now possible to carry out full configuration via the GSM connection which is available once the SIM
card has been inserted and the power supply is connected up. But further preparation is necessary on
the control PC for setting up dial-up networking which will be described in due course.

Due to the high speed, we recommend that the UMS100/120 configurations are done using the LAN
interface, as previously described.

The procedure is the same as the one already described (Figure 1-3 to Figure 1-9). In addition, you
must also fill in the parameters for Incoming Connection and Dialup Connection for the reverse
direction in the last entry field (Figure 1-10) and click on <Submit> each time to send it to the
UMS100/120.

1.6 Configuring the control PC for a LAN/WAN
connection

When all the UMS100/120 are connected by LAN to the control PC in the main office, make sure the
network card address is set as follows:

The address must be located in the same address range as all the UMS100/120.

•

The Subnet Mask must also correspond.

•

If a router is being used in the network to connect different addresses, set its address as Default

•

Gateway.

1.7 Configuring the control PC for a GSM connection

Diagrams of the configuration window and the corresponding descriptions are based on Microsoft
Windows XP professional operating system. The configuration in MS Windows 2000 varies slightly in
different places. However, basically the specific settings can be made in the same way.

For the following configuration it is assumed that at least one, but preferably two modems are set up on
the control PC and connected to the phone lines.

For two or more modems, you can use one for the outgoing connections to the UMS100/120 if the
operator is actively connected. Any other modems can then be available to receive UMS100/120

2.2 Connecting to a UMS100/120

There can be several connections to UMS100/120 in a LAN/WAN network. For dial-up networking, this
is restricted to the number of previous modems for outgoing connections.

However, you can only activate one connection from ARGUS. An active connection is necessary to
perform direct measurements (DMMs) or define automatic measurements (AMMs). If you need to
activate another connection it will be declined if there are any control windows still open. Otherwise an
activated connection will be disconnected.

Therefore the Select window contains the buttons <Connect> as well as <Connect and Activate>.

Depending on the type of connection, setting up the UMS100/120 connection takes up to one minute.
During this time a corresponding window appears. For dial-up networking the RAS States (2  4  5
 10-> DUN connected) are displayed via the Connection Set Up Status.

If a connection to a UMS100/120 is set up for the first time, the configuration is not available on the
control PC. Therefore, a window appears while the system is setting up the connection and informs you
of a "mismatch" in the configuration. Then the configuration is automatically loaded. The reception
procedure can take up to one minute for slower connections. Once the transfer is successfully
completed, press <OK> to quit.

DMM

The window of the manual operation, also called "Direct Measurement Mode" DMM is directly opened
after closing Select UMS window or using the menu command of the same name under Measurement

r directly using <F4>.

o
If frequency extensions are activated, it is shown next to the UMS100/120 name, e.g. UMS100

100.000 KHz – 6.000000000 GHz..

The menu item View  Antenna opens the ANTENNA window for more information.

Figure 2-5: Antenna information

The DMM control window for UMS100/120 offers three types of measurements:

Fixed Frequency Mode - FFM: single frequency measurement, level, frequency, offset

•

Scan with start and stop frequency input and increments for a quick overview.

•

Frequency List Scan - FLS: single frequency measurement for preset frequency lists

•

For all of these measurements a detector (FM, AM) and listening to demodulated audio signals on the
control PC can be selected.

All levels will be displayed with UMS100 in dBMV/m (field strength) and with UMS120 depending on the
antenna configuration also in dBm/dBMV (voltage).
Depending on the bandwidth of the UMS100/120 connection, you can select a suitable Audio Transfer

Rate (in kbit/s) with more or less audio signal compression.

CAUTION

In case of GSM connections only the two lowest Audio Transfer Rates may be used.
Higher rates also block the transfer of measurement values leading to "timeouts" in the
communication and disturbances to the connection.

2.3.1 Gain Control

The available settings for Gain Control allow an attenuation of the input signal up to -30 dB as well as
an amplification of up to +25 dB to adapt the UMS100/120 to various measurement activities.

For an automatic adoption (AGC) it is possible to select

Fast (1 ms)

•

Medium (10 ms, only in FFM) and

•

Slow (100 ms, only in FFM)

•

2.3.2 Overload Indicator

For all manual measurements an overload indicator is available.

In case that the antenna input level reaches a critical value, where the pre-amplifier could produce
intermodulation or more critical, the analogue-digital-converter could be overdriven, the indicator color is
changing from green as shown above to red.

