HAMEG instruments fulfill the regulations of the EMC directive. The
conformity test made by HAMEG is based on the actual generic- and
product standards. In cases where different limit values are applicable,
HAMEG applies the severer standard. For emission the limits for
residential, commercial and light industry are applied. Regarding the
immunity (susceptibility) the limits for industrial environment have
been used.
The measuring- and data lines of the instrument have much influence
on emission and immunity and therefore on meeting the acceptance
limits. For different applications the lines and/or cables used may
be different. For measurement operation the following hints and
conditions regarding emission and immunity should be observed:
1. Data cables
For the connection between instruments resp. their interfaces and
external devices, (computer, printer etc.) sufficiently screened cables
must be used. Without a special instruction in the manual for a reduced
cable length, the maximum cable length of a dataline must be less than
3 meters and not be used outside buildings. If an interface has several
connectors only one connector must have a connection to a cable.
Basically interconnections must have a double screening. For IEEE-bus
purposes the double screened cable HZ72 from HAMEG is suitable.
2. Signal cables
Basically test leads for signal interconnection between test point and
instrument should be as short as possible. Without instruction in the
manual for a shorter length, signal lines must be less than 3 meters
and not be used outside buildings.
Signal lines must screened (coaxial cable - RG58/U). A proper ground
connection is required. In combination with signal generators double
screened cables (RG223/U, RG214/U) must be used.
3. Influence on measuring instruments
Under the presence of strong high frequency electric or magnetic fields,
even with careful setup of the measuring equipment an influence of
such signals is unavoidable.
This will not cause damage or put the instrument out of operation. Small
deviations of the measuring value (reading) exceeding the instruments
specifications may result from such conditions in individual cases.
4. Noise immunity of spectrum analyzers
In the presence of strong electric or magnetic fields it is possible that
they may become visible together with the signal to be measured. The
methods of intrusion are many: via the mains, via the signal leads, via
control or interface leads or by direct radiation. Although the spectrum
analyzer has a metal housing there is the large CRT opening in the
front panel where it is vulnerable. Parasitic signals may, however, also
intrude into the measuring object itself and from there propagate into
the spectrum analyzer.

1.7 CAT I
This oscilloscope is destined for measurements in circuits not
connected to the mains or only indirectly. Direct measurements,
i.e. with a galvanic connection to circuits corresponding to the
categories II, III, or IV are prohibited! The measuring circuits
are considered not connected to the mains if a suitable isolation
transformer fulfilling safety class II is used. Measurements
on the mains are also possible if suitable probes like current
probes are used which fulfill the safety class II. The measurement category of such probes must be checked and observed.
The measurement categories were derived corresponding to
the distance from the power station and the transients hence to
be expected. Transients are short, very fast voltage or current
excursions which may be periodic or not.

1.6Maintenance
Before cleaning please make sure the instrument
is switched off and disconnected from all power
supplies.
Clean the outer case using a dust brush or a soft, lint-free dust
cloth at regular intervals.
No part of the instrument should be cleaned by the
use of cleaning agents (as f.e. alcohol) as they may
adversely affect the labeling, the plastic or lacquered surfaces.
The display can be cleaned using water or a glass cleaner (but
not with alcohol or other cleaning agents). Thereafter wipe the
surfaces with a dry cloth. No fluid may enter the instrument.
Do not use other cleaning agents as they may adversely affect
the labels, plastic or lacquered surfaces.
The instrument has a wide range power supply from 105 to
253 V, 50 or 60 Hz ±10%. There is hence no line voltage selector.
The line fuse is accessible on the rear panel and part of the line
input connector. Prior to exchanging a fuse, the line cord must
be pulled out. Exchange is only allowed if the fuse holder is
undamaged. It can be taken out using a screwdriver put into the
slot. The fuse can be pushed out of its holder and exchanged.
The holder with the new fuse can then be pushed back in place
against the spring. It is prohibited to ”repair“ blown fuses or to
bridge the fuse. Any damages incurred by such measures will
void the warranty.
Type of fuse:
Size 5 x 20 mm; 250V~, C; IEC 127, Bl. III;
DIN 41 662 (or DIN 41

The following chapters are intended to introduce you to the
most important functions and settings of your new HAMEG HMS

