Introduction
vouchers R&S®HV110, R&S®HV111 and R&S®HV112 allow
for an upgrade at a later date via licence key. The installed
options and vouchers can be verified under
DEVICE
INFORMATION in the SETUP menu.
Once you have entered the voucher code on the
homepage http://voucher.hameg.com, the licence key will
be generated („SERIAL NUMBER.hlk“). The ASCII file may
be opened with an editor. This allows you to read the
actual key in plain text. You can choose between two
methods to enable the desired option with this key: an
automated reading or manual input. The automated
reading via USB stick is the fastest and easiest method.
Store the licence file on a
USB stick and then install it to
the instrument using the FRONT USB port. Press the
SETUP key in the GENERAL section of the HMO control
panel to open the SETUP menu. You will find the
LICENCES menu on page 2|2. Press the soft menu key
READ KEYS from licence file to open the file manager.
Select the required licence file with the universal knob in
the CURSOR/MENU section and then use the soft menu
key LOAD to load it. This will load the licence key, making
the option instantly available by restarting the instrument.
Alternatively, you can enter the licence key manually.
Select the menu UPGRADE and press the soft menu key
INPUT KEY manually. This will open an input window. Use

the universal knob in the CURSOR/MENU section and the
ENTER key to enter the licence key manually. After
entering the complete key, press the soft menu key
ACCEPT to confirm the entry. The option will be activated
after restarting the instrument.
The R&S®HMO1002 resp. R&S®HMO1202 series is prepa-
red for mixed-signal operation and have the appropriate
connectors on the front panel. Connecting an 8-channel
logic probe R&S®HO3508 equips the scope with 8 logic
channels.
2 .8 Self Alignment
The R&S®HMO1002 resp. R&S®HMO1202 series features
an integrated self alignment procedure to achieve the
highest possible accuracy. During the standard self align-
ment the instrument adjusts vertical accuracy, offset,
time
base and several trigger settings and saves the identified
correction data internally. To start the self alignment in the
SETUP menu, press the soft menu key SELF ALIGNMENT
and press the START key. The procedure will run for about
5-10 minutes. Each step and its corresponding progress
will be shown in a bar display.
2 .8 .1 Logic Probe Self Alignment
The self alignment for the optional logic probe
R&S®HO3508 primarily aligns the switching levels. To start
the self alignment for the logic probe, it is necessary that
the logic probe type R&S®HO3508 is connected to the
R&S®HMO1002 resp. R&S®HMO1202 series. It is impera-
tive that the bit connectors are not connected. To start the
The instrument must have reached the required operating tempe-
rature (switched on for at least 20 minutes) and all inputs must
be unused, in other words all cables and probes must be removed
from the inputs.