CAUTION

Performing a wide frequency scan (see next chapter) beginning with 100 kHz, step width of
20 MHz and wide IF bandwidth of 1 MHz the following effect can be seen:
In the area of the start frequency (100 KHz) the frequency of the local oscillator is within the
IF bandwidth of 1 MHz so that as a result a very strong level of about 130 dBMV/m is

displayed. Even with a selected attenuation of -30 dB the overload indicator will be still on.

This is a normal effect that can be observed with every receiver with corresponding

settings.

2.3.3 Getting an overview of the spectrum using Scan

For a quick look at the frequency spectrum, such as after an alarm, use the <Scan> function. Select the
start and stop frequency according to the areas of interest. The increments (step width) are oriented to
various criteria.

he smaller the increment, the slower is the scan. Alternatively, in the display there are small

T
increments for a higher resolution. In this way, signals can be detected that are very close to one
another. However, this can be restricted by the resolution of the screen you are using. Generally, the
ratio between the selected IF bandwidth and the increment is important. However, you can overlook this
ratio, as the Detector is generally in a max. peak position. Each signal is then displayed, even within
larger increments. The strongest signal determines the level value of the increment.

Here you are asked to develop suitable parameters for the signals which are of particular interest to
you.

Some examples for various parametrizing, for a better visualization of the time sequence with switched
on 2D waterfall diagram (for further information please refer to chapter 2.3.4):

If an interesting signal (peak) is found in the spectrum, depending on the step width, another scan may
be necessary over a more limited frequency range with smaller steps.

2.3.4 Waterfall Diagram in Scan Mode

The examples in chapter 2.3.3 show also the 2D Waterfall Diagram. Here the signals were shown in
the time sequence. Thus clear information is available about the duration and how often a signal is
transmitted.
The relevant level however can only be classified according to the displayed color.

2.3.5 Max Hold in Scan Mode

The red enveloping line shows the strongest signals that have been appeared since Max Hold has

een switched on. Here also signals with a short period are displayed with their peak level as it is in

b
voice radio transmissions. Also signals with fluctuating levels are recognized with their max. peaks. The
peaks can be selected with the marker where exact marker frequency and level is shown in the line
above the scan graphic.

Figure 2-8: Scan with Max Hold

2.3.6 Listen Mode in Scan

Before starting the scan, a suitable Demodulation (AM/FM), IF Bandwidth, Audio On, Audio Transf.
Rate and Volume should have been selected.

During a running scan a double click on the signal peak stops the scan, sets the marker on that position
and the audio modulation of the signal can be heard. The following Figure 2-9 shows the listening at
439,25 MHz. If the scan shall be restarted, the listen symbol (clef) has to be clicked once. To stop click
on the listen symbol again.

If the Listen Mode is activated the marker can also be moved with the mouse (or the cursor buttons
left and right) to other peaks.

2.3.7 Bandwidth Measurement in Scan

Before starting the Bandwidth Measurement the Start and Stop Frequency should be set so that the
range is at least about two times wider than the expected bandwidth (test-scan). The Bandwidth
Measurement can only be selected with button <B> if the scan is stopped.
There are two possibilities:

x dB down (default is 26 dB)

•

Percent below peak (ß measurement) (default 1 %)

•

Please insure before starting the measurement that a sufficient measurement dynamic range is
available (e.g. S 30 dB).The measurement is always performed with Max Peak. Also the step width
should be made small enough to get a fine resolution.

After starting the scan the center frequency marker is manually set with the mouse or by entering

•

the frequency in the corresponding input field.

The measurement window is set in that way that one of the yellow lines is moved with the mouse

•

where the other follows symmetrically around the center. Another method would be to enter the
value in the corresponding input field.

Depending on the selected number of scans (1, 10, 100) and sufficient measurement dynamic the

•

differential markers appear on the screen (small yellow circles at the left and right flanges of the
signal of interest) and the corresponding calculated bandwidth is displayed in the line above the
graphic.

The following picture shows the ß-method with 1 % setting.

Operating with ARGUS-UMS UMS100/120/120 System Manual

Figure 2-12: Frequency measurement in FFM

CAUTION

System based, only carriers or amplitude modulated carriers can be measured exactly. For
frequency modulated carriers there is no center frequency displayed but a frequency within
the bandwidth of the signal. Depending on modulation deviation of the FM signal the Offset
fluctuates, i.e. the difference between to the set frequency can be up to some kHz.

The above example (Figure 2-12) shows the frequency of a narrow-band FM signal where a
measurement is realistic for such kind of transmitters.
The accuracy can be evaluated by watching the differences over a period of some seconds. If the
differences are only some Hz the result can be trusted.

The measurement window (here 100.000 kHz) should not be made too large. Otherwise, another
signals with a higher level also located in this window, might be displayed instead.