4.1 How to measure a sine wave signal
The fundamental measurement with a spectrum analyzer is
the measurement of the level and the associated frequency
of a sine wave signal. The following measurement example
demonstrates the steps to be taken for the settings which
allow to effectively perform this measurement with the HMS
series. The signal source is a hf synthesizer, e.g. the HM8135.
Connect the hf output of the synthesizer to the hf input of the
spectrum analyzer.
The analyzer displays the frequency spectrum of its full frequency
range from 100 kHz to 1.6 GHz resp. 3 GHz. At 100 MHz the generator signal will be discernible as a line. Harmonics of the oscillator
are also displayed at multiples of 100 MHz (not visible here). In
order to analyze the generator signal further, use the frequency
settings menu (key FREQ 6 ) to set the start frequency to 50 MHz
and the stop frequency to 250 MHz. The spectrum analyzer now
displays the signal with a higher resolution.
In order to determine the level of the signal, the HMS series
offers up to 8 markers. The marker is always attached to the
measuring curve. The instrument indicates the level and the
frequency at the relevant position on the screen.
Press the key MARKER 15 to enter the marker settings menu.
Marker [1] will be activated by the soft key DISPLAY, it will be
automatically positioned to the center frequency of the actual
curve. The marker frequency is indicated by a cross resp. arrow
symbol (next to the activated marker). The spectrum analyzer
displays the level and the frequency of the marker position
numerically at the top of the screen.
Now move the marker [1] to the displayed level at 100 MHz by
pressing the soft key POSITION and, after selecting the marker
(the marker indication will turn to orange), use the knob to
move it to the left; you may also enter the desired frequency of
100 MHz directly via the keyboard.
Settings on the synthesizer:
– Frequency 100 MHz
– Level –10 dBm
Press the AUTO TUNE key 18 in order to cause the instrument
to scan the whole measuring range in order to find the highest
signal peak and to display it at the screen center together with
the proper RBW and span settings. This procedure may take
several seconds.
Fig. 4.3: Level measurement with marker
4.3 Measurement of the harmonics of a sine wave
signal
Due to the property of a spectrum analyzer to resolve different
signals in the frequency range, it is well suited to measure
harmonics or the distance between harmonics and the fundamental. The HMS offers extended marker functions which allow
to arrive at a result after just a few key pressures.
Fig. 4.2: Display with the AUTO TUNE function
4.2 Level measurement
In order to now perform the previouly automatically taken steps
manually, press the key PRESET 17 which resets the instrument
to its initial settings.

Subject to change without notice
Due to the previous settings in chapter 4.2, the first marker is already located on the fundamental which should stand clearly out
of the noise floor in the lefthand screen area. The marker should
also display the selected level of –10 dBm in the upper screen
area. The first harmonic of the sine wave should now appear at
200 MHz. Depending on the purity of the signal this harmonic
may be well or hardly visible with the presently active settings.
In order to measure the distance of the first harmonic to the
fundamental proceed as follows:
Press the soft key MARKER and move the knob by one detent
position to the right in order to select a second marker (M2).
Quick introduction
Activate the marker by pressing the soft key DISPLAY. The
second marker will now appear in the center of the display.
Select the marker by pressing the soft key POSITION (the marker
indication will turn to orange) and move it with the knob (to the
right) or via the keyboard by directly entering the value 200 MHz.
Another means of spectrum analysis is the socalled video
bandwidth (VBW). This is nothing else but a low pass filter which
filters high frequency components from the signal. Using this
filter can also cause a massive increase of the sweep time, and
again a sound compromise has to be found between display
quality and measurement time.
Activate the manual VBW selection by pressing the associated
soft key and use the knob to select a 10 kHz filter from the list
in the menu which will appear.
Both levels (fundamental and harmonic) should now be well
visible on the HMS display.
4.3.2How to measure the harmonic
In chapter 4.3.1 already two markers were positioned on the
fundamental and the harmonic, the second one on the harmonic.
Open the marker menu by pressing the key MARKER 15 .
Fig. 4.4: Measurement of the harmonic of a sine wave signal
4.3.1Selection of the proper filter settings
In order to better resolve the harmonic from the noise, the RBW
and the VBW filters should be adapted to the measurement task
by using the bandwidth menu (key BANDW 9 ). The HMS series
standard procedure is to automatically set the RBW and VBW
filters such that a first approximation of a measurement of the
input signal will be possible. Manual selection of the filters will
be always superior to an automatic presetting.
The marker [2] is still selected (shown as an entry on the top
soft key) Change the active marker [2] from an “absolute”
marker to a “relative” DELTA marker by pressing the soft
key DELTA. The marker display will change from an absolute
frequency and level display to a relative frequency and level
display; the values shown refer always to the main marker
(marker [1]).
Activate the key BANDW 9 to enter the filter menu of the
spectrum analyzer. Due to the presettings, the RBW and the
VBW will be set to AUTO. Activate manual setting by pressing
the top soft key, then use the knob to select the 100 kHz filter
from the list in the menu which will appear.
The noise band displayed formerly should now be markedly
reduced such that the first harmonic will be better visible. A
further reduction of the RBW would display the harmonic still
better at the expense of a massively extended sweep time.
Here, a compromise must be found between display quality
and measurement time, optimum for the actual measurement
task.
Fig. 4.6: Measuremen of the harmonic using the delta marker
4.3.3 Extended marker functions (PEAK SEARCH)
Press the key PEAK SEARCH in order to reach the extended
marker functions. Select the marker to be used with the key
(MARKER > 14 ). In the top screen area (where the level and
frequency values of the markers can be read) the lettering of
the marker selected will be shown pronounced bright.
Select the marker [2] and press the soft menu key PEAK. The
second marker should now jump to the same spot where marker [1] already resides (that is the position of the fundamental),
because the level of this is the highest. The values displayed
for (DELTA-) frequency and level should be “0”.
Fig. 4.5: Selection of the proper filter settings
Press the soft menu key NEXT PEAK in order to cause the active marker to position again on the first harmonic. The values
displayed for (DELTA-) frequency and level should be identical
to the original ones.

