General information regarding the CE marking
HAMEG instruments comply with 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 emmission 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 cables HZ72S and HZ72L
from HAMEG are 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. RF immunity of Spectrum Analyser
4.1 Electromagnetic RF field
Although the interior of the spectrum analyser is screened by the cabinet, the influence of electromagnetic RF fields may become
visible, if the field intensity under the present environmental condition is high. The device under test as well as the measuring cable
may also receive such signals.

Preparing for Operation
6. Preparing for Operation
6.1 Stand
Utilize the stand on the back to use the screen in an easier-to-
see angle on the desk.
6.2 Connection to power supply
The MA300 AC adapter is both for the use with AC power supply
and for charging the MB300 built-in battery (charge is started
automatically if AC adapter is connected).
Connect the adapter as in the figure below and connect the AC
plug to the power line (100 to 240 VAC, 50/60 Hz). For static
electricity protection, ground the unit by connecting the three
cores if possible. Not grounding the unit can damage it and the
object measured. Do not use an AC adapter other than the MA300
supplied with the unit. Using an AC adapter other than the MA300
may cause damage to the unit.
Battery full charge time: approx. 8 hours
Battery operate time: the longest 120 min (back light OFF)
Battery full charge time with MBC300:approx.120 to 150 min
When it is not operated at normal temperature and setting
parameters is the initialization.
If the voltage of a battery becomes low at the time of battery
operation, it will be displayed on a screen as „Low Batt“,
and a buzzer will sound (it sounds, even if it is set up so
that a buzzer may not sound), and a power supply will be
shut off within several minutes. At that time, since the
switch is the position of „ON“, please push once and return
to the position of „OFF“. If it is with the position of „ON“
after a power supply is shut off, it discharges inside, will be
in electric overdischarge state, and becomes the cause of
contracting the life of a battery. Please take care.
Moreover, under low temperature (near 0 ºC), since a battery
performance falls and voltage becomes low, even when capacity
remains enough, it may display on a screen as „Low Batt“.
When a battery repeats charge and electric discharge, the
fall (the fall of capacity and increase in internal resistance) of
a battery performance begins from about 200 times, and
capacity falls to the original half by about 500 times also
under good conditions. On bad conditions (high temperature,
etc.), the life of battery will be shorter than this.
6.3 Replacing the fuse
5 A / 250 V fuse (IEC127-2 sheet3, slow-blow type) is used for
the battery power supply. When replacing it, turn the power off
first, disconnect the AC adapter, remove the battery cover and
on the back as shown in the figure below, remove the battery,
and then take sufficient care to perform the replacement.
Be sure to use the fuse supplied with the unit, or specified one.
6.4 Installing the battery
When installing the battery, turn the power off first, disconnect
the AC adapter, open the battery cover on the back of the unit
after removing the two screws as shown in the figure below,
and then take sufficient care to perform the installation. Be sure
to use the specified battery, MB300.
6.5 Soft carrying case
When carrying the unit or using it outdoors, the soft carrying
case is convenient. You can also carry the AC adapter and printer
with it, putting them in the accessory pouch.
Avoid using the unit in the soft carrying case in places where
temperature is high because, with the soft carrying case,
the temperature inside becomes higher than the ambient
temperature.

9.4 Relation between the reference level and
ATT · AMP (in dBm indication)
The programmable attenuator (ATT) and the input amplifier (AMP)
inside HM5033 are automatically set according to the setting
value of the reference level (REFER). ATT cannot be set
independently.
When the input signal level is higher than the suitable level
for 1st mixer’s terminal, it generates harmonics distortion
and spurious. HM5033 is designed so the input signal level
of 1st mixer is determined between -20 and
-25 dBm by the reference level. An input level to 1st mixer
is calculated for by the following formula.
Input level of 1st mixer [dBm] = Input level [dBm] - (Fixed ATT
+ Insertion loss [dB]) – ATT [dB] + Input AMP [dB]
„(Fixed ATT + Insertion loss [dB])“ is always 5 dB.
9.5 Setting the offset level
1. Press
F5
and use to set the offset of reference level.
When amplifier and attenuator are used externally, display level
can be matched by offset.
The setting range is from -50.0 to 50.0 dB (0.1 dB step).
Offset is calculated to the reference level, and it is displayed.
When offset is set, it is displayed on LEVEL display area
as „OFS“.
Furthermore, the value of a marker point is displayed reflecting
the calculated offset.
Offset of dB µ V, dBmV, dBV, W, etc. are changed
automatically.

place at which data is saved.
It can be overwritten, too.
18.4 Loading the data
1. Press
F4
to read out the data at the set number.
This reads out the trace whenTRACE is selected.The setting
parameter of the loaded trace is displayed in the loaded
trace information display area. (Refer to „4. Description of
Display“ for details)
This reads out the setting parameters when PARAM is
selected.
When you load a trace, the current trace disappears, the
HOLD state is set, and the loaded trace is displayed. For
the loaded trace, you can use the marker, but cannot use a
measuring function. When you press the HOLD/RUN key,
the loaded and the current traces are displayed overlapping
each other.
„*“ is displayed on the right end of the number of location

Once you select the measuring function, pressing
MEAS
next time will directly bring up the function
screen for the function you selected the last time. If you
want to stop the measuring function, or if you want to
select another measuring function, press [F6] (MEAS
OFF). This stops the measuring function and switches to
the above screen, which allows you to select the
measuring function.
The measuring function is stops, when push
MKR
while these 4 functions (Channel power ,Adjacent channel
leakage power, Occupied frequency bandwidth,
Frequency counter) are selected. Because each 4
functions and marker operation cannot be used
simultaneously. Similarly, the function of the marker
stops, when the functions of these 4 measurements are
selected while using the marker.
The unit displays data in 251 horizontal dots, but it
internally captures the trace and calculates the measured
value (Channel power measurement, Adjacent channel
leakage power measurement and Occupied frequency
bandwidth measurement) in 1001 dots.
19.1 Channel power measurement
<Ch Power>