The next figure shows an example of measuring an AM transmitter. The frequency is exactly coupled
with a normal frequency source.

2.4 Definition of automatic measurements (AMM)

To a large extent automatic measurements will be the main kind of operation, as in a network of
different UMS100/120, so the operator is released from routine activities an can concentrate on other
activities.

During a short online session with the UMS100/120 the required settings are defined. Then the
connection can be disconnected and the UMS100/120 carry out the measurements “offline”
continuously.

When AMM is selected for the first time the following window appears:

Figure 2-14: Preconditions for AMM

To start the automatic measurement, the Range Definition, Measurement Definition and Timing
Definition have to be defined. Each of these definitions can be available several times and be assigned
for a specific automatic measurement with additional adaptations. During operation, a large set of
different definitions are then available for the operator's various measurement requirements.

Note:
Before an automatic measurement is defined and started, first run a test with specific settings in the
manual measurement mode. There is a range of combinations which exclude one another. In addition,
there are limits for measurement times, bandwidths and automatic settings resulting in different
parameters.

If automatic measurements are started with parameters that do not match, you possibly will not receive
an error message straight away but only later in the log file.

2.4.1 Memory required for different measurements and
audio recordings

The following table gives the user a roughly overview of the memory required for different
measurements. From these durations an AMM planning could be derived.

2.4.2 Creating automatic measurements with AMM Wizard

By use of the AMM wizard an automatic measurement can easily be set up in 5 steps. This procedure is
recommended especially for unskilled beginners.

Begin by accessing the AMM menu, go to Extras  AMM Wizard ... and open the first mask.

Figure 2-15: Accessing AMM Wizard

3030.3059.72-02.00 46

Operating with ARGUS-UMS UMS100/120/120 System Manual

Step 1:

The first step (Step 1) defines the timing. To keep things flexible, almost all variants of any and
repeated measurements are possible.

In the following example, two periods on Tuesday at 9 o'clock for 6 hours are defined.

•

However, for continuous monitoring activities with UMS100/120, select Measurement is always

•

performed, that is "round the clock" 365 days of the year (first selection).

The last point is of interest if measurement data is recorded over a longer time period and for

•

example, measurements are carried out only every 15 minutes so as to save memory space.

Note:
The total available memory space is not the issue here. As a rule, the memory is sufficient for
measurements taking several weeks. More importantly, the recorded measurement values must be
transferred so they can be analysed by the operator. The transmission can take a long time, particularly
for large amounts of data when using a slow GSM connection. Please refer to the notes in the previous
chapter.

and Stop Frequency. If "narrow band" signals i.e. with an IF bandwidth corresponding to the type
signal shall be monitored, the Step Width is usually adjusted to the channel spacing of the radio
service in that frequency range.

Do not follow this rule in case that high scan speeds over large frequency ranges should be

achieved. Here increments of up to 20 MHz with IF setting of 1 MHz should be selected.

Even for an IF bandwidth of max. 1 MHz no signal will be lost, also not with narrow band carriers.

Step 3:

In Step 3 the measurement settings are selected.

If stronger signals are expected, select -20 dB or even -30 dB at Gain Control.

•

For very weak signals select the +25 dB setting.
In case of frequently changing signal levels the Automatic Gain Control (Fast, i.e. with FFM also
Medium/Slow) may be the preferred choice.

Keep the measurement period for scans as short as possible, select ≤ 1 ms for fast scans.

•

Demodulation is not important during a scan.

•

For fixed frequency measurements also Frequency and Offset can be selected or - alternatively

•

Audio. In this case the demodulated audio signal will be directly recorded on the UMS100/120. For
this purpose a demodulator must be switched on which is not possible at this point. Please refer to
chapter 2.4.3.

If there is an active connection to the UMS100/120 during AMM, the continuous measurements can

•

then be shown in the form of a graph. You can select the graphic type here.

as if and how an alarm is to be triggered automatically at the Control PC. in the center. The <Alarm>
button opens a window for this purpose. Here the essential things are now defined for automatic
operation.

If measurement results are to be saved on the UMS100/120 the Measurement Time preset must

•

be taken into account. A continuously running measurement creates huge amounts of data and the
memory runs at full capacity. Besides fast scans, this can occur particularly when there are
continuous audio recordings (see Section 2.4.1).

What may be more important is that the large amounts of recorded data must also be “moved” from
UMS100/120 to the Control PC using an extremely slow interface. For example, a limited audio
recording with RF level takes at least approx. one minute to transfer, even with a fast LAN
connection. Using a GSM connection a transfer would take approx. 6 hours.