Quick introduction
the HMS will switch to the receiver mode and measures the level
of the center frequency set. The most important settings of the
measurement parameters are directly accessible in the main
menu of the receiver mode and can be activated by pressing
the appropriate keys.
Fig. 4.7: PEAK SEARCH function
4.4 Setting of the reference level
The reference level in spectrum analyzers is always the level of
the top graticule line. In order to realize the maximum dynamic
range in spectrum measurement, the level display range of the
spectrum analyzer should be fully used. This means that the
highest level in the actual spectrum should be as close to the
top graticule line (= reference level) as possible. The maximum
value of the level display (Y axis) of the measurement display is
determined by the reference level. However, take care that the
top graticule line is not exceeded as this would cause overdrive
of the spectrum analyzer input stage.
In order to prevent overdriving the input, the input attenuators
of the spectrum analyzer are independently selectable and
linked to the reference level. If the reference level in the amplitude selection menu (key AMPL 4 ) is increased by 20 dB (0 to
20 dBm), the input attenuator will be automatically switched to
30 dBm.This will cause the first harmonic of the signal (marker
2) to disappear in the noise floor.
Fig. 4.9: Receiver mode with a center frequency set
In the receiver mode the same bandwidths are available as in
the analyzer mode. Additionally, the bandwidths 200 Hz, 120 kHz,
and 1 MHz (–6 dB) for emi measurements according to CISPR
are provided (not available for HMS1000E). These can be chosen
by pressing the key BANDW and using the knob.
The HMS series receiver mode offers peak, average, rms and
quasi-peak detectors. The detector is selected in the main menu
of the receiver mode with the soft key DETECTOR.
The quasi-peak detector is not available for the
HMS1000E.
The measuring time is the time during which the spectrum
analyzer collects measurement results and combines them
for a result, depending on the detector selected. With the knob
the measuring time may be varied, or it can be entered directly
via the keyboard.
If the quasi-peak detector is selected, the measuring time should be >100 ms in order to measure
varying or pulsed signals correctly.
Fig. 4.8: Setting of the reference level
4.5 Operation in the receiver mode
For the measurement of levels of a signal frequency the HMS
series offers the receiver mode. The spectrum analyzer operates
like a receiver which is tuned to a frequency and measures the
level. The menu of the measurement functions will open by
pressing the key MEAS 11 , If the soft key CF > RX is activated,

6.1 Setting of the frequency (FREQ)
Pushing the FREQ key will call the menu for setting the frequency. The setting is performed as described in chapter 5.
Spectrum display needs to be parameterised before measurement is started. The two most important parameters are start
and stop frequency of the sweep. The start frequency sets the
frequency at the left border of the trace, the stop frequency
sets the highest frequency at the right hand border. In some
applications it is easier to modify the center frequency via the
CENTER key. In this case start and stop frequencies are automatically adapted. The step size of the center frequency can be
modified with CF-STEPSIZE. By pushing this soft menu key the
settings menu will open.
The UNCAL message disappears by using the trace
math.
The signal output of the tracking generator of the HMS1010/3010
shows no “true” sine wave signal. The output signal of the TG
is generally not sinusoidal in even spectrum analyzers from
other manufacturers. A generator which can generate a
uniform sinusoidal signal from 5 MHz to 1.6 GHz/3 GHz, is not
absolutely necessary to provide the desired function. The
shape of the signal output is frequency dependend. For the
“interpretation” at the input of the HMS does not require a
sinusoidal signal curve.
Through the reduction of the TG output signal to the input and
the use of HMS (view in relation) narrow-band filter, neither the
shape nor the signal harmonics of the signal are evaluated. The
correct function of the TG by using the HMS is ensured at any time.
–
0.1 x SPAN (Basic setting): The step size is always 1/10 of
the currently selected span (= 1 vertical division).
Since the existing tracking generator have to display frequencies
in a very broad context, it is customary that the tracking generator can not display low frequency signals (frequency range
5 MHz to 1.6 GHz resp. 3 GHz).
–
0.5 x SPAN: The step size is always 1/2 of the currently
selected span (= 5 vertical divisions).
6.3 Frequency range displayed (SPAN)
–
SET TO CENTER: The step size of the frequency is equal
to the present center frequency. This mode is especially
useful for the measurement of harmonics because each
step will move the center frequency to the next harmonic.
–MANUAL: Any step size is available. This allows the easy
measurement of spectra with regular frequency steps.
6.2 Aktivating/parameterizing the built in TG
The output of the tracking generators is nominal 0 dBm. It can
be reduced via an adjustable TG attenuator in 1 dB steps up to
–20 dBm (tracking generator attenuation). The tracking generator generates an output signal on the same frequency which
is currently received by the analyzer.
It is strongly recommended to deactivate the tracking generator,
whenever it is not required for the measurement. With activated
tracking generator, the instrument is not able to compensate
all imperfections any more. This will be indicated with a red „TG
on“ message on the bottom right of the display, as well as a
UNCAL message at the top of the display. The UNCAL message
disappears, once the trace mathematics (Chapter 6.7.1) of the
HMS is used to compensate the effects described above.
Performing measurements with the tracking generator
One of the most common application for TG measurements is
the spectral investigation of hardware components. For this
purpose, the DUT (device-under-test) is looped into the signal
path between TG output and receiver input. In order to compensate any influences caused by cables, adaptors etc. used at
the application, these will be directly connected to the spectrum
analyzer without the DUT in the loop.
The resulting trace shows the interference of the cables, connectors, etc. and needs to be stored in the trace memory of the
spectrum analyzer. Afterwards the trace mathematics (trace
- mem) shall be activated. Due to the mathematical compensation of all interferences, necessarily a straight line is displayed
and the UNCAL message is removed. After connection of the
DUT into the signal path, the frequency response of the DUT is
shown at the display, based on the selected frequency range.
46
Subject to change without notice
In principal there are two methods to define the displayed
frequency range: Defining start and stop frequency or center
frequency and span. The frequency range called span is the
range on both sides of the center frequency which a spectrum
analyzer displays on its screen. The span to be selected depends
on the signal to be analyzed, in general, it should be at least
twice as wide as the bandwidth of the signal.
The HMS series offers the following frequency ranges (Spans):
HMS1000E
1 MHz bis 1.6 GHz
HMS1000/1010 1 kHz bis 1.6 GHz
HMS3000/3010 100 Hz bis 3 GHz
Fig. 6.1: Hf signal modulated by a sine wave signal and the
resultant video signal vs. time
In zero span mode the spectrum analyzer acts similar to a receiver tuned to the center frequency. In this case the trace display
does not represent a spectrum but the amplitude over time.
In other words the spectrum analyzer behaves like a selective
oscilloscope. In order to select the full (maximum) frequency
range of 100 kHz to 1.6 GHz resp. 100 Hz to 3 GHz by pushing
once, the soft menu item FULL is provided. The soft menu key
LAST will restore the former setting (the last span setting). The
setting is performed as described in chapter 4.
6.4 Setting of the amplitude parameters (AMPL)
The key AMPL is used for all settings of the amplitude displayed.
The reference level (soft menu item REF.LEVEL) is identical to
the top graticule line of the display. The setting is performed
as described in chapter 5.

