12 Optional Accessories

12.1 Activation of the Preamplifier HO3011
The Preamplifier for the series HMS (DANL –135 dBm typ. / 100
RBW) will activate in the Setup menu with the softkey UPGRADE.
Please look at chapter 8.7 for the procedure of the upgrade. This
preamplifier isn't included in the supplied accessories and can
be acquired by purchase.
12.2 19'' Rack mount kit 4HE HZ46
For the application in rack systems HAMEG provides a kit for
the HMS series. Technical details and a description about the
mounting you can find in the manual HZ46 on our homepage
http://www.hameg.com/downloads.
12.3 Carrying case HZ99
The Carrying Case HZ99 is used to transport your spectrum
analyzer and is available ‚on stock'.

12.4 Near field probe HZ530/HZ540
The set includes 3 hand-held probes with a built-in preampli-
fier covering the frequency range from 100 kHz to 1 GHz resp.
!1 MHz to 3 GHz. When used in conjuction with a spectrum ana-
lyzer or a measuring receiver, the probes can be used to locate
and qualify EMI sources, as well as evaluate EMC problems at
the breadboard and prototype level. The power can be supplied
either from batteries (HZ530) or through a power cord directly
connected to an spectrum analyzer (HZ540). Signal feed is via
a BNC-cable or SMA/N-cable. They enable the user to evaluate
radiated fi elds and perform shield effectiveness comparisons.
The probes – one magnetic field probe, one electric field probe
and one high impedance probe – are all matched to the 50Ω
inputs of spectrum analyzers. The technical specifications are
described in the HZ530/HZ540 manual on our homepage http://
www.hameg.com/downloads.

12.5 Measurements of spectra with a VSWR bridge
HZ547 (HMS1010/3010)

Fig. 12.2: VSWR bridge HZ547 for HMS1010/3010

The VSWR bridge HZ57 allows the measurement of the voltage
standing wave ratio (VSWR) and the reflection coefficient of 50Ω
devices. Typical objects are e.g. 50Ω attenuators, load resistors,
amplifiers, cables, mixers, frequency selective devices. The
frequency range is 100 kHz...3 GHz. The technical specifications
and the measurement set-up are decribed in the HZ547 manual
on our homepage http://www.hameg.com/downloads.
12.6 Transient Limiter HZ560
The Transient Limiter HZ560 protects the input circuit of
spectrum analyzers and measurement receivers, in particular
in combination with the use of a Line Impedance Stabilization
Network (i.e. LISN HM6050). The technical specifications are
decribed in the HZ560 manual on our homepage http://www.
hameg.com/downloads.
12.7 75/50-Ω-Converter HZ575
The converter HZ575 has a 75Ω AC coupled input and a 50Ω DC
coupled output. Using HZ575, spectrum analyzers with 50Ω input
can be used for measurement in 75Ω environment. HZ575 can
be used reversed too. A 50Ω signal applied at the 50Ω "output"
is present at the 75Ω BNC "input" socket with an impedance
of 75Ω. The technical specifications are decribed in the HZ575
manual on our homepage http://www.hameg.com/downloads.
