9.7 Upgrade of software options (voucher)
The R&S®HMS-X can be upgraded with options (voucher)
which will become accessible after inputting a licence key.
The following vouchers are available for the R&S®HMS-X:
❙ R&S®HV211 : Unlock built-in tracking generators (TG)
❙ R&S®HV212 : Bandwidth upgrade to 3 GHz
❙
R&S®HV213
: EMC option incl. preamplifier
After purchasing the voucher the licence key can be
generated via http://voucher.hameg.com. This file is an
ASCII file and can be opened with an editor, then the true
key can be read. There are two methods for employing the
key to use the desired option: the automatic or the manual
input. The fastest and simplest method is the automatic
input: first store the file on an USB stick, then conect the
stick with the front panel USB port and press the key
SETUP. The SETUP menu will open. Select page 2|2 and
the softkey Upgrade to open the upgrade menu.
The softkey READ LICENCE FILE opens the data manager.
Use the knob to select the correct file and press the soft-
key LOAD. This will load the licence key; the option will be
ready to use immediately after a restart of the instrument.
Alternatively, you can use the manual input of the licence
key. Select the menu UPGRADE and press the softkey
MANUAL KEY INPUT. Use the knob and the ENTER-key to
input the licence key. After input of the complete key ple-
ase press the softkey ACCEPT in order to input the key into
the system. The option will be activated after a restart of
the instrument.

Connections
10.1 USB stick connector
Using the USB connector on the front or the rear side a
software update of the R&S®HMS-X firmware can be per-
formed or screenshots can be strored. Please use only FAT
or FAT32 formatted mass memory (chapter 9.6). Additional
information about the firmware update or the storage of
data you can find in chapter 7 and 9.
10.2 PHONE connector
The signal available at this connector comes from an AM
detector and it helps to identify the sources of interfe-
rence e.g. when making precompliance measurements. If
an headphone is connected to the analyzer input, selec-
ting Center and using the knob the analyzer can be tuned
to a transmitter (Receiver mode chapter 6.13). The demo-
dulation has to activated. Please note that this operational
mode may be subject to national restrictions. A 3.5 mm
jack is provided for headphones. The internal impedance
of the connector is approx. 10 E.
10.3 PROBE POWER
This connector can be used as a supply (6 V
DC
) e.g. for
HAMEG probes HZ540 or HZ550. 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).
10.4 EXTERNAL TRIGGER
The external trigger input connector is used for the con-
trol of measurements by an external signal. The external
trigger signal is applied via the BNC connector EXTERNAL
TRIGGER. The trigger threshold is similar to TTL signals.
More information about the external trigger signal you can
find in chapter 6.

delay can not be defined.