displayed at the upper trace screen boundary. The actual setting is shown in the third line left in the readout. Adjusting the
reference level automatically switches attenuator, gain and the
optional preamplifier. Lowering the reference level increases
sensitivity. Normally the reference level is chosen to display
the whole dynamic range on screen. For strong input signals
the reference level must be set high in order to prevent overdriving of the signal amplifier chain and in order to keep the
signal within the visible display window. For spectra with many
signals, the reference level should be so high that all signals
remain within the display area.
The receiver input will be overloaded by a disadjusted reference level.
Directly coupled to the reference level is the setting of the RF
input attenuation on the spectrum analyzer. If the reference
level is too high, the spectrum analyzer switches the RF attenuation automatically according to table 6.1, so the input mixer
can operate in the linear range at any time.
The basic unit (UNIT) of the reference level is dBm. Alternatively, the unit dBµV or (from firmware version 2.000) the linear
unit V and W can be selected by pushing the softmenu key and
using the knob. The scaling of the linear units V and W is set
dynamically.
If the linear unit V or W is selected, the reference
level is adjusted automatically.
The range (RANGE) defines the resolution of the amplitude
axis of the display. The basic scaling is in dB. The standard
scaling is 10 dB/DIV. In order to obtain a higher visual resolution, the spectrum analyzer also offers the scalings 5 dB/DIV,
2 dB/DIV, and 1 dB/DIV. A higher resolution does not increase
the accuracy, it only improves the readability. An appropriate
combination of reference level and vertical scale can be used
to get a more detailed display of the trace.
If the unit is set to dBm or dBµV, the scaling of the reference
level can be set to LIN % (linear percentage display). This
means that a logarithmic unit is represented as a percentage
value of the set reference level. This representation is useful
if, for example, in the time domain (span = 0 Hz) a modulation
of an AM-modulated carrier needs to be displayed.
The reference offset is used to vertically shift the trace if trace
math is switched on. The reference offset adds a selectable
value to the reference level. This is useful when prior to the
RF input, an attenuator or an amplifier is used. The input of
the reference offset is always given in dB, even if the reference
level is set to a different unit.
The setting of the reference level will also directly affect the
amount of RF attenuation at the input of the spectrum analyzer.
The attenuation setup menu is used to influence the thresholds
used for automatic attenuator selection when the reference
level is adjusted.
The instrument offers two different modes of coupling which
are selected via the softkey ATT-SETUP:
– LOW NOISE: When adjusting reference level switching
thresholds for attenuator and gain are optimised to get the
best signal/noise ratio.
– LOW DISTORTION: When adjusting reference level switching
thresholds for attenuator and gain are optimised for lowest
possible distortion.
If the unit contains the option „Preamplifier“ this soft key is
used to activate or deactivate the preamplifier (not available
for HMS1000E). The preamplifier increases the signal/noise
ratio by 10 dB (refer to chapter 13.1 for activate the optional
preamplifier). 6.5 Setting of the bandwidth (BANDW)
Spectrum analyzers resolve the spectral content of a signal
and display a frequency spectrum. The quality of the resolution
is determined by the resolution bandwidth. Additionally, the
spectrum analyzers offer a selectable video bandwidth. The
instrument will automatically (or, if desired, manually) choose
a slower sweep time if the span was set too wide for the RBW
(resolution bandwidth) selected (provided the user did not set
the span to manual operation).
The video bandwidth affects the smoothing (reduction of noise)
of the displayed curve. It is determined by the bandwidth of the

In contrast to the resolution bandwidth the video bandwidth
has no influence on the resolution properties of the spectrum
analyzer.

