12.1 Activation of the PreamplierHO3011
The Preamplier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
preamplier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ndinthemanualHZ46onourhomepage

12.4 NeareldprobeHZ530/HZ540
The set includes 3 hand-held probes with a built-in preampli-
er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eldsandperformshieldeffectivenesscomparisons.

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specicationsare