If a continuous measurement with automatic alarm is to be performed, the Measurement Result

•

during an Alarm or Begin and End of an Alarm settings are sufficient. There are various options
for configuring the alarm criteria in the Alarm window.

One option is to enter the highest limit value as a fixed line via the scan range. This variant runs

•

ell if there is no other carrier apart from the transmissions expected. If the level is exceeded by a

w
signal, the alarm criterion is fulfilled. The actions selected at Alarm Actions are carried out, such
as starting a second measurement which e.g. measures the alarm frequency exactly.

The Message function and a Signal Tone are only released on the Control PC if there is an active

•

connection.

In case SMS is selected and a mobile phone number with information text has been entered, the

•

UMS100/120 sends a short message to this mobile phone if an alarm occurs. The only condition is
that a SIM card has been inserted. Please follow the instructions in chapter 1.5.
The SMS alarming is send only once after an initialization of the alarm. New SMS will only be sent
after restart of the AMM or after the first new alarm following midnight (00:00 h).

Another option is to measure against a predefined Limit Line. To do this, a spectrum is saved

•

during a DMM as the actual status with any Offset of ± x dB. If a new signal is detected, it is
recognized by an Overshoot measurement. If a carrier fails, it is recognized by an Undershoot
measurement. In Section 2.4.4 the setting for the Limit Line is described.

Step 5:

In Step 5 proposals are made for the names of the three files to be created which can be accepted or
overwritten. Click on <Finish> to end the definition.
The following question if the settings should be stored as presets can be answered at discretion.

2.4.3 Other AMM settings

To obtain other settings the AMM window can be enlarged by clicking on <Settings>.

Forward Messages is switched on in the Messages area for the automatic alarming.

•

At the Station input field, the name Control Unit is always shown in ARGUS-UMS.

•

The Delay Time determines a delay after the first alarm has been detected before the UMS100/120

•

connects to the control PC automatically. This delay is very important particularly with a GSM
connection. The value should not be set at too short intervals so as to avoid frequent connections. If
continuous alarms are expected, do not set the time at less than one minute intervals. Otherwise,
there is a danger that AMM can not be stopped due to a blocked outgoing connection coming up
against a frequently occupied UMS100/120 because this is permanently sending alarms.

The setting Summarize Messages controls if alarms that are displayed in the General Log File

•

have only information about date and time of alarm or detailed information about the kind of alarm
with e.g. frequency, level etc..

2.4.4 Creating limit lines

In the actual measurement mode, a scan is started for the required frequency range and then

•

stopped when the display result is satisfactory. This shall form the “as it is” status of the spectrum.

In the scan window click the button <Create Limit Line> (disk symbol with green scan curve on top).

•

The Navigator window opens for entering a name. Click <New> to close the window.

Figure 2-26: Creating a Limit Line from the Scan graph

Enter an Offset for the measured spectrum in the Create Limit Line window that follows.

Set the appropriate Offset. Positive or negative offset depends on whether the alarm goes off when

•

the Limit Line is later overshoot or undershoot in the automatic measurement.

A positive offset of 5 dB for example, pushes the limit up. Slight level fluctuations do not trigger the

•

alarm with the Overshoot setting; however it will be triggered if there is a new, stronger and
unknown signal.

If a signal is too weak and is under the limit with the Undershoot setting or disappears completely,

•

the alarm will then be triggered.

In case that previously Max Hold was switched on also the Max Hold line can be saved as limit line.

•

If Max Hold was running some time before saving, smaller fluctuations in signals are recorded and
as an effect out of this, for Overshoots the Offset can be set to smaller values.

Figure 2-27: Offset setting for the Limit Line

Click <OK> to quit.

The Limit Line can now be selected during the definition of AMM.

2.4.5 Creating frequency lists

Sometimes it makes more sense not to scan a wide frequency range but just some individual
frequencies. These are put into a frequency list.

In Navigator, select File Type  Frequency List.

•

Enter a new „name“.

•

Click on <OK> to close the window. Now a blank frequency list opens.

•

Enter the frequencies you want to scan. After closing the list, it directly can be used for measuring.

•

Figure 2-28: Creating a frequency list

Instead of entering manually, you can also import a frequency list created in Microsoft Excel. Go to File
 Import  Frequency List.

Another possibility exists by takeover certain frequencies out of the scan graphic in DMM.
Firstly open an existing or new frequency list in the Navigator. Now the Scan Mode is started in DMM.
If the spectrum has been measured, certain frequencies can be selected with the marker. By clicking on

the symbol the frequency is taken over in to the Frequency List.