If the span was set manually too wide or the sweep
time to too high, the amplitudes will be displayed
with incorrect level; in such cases a red UNCAL
message will warn. The span must then be reduced
until the UNCAL message disappears.
RBW and the span settings may be chosen with the soft menu
key AUTO. The automatic mode will always set the sweep time
to the shortest possible value consistent with the correct
display of the spectrum content.
The HMS series will sweep the selected frequency range
continuously, i.e., after a sweep was completed, a new one will
be started and the display refreshed. If continuous sweeping
is not desired (e.g., if a single event shall be recorded upon
a trigger), there is also the possibility of selecting SINGLE
sweep. If single sweep is selected, the spectrum analyzer
will sweep the frequency range once or it displays the video
signal vs. time if the span is set to zero. The instrument will
only repeat the measurement after the soft key SINGLE was
pushed again. Additionally the soft menu TRIGGER offers
diverse trigger functions in order to react to events.
6.6.1SOURCE
With the submenu SOURCE an internal / external trigger source
or the video trigger can be selected.
The video trigger can be only activated in zero span
(span = 0 Hz).
By pushing the key BANDW you will enter the menu for setting
the bandwidths. Both the resolution bandwidth (RBW) and the
video bandwidth (VBW) may be set within the specified limits.
The table 6.2 shows the step sizes which are available.
Additionally automatic selection for both bandwidths (AUTO
RBW/AUTO VBW) may be chosen with the respective soft menu
key. The knob is used for the setting of the parameters.
Fig. 6.3: Signal with AM modulation 50% in zero span with linear
scaling
With a span setting of 0 Hz (zero span) the spectrum analyzer
changes the display from spectrum versus time to discrete
voltage versus time. The X-axis of the measurement diagram
represents the time axis, starting with time 0s and ends with
Fig. 6.2: The selections offered in the RBW menu
6.6 Setting of the SWEEP
At a frequency spectrum of f 1 0 Hz the sweep time is the time
the spectrum analyzer requires for sweeping the selected
frequency range to measure the spectrum. Certain limits have
to be observed (e.g. the resolution bandwidth set) in order to
obtain a correct display.
Pushing the key SWEEP will call the selection menu. The
SWEEP TIME can be varied within the specified limits. The
setting of the parameters is performed as described in chapter 5. In order to assist the user when setting the sweep time,
an automatic selection of the sweep time with respect to the

the selected sweep time. The minimum sweep time in zero span
mode is 2ms, the maximum is 1000s.
The video trigger allows to trigger on a defined signal level. This
so-called edge trigger works reliably up to a delta of at least
3 dB between the selected level (trigger line) and the applied
signal amplitude. The level of the video trigger can be set with
the soft menu key LEVEL.
6.6.2SLOPE
With the softkey SLOPE the sweep of an external trigger signal
will be started by a positive or negative edge; the external trigger
signal is applied via the BNC connector EXTERNAL TRIGGER
(TTL logic levels).
Use the respective soft key for the selection of the desired
trigger mode.
6.7 Curve display settings (TRACE)
– AVERAGE: The average level of consecutive measurements
will be displayed. In the standard setting, averaging will be
performed pixel by pixel and over the last measured curves.
The average mode is hence suitable for an improved display
of periodic signals close to the noise level
– HOLD: Freezes the curve being displayed, the measurement
will be terminated, this allows to subsequently use the
markers for the measurement of spectra.
6.7.1 Trace Mathematics
The sub function TRACE a MEMORY allows to transfer a curve
to the background curve memory; by pushing the soft menu
key SHOW MEMORY it will be displayed and can be compared
to the presently displayed curve. The stored curve will always
be shown in white and thus can be easily differentiated from
the presently displayed curve. In order to let the stored curve
disappear, push the SHOW MEMORY key again.
The trace menu can be opened by pressing the TRACE button.
The HMS series can simultaneously display up to 3 waveforms
on the screen. The trace mode of trace 2 and 3 is fixed and can
not be changed by the user.
Trace 1 = normal Sweep (yellow / free configurable)
Trace 2 = Max hold mode (purple)
Trace 3 = Min hold mode (green)
Trace 2 and 3 are each based on the freely configurable trace
1. Trace 2 and 3 can only be turned on or off.
If all traces are enabled, it‘s possible to analyze the signal
„progression“ by the resulting min-max graph.
Fig. 6.6: Display of a measured and a stored reference curve
The spectrum analyzer can subtract a stored curve from an
active curve and display the difference. If there is a curve
stored under TRACE a MEMORY the difference between the
stored an the active curves will be displayed by pushing the
soft menu key TRACE MATH. In order to let the stored curve
disappear push the key TRACE MATH and select OFF.
The TRACE MATH function can not be used in HOLD
mode.
Fig. 6.5: Simultaneous display of 3 traces
There are several modes of curve display (TRACE MODE):
– CLEAR / WRITE (basic setting): The previous curve will be
erased during a new sweep.
– MAX HOLD: The maxima of the curve being measured and all
previous ones will be displayed. MAX HOLD allows to easily
find intermittent signals in the spectrum or the maximum
values of varying signals.
– MIN HOLD: The minima of the curve being measured and all
previous ones will be displayed. MIN HOLD allows to recover
periodic signals out of the noise floor or to suppress intermittent signals.
Pushing the softkey TRACE MATH will call the menu of the
curve mathematics. After saving a trace in memory (via
the softkey TRACE a MEMORY) the difference between
this memory and the actual trace can be displayed using
the TRACE-MEM button. If there is a curve stored under
TRACE a MEMORY the difference between the stored an
the active curves will be displayed by pushing the softkey
MEM-TRACE. With the softkey OFF the saved waveform can
be faded out.
The curve in the memory (Memory Trace) will be
stored in the video memory as a bitmap. The spectrum analyzer hence will not adapt the stored curve
if the reference level or the displayed frequency
range are changed.