2.5 Analyzing alarms and measurement results

In conclusion with an alarm warning or after an AMM has been stopped the measurement results have
to be evaluated.
Before, it may have happened that under certain circumstances with special measurements including
audio recording the available disk space came to a minimum of less than 5 %. In this situation the
following alarm appears in the General Log File:

Figure 2-30: Disk capacity shortage on UMS100/120

Now the following tasks should be done:

Make a connection to the relevant UMS100/120 if there is not one already.

•

Open the Navigator and select the Remote Measurement Files tab. All the measurement results

•

and log files are displayed here that are saved in the remote UMS100/120.

Mark the files by clicking on them. Several or all of them can be selected simultaneously. Selection

•

of single files allows displaying the file size. Go to File Attributes to view the relevant information.
More detailed information is available on Measurement Results Files by clicking <File Info>
(please refer to Figure 2-32).

Click on <Move> to transfer the marked files to the control PC.

•

Figure 2-33: File transfer to the Control PC

Once the transfer is complete, the files are deleted on the UMS100/120, thus making more memory
available.

Should you inadvertently copy very large files (particularly audio) which cannot be transferred within an
acceptable time due to a slower GSM connection, click on <Delete> to erase the files directly.

After transferring, the files are located on the control PC under System Files. You can open the files as
text or as a graph and export them to another program for processing, if required. Click <Replay..> to
playback audio recordings. You can also save the files as Backup Files.

2.6 ORM_ADC interface to other SW user interfaces

Some monitoring system users already have a customized user interface geared to their specific
purposes which it is essential to keep. For these situations there is a fitting solution by using O

eport Module with ARGUS Data Channel. This is available on the control PC for the remote control of

R

all the UMS100/120 connected up in the network. Simple commands are transferred in XML files to an
input folder in the control PC via LAN and then processed by the system. The results are then put into
an output folder ready for collection. You can forward live measurement results to the higher level
system by “UDP data stream” and then the data is displayed in the external application.

A detailed description of the ORM_ADC interface is provided in a special document.

3 Maintenance

3.1 Firmware update

Sometimes it is necessary to update the Firmware in the UMS100/120. Open the function in the
Service Tool which is started by the web browser and entering the specific IP address.

The Firmware is either provided by Rohde & Schwarz Service on a CD or in some cases it can be
downloaded from the following Internet address:

http://www.ums.rohde-schwarz.com

CAUTION

In many cases, it is necessary to update the version of the control software on the control
PC before a Firmware update on the UMS100/120 is performed; otherwise operation is no
longer possible.

Before the Firmware update, clarify with each UMS100/120 whether it is compatible with
the relevant ARGUS-UMS version or whether a Service Pack must be obtained.

The update must be performed via a LAN/WAN interface as the entire Firmware is always transferred
(currently approx. 23.5 MB). Updating a UMS100/120 via GSM is actually not possible, because this
involves a downloading period of almost eight hours but the Service Tool is already shut down after 30
minutes for safety reasons.

3.2 Cleaning the hard drive and restarting

UMS100/120

In rare cases, the memory needed for the measurement data is not properly released. The
UMS100/120 then is sending an alarm message via the general Log File informing the operator that

nly a small percentage of the memory is available. If moving or deletion of measurement files is not

o
successful and the message still appears, it might be necessary to perform a memory cleanup.
Open the Service Tool. Go to Maintenance and click on <Execute> that comes after Cleanup Data

Area.

CAUTION

If Clean up Data Area has been executed, all saved measurement results on the
UMS100/120 are lost.

If the problem has not been rectified after that, a restart is recommended.

To restart, click <Execute> that comes after Restart UMS100/120.

•

Confirm the following question. The UMS100/120 is then not available for a several minutes while it

•

shuts down and restarts.

CAUTION

If a connection is made again from ARGUS-UMS, you may receive a warning that there is a
Mismatch in the configuration of the control and measurement unit. This is normal and you
can receive the configuration by clicking on <Receive…>

Appendix A UMS100 System Ma nual

Appendix A

System/network configuration table

As an example, the following table describes the configuration of a small monitoring network.
The default settings for all UMS100 are shown in the first line on a gray background. The tables describes a mixed connection of both UMS100s via LAN/WAN and via GSM mobile network. The configuration that is not required is in gray. It

is advisable to enter these settings beforehand. Otherwise, a service done locally on the LAN interface of a UMS100, connected by GSM, must still use the default IP address even though the login parameter is not default. This could be
confusing for service personnel.

Furthermore, it makes sense for any WAN connections that might be insecure to also have a parallel GSM connection (i.e. using a GSM SIM card). Therefore you have the option to reconfigure the backup connection (GMS) on the control
PC at any time.