6.7.2 Detector
A detector converts the video signal of a spectrum analyzer
before it will be displayed. It functions pixel by pixel, determining
how the value of a pixel will be measured. Pushing the soft menu
key DETECTOR will call the settings menu for the selection of
various types of detectors.
– AUTO PEAK: The spectrum analyzer will display the maximum and minimum value of each pixel from the frequency
range represented by that pixel, no signal will be lost; if the
signal level fluctuates (noise), the width of the curve will
indicate the width of the signal fluctuations (Basic setting).
– SAMPLE: Only displays an arbitrary point within a display
pixel. The sample detector should be always used at span =
0 Hz, because this is the only method for a correct display of
the video signal vs. time. Can be used for the measurement
of noise power. For spans wider than than the resolution
bandwidth x 501, signals may be lost.
– MAX PEAK: In contrast to the auto peak detector this detector will deliver only the maximum value of the spectrum
within a pixel of the curve (e.g. the measurement of pulsed
signals or frequency modulated signals).
– MIN PEAK: Delivers the minimum of a spectrum within a
pixel of the curve. Sine wave signals will be displayed with
their correct levels while noise-like signals will be suppressed (e.g. for filtering sine wave signals from noise).
6.8 The use of markers
The HMS series offers several markers and delta markers
for the evaluation of curves. The markers are always tied to
the curve and indicate the frequency and the level at that. The
frequency position of the marker is marked by an arrow icon.
The nurmerical values of the frequency and the level are shown
as a “M” at the top of the screen. The unit of the level is the
same as the unit selected for the reference level.
The knob allows to choose up to 8 different markers. The individual markers can be switched on and off with the respective
soft menu key. The soft menu key POSITION is used to set the
frequency position of the marker along the trace. If marker
1 is activated, a frequency counter function can be enabled for
this marker by pushing the the soft menu key „COUNTER“. The
corresponding frequency value of the marker is now shown at
the top of the display marked with an „F“.
The delta marker level is always relative to the level of the
main marker (Marker 1), the unit of level is always dB. If a
marker is set to delta mode it is marked by a “D” in the read
out to distinguish it from a standard marker designated by a
leading “M”.
This button activates a submenu in which the active marker
can be set to the center frequency or the center frequency
can be set to the frequency of the active marker. Marker to
center (MKR TO CENT) allows to set the activated marker to
the center frequency. In contrast to marker to center allows
center to marker (CENT TO MKR) to set the center frequency
to an activated marker. A noise marker displays the noise at
the marker position. The REF TO MKR button allows to set the
reference level to the value of the current marker.
The spectrum analyzer calculates the noise power density in
dBm/Hz from the trace pixel values, the selected resolution
bandwidth and the detector. Noise power density can provide
useful information when measurements are made on noise
or digitally modulated signals. However, valid results are obtained only if the spectrum in the vicinity of the marker has a
flat frequency response. The function gives incorrect results
if measurements are made on discrete signals. Noise marker
mode is designated by a leading “N” in the marker readout.
Please note that the unit for the level measurement switches
from dBm to dBm/Hz. The noise marker can switch on/off with
a push on the softkey. The submenu All Marker Off can be used
to turn off all previous activated markers simultaneously. In
addition it‘s possible to switch off all markers by pushing the
softmenu button ALL OFF.
6.9 Peak-Search
The so called Peak-Search key will show the user the display of
the next maximum value. The button PEAK SEARCH activates
a menu which is used to detect peaks in the trace and assign
markers to them:
–PEAK: this function places the marker or the delta marker on the highest peak of the trace; the function acts on
the active marker, which is activated in the marker menu
before.
– NEXT PEAK: this function places the marker or the delta
marker relative to their current positions on the next lower
peak of the trace; the function acts on the active marker,
which is activated in the marker menu before.
– NEXT LEFT: this function places the marker or the delta
marker relative to their current positions on the next left
peak of the trace; the function acts on the active marker,
which is activated in the marker menu before.
– NEXT RIGHT: this function places the marker or the delta
marker relative to their current positions on the next right
peak of the trace; the function acts on the active marker,
which is activated in the marker menu before.
–MINIMUM: this function places the marker or the delta
marker on the lowest value of the trace; the function acts
on the active marker, which is activated in the marker menu
before.
– ALL TO PEAK: This function will set all markers to the
highest peak; from this point a new arrangement can be
realized easily.

6.10 Limit Lines
Limit lines are used to set limits for level characteristics
versus time or versus frequency on the display. They must
not be exceeded. For instance, the upper limits of permissible
spurious or harmonics of a DUT are marked by limit lines. In
the HMS series, the upper and lower limit value can be preset
by way of limit lines.
Pushing the button LINES will call the setting menu to set
limit lines. The softkey UPPER LIMIT activates / deactivates
the upper limit line which is displayed as a red line. After
activating the softkey UPPER POSITION the amplitude value
for the upper limit line can be set via the knob. The softkey
LOWER LIMIT activates / deactivates the lower limit line which
is displayed as a red line. After activating the softkey LOWER
POSITION the amplitude value for the lower limit line can be
set via the knob.
Additionally, the softkey BEEP activates an acoustic signal
which warns as soon as the trace leaves the amplitude range
defined by the upper und lower limit line. The softkey MESSAGE activates a message in the upper left corner of the trace
display which shows if the whole trace is inside (pass/green)
or outside (fail/red) the amplitude range defined by the upper
and lower limit line.
6.11 Measure Menu
The button MEAS opens the measure menu with different options. The softkey CF a RX opens the receiver mode tuned to
the actual center frequency. The softkey M1 a RX opens the
receiver mode tuned to the actual frequency of marker 1.
The softkey button REFLECTION CAL starts the calibration
wizard of the reflection measurement.
The reflection measurement menu is only available
with HMS1010 and HMS3010.
To use the wizard, the HAMEG VSWR bridge HZ547 is recommended. The VSWR bridge HZ547 allows the measurement of the
voltage standing wave ratio (VSWR) and the reflection coefficient of
50 Ω devices. The frequency range is 100 kHz to 3 GHz.
The HMS1010 resp. the HMS3010 guides the user through all
steps of the reflection measurement sequentially. Concerning
the reflection measurement you have to connect the VSWR
measuring bridge to the spectrum analyzer. The tracking ge-
nerator (TG) will be switched on automatically, if you don‘t have
activated it already.
Before starting the wizard, the user is able to select
a trace detector. The selected detector will be used
during the measurement.
The signal source (tracking generator / OUTPUT) needs to
be connected to the IN connector of the VSWR bridge. The
OUT terminal of the bridge needs to be connected to the
input (INPUT) of the spectrum analyzer. At first, you have
to let the DUT terminal open which equals total mismatch.
Afterwards, a short calibration measurement will perform. A
review of these two signals with the trace math will illustrate
that both measurements are phase shifted by 180°. The white
waveform describes the open calibration measurement, the
yellow waveform describes the short calibration measurement. Based on the trace math (TRACE - MEM) a total compensation of the measurement deviation is archieved and the
deviation of the device under test to a zero measurement
will be shown now.
The measured reflected energy by the spectrum analyzer
which will now indicate the algebraic difference between both
measurements in dB which is the desired return loss. Once the
return loss has been determined use the table on the VSWR
measuring bridge to read the REFLECTION COEFFICIENT and
the VSWR. More detailed information about the VSWR measuring bridge HZ547 you can find in the appropriate manual which
can be downloaded from our homepage www.hameg.com.
6.12 Auto Tune
The AUTO TUNE button forces the HMS to perform a scan at
full span, locate the maximum peak value and center it in combination with applicable RBW and span settings on the display.
The AUTO TUNE function is a comfort function to aid the
user. The closer the signal level is located to the general
noise floor, the harder the peak is detectable for the AUTO
TUNE algorithm. Therefore, it is possible that the settings
must be slightly adjusted by the user. This process can hold
up few seconds.
6.13Receiver-Mode
6.13.1 Display layout in receiver mode
By pushing the MODE key the selection menu will be called
which allows to switch between sweep mode (analyzer mode)
and receiver mode. The spectrum analyzer acts as a receiver
which measures the level at a preselected frequency. The most
important parameters such as e.g. frequency, amplitude, resolution bandwidth may be set using the appropriate keys and
can be vary via knob or numerical keyboard.
6.13.2 Operation in the Receiver-Mode
In the receiver mode the same bandwidths are available as
in the spectrum analyzer mode. Additionally the bandwidths:
200 Hz, 9 kHz, 120 kHz and 1 MHz are available for emi emission measurements according to CISPR (not available for
HMS1000E).
Following detectors are available in the receiver mode and can
be set with the softkey menu DETECTOR:

–QPEAK: the quasi-peak detector evaluates the measurement signal according to the evaluation curves defined in
the CISPR standard (not available for HMS1000E).
– RMS: the RMS detector takes the rms value of the measurement signal during the set measurement time.
With the soft menu item AUDIO the HMS series offers an AM and
a FM demodulator allowing listening to modulated signals. The
demodulated signal may be listened to with a headphone and an
intern speaker. The headphone is connected to the headphone
connector (3.5 mm female connector). If the headphone is activated, the intern speaker will be deactivated. The respective
soft menu keys allow to switch the demodulator on or off and
to set the volume.
The key FREQ and the softkey DETECTOR selects the detector
(Peak, RMS, Average and Quasi-Peak). The measurement
time is the time during which the spectrum analyzer collects
measurements and combines them according to the detector
selected for a display.

Connections
10 Front panel Connections
11 Rear panel Connections
10.1 USB connector
11.1 USB connector
Using the front panel USB connector a software update of the
HMS firmware can be performed or screenshots can be strored. Please use only FAT or FAT32 formatted mass memory
(chapter 9.6).
The USB interface on the rear panel can be used to connect a
printer (see chapter 9.4).
10.2PHONE
In addition the rear panel of the spectrum analyzer also holds
the standard DVI-D connector for the connection of external
monitors or projectors. The DVI-D connector only provides digital signals, therefore an analog input of a monitor or projector
cannot be used to connect the analyzer. The HMS series delivers
a DVI signal in VGA resolution (640 x 480), so any standard TFT
monitor can be connected. Modern flat screens will interpolate
the signal providing a full screen image. When connecting
a projector to the HMS please make sure to select a type of
projector that has been designed for the use with computers/
notebooks, as these projector will be able to handle the VGA
resolution of the HMS.
The signal available at this connector comes from an AM detector and it helps to identify the sources of interference e.g.
when making precompliance measurements. If an antenna is
connected to the analyzer input, selecting CENTER and using
the knob the analyzer can be tuned to a transmitter (Receiver
mode chapter 6.13). The demodulation has to activated. Please
note that this operational mode may be subject to national
restrictions!
10.3 PROBE POWER
This connector can be used as a supply (6 VDC) e.g. for HAMEG
probes. The inner contact is +6 V, the outer contact is connected
to the instrument housing and thus with the measurement
inputs’ ground potential and also protective earth (PE).
11.2 DVI connector
DVI-VGA adapters as well as DVI-composite adapters are not supported. You might encounter
difficulties when connecting the HMS to an HDTV
set through an HDMI adapter, as most HDTV sets
expect an HDMI signal of 720p and higher.
10.4 EXTERNAL TRIGGER
11.3 REF IN / REF OUT
The external trigger input connector is used for the control of
measurements by an external signal. (TTL levels.)
In order to further increase the frequency stability, the internal oscillator may be replaced by an external one which can
be connected to the 10 MHz REF IN/REF OUT connectors on
the rear panel. The external reference frequency signal must
comply with the specifications given with respect to frequency
accuracy and amplitude.
10.5 OUTPUT 50Ω (Tracking Generator)
The tracking generator output (only HMS1010 and 3010) has to
be connected to the measuring object with a N connector cable.
A test signal with a spectrum from 5 MHz to 1.6 GHz resp. 3
GHz is available.
The switching between internal and external reference frequency can be effected via the button SETUP and the softkey
REF. FREQUENCY.
10.6 INPUT 50Ω
Without attenuation (ATT 0 dB) 80 VDC must not be exceeded.
With an attenuation of 10 to 50 dB, the maximum level is
+20 dBm. Levels or DC voltages above the values mentioned
may destruct the input stage. The outer contact is connected
to the instrument chassis and thus to safety ground (PE). The
maximum input levels resp. voltages must not be exceeded.

Remote Control
12 Remote Control
The HMS series is basically supplied with an USB/RS-232
interface. The respective drivers are available on the enclosed
Product CD or can be downloaded at http://www.hameg.com.
To establish a basic communication a serial cable (1:1) as well
as a terminal program like Windows HyperTerminal is required.
The Windows HyperTerminal program is part of any Windows
operating systems. A detailed instruction how to setup a basic
communication using HyperTerminal is available at the HAMEG
Knowledge Base at http://www.hameg.com/hyperterminal.
The HMS series uses SCPI (= Standard Commands for Programmable Instruments) for remote control. Remote control
is possible via the built-in dual interface USB/RS-232 (options:
Ethernet/USB, IEEE-488). This allow access to nearly all functions which are available on the front panel. A detailed document
about the provided SCPI commands is available at http://www.
hameg.com.
12.1 RS-232
The RS-232 interface is made as a 9 pole D-SUB connecter. Over
this bidirectional interface you can transfer settings, data and
screen dumps from an external device (PC) to the power supply
or vice versa. The direct physical link between the instrument
and serial port of the PC can be done via an 9 pole cable with
shielding (1:1 wired). The maximal length must below 3 meter.
The exact pinning oft he plug is as follow:
Fig. 12.1: Pin Assignment RS-232
12.2USB
All descriptions regarding the USB interface are
true for the HO720 interface card as well as for the
optional HO730 USB part. All currently available
USB driver are fully tested, functional and released
for 32 Bit and 64 Bit Windows™ systems.
The USB interface must be chosen in the instrument and does
not need any setting. At the first connection Windows™ ask
for a driver. The driver you can find on the delivered CD or on
our homepage www.hameg.com at the download area for the
HO720/HO730. The connection can be done via the normal USB
or via the virtual COM port (VCP). The description how to install
the driver you can find in the HO720/HO730 manual.
If the virtual COM port will be used, you must set
USB as interface at the power supply.
12.3 Ethernet (Option HO730)
The optional interface card HO730 does have a USB and Ethernet connection. The settings of the parameters at the instrument are done after selecting ETHERNET as the interface. You
can set anything including a fix IP adress. Alternative you can
chose a dynamic IP setting via the DHCP function. Please ask
your IT department for the correct setting at your network.
If DHCP is used and the HMS does not get any IP
adress (f.e. if no ethernet cable is connected to the
scope or the network does not support DHCP) it may
take up to three minutes until a time out make the
interface available again for configuration.
If the instrument does have an IP Adress you can open your web
browser and put this IP adress into the adress line (http//xxx.
xxx.xxx.xx). Since the HO730 does have a webserver integrated
it will open a site with informations about the HMP, the interface and it’s setting. On the left side there are links to „Screen
Data“ which make it possible to transfer a screen dump to
the PC (using the right mouse click this can be transferred to
the clip board for further use). The link „SCPI Device Control“
open a site with a console to send remote SCPI commands to
the power supply.
The pin assignment:
2 Tx Data (Data from the HAMEG device to the PC)
3 Rx Data (Data from the PC to the HAMEG device)
7 CTS Ready to send
8 RTS Ready to receive
5 Ground (Reference potential connected via the HAMEG
instrument of safety class I with the line cord and thus to
the safety earth of the wall outlet)
9 +5 V Supply voltage for external devices (max. 400 mA)
The maxiaml amplitude at Tx, Rx, RTS und CTS is ±12 Volt. The
standard RS-232 settings are:
8-N-1 (8 data bits,no parityt, 1 stop bit), RTS/CTS-Hardwareprotocol: none.
In order to set these parameter at the instrument, please press
the button MENU and choose the menu item Interface. Make
sure the RS-232 interface is chosen (menu text marked with a
hook) and then choose the menu item Interface Settings.
This opens a menu where you can set all parameters for the
RS-232 communication.
